1. General

1.1 Overall presentation of project Shanghai Meishan Iron and Steel Co., Ltd. (hereinafter referred to as Meishan Iron and Steel Company), formerly affiliated to Shanghai Economic Commission, is an enterprise with sole state investment. Meishan Iron and Steel Company became a subsidiary of Baosteel Co., Ltd. when it was formed by the state in 1998, and in May 2005, it became a holding subsidiary of Baosteel Co., Ltd., as one of the 512 large scale state-owned enterprises receiving prior support by the State Council. During the 1990s, with the approval by the State Planning Commission, Meishan Iron and Steel Company used national loans with discounted interest rates in the technical transformation for over a decade in succession, and the production and technical equipment and the automatic control level of the Company reached the advanced level in China, some reaching the advanced international level, especially in the construction of steel melting, continuous casting, hot rolling and blast furnace system projects and the associated works, thus greatly upgrading its actual production capacity, and the technical content and added value of products. Meishan Iron and Steel Company has become a large scale iron and steel complex with the complete production flow of coking, sintering, iron melting, steel melting, continuous casting and steel rolling. In 2004, Meishan Iron and Steel Company had total assets of 13,225 billion yuan, and its steel output reached 3 million tons. At present, although Meishan Iron and Steel Company has the overall production capacity of 2,980,000t/a iron, 3000,000t/a steel and 2,890,000t/a hot rolling plates and coils, with the equipment reaching the advanced level in the country, it can only produce hot rolling products because its product matrix is not quite rational, therefore its profitability ability is not strong, and it is vulnerable to market risks. In the meantime, as Meishan Iron and Steel Company was one of the iron making bases of Shanghai before it became a subsidiary of Baosteel in 1998, its systems for making iron already had a long operation life and the key production facilities have become aged, with equipment level at comparatively backward level, and they have the problems of high overall energy consumption, low comprehensive utilization rate of resources and poor environmental quality. According to the new industrial policies of the state, the requirements for sustainable development of national economy and the strategies of Baosteel Co., Ltd. for its new round of growth, Meishan Iron and Steel Company will take the opportunity of Baosteel Co., Ltd. to speed up the construction of high quality steel products manufacture system and to further advance the construction of high grade steel plate production base, make the upgrading and transformation of system equipment upgrading as the start point on the platform of rational, professional and large scale division of work in Baosteel, introduce new processes, new technologies and new equipment to a rational extent with the world first-rate iron and steel production technological and research and development ability of Baosteel, to further reduce the overall energy consumption, improve the environmental quality and increase the overall

competing power of Meishan Iron and Steel Company.

In overall consideration for the planning of Baosteel Co., Ltd. as a whole, the product varieties and sizes of these systems should be well arranged for complementary supply, and the products should have their own characteristics. For the 1700 class thin slab continuous casting tandem rolling to be built in Meishan Iron and Steel Company, to bring into full play the process characteristics of thin slab continuous casting tandem rolling, the products to be made will be medium and low grade non-oriented silicon steel, steel for building purpose and special-purpose steel. The thin slab continuous casting tandem rolling mill is good at making extra-thin extra low carbon steel coils with ferrite production process, to really realizing substituting some cold rolling products with hot rolling products. It is also possible to further develop and produce extra low carbon and extreme low carbon steel and Phase Transformation Induced Plasticity (TRIP) steel and dual phase (DP) steel coils for automobiles. 1.2.4 Analysis of compatibility of the proposed project with overall urban planning According to the “Overall urban plan for Nanjing Municipality” (1991~2010), the function of Banqiao New Town (location of the proposed project) is set as a comprehensive industrial town in the metropolitan development zone, and its industrial function is set as: the metallurgical, machine building and processing industries and commercial and trading will be encouraged, and construction of projects with serious pollution to water body is prohibited. In the “Main points of overall planning for Banqiao New Town”, it is pointed out that, for the near term, with the Banqiao Subdistrict and Shanghai Meishan Iron and Steel Co., Ltd. of Baosteel as the backup, the emphasis of development will be placed on the area to the west of Nanjing – Wuhu highway and to the north of Meishan Iron and Steel Company, and for the far term, it will expand gradually from the north to the south and from the west to the east. With the traffic corridor from Nanjing to Wuhu, the dedicated railway line for Meishan Iron and Steel Company and natural topography, Banqiao New Town is divided into three major functional blocks: Yuhua Economic and Technological Development Zone block (northwest block, land for industrial use), Meishan block (southwest block, land for industrial use) and east town block (land for residential purpose). The northwest block is a processing industrial park mainly for industries, warehousing and urban engineering facilities, the southwest block will mainly for Meishan Iron and Steel Company and its extended processing industries, and the east town block is mainly for residential and living purpose. 12

In the “Overall plan in development of areas along the Yangtze River of Nanjing Municipality”, the industrial development goals are set as: to achieve substantial results in internationalization, modernization and scale growth of industries, markedly upgrade the industrial competing power, and basically form the overall framework as an advanced manufacturing base of world level. The industries will be further concentrated, the industrial competing superiority in the province and in Yangtze River Delta will be set up, and the sales income of five main industrial sectors of petrochemical, electronics and IT, automobiles, iron and steel and power generation in 2010 will be redoubled than that of 2002, being 500 billion yuan, with the total investment during 2003 ~ 2010 being about 300 billion yuan. The five main industrial sectors of petrochemical, electronics and IT, automobiles, iron and steel and power generation will be made bigger and stronger by adhering to the strategy of taking industry as the primary for new type of industrialization, and advancing the construction of industrial clusters along the Yangtze River. For the iron and steel industry, the superiority of the golden waterway and the existing industrial foundation should be brought into play, to speed up the pace of internationalization, modernization and scale growth of the industry, and foster it as an important pillar industry in Nanjing. The product matrix shall be adjusted and products upgraded, to form product series, with emphasis on the development of wide medium and thick plates, hot (cold) rolling stainless steel sheets (coils), corrosion resisting coated plates and other refined and high quality products. It can be seen from the above analysis that the proposed project conforms to the overall development planning for Nanjing. 1.2.5 Analysis of compatibility of the proposed project with environmental planning In the “Environmental protection plan in development of areas along the Yangtze River of Nanjing Municipality”, it is pointed out that industrial enterprises with serious pollution to water should be arranged downstream the city and water source, and industrial enterprises with serious air pollution should be arranged in the leeward direction of the city. According to the cyclic economy mode, industries with no or little pollution and high added values will be encouraged, to realize zero increase and even decrease in total pollution while maintaining rapid economic growth. Environmental impact assessment and the “three simultaneousness” system will be strictly implemented, to strengthen the control of total amount of pollutant and the efforts on pollution rectification. High and new technologies will be adopted to transform traditional chemical and metallurgical industries, clean production technologies be promoted, and the certification of ISO14000 environmental management series standards will be pushed ahead. The proposed project is for metal melting and rolling industry, which produces serious air pollution. Banqiao where the proposed project is located is in the leeward direction of Nanjing urban area, therefore the site location conforms to the principle in “Environmental protection plan in development of areas along the Yangtze River of Nanjing Municipality” that industry with serious air pollution should be arranged in the leeward direction of the city whenever possible.

2. General conditions the proposed project and pollution factor

analysis

2.1 Necessity of project construction (1) Briefs of existing project Meishan Iron and Steel Company now has 3×65-duct coke ovens, 2×130m2 + 1×180m2 sintering strants, and 2×1250m3 + 1×1280m3 blast furnaces, with an annual production capacity of molten iron of 3,000,000t; the steel melting system consists of 2×150t converters, one RH furnace, one LF furnace; the continuous casting system consists of 2 slab continuous casting machines, for annual output of slabs of 3,000,000t; the rolling plant is equipped with a 1422mm hot rolling mill, with a production capacity of 3,000,000t. The Company has completed the transformation for the finish rolling and coiling systems for hot rolling, and the technical level of its main production equipment has reached the advanced level in China. For the proposed project one thin slab continuous casting line will added to the existing facilities of Meishan Iron and Steel Company, to increase the cold rolling and hot rolling steel products by 2,300,000t/a, and corresponding systems and facilities for iron processing will also be built, so that the total steel output of Meishan Iron and Steel Company will reach 5,300,000t/a. (2) Necessity of project construction China is now in a rapid economic development period, with a large market for sheets for building purpose. These products mainly include zinc plated sheets, aluminum and zinc plated sheets, color coated sheets, hot rolling and cold rolling sheets. Especially, zinc plated sheets and cold rolling sheets of thin sizes are the steel products with the largest supply shortage, largest import and most outstanding supply to demand contradiction in China. Therefore, expanding the production of steel sheets is in line with the national interest. The product matrix adjustment and process equipment upgrading in Meishan Iron and Steel Company is the need of the strategic positioning of Baosteel Co., Ltd., and an important link for Baosteel to become one of the most competing iron and steel enterprises in the world. Baosteel is now among the world top 500, and it is striving to be one of the top three in the world in terms of comprehensive competing power among iron and steel producers by 2010. To realize this strategic goal and in conjunction with the strategic deployment of Baosteel Co., Ltd. to construct six major bases for fine and high quality products, Meishan Iron and Steel Company will be an important high quality sheets production base of Baosteel Co., Ltd. As the iron processing equipment in Meishan Iron and Steel Company is still at backward level and it can only making hot rolling products despite of its overall steel production scale of 3 million t/a, its product matrix is not quite rational, the profiting ability is not high, and the enterprise is still weak in market competing power and in resisting risks. Therefore, considering the market demand and the development of various units of Baosteel, the product development for Meishan Iron and Steel Company is focused on medium and high grade steel

for building purpose and silicon steel (for electrical purpose), especially, emphasis will be placed on the production of sheet materials in the professional and large scale production within Baosteel Co., Ltd., and the superiority of the thin slab continuous casting tandem rolling technology will be used to produce silicon steel, so that it can be complementary with other steel producing units of Baosteel, and also upgrade the comprehensive competing power of Meishan Iron and Steel Company. The output of existing cold rolling and galvanized sheets of Baosteel Co., Ltd. is limited, and after meeting the demand from automobiles and household electrical appliances and the base sheets for existing color coating units, the remaining products cannot meet the market demand for sheets for building purpose. The building industry is just the largest user for sheet materials. As the largest steel supplier in China, Baosteel Co., Ltd. has the conditions to bring into full play the superiority of the group, to organize the production to meet the market demand, while Meishan Iron and Steel Company has the ready conditions to undertake this mission. Adding a cold rolling mill in Meishan Iron and Steel Company aiming at steel for building purpose can further improve the professional division of work in the group and raise the comprehensive competing power of the group. The sustainable development of national economy needs cold rolling silicon steel, and presently in China, it is necessary to replace nearly 900,000t/a of hot rolling silicon steel with low cost cold rolling silicon steel. Sheet continuous casting technology will provide conditions to further lower the cost of raw materials for silicon steel. For the production of cold rolling silicon steel in Meishan Iron and Steel Company, the expanded sheet continuous casting machines can supply the raw materials, to reduce the production cost for silicon steel. The product matrix adjustment and process equipment upgrading in Meishan Iron and Steel Company is the need from industrial policies and the development of recycling economy. By bringing up the old with the new and the rational use of new technologies, new processes and new equipment, the overall energy consumption and production cost of Meishan Iron and Steel Company can be reduced, the production environment can be effectively controlled and improved, and the overall utilization rate of resources can reach a new level, so that the environmental quality and resident living quality in the surrounding area can be significantly improved, to achieve a harmonious win-win result for both the enterprise and the natural environment, realize concurrent improvement in social efficiency, economic efficiency and environmental efficiency, and to attain the goal of developing the recycling economy. (3) Favorable conditions for project construction There are complete front process conditions in Meishan Iron and Steel Company. The rough mill transformation is under way for the 1422mm hot rolling section, for supplying raw materials to the cold rolling plate plant of Baosteel Co., Ltd. The raw materials for wide sheets required in building market and silicon steel can be supplied by the sheet continuous casting tandem rolling mill under expansion. Therefore, the new cold rolling mill of Meishan Iron and Steel Company will have a steady and sufficient source of hot rolling raw material. Baosteel Co., Ltd. now has five high level cold rolling mills, and it has trained a large number of professional personnel for cold rolling mill construction, operation, management

and equipment maintenance, product development and marketing, which can ensure the smooth construction and operation of the cold rolling mill of Meishan Iron and Steel Company. Less land is required for the expansion of a cold rolling project by the existing 1422mm hot rolling mill of Meishan Iron and Steel Company. Meishan Iron and Steel Company has good capital supply conditions, hence sufficient capital guarantee can be provided for the construction of the cold rolling mill. Meishan Iron and Steel Company is located in East China and is affiliated to Baosteel Co., Ltd. Its equipment upgrading and product matrix adjustment is in line with the requirements in the latest “Development policies for iron and steel industry” of the state. 2.2 Environmental protection control and rectification plan to bring up the old with the new In Meishan Iron and Steel Company in 2004, the overall energy consumption per ton of steel was 0.82t std. coal, fresh water consumption 12.1m3/t steel, smoke and dust emission 3.56kg/t steel, and SO2 emission 6.2 kg/t steel. This shows that the environmental protection and energy consumption indicators are at a fairly backward level. Therefore, concurrent with the construction of the proposed project, it is necessary to implement technical transformation for the backward facilities of the whole plant in a way to bring up the old with the new, to substantially lower the energy consumption, water consumption and pollutant emission amount. The main measures are the following: (1) To realize the goal of fresh water consumption per ton of steel at 5m3 and to substantially cut the water pollutant emission, technical transformation will be implemented for the water systems of level II plants, to stop direct flow water systems as far as possible and replace them with recycling water systems; the recycling water systems with low recycling rate will also be transformed, to realize tandem discharge and raise the recycling rate. It is planned to build a new recycling water treatment facilities. It will be sized at 10×104m3/d. All waste water from production units and processing systems, and backwash water from the filtering tank in the water works will be recycled after treatment. The recycled water will mainly be used in the iron processing systems, as makeup water to circulating water systems and for cooling furnace slag and for spraying in raw materials yard. After the transformation, the fresh water consumption per ton of steel will be 4.7t/a, and the total fresh water consumption for both production and living purpose will be 4868m3/h, or 42,643,680 m3/a (including that for the co-gen power plant and Meishan Chemical Company). (2) It is planned to completely demolish the existing 3×65-duct coke ovens, which will be replaced by the new 2×55-duct large volume coke ovens, with coke output remaining unchanged. In the meantime, corresponding chemical product recovery unit and gas refined desulfurization facilities will be added, to basically eliminate the non-organized discharge from the coke oven, so that the hydrogen sulfide content in the coke oven gas will be less than 0.2g/m3, and the phenol and cyanogen containing waste water will be recycled after treatment without discharge. (3) At present, the co-gen plant of the Company has four 220t/h boilers, with one fired all by blast furnace gas, and the other three by mixed coal and blast furnace gas at 30%. Although 21

the raw coal only has a sulfur content of 0.4%, there is a SO2 discharge of 3190t per year. After the construction of the proposed sintering project, the total SO2 discharge of the Company will exceed the total amount control indicator (19000t/a) as specified by the environmental protection bureau. To effectively reduce the SO2 discharge of the Company, it has been planned to provide desulfurization devices for the three coal-fired boilers of the power plant. (4) The phenol and cyanogen waste water treatment station of Meishan Chemical will be transformed, and the A/O2 treatment process will be adopted, to treat all phenol and cyanogen containing waste water from the new and existing works, for a capacity of 300m3/h. The outflow water, as meeting the standard, will be recycled for slag sluicing for blast furnaces. (5) Overall control and rectification will be conducted for the blast furnace discharge yard, coking and sintering materials yard, raw materials yard, lime yard, slag yard, jetty and coal shed, by providing complete dust suppressing and removal facilities, adding fences, shed and hard pavement road, and providing water sprinkling facilities, so that the non-organized dust rising can be basically put under control. 2.3 Pollution factor analysis for the proposed coking project (1) Briefs of project Meishan Iron and Steel Company now has 3×65-duct coke ovens, producing 1,205,000t of coke in 2004. To meet the demand from increased steel output of 2,300,000t/a, it has been determined that the overall scale of the associated coking project will be 2,133,000t/a of dry complete coke, with 1 million t/a to be supplied to Shanghai No. 1 Steel Works. The coke ovens will be of 4×55-duct Model JN60-6 combination, and they will also be completed with the associated coal preparation, coke sieving, 2×140t/h dry coke quenching, gas refining and chemical products recovery units, as well as the corresponding auxiliary units and utility units. They will recover tar at 101,000t/a, sulfur at 4266t/a, ammonium sulfur at 24263t/a, crude benzene at 28440t/a, and gas at 910,1511 million m3/a. Investment in this Project is 1050.04 million yuan and the project will have a staff of 643 persons. Construction site is located at north part of the existing coking plant of Meishan Steel. (2) Process flow The process flow for coking production is as shown in Fig. 2-1. Coal preparation The coal preparation workshop is designed to store the incoming coal and process it into that meeting the requirements of coke oven production. The washed coal, after going through the coal receiving unit, is conveyed to the batching room for batching, and to the pulverizing room, and finally it is conveyed to the coal storage tower via a belt conveyor through the corridor and transit station, ready to be loaded into the coke ovens. ② Coking process The coal in the storage tower is loaded into the coking chambers by the dust removal and loading cart after metering, and the coal is distilled into coke in the coking chambers at high temperature, and raw gas is produced and collected at the top of the chambers. The raw gas enters the collecting pipe via the riser and bridging pipe, where it is cooled by ammonia water spray, and flows to the gas purifying workshop for further treatment. The gas for heating the coke oven and blast furnace gas is introduced by external pipes. 22

The waste gas produced during heating of coke ovens is discharged into the atmosphere via the stack.

Dry coke quenching process The ready-made coke in the coking chambers is pushed out by the pushing machine into the coke cart as guided by the coke guide. The coke cart loaded with red coke is towed by the electric locomotive to the bottom of the hoisting shaft of the dry coke quenching unit, and the hoist lifts the coke tanks to the top of the dry quenching oven, where the coke is loaded into the oven. In the dry quenching oven, direct heat exchange is conducted between the coke and inert gas. After cooling, the coke is discharged onto the belt conveyor, which conveys it to the sieving system. The inert gas is recycled after filtering and heat exchange. The dry coke quenching boiler produces steam through heat exchange, and the steam is used for power generation. The process flow of dry coke quenching is as shown in Fig. 2-2.

④ Gas purifying process The gas purifying section consists of the condensing and air blowing, desulfurization, ammonium sulfur, crude benzene, oil depot and associated auxiliary production facilities. The whole purifying process is performed by Meishan Chemical Company. a. Condensing and air blowing and electric trapping The raw gas from the coke ovens flows through the gas and liquid separator, transversal primary cooler, electric tar trapper, and is delivered to the desulfurization section after pressurizing by the blower. The condensate from the gas and liquid separator and transversal primary cooler is sent to the mechanical ammonia separating tank to separate the tar from ammonia, the tar is a finished product and ammonia will be recycled in use. Part of the ammonia water will be sent to the ammonia distilling column of the desulfurization section to extract concentrated ammonia, which will be used as desulfurizing agent. The deposited tar slag is removed by scrapers, and is delivered to the coal preparation system periodically to be mixed into the coal for coking. b. Desulfurization section This system consists of four parts: desulfurization and decyanizing, regeneration of desulfurization liquid, sulfur recovery and ammonia distilling with residual ammonia. The ammonia contained in the coke oven gas is used as the alkali source. Desulfurization is done with FRC process, to reduce the hydrogen sulfide content in gas to below 200mg /Nm3 and sulfuric acid is recovered. The gas from the intermediate naphthalene stripping unit enters the absorbing column, where the H2S and HCN is removed when it is sprayed with absorbing liquid, then it flows to the ammonium sulfur unit. The absorbing liquid from the bottom of the column is sent to the pre-mixing nozzle at the bottom of regenerating column, and then enters the regenerating column after mixing with air. The regenerated liquid flows via the foam separator in the middle of the column to remove the sulfur foam, and is pumped to the heat exchanger for cooling, before being sent back to the top of the absorbing column for recycling. The separated sulfur foam rises to the upper part of the regenerating column, and is discharged into the surging tank via the overflow port. The regenerated tail gas can be directly mixed into the gas pipe downstream the absorbing column. The suspended liquid in the surge tank is delivered to the super centrifugal machine for separation. The separated sulfur paste and filtrate flows respectively into the slurry tank and filtrate tank. The filtrate is pumped to the concentrating unit for concentration and then flows to the slurry tank to mix with the slurry, and the mixture is sent to the acid unit. The ammonia containing tail gas from the concentrating column is delivered to the gas absorbing pipe. Main features of FRC process: High efficiency to remove sulfur and cyanogens. High efficiency pre-mixing nozzles are used in the regenerating column, to reduce the amount of compressed air, the regenerated tail gas can be mixed directly into gas, eliminating

secondary pollution. The ammonia in the gas is used as the alkali source without additional alkali, to save operation cost. To avoid accumulated deposit from desulfurization liquid affecting the desulfurization effect, the discharged small amount of waste liquid is sent to the coal preparation section. c. Ammonium sulfur section The gas from the desulfurization section flows into the saturator via the gas preheater. In the upper part of the saturator, gas enters the ring chamber in two streams for spraying by the recycling master liquid, and the ammonia is absorbed by the sulfuric acid in the master liquid. Then the gas is combined into one stream to enter the rear chamber, where it goes through the last spray by master liquid, and enters the cyclone acid remover in the saturator, to separate off the acid mist carried by the gas. Finally it is sent to the light oil trapping device. The master liquid in the upper part of the lower section of saturator is pumped out continuously by the master liquid circulating pump to the ring chamber for spray. The recycling master liquid having absorbed ammonia flows via the central downcomer to the bottom of the lower section of saturator, where the crystal nucleus start to move upwards through the saturated medium, so that crystals grow and grains are sorted. The slurry liquid at the bottom is pumped to the crystallizing tank periodically. The master liquid overflowing from the saturator overflow port flows to the master tank via the liquid seal tank, and is then delivered by the minor master liquid pump to the rear chamber of the saturator for spray. In addition, the master liquid tank can also store master liquid when the saturator is serviced. The slurry liquid in the crystallizing tank is drained to the centrifugal machine, and the separated ammonium sulfur is conveyed to the vibrating fluidizing bed dryer, where it is dried by the heated air, and is then cooled by cold air, before flowing into the ammonium sulfur storage bucket. It is then weighed, packaged and delivered into the finished product store. The filtered master liquid and that overflowing from the crystallizing tank flow by gravity to the lower section of the saturator. The tail gas after drying the ammonium sulfur flows through the cyclone separator before being vented to the atmosphere by an induced draft fan. The ammonium sulfur is weighed and packaged semi-automatically, and is bagged and stacked manually. Main features: the spray type saturator is made of stainless steel, featuring a long service life, and integrating the pickling, acid removal and crystallization, the resistance across the gas system is low, the ammonium sulfur grains are big, with simple flow, advanced process and reliable technology. d. Crude benzene recovery section This system includes the process flows of end cooling, benzene stripping, nathphalene stripping and distillation of benzene containing rich oil to remove benzene. The gas, at 55~65 from the ammonium sulfur saturator, enters first the transversal gas end cooler and is cooled to 26~27 , and then it enters the benzene stripping column to contact in

counter flow with the lean oil at 29~30 sprayed from the top, so that the nathphalene and benzene in the gas are absorbed. The clean gas after benzene stripping will be partly supplied to the coke ovens and crude benzene tubular oven for heating in the plant, and the remaining will be conveyed to the gas storage and distribution station, where it is pressurized for supply to the outside. The rich oil having absorbed nathphalene and benzene flows into the rich oil tank at the bottom of the benzene stripping column, and is pumped to the crude benzene oil and gas condensing cooler and lean and rich oil heat exchanger, before being delivered into the tubular oven for heating. When heated to 180~190 , the rich oil enters the benzene removing column for distillation with superheated steam. The oil-gas escaping from the benzene removing column top enters the crude benzene oil and gas heat exchanger and condensing cooler, for heat exchange with rich oil and cold cooling water. The crude benzene obtained enters the oil and water separator, and the separated crude benzene flows into the reflux tank. This crude benzene will be partly delivered by the reflux pump to the top of the benzene removing column to control the quality of crude benzene product, and the remaining will flow from the top of the column to the crude benzene metering tank, pumped to the crude benzene tank by the product pump and periodically to the depot. e. Oil depot The oil depot stores the products of tar and crude benzene, and the raw materials tar stripping oil and concentrated sulfuric acid. The tar and crude benzene respectively from the condensing and blowing section and crude benzene section of the gas cleaning shop will be stored in the respective tanks, and then be pumped to the crude tar processing workshop of Meishan Chemical Company for further processing. (5) Emission of pollutants

The main pollutants from coking process are: smoke (powder) and dust, H2S, SO2, BaP and phenol and cyanogen containing waste water. The smoke (powder) and dust mainly come from the coal preparation system, coal loading during coking, leakage from oven doors, and from coke pushing and sieving; SO2 mainly comes from the combustion chambers of coke ovens; and coke breeze and water vapor from coke quenching; the waste water is the phenol and cyanogen containing waste water from the chemical systems; furthermore, the five major equipment and fans of the coke ovens will produce noise. The gas with coke breeze from the dry quenching oven loading port, discharge port, gas dispersed from the storage chamber and circulating gas fans will all be delivered to the ground dust collection station for dry coke quenching, and be discharged after removing the dust. The coke breeze separated from the primary and secondary dust collectors will be collected in the coke breeze tanks with special conveying equipment, for shipping out later on. The smoke and dust produced when coal is loaded into the coke oven is sucked into the dust collecting vehicle for coal loading, conveyed to the ground dust collection station via dust collecting duct, and is discharged to the atmosphere after dust removal. 27

The smoke and dust produced during coke oven discharge is sucked by the coke guide with dust hooks, conveyed to the ground dust collection station via dust collecting duct, and is discharged to the atmosphere after dust removal. During service of the dry coke quenching system, coke will be quenched with the standby wet method. The coke quenching tower is 45m high, with coke quenching water spray pipes at the bottom and baffled wooden strapping device at the top, so that it can trap the coke breeze and water drops produced during coke quenching, with a dust removal efficiency of over 70%. The phenol and cyanogen containing waste water produced during the desulfurization and refining of gas is treated by the coking waste water treatment station, and is all recycled for blast furnace slag sluicing and other purposes. 2.4 Pollutant prevention, treatment and control measures for coking project 2.4.1 Discharge of waste gas pollutants and control and rectification measures The fuel for heating and combusting in coke ovens is coke oven coke quenching (29773m3/h) and blast furnace gas (135220m3/h), and in addition, coke oven gas is also used in the tubular heating furnace for gas refining in Meishan Chemical Company. The main pollutants in the flue gas are SO2, NOX and small amount of smoke and dust. At present, coking plants in China usually use high stacks for discharge. In this project, high stacks will also be used, at a height of 125m. The pollutant discharge sources and control and rectification measures of the planned coking project are as shown in Table 2-1, and the discharge amount of pollutants are as shown in Tables 2-2 and 2-3. The main control and rectification measures for pollution sources are the following: (1) Coal dust from coal preparation system and control measures The coal preparation system includes the transport, batching, mixing, storage, pulverizing and belt conveying of coal. At all these points, in addition to water sprinkling to suppress dust and enclosed mechanical ventilation, enclosed air extraction is adopted at all dust producing points, and a mechanical dust collection system is provided. At all dust rising points at coal pulverizing room, such hooks are provided to prevent coal dust from escaping. High efficiency and low resistance Model DZW93 pulse bag filters have been selected to achieve a dust removal efficiency of 99.4%. The initial coal dust concentration will be 2000-5000mg/m3, and the dust concentration of the flue gas discharged after filtering will be about 30mg/m3. (2) Flue gas from coke oven loading and discharge and the control measures a) For coal loading, high pressure ammonia water will be ejected for the single gas duct, to form a negative pressure in the riser, to suck some smoke and dust into the gas duct. The remaining smoke and dust will be conveyed to the ground station via the flue gas suction and diverting mechanism of the coal loading and dust collecting vehicle, and the trunk dust collecting duct, so that the final discharge concentration of dust is less than 30mg/m3. To further improve the coal dust trapping effect, a small door sealing device is provided at the 28

coke pusher. b) Dust collection at coke discharge: it is realized by the ground station dust collecting system.

Dust collecting hoods are provided on the coke guide, to suck the flue gas produced at coke discharge via the hoods and trunk dust collecting duct to the ground station for cleaning and then discharge. c) Automatic venting and ignition device: This device is provided at the vent pipe, to burn up the lean gas dispersed from the collecting duct. The ground dust collection station system for coal loading and coke discharge is as shown in Fig. 2-3. (3) Smoke and dust control measures for coking a) Spherical sealing is adopted for the coal loading port cover, to increase the seal-tightness of this cover with its base through spherical contact. b) Elastic edge is adopted for the oven door, loaded with springs, so that the edge is subjected to homogeneous force for good sealing effect. c) Water seal structure is adopted for the riser cover and bridge pipe and valve socket on the top of the oven, to prevent smoke escaping from the riser cover and bridge pipe socket. d) The riser root is provided with a cast iron base, sealed with woven asbestos filled with slurry, to avoid smoke and flame escaping after damage of the riser root. (4) Flue gas from dry coke quenching and its dust collecting system After the high temperature flue gas from the coke tank top and circulating fan port is first trapped by the suction hoods, it is first cooled by a cooler and then mixed with the cool air with dust from the coke discharge port and the belt conveyor and the fresh coke transit station. The temperature of the mixed gas will be below 110 . It then enters the 24000m2 pulse bag dust collector for cleaning, with system air flow at 130000m3/h, dust removal efficiency at 99.7%, and discharge concentration 30mg/m3. The cleaned gas is discharged into the atmosphere via fans and silencers. The filtering element of dust collector is made of anti-electrostatic materials. The dust collected by the collector is put together with that from the primary and secondary process collectors, and is sent to the dust silo by the bucket lift. Then, it is moistened by the humidifier for periodical shipping out by dedicated vehicles. The process flow is as shown in Fig. 2-4. The wet coke quenching tower serves as a backup quenching facility. During quenching, steam containing dust and volatile pollutants will produce from the top of the tower. As a control measure, a demisting device and grid (or shutter) type baffle dampers are provided at the top of the tower as dust removal devices, with a cleaning efficiency better than 70%.

(5) Dust collection for coke sieving and coke store in front of oven Dust in this system is produced mainly from belt conveyor stations, coke tanks, vibrating feeders, coke store in front of oven, and vehicle transit points. As the equipment does not operate all at the same time, motor-driven valves are provided on the duct over each suction

hood, to reduce energy consumption. The dust-bearing gas collected by the hoods enters the 50000m2 pulse bag dust collector, before being discharged outdoor via fans and silencers. The system has a air flow of 210000m3/h and the discharge concentration 30mg/m2. The collected dust is put together by the scraper and sent to the dust silo by the bucket lift. Then, it is moistened by the humidifier for periodical shipping out by dedicated vehicles. The process flow is as shown in Fig. 2-5. (6) Waste gas sources from gas cleaning and chemical product recovery, and the control measures Waste gas from gas cleaning and chemical product recovery systems mainly consists of volatile pollutants produced from: condensing and blowing section, desulfurization section, ammonium sulfur section, crude benzene section and the main associated facilities such as clarification tank, storage tank and cool water frame. The main control measures are: a) Waste gas control measures for condensing and blowing section ·The tar slag separated from the mechanical ammonia water clarification tank is received by a dedicated slag box and sent periodically to the coal preparation system, for mixing into the coking coal, to prevent secondary pollution. ·Low noise conveying equipment will be selected, and measures to reduce noise level will be adopted for relevant buildings. ·An accident ammonia water tank will be provided, so that waste water from the circulating ammonia water system will not be directly discharged during a short production accident.

· The crude benzene product will be stored in an inner floating roof tank, to reduce volatility of crude benzene and improve the production environment. d) Waste gas control measures for oil depot section · The crude benzene tank will be of inner floating roof structure, to reduce volatility of crude benzene and improve the production environment. · The top of the concentrated sulfuric acid tank will be provided with a moisture removing device, to prevent dilution of concentrated sulfuric acid by absorbing water, to corrode equipment and prevent the gas from polluting the environment. · A breathing valve will be provided at the top of the tar storage tank, to reduce the emission of harmful gas. · The design will be based on the geographic location of the site and actual conditions, to ensure storage capacity for raw materials and products, and vehicle loading and unloading facilities will be designed accordingly. The storage period for tar, crude benzene, tar stripping oil and concentrated sulfuric acid will all be 15-20 days. (7) Non-organized discharge sources in the coking plant and control measures The pollutant discharge and control level of mechanical coke ovens in China In drafting the “Discharge standard of atmospheric pollutants from coke ovens”, the Environmental Science Academy of China conducted massive survey and investigation on the particles, BSO and BaP produced during coking for different levels of coke ovens in key coking and chemical enterprises of China. The classified statistic results of the monitored data are as given in Table 2-4. It can be seen from this table that the pollutant discharge level from coke ovens differs greatly among different types of coke ovens and for different management levels. Table 2-4 Overall and classified pollution control level for mechanical coke ovens in China

Non-organized discharge and control measures for the project a) The facilities in the coal yard will be reformed with the rebuilding of the existing

3×65-duct coke ovens, and all 6×55-duct coke ovens will share a common coal preparation system, so that the non-organized dust rising from the coal yard will be put under control fundamentally. The coal conveying station, pulverizer room and conveying corridors will all be enclosed structures to prevent pollution by the escaping coal dust, the refined coal yard is fully enclosed and water spray facilities are designed at main dust rising locations to suppress dust to prevent secondary dust rising. The coke conveying system is provided with an enclosed corridor to prevent escaping of coke breeze. At main dust rising places, ground flushing and water spray facilities are provided to reduce dust and prevent secondary dust rising. b) The raw gas escaping during coal loading into the coke ovens and the non-organized raw gas escaping from the oven doors and top during coking contains dust, SO2, BaP, CO and NOn. In this project, coal will be loaded with high pressure ammonia water spray, and ground dust collecting stations will be provided to control the smoke and dust during coal loading and coke discharge, therefore basically no smoke will produce during coal loading operation. c) The waste gas discharged from the coke oven body during coking contains dust, SO2, BaP, CO and NOn. With the negative pressure operation of the gas collecting pipes at -3bar or -300Pa, raw gas escaping during coal loading into the coke ovens and the non-organized raw gas escaping from the oven doors and top can be effectively controlled; the pressure of each coking chamber is adjusted separately, to ensure no smoke will escape from the oven door and coal loading port, so no smoke will produce in coke production. d) The flue gas discharged during coke discharge contains dust, H2S, BaP, SO2, NH3, CO and NOn. The horizontal coke discharge process is designed to reduce smoke and dust emission, and a ground station shared with the coal loading is used to collect dust. After dust removal, the dust concentration in the discharged flue gas will be about 30mg/m3. Investigation and analysis for comparison a) Monitoring result of BaP in the ambient air of the coking plant of Jiuquan Iron and Steel Company and its surrounding area At Jiuquan Iron and Steel Company three monitoring measurements were conducted during the 1980s for the BaP in the ambient air of the coke ovens and the surrounding area, and the monitoring results are as shown in Table 2-5. It can be seen from the table that the BaP in the ambient air during the monitoring period exceeded the standard. The BaP of the waste gas discharged from coke ovens 1# and 2# all exceeded the standard. During Nov. 28 to 30, 2000, we performed site measurement again for the particles, BSO and BaP in the non-organized waste gas discharged from the existing 1#, 2#, 3# coke ovens of Jiuquan Iron and Steel Company during their production, as shown in Table 2-6. There have been fundamental changes as compared with the monitoring results of the 1980s, and the non-organized discharge basically meet the standard. This indicates that technological progress and control with environmental protection actions have achieved good effect in

reducing pollutant discharge during coking process. Table 2-5 BaP testing results for coke oven and ambient air in Jiuquan Iron and Steel

Table 2-7 BaP monitoring results for coke oven top in Taiyuan Iron and Steel Company Unit: µg/m3 Grade II Item 4# 5# 6# standard value Concentration range 0.1-7.2 0.29-13.63 0.39-1.77 (µg/m3) 4 No. of samples 14 8 8 Average value 2.06 2.63 1.01 c) Pollutant discharge analysis for coke ovens of this project For this project, Model JN60-6 combination coke oven will be selected, which is advanced in process level and mature in technology. It is an advanced model in China, featuring short coal charging time, concentrated flue gas for easy collection, and good seal-tightness of oven door, therefore the amount of non-organized discharge will be small. By comparing with the monitoring results in Tables 2-6 and 2-7, it can be concluded that the non-organized discharge of waste gas from the coke ovens of this project can meet the grade II standard requirements in Table 2 of the “Atmospheric pollutant emission standard for coke ovens” (GB16171-1996), i.e. particles at 2.5mg/m3, BSO at 0.60mg/m3 and BaP at 0.0025mg/m3. The design institute shall take these into full consideration, so that the pollutants in the waste gas of non-organized from the coke ovens meet the “Atmospheric pollutant emission standard for coke ovens”. In the meantime, the amount of BaP will be controlled below 1.0 g/t coke (in the clean production standard for coking industry (HJ/T126-2003), the BaP limit values are ≤1.0g/t coke for grade I and ≤1.5g/t coke for grade II for coal loading). According to the source intensity monitoring on large and new type coke ovens by the Environmental Science Academy of Shanxi Province and others, the discharge source intensity of BaP from coke ovens is 36mg/t coke. For this project, it is taken as 50mg/ mg/t, so the annual BaP discharge amount from coke ovens will be 106.71kg. 2.4.2 Waste water pollutant discharge and control and rectification measures (1) All refining of coke oven gas in Meishan Iron and Steel Company will be performed by Meishan Chemical Company. For the production and discharge of relevant pollutant, refer to the section for gas refining.

(2) Water supply and drainage for coking and pollutant discharge The total water consumption for the planned coking project (4×55 ducts) will be 1027 m3/h, including 100m3/h (for steam production in the dry coke quenching boiler) as demineralized water, reflux water of 166.7 m3/h, and circulating water flow at 10000 m3/h, with water circulating rate of 97.4%. The production waste water discharged will be 106.7 m3/h, mainly as equipment cooling water. The water supply and drainage balance is as shown in Fig. 2-6.

3. Feasibility analysis and technical and economic demonstration

of environmental protection measures

The feasibility of environmental protection measures is a matter concerning not only the resource utilization of an enterprise and the environmental impact of its pollution discharge but also its economic benefit. The adoption of practical “three wastes” control measures is a prerequisite for an enterprise’s implementation of sustainable development. Principally in line with relevant requirements on pollutant discharge standards, control of total amount and the principle of up-to-standard discharge of pollutants, this chapter analyzes the technical and economic feasibility of the environmental protection measures of this construction project and provides corrective actions to address possible problems. During production of this project, the main “three wastes” discharged are waste gas and wastewater. Therefore, this chapter mainly analyzes and appraises the environmental protection measures for waste gas and wastewater and only gives general analysis on slag and noise. 3.1 Overview of environmental protection measures for existing projects 3.1.1 Existing waste gas pollution control measures The existing waste gas pollution control measures in Meishan Iron and Steel Company (including Meishan Chemical Branch) are shown in Table 3-1. From Table 3-1, we can see that both Meishan Iron and Steel Company and Meishan Chemical Branch have adopted effective measures to control waste gas pollutants, waste gas pollutants are emitted after reaching standard and all waste gas control facilities have passed the “three simultaneouses” completion acceptance.

washing wastewater and tar raw material separating water. The above industrial wastewater enters the phenol-cyanogen sewage treatment station of Meishan Chemical Branch where it is treated and discharged into North Discharge Outlet. COD and NH3-N are not up to standard. (2) In existing projects, only 63% of coke oven gas is desulfurized. The desulfurization ratio is low. The amount of SO2 emitted from gas combustion is 2534t/a. (3) In Meishan Iron and Steel Company, the water consumption per ton of steel is high ((12.1t/t of steel) and water reutilization rate is low (92.6%). (4) Meishan Chemical Branch consumes a large amount of equipment cooling water, which is directly supplied with fresh water, causing much waste. (5) The existing three coke ovens were built in early 1970s and mid 1990s and are rundown with serious pollution of fugitively emitted smoke gas and other harmful gas. (6) The fugitive emission of dust at places like BF cast house, coke oven, stock house and slag yard is serious. The total emission reaches 6965t/a, accounting for 65% of the total emission of Meishan Iron and Steel Company. 3.2 Analysis of pollution prevention and control measures for intended project and countermeasures 3.2.1 Prevention and control measures of key waste gas pollution sources and feasibility analysis The waste gas emission sources in this project mainly include: smoke gas from coal charging during coking, flue gas from heads and tails of sintering machines, flue gas from BF cast house, flue gas from converter, flue gas from converter auxiliary system, flue gas from LF, dust from stock house, bulk material system, belt conveyance and other nodes, and a small amount of organic waste gas generated during chemical product processing. The main control measures adopted are described in Table 3-5. From Table 3-5, it can be seen that this project adopts nationally common practical and effective measures to control main waste gas pollution sources and ensure pollutants are discharged only after reaching emission standard. The measures are feasible. In an iron & steel company, coke plant, sintering plant, ironmaking plant, steelmaking plant and cold rolling mill are main contributors to pollution. Below is further feasibility demonstration on the environmental protection measures controlling the following key pollution sources: coal charging and coke discharging of coke ovens, dust removal at heads and tails of sintering machines, purification of BF gas, converter gas, and control of acid mist from cold rolling. (1) Analysis of dust removing measures for coking facility a. Coal preparation workshop In this project, a pulse bag filter is installed in coal pulverizer room. The dust collection efficiency exceeds 99.4%. The dust concentration and emission rate at the outlet of the exhaust tube are both up to Grade 2 standard for new projects as defined in the Integrated Emission Standard of Air Pollutants and the Emission Standard of Air Pollutants for Industrial Kiln and Furnace. About 1550t/a of emitted coal dust can be mitigated, showing 38

obvious environmental benefit. In the new coking projects or technical innovation projects in China, the coal pulverizer rooms of coal preparation workshops all adopt this dust collection method. This method is characterized by low investment, good effect, stable and reliable operation and high operability. In addition, this project adopts closed coal transfer tower, vestibule of coal belt conveyor and other dust suppression measures. b. Dust collection during coal charging and coke discharging and emission control of waste gas from coke oven proper Coke oven proper is one of the key pollution sources in the intended project. The air pollutants emitted from it cause big harm. This project adopts JN60 6m coke oven, which is the largest in China and adopts advanced process equipment and environmental protection facilities to minimize the emission of air pollutants from coke oven from the approach of process. Meanwhile, the project adopts advanced process equipment and environmental protection equipment: a series of general control measures are adopted, such as: adopting new-type sealing structure for coal charge lid of coke oven, water seal device for coke oven uptake lid and bridge pipeline spigot joint, plugging woven asbestos rope to uptake root, and injecting high pressure ammonia during coal charging. They are economical, practical, feasible and reliable technologies. These pollution control measures are widely adopted by coke ovens at home and abroad. It is proved that theses measures can effectively prevent leakage of coke oven proper and reduce smoke gas emission of coke oven proper by 90%-95%. In addition, this project also installs nationally, even internationally advanced dust collecting ground station system for coal charging and coke discharging in coke oven, realizing more than 95% of smoke gas collection rate and 99.7% of dust collection efficiency and effectively controlling air pollution of coke oven. It is one of the best methods at present to solve air pollution generated from coke oven during coal charging and coke discharging. In order to more easily analyze through comparison the advancement, reliability and feasibility of smoke gas control technology for coke oven during coal charging and coke pushing in this project, we list the general condition of the coke oven coal charging smoke gas control technologies adopted in China and foreign countries in Table 3-6 and that of the coke oven coke discharging smoke gas control technologies in Table 3-7.

In this project, non-combustion dry-type dust collecting ground station is used to purify and treat the smoke gas generated from coke oven during coal charging. The smoke gas collection rate exceeds 95%. This technology has been widely used in large coke ovens in China since Baosteel Phase-3 Project. Certain operation experience has been accumulated. It has obvious pollution control effect. The practice has proved the technology is mature and features stable and reliable operation and good effect. In this project, dust collecting ground station with flap docking valve is used to control smoke gas generated from coke pushing. After trapped by movable dust hood and the combined dust hood on coke guiding car, smoke gas is sent to dust collecting ground station to remove dust. The dust collecting ground station system for coke pushing of coke oven is an advanced technology controlling smoke gas generated from coke oven during coke pushing in the world. It is used in most coke plants in China at present and is one of the optimal methods solving pollution generated from coke oven during coke pushing. By adopting a series of pollution control measures for coke oven, the total amount of pollutants emitted from coke oven is cut by about 90% on average. c. Coke quenching system The intended project adopts CDQ (coke dry quenching). CWQ (coke wet quenching) is reserved. CDQ process can not only greatly reduce the emission of coke dust but also recover sensible heat of coke and generate steam. It is the development direction of coke quenching process in coking industry. In order to reduce dust emission during CDQ, dust traps are installed at coke charging point at the top of CDQ boiler, at coke discharging point in bin bottom, over the belt at coke outlet, at the bleeding outlet of circulating fan and other places to collect and send the dust to CDQ dust collecting ground station. In the station, large pulse bag filter is used to collect dust. This technology has been used in Baosteel, Jinan Iron & Steel Corporation and Shanghai Pudong Gas Plant for some years. Certain operation experience has been accumulated. Practice has proved this process and its equipment feature stable and reliable operation and obvious dust collection effect. The CWQ tower as standby is installed with baffle-style wood-grid dust trap at tower top. It can trap the coke dust generated during CWQ. The coke dust collection rate is 60%. The dust emission concentration and rate at tower top outlet are both up to Grade 2 standard as defined in the Integrated Emission Standard of Air Pollutants. This technology has been widely used as standby equipment for CDQ. d. Coke sieving and storage system The coke sieving and storage system is provided with a bag type dust collector with dust collection efficiency of above 99%. Bag type dust collector has desirable dust collection effect and stable and reliable operation. Mature operation experience has been achieved in China. The coke dust concentration and emission rate at the outlet of the dust collector both can steadily reach respective emission standard. In addition, the main dust generating points in coke sieving and storage system and coke

transfer vestibule are designed in a confined way to prevent fugitive emission of coke dust. e. Synchronous upgrading of existing coke ovens

The current coke oven facilities of Meishan Iron and Steel Company are backward. The fugitive emission of smoke gas reaches 4425t/a, SO2 412t/a and other harmful gas serious. Synchronously with the construction of this project, the current 3×65-duct coke ovens will be upgraded. They will adopt the process facilities and environmental protection measures same as those adopted by the intended coke ovens, thus basically bringing the fugitive emission from coke ovens under control and greatly improving the environment of the plant area. (2) Control measures for flue gas generated from heads and tails of sintering machines At present, the development of sinter dust collection technologies in China can be summed up into the following aspects: ◇ Universally adopt high-performance dust collectors, mainly including electro-precipitator and bag type dust collector; ◇ Combine large centralized dust collection system with decentralized dust collection; In recent years, Chinese and foreign sintering plants tend to use large centralized dust collection system. A dust collector usually contains tens or hundreds of dust collection points. Furthermore, such dust collection method is often combined with decentralized dust collection and separate dust collectors are installed for dust sources which are too far to be included into the large dust collection system. ◇ Priority is given to dry type dust collection in order to avoid sewage and sludge problems brought by wet type dust collection; ◇ Realize computerized control to raise equipment’s control capacity and ensure dust collection equipment runs in an optimized state. a. Flue gas control at the heads of sintering machines The amount of dust generated at the heads of sintering machine has a relation with such factors as sintering process, the characteristics of agglomerated charge, and sinter operating state. The intended 380m2 sintering machine adopts clean production process, such as: micropellet sintering and deep-bed operation. Such approaches will significantly reduce dust content of sinter waste gas and the concentration of smoke gas won’t exceed 2.5g/m3 in general. At machine head, 250m2 electrostatic precipitator is used. Its dust collection efficiency is above 99.5% and dust emission concentration is lower than 40 mg/m3, so it is rest assured that the pollutants emitted can steadily reach emission standard. b. Dust control at machine tail The initial dust concentration at machine tail is 5g/m3-15g/m3 in general. Electro precipitator with dust collection efficiency of above 99.5% is used. The dust emission concentration is lower than 40 mg/m3, steadily reaching emission standard. However, it is noteworthy that this is a large centralized dust collection system, so how to raise dust collection rate is an issue to which the design must give sufficient attention:

a) During design, importance shall be attached to the balance of resistance in each branch pipe and the adjustment of air volume, thus guaranteeing the dust collection efficiency of each dust source. b) Curve bends and tee pipes shall avoid orthogonal connection. The curvature of pipe bends should be as big as possible to reduce resistance loss and pipeline wear. c) Attention shall be paid to the design of dust hood. Although the structure of dust hood is simple, it has a direct bearing on the confinement of dust source and the effective use of air volume. A reasonably designed dust hood can generate double effect, as it not only confines dust source but also saves a great amount of energy. c. Dust control of the sieving and size stabilizing system for finished products The initial dust concentration in this system is usually lower than 5g/m3. According to design, an electro precipitator with dust collection efficiency of above 99.5% will be installed. The dust emission concentration is lower than 40mg/m3, lower than the emission limit 120mg/m3, steadily reaching emission standard. In conclusion, the intended sintering facility adopts high-performance dust collection facility to control smoke gas and uses large-scale centralized dust collection method. The dust collection design is advanced and reliable. Meanwhile, the assessment also points out the issues to which attention needs to be paid during design and management. Design and construction units are requested to attach importance to them. d. Pollution control of flue gas SO2 generated in machine heads and analysis of steady standard attainment

At present, there are three measures to control SO2 generated from sintering in China by and large: firstly, control sulfur content of raw and fuel material; secondly, adopt a high chimney to disperse and dilute it; thirdly, desulfurize sinter flue gas. The desulfurization installation needs a considerable amount of investment, accounting for above 30% of total investment of a project. What is more, its operation cost is high and the recovered byproducts usually don’t have a good way to use. The industrially advanced countries in Europe and America currently mostly adopt the method of dispersion by high chimney. In China, there still isn’t any practice about desulfurization of sinter flue gas. This intended 380 m2 sintering machine is not provided with flue gas desulfurization measure, but a space for flue gas desulfurization is reserved. It is believed this approach is feasible in light of China’s current situation, because: a) Sinter flue gas features large amount and low SO2 concentration. No economical and practical desulfurization method is available for the time being. b) The ore owned by Meishan Iron and Steel Company has high sulfur content, but the intended project will mostly use imported ore. In order to further reduce SO2 emission, it is planned to use 1.40 million tons of ore owned by Meishan Iron and Steel Company to reduce the average sulfur content in ore to 0.09459%. The sulfur content is in an average level compared to Chinese large sinter plants. The emission concentration of SO2 in flue gas is

726mg/m3, steadily reaching emission standard. Meanwhile, in order to control total amount of emission, the flue gas from power plant is desulfurized to partially reduce the increase of

SO2 from increased sinter. When the condition is ripe, desulfurization of sinter flue gas will be adopted. At present, Taiyuan Iron & Steel Corporation is carrying out initial preparatory work for sinter flue gas desulfurization project. (3) Analysis of dust collection measures for 3200m3 BF a. Dust collection of cast house Most of the large and medium blast furnaces built in recent decades have cast house dust collection facility. Except Wuhan Iron & Steel Corporation, other iron and steel companies all have adopted bag type dust collectors. In addition, with respect to the concentration of smoke gas at dust collector outlet, they all realize up-to-standard emission. This indicates China has no technical problem in the design and manufacture of cast house dust collection facility. The intended 3200m3 BF cast house has a set of long bag low pressure pulse bag filters. They work together with BF secondary flue gas dust collection system to collect dust. The dust collection efficiency: ＞99.0%. The filter material is membrane needle punched felt (24 chambers). According to Baosteel experience, the mode of induced draft from tap hole confined chamber is adopted, a hood is installed below tuyere platform, part of the platform is made into a movable platform and the hood and the movable platform are joined together. During normal tapping, the movable platform is slanted. During overhaul of tuyere, the movable platform is put down. In order to raise trap effect and prevent leakage of a small amount of flue gas, apron is installed around the hood. The area of the apron is about twice as much as that of the hood. In conclusion, this project borrows the experience of Baosteel. In addition, the filter material is membrane needle punched felt (24 chambers) characterized by damp resistance, easy dust removal and high efficiency. Provided the equipment is properly maintained and managed, emission standard can be steadily reached. b. Dust collection of raw and fuel material system The large and medium BF built or extended in recent years all adopt confined dust collection facilities for dust sources of raw and fuel material system and universally adopt bag type dust collectors. The dust collection design of raw and fuel material system in this project has two features: Firstly, the dust collectors of the raw and fuel material system are arranged by location and a mode combining large-scale centralized dust collection and decentralized dust collection is adopted. For example, the feeding system and transfer tower system have five sets of dust collection equipment in total and adopt decentralized layout. BF ore and coke bin, and railway stock bin have a large-scale dust collector and adopt large-scale centralized dust collection mode. In this way, the advantage of large-scale dust collection is fully played and meanwhile insufficient draft at far area and pipeline blockage due to too large coverage of dust collection

pipeline is avoided. Secondly, ore and coke bins are the biggest dust sources of this system. There are 15 bins in total. Discharging cars need to move between bins. The design adopts fixed-point discharging for the discharging cars and the dust collection method of bin top induced draft under the support of sealing rubber belt. The dust suction tube in the upper part of each bin has an electric shutoff valve. The opening and closure of the valve is interlocked with the discharge action of the discharging cars. When the car is discharging material at a bin, this electric valve corresponding to this bin will be switched on to suck wind, while other electric valves are closed to enhance the air suction effect of the bin where material is being discharged to reduce overall wind consumption of the system. This method has been universally applied in China and achieved good effect. It can not only effectively control dust dispersion but also obviously reduce wind consumption of dust collection, and energy consumption. Therefore, it is feasible that this project universally adopts bag type dust collectors in raw material dust collection system. Years’ experience has been accumulated in China and can be used as reference. It is a mature and reliable technology and can steadily reach emission standard. c. BF gas purification BF gas purification technologies can be classified into wet type purification technology and dry type purification technology. The dry type usually adopts bag type dust collector. It avoids the trouble of treating gas cleaning water, has small investment and low operation cost. It has been used in small blast furnaces since 1970s. At present, large blast furnaces still widely adopt wet type purification method. At present, there are three types of BF gas wet type purification process in the world: a) BF gas→gravity dust collector→washer→venturi→clean BF gas→Users b) BF gas→gravity dust collector→venturi→venturi→clean BF gas→Users c) BF gas→gravity dust collector→Bischoff scrubber→clean BF gas→Users Type a) is a comparatively backward process and universally adopted by normal-pressure BF. The large blast furnaces built in China in early period all adopt this process. The largest blast furnaces newly built in China and foreign countries no longer use it. The dust content in the gas purified by this system is lower than 10mg/m3 and can fully meet production requirement. However, it occupies large floor space, needs large investment in engineering construction and consumes much water (5~5.5kg/m3) and power. Type b) process has the following advantages: occupy a small floor space, save more than 60% of investment, and have small water consumption (2.1~2.2kg/m3). It is suitable for BF operated under high pressure. The large blast furnaces built in recent years in China almost all adopt this process, for example: 10＃ and 11＃BF of Anshan Iron & Steel Corporation, and 1＃, 2＃ and 3＃ BF of Baosteel. Its shortcomings: the first venturi is seriously worn and its throat and passage wall have to be replaced or mended about two years later. The life span is short. The key equipment of Type c) process is Bischoff scrubber which is a patented product of

German Bischoff Company. This system was firstly applied in West Europe and introduced into China in recent years. Kunming Iron & Steel Corporation is the first user. New 1# and 2# BFs of Anshan Iron & Steel Corporation also adopt this system. It is proved by production practice that Bischoff annular gap scrubber has an even flow field, can ensure gas dust collection quality even with a small pressure difference, and has a large adjustable range of pressure difference, small erosion wear and long use life. Moreover, the water consumption of gas cleaning is about 2.0kg/m3, equivalent to that of double venturi system. To summarize, the BF gas purification method adopted by this project: gravity dust collector+Bischoff scrubber is an advanced treatment method at present. (4) Dust collection measures for 150t converter and its refining furnace a. Control measures for primary converter flue gas This project adopts generation-4 OG system, i.e.: “annular gap (RSW) adjustable venturi new technology to purify primary converter flue gas. This technology has the following features: the flow cross-sectional area at throat has a large adjustment range, the adjustment is linear, and the flow cross-sectional area at venturi throat can be adjusted through a hydraulic servo device no matter how the flow of flue gas fluctuates or changes. As a result, little smoke comes out of converter throat opening, no much air is sucked into it, thus ensuring and strengthening the treatment effect of double venturi and raising gas recovery rate and dust collection efficiency. Comparing with original R-D throat in China, RSW has wider adjustment range. Under same resistance, the throat and water orifice are not easily blocked by lime, increasing the operation stability of the second venturi and obtaining higher dust collection efficiency than RD’s. This system is characterized by concise process, less equipment, easy maintenance, water and electricity saving, and good purification and recovery effect. The dust content in the recovered gas is ≤10mg/m3. 90m3/t steel of gas is recovered. The scale of the equipment is set at 100t converter. b. Control measures for secondary converter flue gas The secondary converter flue gas includes the flue gas generated from converter hot metal charging and blowing and the cutting of steel bound to throat, the smoke gas generated from inside the furnace during repair, the smoke gas generated during cutting with oxygen lance and the flue gas generated during conveyance and feeding of ferrous alloy. Secondary flue gas adopts large positive pressure reverse blow deashing large bag filter. Pulse deashing bag filter features high filtration speed, light equipment, small investment, small floor space, high deashing capacity, high dust collection efficiency, stable and reliable operation, and high assurance to steady attainment of emission standard. c. Control of flue gas generated from molten iron pretreatment Flue gas generated from molten iron pretreatment includes mixer flue gas, flue gas from external molten iron refining and so on. See Fig. 3-1. The flue gas from molten iron pretreatment adopts positive pressure reverse blow deashing large bag filter. Multiple dust suction points are arranged. The total air output is 600000m3/h. Dust collection efficiency exceeds 99.4%. The dust concentration in emitted flue gas is 30mg/m3. The flue gas is emitted

via a 40m chimney, meeting Grade-2 standard as defined in the Emission Standard of Air Pollutants for Industrial Kiln and Furnace (GB9078-1996) and basically guaranteeing no fugitive emission of smoke gas from converter workshop. (5) Dust collection measures for new thin-slab continuous casting and rolling machine a. When receiving protective slag, CCM crystallizer will generate a small amount of dust-containing flue gas. The flue gas is led by fan into continuous casting secondary cooling chamber where it is purified by vast water fog and then emitted via a 30m exhaust tube, meeting Grade-2 standard as defined in the Integrated Emission Standard of Air Pollutants. b. The instantaneous dust generated from unpacking and tipping of tundish is controlled by method of dust suppression through locally spraying water. c. Roller hearth-type heating furnace consists of heating section, common section and transverse movement section. The flue gas from combustion in heating section and common section is emitted via three 60m chimneys. The flue gas generated from transverse movement section is emitted via furnace top chimney. As desulfurized mixed gas is used, the emission concentration of SO2 is low. d. Finishing mill generates a small amount of flue gas that contains ferric oxide during rolling. Sinter-plate dust collector is installed. Its action principle is similar to bag type dust collector’s, but it has better deashing effect than the bag type dust collector. The dust concentration can be controlled below 20mg/m3. The stainless steel CCM of Taiyuan Iron & Steel Corporation adopts sinter-plate dust collector. Its dust emission concentration is below 10mg/m3 and the equipment is wear and corrosion resistant. Therefore, sinter-plate dust collection system has a lower possibility of accidental emission comparing with bag type dust collector.

Large bag filter Large exhaust Overflow exhaust hood of Exhaust hood in fan torpedo car desulfurization chamber of torpedo car Fig. 3-1 Coke gas dust collection system for molten iron pretreatment e. Baking and heating for continuous casting, and annealing furnace use clean gas as fuel, so

SO2 concentration in fugitive flue gas is not high. The emission of air pollutants from continuous casting facility is characterized by more sources of fugitive emission. This construction project is not an exception. The design adopts control measures to address the

characteristics of each pollution source. The steady attainment of emission standard can be realized by and large. f. The maintenance of tundish is an important step for continuous casting production. It is discontinuous and can be classified into light repair, medium repair, general overhaul and all repair. In this project, water spray is adopted to remove dust during tundish dismantlement and maintenance. No dust collection device is used. In view of pollution control in continuous casting process of Baosteel and the steelmaking plant of Benxi Iron & Steel Corporation, they all install dust collection facility for tundish maintenance to improve work environment. The popular dust collection facility in China is shrinking bellow-type sealing hood installed in the upper part of the slope platform and suction tube installed in the lower part of the lining removing platform. The dusty gas is emitted to the atmosphere after passing through bag type dust collector. Simply adopting spray method to settling dust may affect the progress and quality of repair, so it is suggested to reserve a space for dust collection facility. (6) Smoke gas control measures for cold rolling facility a. The ferric oxide-containing dust generated by welding unit and tension leveler adopts pulse bag filters. The air volume of the system is 72000m3/h and the dust emission concentration is lower than 30mg/m3. b. The acid washing and continuous rolling unit generates HCl mist and H2SO4 mist. Silicon coating unit generates chromic acid mist. 3 The initial emission concentration of acid mist is about 600mg/m ; meanwhile, NOx gas is generated, too. A cover is designed to seal each acid tank. An air suction system is installed to ensure the tank is under negative pressure. The acid mist sucked out is sent to purifying tower for treatment. HCl and chromic acids enter different washers for washing. Mixed acid mist is washed and neutralized by alkaline water and then the gas will be led to SCR treatment unit in which atomized KMnO4 and sodium thiosulfate are sprayed to convert NOx into “ammonia and water vapor”. The treatment efficiency is higher than 90%. The purified gas is emitted to the atmosphere via a chimney. The concentration of each kind of the main pollutants in the 3 3 3 purified gas is: HCl mist≤10mg/m , chromic acid mist≤0.07mg/m , NOx≤50mg/m , H2SO4 mist≤10 mg/m3, meeting Grade 2 standard as defined in the Integrated Emission Standard of Air Pollutants GB16297-1996. c. Rolling machine and finishing line generate oil mist. In order to avoid fugitive emission of oil mist in the workshop, it is designed that the oil mist is trapped by gas trap and smoke exhaust hood, purified by filter (purification rate is 90%), and finally emitted to outside of the workshop. The concentration of oil mist emitted to the outside is lower than 20mg/m3. The waste oil obtained from the filter is recycled by finishing unit. d. The degreasing of silicon steel generates alkali mist which is neutralized in spray washer. The emission concentration of alkali mist is lower than 10mg/m3. (7) Control measures for waste gas generated from gas refining

In this project, gas purification process adopts FRC desulfurization and decyanation, ammonia washing and distillation, removal of thick ammonia and so on. At present, this gas purification process is an advanced and mature gas purification technology and widely applied in China. 3 This process can reduce the content of H2S in gas to below 200mg/m . In this project, bleeding gas and production tail gas generated by each process section of gas purification system are connected section by section and led into gas pipeline in a centralized way. The integrated measures are all practical and effective control means which not only have desirable effect, small investment and easy operation but also can recover useful products and increase energy, showing good environmental benefit and certain economic benefit. Therefore, these control measures are environmentally, technically and economically feasible. As shown from the above analysis, the intended project adopts advanced measures to control smoke gas, acid mist and oil mist. They are mature measures universally adopted in current smelting and rolling processes in iron and steel firms. Among them, dust collection technology has made marked headway in recent years, for example: sinter-plate dust collector, the mesh of its filter plate can be as small as 4μm, showing high dust collection efficiency, easy operation and adaptation to humid environment. In addition, new-type membrane filter material is characterized by high filtration efficiency and good gas permeability. The data (“Metallurgical Environmental Protection”, 2001 Issue 1 P.49) indicate: an iron & steel company uses homemade 729 membrane filter material to replace conventional 729 filter material in its raw material dust collection system. As a result, the dust concentration at outlet is reduced from 79.4 mg/m3 to 4.8mg/m3 and the dust collection efficiency is significantly increased. After the implementation of the above measures, the emission concentration of smoke gas is far lower than Grade 2 standard as defined in the Integrated Emission Standard of Air Pollutants GB16297-1996, and the emission of other pollutants all meets Grade 2 standard as defined in the Integrated Emission Standard of Air Pollutants GB16297-1996. Therefore, the environmental control measures of waste gas generated in the intended project are feasible and can ensure that the total emission concentration of smoke gas from the intended project is lower than 2300t/a. (8) Measures to ensure fugitive emission concentration at boundary reaches standard In order to reduce the generation and emission of fugitive dust from stock house, material transfer process and smelting process, the project installs air suction and dust removing systems in material transfer, blending and sieving locations, BF bins, cast houses, mixers and so on. The air suction points are strictly confined. Dust trap points working in different time are switched over with hydraulic valves and interlocked with process equipment to reduce air volume handled by the system, cut power consumption, ensure dust removing effect, control the fugitive dust of stock house within 100t/a and fugitive emission in production steps within

400t/a and ensure the concentration of smoke gas, SO2, BaP, H2S, NH3 and other pollutants at boundary reach emission standard. In order to avoid secondary dust, all dust discharged from dust collectors is humidified and

taken away by truck in a confined manner. The concrete control measures are as follows: a. Raw material preparation and transport system and intermediate slag yard The handling and transfer of raw material are key sources of dust in stock house. The design adopts preventive and control measures for all dust sources. The dust in stock house is controlled by spraying water. Material transfer tower mainly adopts mechanical dust removal method. a) In the design, totally confined stock houses are adopted for sintering, coking, BF, converter and limekiln, and water spray dust suppression facilities are arranged in a certain space to increase water content of the raw material in surface layer to a degree that ordinary wind speed won’t lift the material up. The speed of the vehicles entering the site is limited in order to prevent secondary dust. The powdery material stored in stock houses is reasonably dispatched to control the amount of the material in stock houses. If a large amount of powdery raw material needs storing a long time, crustizing agent will be sprayed on the surface layer of the powdery raw material to reduce the generation of dust. b) All transfer towers, pulverizer rooms, transport vestibules and other storage construction are confined to avoid pollution of fugitive dust emission. Floor washing and other water spray dust suppression facilities are installed in main dust generating points to prevent secondary dust generation. c) Dust hood is installed in each dust generating point, such as: head of pulverizer, head of belt conveyor, material receiving point, material charging point and material discharging point. The dust trapped by them is led to main pipeline of dust collector in the respective workshop where the dust is collected. b. Coke plant a) High-pressure ammonia injection smokeless coal charging technology is adopted. Large-scale dust collecting ground station is adopted for coal charging and coke discharging. The three groups of coke ovens install ground station separately and can basically realize smokeless coal charging and coke discharging. b) CDQ method avoids the dust and other pollutants (such as: H2S and NH3) generated during CWQ and can also recover the heat of red coke. c) Strictly control the emission of malodor-containing gas during gas refining and chemical product production. c. BF system a) Dust collection of BF cast house In order to effectively control the large amount of smoke gas generated during tapping, cast house dust collection system is installed and air suction hoods are arranged at tapholes, upper part of ladle and so on. b) Dust collection of BF stock bins and transfer towers

The dust collection system consists of dust collection points under BF stock bins, above BF stock bins and at transfer towers. d. Converter steelmaking system a) Converter secondary flue gas dust collection system Converter secondary flue gas dust collection system is used to remove the smoke gas fugitively emitted from converter during molten iron charging and steel discharging, the smoke gas that OG hood can’t collect during converter blowing, the dust generated during transfer of converter ferric alloy raw material, the dust generated during cutting of the steel slag bound on converter oxygen lance, the dust generated during transfer of converter auxiliary raw material and the smoke gas fugitively emitted during argon bubbling at argon bubbling station. Large pulse bag filter is adopted. b) Bulk material dust collection system Steelmaking raw material (active lime, mill scale, coke and other bulk material) is delivered by belt conveyor to elevated bin where a large amount of dust is generated during discharging. Dust collecting points are set at each bin top and discharge outlet of each discharge cart. The underbin discharge outlets are controlled by pneumatic valves. Some dust is generated when weighing hopper and vibration feeder work, so dust trap points are set respectively. Dust is generated in transfer towers during transfer of raw material due to elevation drop of belt conveyor, so dust trap point is set at the place where material falls from belt conveyor. A dust collection system is installed for the above dust trap points, which is a large pulse bag filter. e. Control of dust from road transport After the intended project is completed, the total output of steel will increase from 3.00mt in 2004 to 5.30mt. Meanwhile, material transport amount will increase in the plant accordingly, so will the dust generated from material transfer and vehicle transport inside the plant. As transport dust features complex aspects, long line and wide area, main effort shall be made in strengthening management and avoiding fall of raw material to the road surface. Meanwhile, dedicated persons and vehicles shall be assigned to clean and water the roads; all areas that can be greened in the plant shall be greened, and an around-plant green isolation belt of 5-10m wide shall be built. Through the above measures, the transport dust inside the plant can be basically controlled. 3.2.2 Prevention and control measures for main wastewater pollution sources and feasibility analysis In this project, wastewater mainly includes phenol-cyanogen wastewater, floor wash water generated in general stock houses and sinter process, and wastewater generated from ironmaking, steelmaking, steel rolling and other workshops. In order to prevent pollution of water body, most process technologies and facilities have no pollution or mild pollution, and pertinent measures are adopted to control the wastewater inevitably generated during the process. The treated industrial wastewater is reused in production to maximize reutilization rate and minimize consumption of fresh water. The main measures controlling industrial

wastewater include: (1) Treatment of phenol-cyanogen wastewater generated from gas refining

◆ Phenol-cyanogen wastewater is generated during gas cooling and recovery of byproducts and mostly includes the wastewater from ammonia distillation, final gas cooling water, condensed water of gas pipeline, and phenol-containing wastewater generated during the recovery of tar and other byproducts. The existing facilities of Meishan Chemical Branch generate 85.7m3/h of phenol-cyanogen wastewater. The intended project will generate 98.9m3/h. 110.4m3/h of diluting water (equipment indirect cooling water) is added. The total wastewater is 295m3/h. A/O2 phenol and nitrogen removing – biochemical process is adopted. ◆ Phenol-cyanogen wastewater treatment station consists of pretreatment, biochemical treatment, post-coagulation treatment and sludge treatment. The pretreatment part consists of flotation tank and equalization tank. Biochemical treatment adopts A/O2 biological nitrogen removing process and consists of anoxic tank and aerobic tank (O1; O2), reflux settling tank, secondary settling tank and blower. The biochemical treatment capacity is 300m3/h. Post-coagulation treatment mainly adopts physiochemical method to treat the water discharged from secondary settling tank. The treated phenol-cyanogen wastewater amounts to about 295m3/h and is sent to BF for slag flushing. The remaining sludge and the sludge of flocculation sedimentation tank are concentrated and dewatered by dewaterer. The sludge cakes generated are used for coal blending. The phenol-cyanogen wastewater from coking plant is deoiled by oil separation tank, and then pumped to gas floating device to further remove residual oil. The discharged water enters heat exchanger where it exchanges heat with the stripped wastewater from stripper. When the temperature is increased to 95~100℃, it enters the stripper from top and is sprayed down via stuffing layer and meets upward vapor. The stripper is separated into two parts from the middle. The upper part is for stripping and the lower part for regeneration. The two parts are separated by a bubble-cap tray plate. The wastewater is blocked by the plate from which it flows out of the tower. Most of the phenol in the wastewater is transferred to vapor phase. The mixed gas is blown to stripper bottom. In the stripper, it upwardly meets the NaOH solution sprayed down from the upper and middle sections of stripper’s lower part. The phenol in the steam is absorbed by lye. The steam after phenol removal treatment enters the upper part of the stripper again via bubble cap where it meets again the downward wastewater. The lower part of the stripper is heated with fresh steam and the temperature is maintained at around 105℃. Lye is circulated. When reaching specific concentration, it will be taken out and crystallized to get sodium phenol and the solution will return to the circulation system. The phenol-removed wastewater passes through heat exchanger to recover part of sensible heat. After that, it will enter neutralization tank where its PH value is adjusted to below 8 with H2SO4. Then, the water enters cooling tower where it is cooled down to below 45℃ and then enters four aeration tanks which are connected in serial. In the tanks, it is subjected to anaerobic and aerobic biochemical treatment. The outflow water enters sedimentation tank. The clarified liquid is pressurized by pump and enters sand filter for filtration. The water 56

flowing out of the filter can meet discharge standard. Part or all of the active sludge settled in the sedimentation tank flows back to the aeration tank. When the sludge concentration in the aeration tank is too high, part of the sludge will be taken out and dewatered by press filter. The dewatered sludge is to be used as raw material for coal blending. ◆ After removal of phenol and biochemical treatment, the concentration and removal rate of pollutants in the phenol-cyanogen wastewater at discharge outlet are shown in Table 3-8. ◆ Phenol-cyanogen wastewater treatment station is designed with a capacity of treating 3.20mt/a of phenol-cyanogen wastewater from coking facility and 0.30mt/a of phenol-cyanogen wastewater generated from coke processing (existing facility of Meishan Chemical Branch). The total water volume is 295m3/h. ◆ Treating coking phenol-cyanogen wastewater by A/O2 method is used by many metallurgical enterprises in China, for example: the coke plants of Jiuquan Iron & Steel Corporation and Taiyuan Iron & Steel Corporation. All the treated wastewater can be reused for BF slag flushing, sinter mixing, gas cleaning and ash flushing of power plant. It is proved by practice this process is economical, practical and feasible. ◆ In order to ensure phenol-cyanogen wastewater won’t enter into other water consumption systems and soil during reuse, dedicated transmission pipelines will be built to deliver treated wastewater to BF for slag flushing. During flushing, the water is evaporated. Necessary measures are taken to prevent seepage and leakage of the slag pond. ◆ Considering the possible equipment faults, a large equalization tank is built at phenol-cyanogen wastewater treatment station, the water level of the collecting well in wastewater treatment system is strictly controlled, the water feeding time is defined for each process section and the water impoundment of the collecting well is controllable. In the event the wastewater treatment system stops production due to persistent power failure or emergent condition of sump pump, the wastewater will enter equalization tank for temporary storage and immediate measures are taken to solve the failure and resume operation. Table 3-8 Concentration and removal rate of pollutants in treated phenol-cyanogen wastewater Unit: mg/L

Removal rate (%) 53.3 95 93 99.9 95.8 86

(2) Wastewater from sinter production The wastewater from sinter production is mainly floor wash water and equipment cooling

water from main factory building, vestibules and transfer towers. a. The equipment cooling water in sinter plant is not polluted except the temperature is raised.

This water will be reused after being cooled down by cooling tower and is not discharged to outside world. b. The intended 380m2 sintering machine will not discharge any industrial wastewater. However, the existing 2×130m2 sintering machines consume and discharge much water. It is suggested to eliminate or reform them. (3) Ironmaking wastewater Ironmaking step is a large water consumer, but the state-of-the-art ironmaking plant realizes zero discharge of industrial wastewater. The control technologies adopted mainly include water supply by quality, serial water supply, management of concentration rate, measured addition of chemicals, water filtration and automatic water makeup technology. As proved by production practice, these water conservation measures are effective. The large blast furnaces built in recent years in China all adopt these technologies. Therefore, the intended 3200 m3 BF system won’t discharge any industrial wastewater. a. Soft water closed circulating and cooling system adopts self-cleaning filter. Industrial clean water circulating and cooling system is provided with a bypass filter. Gas cleaning water circulating system adopts such measures as plate settlement, chemical addition, concentration, and filtration. As proved by the practice of ironmaking production, these measures play an effective role in maintaining the stability of water quality and the normal operation of the system. b. The net amount of circulating water totals 6740m3/h, the amount of circulating water is 6500m3/h and the amount of makeup water is 240m3/h. In order to stabilize water quality, 85m3/h of water is discharged to supplement slag flushing water circulation system and 15m3/h of cooling water is supplied to dust collectors to humidify collected ash. This system also adopts such measures as cooling, filtration and measured addition of chemicals. Water temperature and SS control measures are sound. Therefore, this system has no problem to maintain the stability of water quality. c. BF gas cleaning water circulation system In this system, the amount of circulating water is 1500m3/h, the amount of makeup water is 75m3/h, and water is discharged mainly by means of evaporation and sludge. The concentration rate is high, mainly because Bischoff gas scrubber can realize serial use of the wash water. As this system strengthens such measures as cooling, plate settlement, chemical addition, concentration and filtration, water temperature and SS concentration control measures are sound and the sludge formed is discharged together with gas slime. The actual operation results of 5# BF of Benxi Iron & Steel Corporation, 1# new BF of Anshan Iron & Steel Corporation and 6# BF of Kunming Iron & Steel Corporation indicate this system can operate stably without any doubt. d. BF slag flushing water circulation system

In this system, the amount of circulating water is 1500m3/h and the amount of makeup water is 247m3/h of which 60m3/h is phenol-cyanogen wastewater and 85m3/h is the blowdown from industrial water circulating and cooling system. As a large amount of water is evaporated or carried away by granulating slag, this system is under serious water deficiency, but due to the output of a large amount of granulating slag, scale (if any) will be carried away by granulating slag, too. It is proved by years’ production practice, this system has no such problems as scaling and blockage, but SS concentration in circulating water shall be controlled to prevent wear of water pump and pipeline. Therefore, new BF system can realize zero discharge. e. As Meishan Iron and Steel Company still has 2×1250 m3 BFs and a 1280 m3 BF which has undergone general overhaul, its water supply and drainage system is backward. Particularly, the 2×1250m3 BFs were built in 1970, their water supply and drainage system is backward and a large amount of water is consumed and discharged, so they should be eliminated or upgraded. (4) Waste water from steelmaking continuous casting The wastewater pollution sources in steelmaking process mainly include: equipment cooling water (water used by converter oxygen lance, LF, crystallizer and other equipment), converter gas cleaning wastewater, CCM casting mill scale wastewater, and continuous casting cooling wastewater which contains mill scale and a small amount of oil. a. Equipment cooling water: this water changes nothing except the temperature is raised. It is sent back to absorbing well after being cooled in cooling tower. From the well, it will be supplied to water consumers as per their need. In order to ensure the normal and stable operation of water supply, the system is installed with bypass filtration facility and water quality stabilizing unit and discharges a small amount of wastewater. b. Converter gas cleaning wastewater: Currently, the control of steelmaking wastewater is developing towards the direction of “circulated water supply, elimination of pollution, and comprehensive utilization”. In enterprises adopting wet method to clean converter flue gas, vertical sedimentation basin or radial sedimentation basin is universally used to eliminate horizontal sedimentation tanks, coagulation settlement replaces natural settlement and dispersant is used to solve scaling of circulating water. The intended converter adopts the technologies of “supplementing dirty water with clean water” and stabilizing water quality through bypass filtration and chemicals in water circulation system. As a result, water reutilization rate is raised to 97% and the generation of wastewater is reduced by process method. Two coarse particle separators and 8 plate settlers are used to treat the wastewater generated from dust removal of converter. Firstly, coarse particle separators are used to remove large dust particles (>60μm) accounting for 15% of the total SS in the water. After that, plate settlers are used to reduce SS concentration to below 100mg/L. The slurry in the settlers is filtrated with plate and frame press filter, and then is cooled and reused.

In the aspect of water quality stabilization, as lime is added during steelmaking as slag making material, a large amount of Ca2+ enters the wastewater generated from dust removal. The increase of Ca2+ results in the generation of scale during water circulation. If it is not handled properly, the circulation will become impossible and sewage has to be discharged. For this reason, mature and reliable chemicals are added into the water to settle down SS particles and prevent scaling. This treatment method is the most popular one in Chinese iron and steel companies. Three 300t converters in steelmaking plant of Baosteel adopt the above coarse particle separation – coagulation settlement – water quality stabilization method to purify water. Consequently, the overflow water of the settlers maintains below 50mg/L. The practice proves that the water quality can fully meet the requirement on the inflow water of sewage treatment plant. Moreover, the fine SS particles are usually settled down in radial sedimentation basin, whereas this project adopts more advanced plate settlers. The slurry settled from plate is filtrated with plate and frame press filter. The cakes are sent to sinter plant. The wastewater returns to the system for retreatment. In this way, a desirable settlement effect is achieved, the requirement on water quality is met, settlement area is increased and floor space is saved. This system is assessed feasible. For the intended converter, the total amount of industrial wastewater is 80m3/h with SS concentration of lower than 100mg/L, and other water discharge indexes all meet the requirement on the quality indexes of inflow water of sewage treatment plant. Its flow chart is shown in Fig. 3-2.

But, according to the study on multiple solutions to the filtration and utilization of the slurry generated from converter gas purification in domestic iron and steel enterprises, for example: baking cakes dry and then sending them to sinter process; adding lime into cakes and carbonizing them into coolant for steelmaking; sintering the cakes directly; not using plate and frame press filter but directly pumping the settled slurry to sinter process where it is fed into the first mixing machine for utilization, years’ practice proves that the approach of directly sintering slurry and sending it to the first mixing machine for use is feasible and reasonable. Chinese iron and steel companies like Baosteel, Shaoshan Iron & Steel Corporation and Jinan Iron & Steel Corporation all use this method. For this reason, we suggest abandoning plate and frame press filtration system and adopting the solution of directly sending slurry to sinter process for use.

c. Treatment of wastewater from continuous casting The treatment method for wastewater generated from continuous casting: wastewater→whirl well→advection sedimentation basin (with deoiling device)→filtration→reuse, without external discharge. This system mainly supplies CCM secondary cooling water, torch cutter granulation water, and mill scale flushing water. It adopts direct cooling. The backwater is not only hot but also contaminated (containing solid impurities like fine mill scale particles and oil). The sewage converges in scale ditch and flows into primary scale sump where large mill scale particles are settled down (the settled particles are taken out with grab bucket and filtered out water, then directly transported to sinter plant for comprehensive utilization). After that, part of the water is pressurized by pump and used to wash mill scale; another part of the water is pumped to chemical deoiling precipitator where the water is added with chemicals and undergoes secondary settlement treatment. The supernatant of the precipitator flows by gravity to hot water basin where it is pumped to sewage cooling tower. The cooled water is pressurized by pump and filtered with pipeline filter to control the diameter of impurities. After that, the water is reused. The mill scale sludge discharged from the bottom of the chemical deoiler is pressurized by pump and sent to plate and frame press filter for dewatering treatment. The cake sludge is loaded onto trucks by forklift and transported to sinter plant for comprehensive utilization. The filtrate of the press filter is sent to converter dirty circulating water system for reuse. This project adopts three-stage process, i.e.: whirl sedimentation basin → secondary advection sedimentation basin → filter → cooling, to treat the wastewater generated from continuous casting and rolling process. It is also a common method in China. The treatment of the wastewater generated from 1700 medium/thin-slab continuous casting and rolling of Anshan Iron & Steel Corporation, and the wastewater generated from the hot rolling plant of Panzhihua Iron & Steel Corporation all adopts this method. The intended thin-slab continuous casting and rolling facility will discharge 215m3/h of wastewater. The whole plant will discharge 500m3/h of wastewater from continuous casting and rolling process. The wastewater is discharged into the drainage pipeline in the plant and enters the intended reuse water treatment plant for unified treatment. The treated water will be reused as reclaimed water. (5) Wastewater generated from cold rolling The cold rolling wastewater of the new facilities mainly includes the equipment cooling water from cold mills, roller bearings and rollers, mill scale flushing wastewater generated during rolling, and the acid, alkali and oil-containing wastewater generated from plating and coating units. a. Equipment cooling water: this water is not polluted except that the temperature is increased. Therefore, this wastewater is reused after being cooled by cooling tower. The blowdown water of the cooling tower enters mill scale flushing wastewater treatment system and is not discharged to outside environment. b. Mill scale flushing wastewater: wastewater enters scale ditch→scale sump→(whirl

well)→deoiling unit→press filter→cooling tower→reuse. The concrete flow chart is shown in Fig. 3-3. The wastewater treatment device selected by this process is a mature method universally used in China.

Acidic/alkaline wastewater treatment system A circulating water treatment system is arranged for the acidic and alkaline wastewater discharged from cold rolling units. After being treated in equalization tank, primary neutralization tank, secondary neutralization tank, flocculation tank, reaction clarification tank, final neutralization tank and filtration, the wastewater is reused. d. Chromic wastewater treatment system This project has a chrome-containing wastewater treatment system with two-level deoxidation tank. Reducer is added into the deoxidation tank to reduce Cr6+ into Cr3+ and ensure the Cr6+ concentration in outflow water is below 0.5mg/L. the water is sent to reuse water treatment facility for further treatment. e. Waste emulsion and oily wastewater treatment system This project has a waste emulsion and oily wastewater treatment system in which paper filter is used to remove coarse particles in the wastewater, ultra filter unit is used to separate oil from water and the water is further treated with membrane bio-reactor to guarantee the discharged water meets discharge requirement. f. Waste acid regeneration unit A waste acid regeneration unit is installed to treat the waste acid generated from cold rolling mill in order to reduce the consumption of waste acid and convert waste into resources. Every water treatment system is provided with a sludge treatment system. g. When acidic/alkaline and chrome-containing wastewater is treated to reach Grade 1 discharge standard, it is further treated by hot slag splashing method or treated in general sewage treatment station and then is reused. In Taiyuan Iron & Steel Corporation and Benxi Iron & Steel Corporation, the wastewater is sent to general sewage treatment station for further treatment. In order to ensure acidic/alkaline wastewater won’t enter into other water consumption 62

systems and soil during reuse, dedicated transmission pipelines will be built to deliver treated wastewater to temporary steel slag yard. The slag yard is seepage and leakage resistant.

Considering the possible equipment faults, a large equalization tank is built at wastewater treatment station, the water level of the collecting well in wastewater treatment system is strictly controlled, the water feeding time is defined for each process section and the water impoundment of the collecting well is controllable. In the event the wastewater treatment system stops production due to persistent power failure or emergent condition of sump pump, the wastewater will enter equalization tank for temporary storage and immediate measures will be taken to solve the failure and resume operation. (6) Other wastewater Except the wastewater generated from main production steps in this project during production, the supporting production departments, such as: machine repair, oxygen generation, laboratory, transport and energy departments generate 345m3/h of wastewater in total. The main pollutant in the wastewater is SS. The wastewater is discharged into the drainage pipeline in the plant and enters the intended reuse water treatment plant for unified treatment. The treated water will be reused as reclaimed water. All domestic sewage generated by production and supporting departments can be treated in septic tanks and then discharged into the drainage pipeline in the plant and enters West Discharge Outlet. (7) Initial rainwater treatment On the premises of Meishan Iron and Steel Company, rainwater and sewage are separated. Initial rainwater is filtrated with the grids of rainwater well and then all enters the general sewage treatment plant for treatment. (8) General wastewater treatment station (general reuse water treatment station) Meishan Iron and Steel Company has made great effort and outstanding achievement in saving water in recent years. In 2003, the amount of makeup fresh water per ton of steel in the company (not including chemical and domestic water) was reduced to 16.34m3. Circulating water treatment facility has been universally used in every process step. The measures stabilizing water quality are advanced. Nevertheless, there are still a small number of users directly discharging wastewater. Due to topographic restriction, they directly discharge sewage into West Discharge Outlet. Moreover, the amount of discharged sewage from each circulating water system at each step is large, so the sewage needs to be treated in a centralized manner. In terms of water consumption indexes, the enterprise still has some gap from Chinese or foreign leading enterprises. In 2004, the consumption of fresh water per ton of steel was 12.1m3. Therefore, to continue to explore the potential of water conservation and reduce the unit consumption of fresh water is very essential for economically sustainable development of Meishan Iron and Steel Company. Meanwhile it is a matter of significance to reducing the pollution of water resources in the Changjiang River, improving water environment of Meishan Iron and Steel Company, protecting drinking water resources of the company, lifting the company’s social and public image and increasing the total amount of available water. It has remarkable social and environmental benefit.

Under the condition of adjusting product mix and increasing 2.30mt of steel production capacity, Meishan Iron and Steel Company sets its water consumption target as: 5m3 of fresh water consumption per ton of steel and 97.5% of reutilization rate of industrial water. For this reason, it is decided all industrial wastewater generated by the company will be intercepted at West Discharge Outlet, the general discharge outlet of Meishan Iron and Steel Company where the water is treated to reach the standard for industrial reuse water and then sent back to production steps for reuse. The intended general sewage treatment plant needs RMB110 million of investment, has a design treatment capacity of 100,000m3/d and will receive all industrial wastewater from Meishan Iron and Steel Company and partial domestic sewage from Meishan area. The plant is under design at present. The Environmental Protection Branch of the Central Research Institute of Building and Construction, MCC Group undertakes this design task. The inflow water is typical industrial wastewater of an iron and steel enterprise. Although it also includes some domestic sewage and contains organics, its biochemical treatment ability is poor and biochemical decomposition method is not suitable for it. The best method to remove such organic and inorganic pollutants is physiochemical method. In order to ensure the treated outflow water can be used as industrial makeup water, water softening step is added to remove temporary hardness during deep treatment of reuse water. Due to restriction of land area, high performance, energy saving and multifunctional equipment shall be reflected in every treatment unit. As the content of pollutants in the water coming from the plant area fluctuates considerably, direct treatment is difficult. Therefore, it is very necessary to retain the West Open Channel to regulate water quality. The process flow has the following features: As iron and steel wastewater contains oil, this solution is designed with deoiling equalization tanks to prevent the follow-up treatment effect from being affected; High-performance flocculation and sedimentation tank adopts the sludge backflow process of primary coagulation and secondary flocculation. While removing a majority of SS and organics in the sewage, it can also remove oil, iron, manganese and other trace pollutants. Plate settlement and sludge concentration clarify the outflow water. The post coagulation and chemical addition can raise the efficiency of Type D filter; Type D filter with 863 self adaptive filter material - comet fiber filter material as technical core is characterized by small floor space, stable quality of outflow water and easy operation and management. As the core process of this solution is high-performance flocculation and sedimentation tank and Type D filter, in order to ensure stable treatment effect, chemical adding equipment and control system supporting this process are all imported. The quality of inflow water required by the system and the realizable quality of outflow water are described in Table 3-9. Based on the quality of treated water, the wastewater will be reused as spray water of general stock houses, makeup water of the net circulating water at pre-ironmaking system and post-

ironmaking system, makeup water of dirty circulating water, and floor wash water of the plants. It can save 31.00m3/a of fresh water and reduce the consumption of fresh water per ton of steel in Meishan Iron and Steel Company to 5m3 from 12.1m3 in 2004. By now, the reuse water plant of Benxi Iron & Steel Corporation has been built up. Reuse water and fresh water are mixed in the distribution tank and then supplied to each process step through one pipeline. The effect is good. In contrast, the supply of reuse water currently being designed by Meishan Iron and Steel Company is separated from the supply of fresh water. It needs two pipelines to supply water to each plant and has no advantage in management and construction cost, so we suggest Meishan Iron and Steel Company carefully study the approach of Benxi Iron & Steel Corporation, learn from strong points to offset its weakness and adopt more reasonable and economical water supply method.

3.2.3 Analysis of noise control The main noise sources in this project: all kinds of production equipment, mixing machines, sieving machines, dust collection fans, air compressors, blowers, gas compressors and pumps should select low-noise equipment during design so far it is possible; for mixing machines, sieving machines and water pumps, mufflers are installed at each inlet of equipment and fan and outlet of air compressor; Dust collection fans, gas compressors, air compressors and water pumps are placed inside buildings separately; separate operation rooms, control rooms and rest rooms are arranged in workshops. Therefore, through sound insulation, screening of factory building walls, and air absorption and attenuation by distance, equipment noise at boundary can meet the requirement as specified in the Standard of Noise at Boundary of Industrial Enterprises. 3.2.4 Solid waste treatment and comprehensive utilization Iron and steel smelting generates a large amount of solid wastes, such as: BF slag, converter slag, ferric dust sludge, waste steel, tar residues, asphalt residues and industrial rubbish. These wastes are all useful resources in general. Through treatment, they can be reused. The treatment and comprehensive utilization of the solid waste generated by the intended project are shown in Fig. 3-6. All solid waste generated during production and operation of the project can all be recycled and reused or properly disposed. 3.2.4.1 Existing solid waste treatment and utilization facilities of Meishan Iron and Steel Company Meishan Iron and Steel Company pays great attention to comprehensive utilization of resources. It has set up Resource Comprehensive Utilization Committee to comprehensively coordinate the resource comprehensive utilization work of Meishan Iron and Steel Company. The comprehensive utilization of resources is managed by two departments. Manufacture Management Department is responsible for the utilization of “waste” resources and Safety & Environmental Protection Department is responsible for waste disposal. A resource comprehensive utilization company undertakes the comprehensive utilization of all wastes generated by the company. At present, all iron and CaO-containing dust sludge generated during production in Meishan Iron and Steel Company (such as: steelmaking dust ash, ironmaking dust ash, hot rolling sludge, sinter dust ash, coking coal dust and coke breeze) is blended into sinter raw material system and used as sinter raw material. Steelmaking sludge is pelletized and smelted in converter as steelmaking raw material. Steel slag is disposed by a joint venture steel slag company. Hot rolling mill scale is used to produce magnetic material. (1) Currently there are two 30 kt/a red ferric oxide magnetic material production line (built in 2001 and 2004 respectively). Steel rolling mill scale is used to produce magnetic material. This approach raises added value of mill scale, ensures mill scale is comprehensively utilized and generates better social and economic benefit. (2) In 2000, a 20 kt/a converter sludge pellet production line was built, which mixes converter sludge with limekiln leftovers, adds a certain amount adhesive and pelletizes the mixture and bakes it into finished pellets. The pellets are used as steelmaking raw material to substitute part of the iron ore and are reused in steelmaking converter.

(3) The dust collected by all dust collectors of Meishan Iron and Steel Company are all reused in production system. (4) In 2004, slag micropowder installation phase-1 project was completed. Some of the BF granulating slag in Meishan Iron and Steel Company is ground up in the slag micropowder production line. The powder is used as new-type building material. Part of it is sold out as raw building material. (5) Converter steel slag is delivered to the temporary storage yard north of the pump room to the west of the road at No. 25, Meishan at first. Then it will be treated by Nanjing Meishan Steel Slag Treatment Co., Ltd. After magnetic separation and sieving, waste steel is recovered and reutilized by Meishan Iron and Steel Company. The screenings is sent to wall material factories for comprehensive utilization. (6) Fly ash and slag are sold out for comprehensive utilization as raw building material. (7) Waste oil is transferred to other organizations for comprehensive utilization after going through required procedure strictly according to national regulations. 3.2.4.2 Solid waste disposal and utilization measures of the intended project (1) Sinter It is designed to reutilize the whole blending system. Sinter, ironmaking and steelmaking dust sludge and steel rolling mill scale are generally called ferric dust sludge. These solid wastes all contain ferric raw material, so they can be 100% utilized. (2) Ironmaking Solid waste generated in ironmaking step mainly includes BF slag, gas ash mud and dust ash. BF slag is pelletized into BF granulating slag. The BF granulating slag is used in cement building material industry and is a very popular base material. It is a widely adopted way of comprehensive utilization of BF slag. The utilization rate is 100%. BF gas ash and dust ash contain high iron. They are excellent sinter raw material and all utilized as sinter raw material. The gas slime recovered by BF gas cleaning system is very fine and sticky, creating difficulty for blending operation and affecting the quality of sinter ore. The gas slime in this project contains about 25~30% water. It is mixed with the return fines of sinter plant into pellets, which contain less than 10% water and can be utilized. This method can raise the air permeability of mixture and improve sinter process. (3) Solid waste generated from coking and chemical product processing The coal dust recovered from coal preparation system in coking plant is returned to coking coal process system for reuse; The coke dust recovered from coke discharging dust collection system of coke oven, the coke dust recovered from coking sieving dust collection system and the coke dust recovered from CDQ dust collection system are all humidified and then transported out of the plant by tanker; The tar residues discharged from mechanized ammonia separation tank, the asphalt residues discharged from ammonia distiller and waste solution from desulfurization process are all delivered to coal preparation workshop in a centralized way and blended into coking coal and 67

used for coking; The residues from the regenerator in crude benzol distillation section are added into tar tank.

The residues generated during tar separation and processing are blended into coking coal. The above control measures are common control means in domestic coking industry. They are economical, practical and effective and all comply with the regulations relevant with slag treatment. Therefore, the measures that the coking and chemical product processing project adopts to control solid waste is feasible. (4) Steelmaking There are many ways to utilize steel slag. The technology is going to become mature. With shallow tray hot splashing technology, steel slag has been successfully used as flux of iron and steel smelting, sinter burden and cement admixture. Dust ash and the converter dust sludge obtained after filtration by plate and frame filter and dewatering both contain high iron and low SiO2 and other impurities. They are sent to sinter plant where they are used as raw material for sinter production. This is also a popular method to treat converter dust sludge in China. From the perspective of production practice, the disposal technology is mature and reliable. The dust ash and converter dust sludge generate in this project are all delivered to sinter plant for comprehensive utilization. (5) Continuous casting and rolling The solid waste generated in this project includes mill scale, casting slag, precipitated sludge, waste oil and waste refractory. Except that waste oil is hazardous solid waste, others are all ordinary solid wastes. Among them, the waste oil recovered from deoiling facility in secondary advection sedimentation basin is drummed and sold out. At present, Anshan Iron & Steel Corporation adopts this method to dispose the waste oil generated from the sewage treatment system of 1700mm and 1780mm rolling mills. This measure is reliable. Mill scale and precipitated sludge are ferric dust sludge. They are disposed by a reliable method, i.e.: sent to sinter plant for comprehensive utilization; 65% of waste steel is recovered from casting slag. A small amount of residues are used to pave road. (6) Cold rolling Cold rolling facility generates waste steel, waste acid, water treatment sludge and zinc residues. a. Treatment of waste steel leftovers and ferric dust The steel sheet leftovers of slitting unit, skin pass mill and rolling mill in this project are all recycled and utilized. The ferric dust sludge is sent to sinter plant for reuse. b. Treatment of waste acid Waste acid comes from acid wash section. After treated in APU (acid purification unit) on the line, the waste acid is circulated and reused and won’t be discharged to outside. c. Sludge treatment The sludge generated from the radial flow sedimentation tank at neutralization station enters

sludge concentration tank and is treated with plate and frame press filter. The treated sludge cakes are sent to new landfill for disposal. Chromic sludge is sent to sinter plant and blended with material. d. Treatment of waste oil Meishan Iron and Steel Company has entrusted Wuxi Sandeli Chemical Co., Ltd. (hazardous waste operation license No.: JS.0282OOD040) to recover and utilize waste oil all the time. The main equipment of this company includes a set of waste oil regeneration equipment and two sets of grease production equipment. The main production process is as follows: Regeneration of waste oil: firstly heat waste oil to dewater it physically, and then add bleaching earth for physical slag settlement, filter it and add additives to complete the regeneration of waste oil. Grease processing: add waste oil, animal oil and lime in a certain ratio, then heat the mixture with steam to needed temperature, maintain this temperature for a specific time. In the end, grease will be generated. The regenerated oil and produced lubricant are sold by the company. Relevant agreement is described in annex. e. Zinc residues The galvanization of cold rolling generates about 550t/a of zinc residues. After recovery, it is sent to Yixing Jiangfeng Smeltery for treatment (hazardous waste operation license No.: JS0282OOD060). Relevant agreement is described in annex. f. Ferric oxide powder generated from steel rolling and acid wash processes, and mill scale are used to produce magnetic material by using the company’s existing facilities. 3.2.5 Control measures for general stock house (1) The general stock house of Meishan Iron and Steel Company mainly stores iron ore concentrate and anthracite. The general stock house is surrounded with isolation wall to prevent environmental pollution of dust. On days with strong wind, effort shall be made to minimize the transport of raw material to the general stock house. Water sprinkling devices are installed in the stock house. The sprinkling plan and amount are decided according to climatic characteristics to minimize dust generation from raw material layer. In addition, it is suggested to build protection forest and plant trees with luxuriant leaves and branches and leaf surface less sensitive to air permeation to minimize negative environmental impact of the dust generated from the general stock house. (2) Control measures of coal yard leaching water When there is plentiful rainfall, leaching water will be generated in coal yard. The leaching water contains pulverized coal and other water extracts. If the leaching water is directly discharged without any treatment, it will affect environment. It is designed to build closed ditch, collecting basin, grit removal chamber and other water treatment structures around the coal yard to reduce material loss, fallout and overflow and maximally avoid the uncontrolled overflow of the leaching water at coal yard. The water accumulated in collecting basin is used to sprinkle the coal yard. The pulverized coal inside grit removal chamber is transported back for production use on a regular basis to eliminate water impact of the leaching water generated by the coal yard. The control measure is feasible.

4. Analysis for Pollutant Meeting-standard Emission and Total

Amount Control

4.1 Determination of enterprise pollutant emission and total amount control quotas The total amount control for pollutants is one of the specific measures to improve environmental quality at present. The Nation requires definitely to implement the overall pollution emission amount control for the following pollution factors: SO2 industrial powder dust and smoke dust in waste gas, CODcr and ammonia nitrogen in waste water as well as solid waste. There are usually two methods to determine the total amount control of the project: one is that the local environmental protection department gives the overall pollutant emission amount to development organization according to local “total amount control” quotas (amount control quotas for pollutant emission in certain area); the other is to calculate the overall pollutant emission amount of the project according to environment assessment report, and then control the pollutant emission to meet the requirement of overall pollutant emission amount calculated from environment assessment report after the implement of the project according to the principle of “meeting-standard pollutant emission”. Meishan Iron and Steel Company is an old enterprise. Nanjing Municipal Environmental Protection Bureau gives it total amount quota every year, ant the quota reduces year by year. As for this project, the principle of total amount control is to increase the output without increasing pollution, bring up the old by the new, and reduce the overall emission amount of main pollutants by perfecting and improving environmental protection units. However, sinter ore increases a lot for the project, and it is without example for the actual use of sintering flue gas desulphurization. So the amount of the own ore is reduced so as to reduce the emission of

SO2. In this way, the total emission of smoke and powder dust and SO2 from Meishan Iron and Steel Company is reduced after the completion of the project. This chapter will analyze whether the overall pollutant emission amount meet the total amount quotas of powder and smoke dust, SO2 and CODcr in waste water given by Nanjing Municipal Environmental Protection Bureau. 4.2 Pollutant meeting-standard emission and total amount control analysis for planned project 4.2.1 Waste gas and its pollutant meeting-standard emission and total amount control （1） Waste gas meeting-standard emission analysis for planned project The main pollutant emission in waste gas after the waste gas pollutant source of planned project is treated is listed in table 3-5. From the table we can see that the main pollutant emission can meet the standard. （2） Total amount control quotas for waste gas and its pollutant in the whole company The overall amount of waste gas pollutant emission given to Meishan Iron and Steel

Company (including Meishan Chemical Subcompany) by Nanjing Municipal Environmental Protection Bureau in 2004 is in table 4-1. In order to assist the construction of the project, the

Bureau increases the overall SO2 emission by 2000t through the deployment inside the city. The overall emission of smoke and powder dust stays the same. The waste gas pollutant emission of the whole Meishan Iron and Steel Company is also in table 4-1. From the table we can see that the total amount control quotas for waste gas and its pollutants meet Nanjing total amount quotas requirement. Table 4-1 Waste gas as well as its main pollutant emission and total amount control quotas Pollutant (t/a) No. Project Smoke and powder dust SO2 Emission amount of the whole Meishan 1 Iron and Steel Company plant after the 6057 17243 completion of the project Total amount control quotas given by 2 Nanjing Municipal Environmental 10600 19000 Protection Bureau in 2004 3 Total amount control quotas added in 2005 2000 Whether meet the total amount control 4 Yes Yes quotas Note: Emission amount of pollutants reckoned in inorganizational discharge source. 4.2.2 Waste water and its pollutant meeting-standard discharge and total amount control quotas After the project is completed and put into production, waste water of the whole plant will be treated by planned sewage-treatment plant uniformly and then used as heavy water. The discharge amount is 2.52m3/t.steel (1.35 when thermoelectricity, Meishan Chemical Subcompany and sanitary waste water are excluded). The waste water discharged from west discharge port and treated to meet first-level discharge standard through the year is 1145 m3/h. The discharge quality is in Table 4-2. The annual waste water discharged from west discharge port to Yangtze River is 10,030,200 m3. The clean recycling condensate and steam condensate of Coking Subcompany and Meishan Chemical Subcompany discharged from north discharge port are 379m3/h and 332.004m3/a. After the completion of the project, the total waste water discharge amount will be substantially reduced, and phenol and cyanide waste water, acid and alkali waste water as well as chromic waste water will not be discharged to outside. So the water pollutant discharge amount to Yangtze River from west and north discharge ports will be substantially reduced. And COD will be reduced by 1630.5t/a, the reducing rate being 66%. In this way the influence on the water environment of Yangtze River will be evidently reduced. See Table 4-2. 71

4.2.3 Solid waste emission amount control quotas

The solid waste produced by planned project will be 1622079t/a. After the project is completed and put into production, the solid waste produced by all projects of the company will be 3494197t/a. The sludge (16850t/a) from sewage-treatment plant will be sent to the municipal solid waste landfill, and the rest will be recycled and reused. No industrial solid waste will be discharged to outside. 4.3 Analysis for total amount control With Product Matrix and Process Equipment Upgrading and Technical Transformation Project being completed and put into production, some old establishments will be reformed or rebuilt. Specific environmental protection measures against igorganizational discharge will be adopted. So the total emission amount of smoke and powder dust after the completion of planned project will be reduced by 4631 t (43.3%). SO2 will be reduced by 1325 t (7.7%) and achieve the goal of “increasing output without increasing waste” by desulfurizing the three boilers in power plant and reducing the amount of the own ore. Compared with current situation, the influence of TSP to atmosphere environment quality substantially reduced after reducing the emission amount, and the influence of SO2 and P M10 changes a little.

5. Environmental Risk and Accident Discharge Analysis

Environmental risk, caused by nature and human behaviors and spread by environmental medium, describes the happening probability and result of adverse accidents that exert ruinous, damaging, and destructive impact on human society and natural environment. ERA (Environmental risk assessment) is a process for estimating the likelihood of sudden disastrous accidents related with the project and environmental influence resulting from accidents, and making appropriate measures. The major materials for project, benzene and coal gas in products are flammable or explosive substance; ammonia water, NaOH, hydrochloric acid, chromic acid, etc. are strongly corrosive materials. It is essential to take efficient and stringent risk-control measures in terms of technology and management for preventing potential environmental risk existing in materials transportation and storage, as well as usage. The abnormal operation and damage of environmental treatment facilities during production will lead to off spec pollutant discharge resulting in affecting environmental quality. 5.1 Risk factors Identification The environmental risk identification for the project: on the one hand, start with raw materials, assistant materials, and products involved in the project, understand the potential risk of these chemical materials, including flash point, melting point, boiling point, self ignition point, explosive limit, risks and toxicity classification, etc.; on the other hand, proceed with production process and design scheme, understand device composition of project and its corresponding supporting and auxiliary facilities, important production equipment, process parameters, materials quantity and potential risk of all devices, analyze key positions and weak points of all devices; finally, analyze potential factors of accident discharge. 5.1.1 Risk factors identification of raw materials, assistant materials, and products The major raw materials, interim products and final products involved in the project contain benzene, coal gas, ammonia, tar, NaOH, sulfuric acid, etc., characterized in fire, explosive risk and poisonous damage to some extent. Fire risks grades of major materials are listed in the following table 5-1. Table 5-1 Characters and fire risks grades of major materials No. Materials name Explosive limit％ Flash point Fire risk grade 1 Ammonia 15.0～30.2 132 II 2 Benzene <28 IB The harmful effect and occupational harm degree classification of major poisonous materials are listed in table 5-2 respectively.

5.3.1 Disaster emergency plan against sudden accident Disaster emergency plan, prepared in advance, is the work procedure and specific measures with definite purposes, in order to provide clear action guide to personnel on site, making them take their time, properly deal with the problems in time, instead of pushing the panic button or discussing and studying on measures temporarily after various serious and malignant emergencies occur, so as to reduce personal injury, property and economic loss. Before planned project being put into production, enterprise shall, according to specific production process flow, set down disaster plan action scheme to effectively deal with sudden accidents. The scheme shall be approved by related department, and fully coordinated with actions of plant, local government and all service departments (e.g. fire fighting and medical). Disaster plan is made against serious risk accidents, which shall meet requirements as follows: a. panic alarm method on site; b. evacuating personnel on site in a safe manner; c. rescuing and treating injured personnel; d. controlling the further development of accidents, minimize the property loss and environmental damage; e. ensuring affected area shall be recovered to normal as soon as possible. Implement the disaster plan when an serious risk accident occurs or is about occur. 5.3.2 Emergency measure against sudden accident Although precaution is the essential measure against accidents, some emergency measures, if proper, shall be taken to reduce accident spread range and loss after accidents, and vice versa. Emergency measure is the plan after basically determining risk loss, aiming at overall recovering the interrupted production process due to serious risk accidents as soon as possible, reducing further loss and minimizing the affected degree. Emergency plan shall include not only the related measures to be adopted, but also corresponding duties of different working posts. In case any environmental accident occurs due to various faults and accidents, relevant emergency measures shall be taken immediately depending on characteristics and generating reasons, to control affecting range and degree. The core of accident treatment is to alarm in time, decide correctly, remedy rapidly. Treatment measures shall be sufficient to take efficient actions. With regard to the above-mentioned environmental risks, the emergency measures shall be as follows: a. If material splash and leakage occurs due to equipment failure or operation fault, shutoff valves and stop supplying materials at once. The overflowing materials shall be cleaned 78

immediately to store in the container for proper disposal; do not discharge with garbage or sewage, so as not to harm environment. b. For any material leakage accident due to such causes as machine damage during storage and transportation, stop leak at once, clear environment, try to collect overflow and leakage materials into sealing containers, absorb residual solution with sands or inert absorbent, and displace it to safe positions, do not discharge it at will. c. Attach great importance to some flammable, explosive or corrosive materials and products used in the project, as they are easy to cause fire during sudden accidents. Once fire happens, put out fire source at once with dry powder, CO2 fire extinguisher. In case of conflagration, call fire telephone, and connect with fire hydrant at once. Sprinkle to disperse steam of combustible materials, and put out the fire with CO2 fire extinguisher or sand. d. Corresponding emergency measures shall be adopted for other accidents. 5.4 Accident discharge and measures 5.4.1 Failures of sewage disposal facilities and measures （1）Failures of sewage treatment facilities During operation of sewage disposal station, any failure due to operation accident or other causes may result in degraded disposal effect or complete failure, putting an adverse impact on equipment, and discharge will lead to pollution to environment. （2）Major precautions against failure of sewage disposal equipment . Strengthen on-the-job-training for personnel of sewage disposal plant, improve professional quality, be strict with operation regulations; . Enforce regular management and maintenance for sewage disposal equipment; . In order to prevent off spec outlet water quality discharge caused by operation faults occurring in sewage treatment station, it is suggested that measures of reducing and even stopping production shall be taken once sudden accident happens. Equalization basin shall be provided for phenol-cyanogen wastewater disposal station and acid and alkaline wastewater disposal station. Stop the overall procedure producing wastewater if facilities failure longer than 4 hours. 5.4.2 Waste gas accident discharge and measures Waste gas treatment facilities failure means during operation of dust collectors, due to operation fault, cloth damage, power off or other reasons, the dust collection efficiency of electric dust collector, cloth dust collector drops or is completely out of work, causing pollutant concentration in waste gas to considerably rises, and resulting in contaminating environment. All dust collector devices for planned project are provided with on-line monitor; once off spec discharge happens due to equipment damage, corresponding measures shall be taken at once to stop production and overhaul, and long-period off spec discharge is not allowed. （2）Major precautions against waste gas treatment facilities failure 79

Strengthen on-the-job-training for personnel involved in waste gas disposal facilities, improve professional quality, and be strict with operation regulations.

. Enforce regular management and maintenance for such equipment as electric dust collector, cloth dust collector, and maintain and replace with new parts on a regular basis. . Cloth dust collector shall be made of new durable fiber material to improve usable lifespan. In order to prevent off spec waste gas pollutant discharge due to operation failure of dust collection facilities, remedy sudden accidents in time; if this isn’t feasible, reduce production and even stop production. 5.5 Comprehensive measures against environment risk To sum up, in order to avoid serious accidents, it is essential to enforce the risk awareness and environmental awareness education to every cadre and employee to strengthen safety and environmental protection awareness. Thus it is suggested to （1）Strengthen work post responsibility, be strict with all operation rules and rewards and punishment system. Besides special environmental protection organizations, specially-assigned personnel shall be provided for each production department with responsibility for safety and environmental protection of its department, often checking sectors easy to cause faults so as to eliminate hidden danger; reporting any problems found out to related department; （2）Arrange all personnel to go through emergency treatment drill on a regular basis for accidents, being capable of averting perils with precautions, and keeping busy but orderly even in case of accidents;

（3）Further to improve security and fire-fighting equipment outfit, strengthen construction of fire-fighting and security teams, so as to consistently promote the abilities of emergency response;

（4）Strengthen equipment maintenance and management, create strict operation system and emergency scheme; reinforce management of hazardous materials, set down all-around regulations for storage, transportation and usage; lay down strict check and register system for key departments and posts. To sum up, if effective precautions are taken, risk accidents can be limited to production site, and controlled rapidly and effectively, instead of causing great loss to production, personnel, and property, and affecting the areas outside factory and its surrounding neighborhoods.

7.3 Result of Public Poll 7.3.1 Statistics of the Poll (1) With the status quo of environmental quality at the project location area, 35 persons are very satisfied, 166 persons are relatively satisfied, 141 persons are not satisfied, and 62 persons are very dissatisfied; (2) About the planned project, 44 persons know nothing, 333 persons know something, and 27 persons know clearly; (3) About the harm or affect by the project, when completed, on the local environmental quality, 61 persons think it will be serious, 96 persons think it will be a little serious, 193 persons think it will be just so so, 37 persons think it will be not so serious, and 17 persons have no ideas; (4) In terms of the attitude towards this project, 8 persons are strongly for it, 300 persons are for it with conditions, 14 persons do not care about it, and 8 persons are against it. 7.3.2 Public Suggestions and Demands Most of the people visited during the public poll put forward their views and demands in the column of Public Suggestion & Requirement, of the 404 people, 314 people filled in this column, the participation rate is up to 78%, very seldom in the public polls carried out before. This shows that the local people have a very strong sense of involvement, very concerned with environmental protection, their own interests, as well as the social development and progress. The views and comments of people visited are given in the summarized form of Table 7-2, based on the proportion of people with different opinions.

Table 7-2 Public Comments and Demands

Comments & Demands No. of persons Proportion Sequence

Support the project 8 2% 6 Improve environmental control and emission to the 88 21.8% 3 standards Protect the environment 139 34.4% 1 Ask for relocation 62 15.3% 4 Improve construction management 10 2.5% 5 Suggest for landscaping 8 2% 8 Ask for economic compensation 4 1% 7 Demand for better environmental supervision 4 1% 8 Protect people’s interests and economic compensations 7 1.7% 7 Number of persons that didn’t fill in this column 90 22.3% 2 From the table, the following points of views are derived: Most of the people believe that construction projects are important to facilitate the local social and economic development and promote entrepreneurial boom, but full attention should be paid to environmental protection in the course of project construction, that is why those suggestions concerning environmental protection rank top in the percentage. Many people wrote a lot in this column, expressing that the construction project is a good thing for local development, but also worrying that possible environmental pollutions may endanger their own homes. The people visited during the public poll this time have a strong environmental awareness, they put forward a lot of suggestions and comments on strengthening management of emissions to standards, covering the aspects from project design, construction, three wastes control, cleaner production, environmental management and supervision, and some of their views and opinions are very wise, and keep to the point. For example, an old gentleman named Fan Yue-tai made 6 recommendations covering processes like coking, sintering, steel-making, iron-making, rolling, environmental supervision and monitoring program. One of his suggestions is that coking process must be provided with equipment for coal feeding and coke pushing and dust removal, with application of CDQ technology. And full negative pressure process shall be used in gas refining, and hydrogeneration process be used in benzene fine processing, with the gas concentration after desulfurization below 200mg/m3, etc. Such suggestions are very good indeed, very high in reference value. It also shows that public involvement during environmental impact assessment (EIA) really means much in reality. During the public poll this time, the people in Huangnitang, Zhushang, Zhushan and some other villages asked for relocations to places further away from the plant area. These people asking for relocation are those residents on the whole who are to be relocated for the current project, and their main reason for relocation is serious air pollution, heavy dust near the plant area, a smell of sulfur dioxide and other smells. Some people complain about noises and poor water quality. The relocation plan to be carried out for the current project is in line with the requirements of these people, as detailed in the scope of relocation shown in the plant layout plan.

121

Some other advices and comments are of good reference value, too, such as those on strengthening management during the construction phase, protection of people’s interests, a good job in environmental supervision, a good planning of the areas for relocated people, and so on. 7.3.3 Analysis of Objections Of the public poll, there are 8 persons who have objections to the project, covering 2% of the poll sheets, the project owner is supposed to pay due attention to them in spite of the small percentage they have. Of the 8 persons against the project, 4 persons filled in their reasons for their objections while the other 4 did not. However, of the 4 persons who didn’t mention their reasons for objection, 3 persons did wrote down their requirements and suggestions in the column of Intended Suggestion, in which they also mentioned atmospheric pollution, water pollution and noise pollution. We think it is normal protection of individual rights for good environment. Of the 8 opposers, 7 persons made suggestions in the column of Intended Suggestion that the project owner should strengthen pollution control and make it to do emissions up to standards. This shows these persons are not resolute opposers, on the other hand it means they do not have specific reasons for their objections. See Table 7-3 for the analysis of the specific objections. Table 7-3 Analysis of Objections

Yin Yi-lin Asking for solution to During the intended construction, Further environmental Meishan Iron & Steel Company should do Hu Hong-yan identification of pollutions, one person more in presentation to the local residents, pollutions is to Zhu Jun clearly means it is environmental protection, and protection be made Hang Jun-hong atmospheric pollution of the legal rights of the people.

Zhang Yu-xi

The construction owner should inquire This is a just with this person about noise impact. If Liu You-gen Loud noises opinion. production noises have impact to his life, it should be settled down.

Not clear—what Xie Yun To solve problems problem? The objections in the public poll are mainly on the worry over environmental pollutions, so the project owner should, during the construction, do its best in the environmental protection and pollution control to the satisfaction of the people, and carry out immediate solutions to pollution problems that upset people. On the other hand, the project owner should do more as much as possible to explain to the people and masses about those issues of their concern, so as to dissipate their doubts and have their support for this construction project.

The fuels used include coke, coke oven gas, BF gas, converter gas, hard coal and so on. In 2004, Meishan Iron & Steel and Baosteel Chemical emitted 7206225×104m3/a of non-fugitive waste gas, 999t/a of smoke gas, 2724.6t/a of dust, 18156t/a of SO2 and 7637.38 t/a of NOx. The pollutants contained in the fugitively emitted gas are dust and SO2 with an emission amount of 6965t/a and 412t/a, respectively.

10688t/a of smoke (dust) and 18568t/a of SO2 are emitted in total. (3) Major environmental issues The fresh water consumption per ton of steel is 12.1m3 and there are a considerable number of once through systems. It is needed to upgrade the existing circulating water

124

systems with low circulation rate to realize serial sewage discharge and raise circulation rate; The amount of fugitive dust is large, existing coke ovens and BF cast houses in particular;

Coke oven gas is not all desulfurized. The emission of SO2 in gas is large; The sulfur content of self-owned ore reaches 0.42%. In the future, the percentage of import ore must be increased so as to reduce the overall sulfur content of ore and when the condition is ripe, desulfurization of sinter flue gas shall be undertaken; The water supply and discharge in Meishan Chemical Branch is large. More than 90% of it is directly discharged water, causing considerable waste; Phenol-cyanogen wastewater is discharged without reaching discharge standard. 8.2 Overview of the intended project Main facilities of the intended project are listed in Table 8-2. 8.2.1 Main construction content and compliance to industrial policy From Table 8-2, it can be seen that the new project under the Product Matrix and Process Equipment Upgrading and Technical Transformation Project of Meishan Iron and Steel Company meets the requirement of industrial policy in terms of technical scale. Meanwhile, the coke oven of this project is provided with CDQ, BF TRT and pulverized coal injection. All waste heat and energy of sinter, converter and steel rolling are recovered and utilized, all gas is recovered, and the remaining gas is used to generate power and produce steam. The overall energy consumption per ton of steel in this project is 0.683t of standard coal and the consumption of fresh water per ton of steel is 4.7m3. Therefore, this project meets the Development Policy for Iron and Steel Industry. Moreover, Meishan Iron and Steel Company is subordinate to Baosteel Co., Ltd. Baosteel Co., Ltd. is a super large iron and steel business conglomerate in China. The industrial policy encourages it to appropriately expand scale and its subordinates to adjust and upgrade their product matrix to further enhance international competitiveness. Therefore, this project tallies with the goal of the industrial policy and its requirement on adjustment of industrial layout. Meanwhile, all external conditions of this project are possessed: (1) The intended project mainly uses imported ore and relies on the import of Baosteel Co., Ltd.; (2) By building a general sewage treatment plant, the intended project won’t increase the amount of fresh water of the company as a whole; (3) Take the reform measure of “pushing ahead old by new” to realize the goal of output increase and pollution reduction; (4) Coal, ore and lime use the transport conditions of the current supply channels. Only new raw material and finished product terminals need to be built.

After treatment, the emission of pollutants complies with Grade 2 standard as defined in the Integrated Emission Standard of Air Pollutants GB16297-1996, the Emission Standard of Air Pollutants for Industrial Kiln and Furnace BG9078-1996 and the Emission Standard of Air Pollutants for Coke Oven GB16171-1996. Therefore, the environmental protection measures for waste gas pollution sources of the intended project are feasible. (2) Analysis conclusion on the feasibility of environmental protection measures for wastewater The water use of the intended project adopts a series of techniques to conserve water resources, such as: separation of dirty and clean water, circulated use, multiple use, “blowdown” in reasonable serial connection, and water quality stabilization. The main pollutants in clean circulating water system and dirty circulating water system are SS, ppetroleum and temperature rise. The water is circulated and reused after cooling and precipitation treatment. The water discharged in a small amount is led to the company’s sewage treatment plant where it is treated and sent back to production for reused. The reuse rate is 74.4%. Phenol-cyanogen wastewater is treated separately to reach standard, and then is used to flush BF slag. Acidic/alkaline wastewater (chromic wastewater) is treated separately to reach standard, and then is used to treat steel slag. As a whole, the project once completed will significantly reduce the amount of wastewater discharged into the Changjiang River. The wastewater still needing to be discharged in a small amount will be discharged after it is

130

treated to exceed Grade 1 standard. Therefore, it is believed the control measures for wastewater pollution sources of this project are feasible.

(3) Analysis conclusion on the feasibility of environmental protection measures for noise Sound insulation, sound silencing, sound absorption and vibration reduction measures are adopted for noise sources according to the nature of the sound source to reduce environmental impact of noise. They are environmental protection measures universally adopted by iron and steel companies and feasible. (4) Comprehensive utilization and treatment of solid waste The intended project will generate 1,622,079t/a of solid waste, mainly including steel slag and recovered ash and sludge which can completely recovered and utilized. The solid waste generated in coking gas refining process is directly sent back to prepare coal. Only the sludge generated by the general sewage treatment plant is treated by municipal administrative institution and amounts to 16,850t/a. Therefore, the solid waste generated by the intended project won’t affect ambient environment. 8.3.2 Assessment conclusions on clean production (1) The comparison between the current clean production level of Meishan Iron and Steel Company and indexes indicates that 10 items are in Grade 3 level, 12 in Grade 2 and 14 in Grade 1, a sound environmental management system is yet to be established and the level of clean production is in around Grade 2. The comparison with the intended project reveals that the principal gap lies in the facts that coking process doesn’t adopt CDQ, sintering machines don’t all lay hearth layer, and water consumption and discharge are large. They are the very goal for current and future technology renovation of Meishan Iron and Steel Company. (2) The production process and equipment adopted by the new coke oven reach Grade-1 level; resource utilization and product and waste recovery all reach Grade-1 level; the indexes for the production of waste gas pollutants all reach Grade-1 level, and the amount of particular waste gas pollutants reaches Grade -2 level (including the tar processing facility of Meishan Chemical Branch, so the wastewater generated during ammonia distillation is more than that generated from a simple coking facility). Therefore, it can be determined the clean production indexes for new coke oven is in Grade-1 level as a whole. (3) In consultation of the “cleaner production standard” for iron and steel industry (draft for comment), the intended project has two indexes in Grade 2 level, 4 in or above Grade 3 level (mainly resulting from the high sulfur content of sinter), and 23 in Grade 1 level. In addition, the intended project will establish and implement ISO 14001 environmental management system as per the requirement of Grade 1 standard. Therefore, it is assessed that the clean production level of the intended project can reach Grade 1 level. (4) The total energy consumption of the intended project is 1.5709 million tons of standard coal and its comprehensive energy consumption per ton of steel is 683kgec, meeting the access condition (700 kgec/t of steel) specified in industrial policy. Compared to major large iron and steel enterprises in China, the energy consumption indexes in each process step are advanced and the energy consumption indexes in main process steps are better than the current average level of Baosteel.

(5) After the intended project is completed, Meishan Iron and Steel Company plans to upgrade existing backward equipment in succession. To coordinate the construction of environmental protection facilities under the “pushing ahead old by new” project, Meishan Iron and Steel Company will ensure all production facilities reach the level of this intended project, all clean production indexes of the company reach current Grade 1 level and the consumption of fresh water per ton of steel below 5m3 and comprehensive energy consumption per ton of steel less than 700kgec by the end of the “11th Five-year Plan” period. 8.3.3 Assessment on up-to-standard pollutant discharge and total amount control (1) Up-to-standard discharge of current pollutants All non-fugitive waste gas emission sources in the existing facilities of Meishan Iron and Steel Company reach emission standard;

The sewage in the company is discharged after reaching standard, except that CODcr and

NH3 contained in phenol-cyanogen wastewater discharged from North Discharge Outlet exceeds specified limits; (2) Up-to-standard discharge of pollutants generated in the intended project The intended project strictly observes applicable pollutant discharge standards. Except converter primary flue gas, the emission concentration in every smoke gas emission source is controlled below 40mg/m3 (electro-precipitator) and 30mg/m3 (bag type dust collector), and all heating furnaces use clean gas. The emission concentration in thermal power plant and heads of sintering machines is much lower than respective emission limit; All industrial sewage generated in the intended project (except phenol-cyanogen wastewater and chromic wastewater) enters the general sewage treatment plant for treatment. After treatment, 74% of it is reused and 26% of it is discharged as per Grade 1 standard; Except that the sludge generated by the general sewage treatment plant is sent to municipal rubbish landfill, all other solid waste generated by the intended project is recovered and utilized and no hazardous and harmful solid waste is discharged. (3) Total amount control measures The total emission amount of air pollutants generated by existing facilities and intended facilities of Meishan Iron and Steel Company and the whole company after the project is completed is shown in Table 8-4. Table 8-4 Table for control of total emission amount of waste gas pollutants (unit: t/a) Emission Total amount Current Emission Total emission reduction Increase/ control index Pollutant emission increase from of the company through decrease and set by factor of the intended after the project “pushing percentage (%) environmental pollutants project is completed ahead old by protection Smoke gas 10688 6910 2279 -4631/-43.3 6057 10600 (dust)

a. The amount of smoke gas emitted by existing facilities is slightly higher than the set total amount index, but fugitive emission accounts for a large percentage, causing obvious impact on the quality of surrounding air environment. The total emission amount of SO2 is close to the total amount index; b. The intended project will emit 2,279t/a of smoke gas and 6987t/a of SO2; c. After the project is completed, Meishan Iron and Steel Company will totally emit

6,057t/a of smoke gas and 17,243t/a of SO2. The emission amount of smoke gas is reduced by

4,631t/a and SO2 by 1,325t/a than the present level. The construction of the project meets the requirement on total amount control; d. As a general sewage treatment plant is built, after the project is completed, the amount of discharged wastewater will decrease by 1,541.832t/a than the present, and the discharge of CODcr will be reduced by 1,630.5/a with a value much lower than the total amount index. 8.3.4 Conclusions on the feasibility of site selection (1) The work with regard to land acquisition for the intended project near the current plant area is under the way. The land has been included into urban master plan. Procedures for land use are proceeding. Demolition and relocation plan is being implemented by government department. Obviously, this project complies with Nanjing urban master plan. (2) The intended project is located in Banqiao new town, Nanjing City, which belongs to Category 2 functional zone of ambient air quality. Although the intended project will emit a small amount of pollutants, through controlling (eliminating) the current pollution sources by measure of “pushing ahead old by new”, the total emission of main pollutants in waste gas generated by Meishan Iron and Steel Company will be reduced by about 43.3% and the emission of SO2 will be reduced by 7.1% after the project is completed. The forecast analysis indicates the impact of Meishan Iron and Steel Company on ambient air quality is lightened to some extent. (3) At the villages within the sanitation protection distance of this project, 1160 households including 2230 people are affected. A plan has been worked out to relocate all of them. (4) The intended project has no obvious impact on surrounding ecological environment. (5) The intended project closely relies on the existing infrastructure facilities of the company, minimizes the occupation of land and reduces impact on ecology and environment. After fully considering the impact of positive and negative factors, the assessment believes the site selected is feasible, but the construction unit shall give full consideration to the suggestions described in 7.4.3. 8.3.5 Assessment conclusions on current status of ambient air quality and impact (1) Assessment conclusions on current status of ambient air quality Around Meishan Iron and Steel Company, 12 monitoring points are arranged (monitoring time: April 2005). The monitoring results are assessed as follows: Through statistics and analysis of monitoring results, the pollution of atmospheric

133

environment by various kinds of pollutants in the assessed area can be known and is described separately as follows: 3 The range of hourly SO2 concentration is 0.003-0.171mg/m and that of daily concentration is 0.003-0.077mg/m3. Neither hourly concentration nor daily concentration in each monitoring point exceeds the specified limit. 3 The range of hourly NO2 concentration is 0.006-0.098mg/m and that of daily concentration is 0.009-0.063mg/m3. Neither hourly concentration nor daily concentration in each monitoring point exceeds the specified limit. 3 The range of daily PM10 concentration is 0.086-0.439mg/m . In the whole assessed area, the daily average concentration in every monitoring point exceeds the specified limit. The range of daily TSP concentration is 0.171-3.094mg/m3. In the whole assessed area, the daily average concentration in every monitoring point exceeds the specified limit. The range of hourly F concentration is 0.13-5.00μg/m3 and that of daily average concentration is 0.48-4.14μg/m3. Neither hourly concentration nor daily concentration in each monitoring point exceeds the specified limit. The range of daily B[a]P concentration is 0.0011-0.0365ug/m3. Except 9# monitoring point (aside the original coke oven), in the whole assessed area, the daily average concentration in each monitoring point doesn’t exceed specified limit. 3 The range of NH3 primary concentration is 0.01-0.01mg/m . In the whole assessed area, the primary concentration in each monitoring point doesn’t exceed specified limit. 3 The range of H2S primary concentration is 0.001-0.003mg/m . In the whole assessed area, the primary concentration in each monitoring point doesn’t exceed specified limit. The range of hourly HCl mist concentration is 0.007-0.032mg/m3 and that of daily average concentration is 0.008-0.014mg/m3. Neither hourly concentration nor daily concentration in each monitoring point exceeds the specified limit. The range of chromic acid mist primary concentration is 0.001-0.009mg/m3. In the whole assessed area, the primary concentration in each monitoring point doesn’t exceed specified limit. From the above analysis result, it can be seen that: the current status of ambient air quality in the assessed area exceeds Grade 2 standard as defined in the Ambient Air Quality Standard. (2) Conclusions on ambient air quality impact assessment The forecast on the concentration of air pollutants indicates: after the intended project is completed, Meishan Iron and Steel Company will have a small contribution to the hourly, daily and annual concentration of SO2 and PM10 in the whole assessed area and each assessment point. After the intended project is put into production, the impact that the dust generated by Meishan Iron and Steel Company exerts on the quality of atmospheric environment will be significantly reduced. The impact of SO2 and PM10 on the quality of atmospheric environment is basically same as the current projects does. The change range is

134

below 2% of standard value. The impact of NO2 is net increase, because the contribution concentration is small and the background concentration is low, and the superposition of these two still meets the requirement of Grade 2 environmental quality. The daily average emission concentration of characteristic pollutants in this project has no much impact on the ambient environmental quality at boundary. 8.3.6 Assessment conclusions on the current status of water environmental quality and impact analysis (1) At present, the water quality at each monitoring section in Nanjing’s Banqiao Section of the Changjiang River is good and better than two years ago. It can reach the requirement of Class II standard as defined in the Environmental Quality Standards for Surface Water (GB3838-2002). (2) After the intended project is completed, Meishan Iron and Steel Company (including Meishan Chemical Branch) will significantly reduce the amount of discharged wastewater, totally reduce the amount of discharged CODcr by 1630.5t/a, and lower CODcr concentration at the section 1400m (water intake) down West Discharge Outlet of Meishan Iron and Steel Company by about 0.01 mg/L, for although the amount of discharged pollutants is reduced significantly, the flow of the Changjiang River is very big, the effect of concentration reduction is limited and the water quality in this section of the river will still maintain current level. 8.3.7 Assessment conclusions on the current status of sound environmental quality and impact (1) Assessment conclusions on the current status of sound environmental quality The noise level at boundary of Meishan Iron & Steel Company is 46.8-69.5dB (A) in the daytime and 42.5-63.9 dB(A) at night. The noise at boundary exceeds specified limit in a number of monitoring points, but only at four night monitoring points, the excess of specified limit is caused by production noise, which are 6#, 11#, 12# and 19# monitoring points. After the intended project is completed, there is no residential area affected, and it won't cause much impact on environment. The intended project will, based on the principle of pushing ahead old by new, take appropriate noise control measures to ensure day and night noise at boundary reaches standard. The environmental noise at 21#, 22#, 23# and 24# sensitive points is lower than the standard value for Class 2 area during both day and night. The surrounding noise environment is good. (2) Conclusions on impact analysis of acoustic environmental quality After the intended project is put into production, the equipment noise may have certain impact on each monitoring point. The superposed value will increase slightly. But the forecast day and night noise values at boundary all meet the requirement of assessment standard. Moreover, after the sanitation protection distance is determined, the noise won’t affect the residential areas and villages near the boundary.

135

8.3.8 Conclusions on analysis of solid waste discharge and impact The dust recovered by the dust collection system of the intended project is coal or ferric particles. It is nontoxic and all reused in production. BF granulating slag, converter slag and continuous casting mill scale are all subject to comprehensive utilization. The slag and residue solution discharged during gas purification are all directly reused in production and not discharged to outside, so they won’t pollute the environment. 8.3.9 Analysis of environmental impact in construction period During construction of the project, the construction activities will inevitably create environmental impact, mainly including the environmental impact from waste gas, dust, noise, solid waste and wastewater. According to the analysis of the construction characteristics of the project, the environmental impact in construction period is short-term, recoverable and local environmental impact. 8.3.10 Analysis of environmental risks Among the main production raw material and products of this project, benzene and gas are inflammable and explosive; ammonia, and NaOH and HCl are highly corrosive. The storage, transport and use of raw material have potential environmental risk. Effective and strict risk control measures must be taken from the perspectives of technology and management to nip it in the bud. During production, abnormal operation or damage of environmental protection facilities will result in excessive discharge of pollutants and affect environmental quality. This assessment puts forth disaster plan and emergency measures for sudden accidents and provides countermeasures for failure of environmental protection facilities. In a word, even if risk accident occurs, by taking the above preventive measures, it can still be limited to production site and effectively controlled and won’t spread out of the factory and to neighboring enterprises. 8.3.11 Analysis conclusions on economic benefit of environmental impact (1) Investment in environmental protection The total investment of this project is RMB19,805.39 million, including RMB17,309.64 million of fixed asset investment, and RMB292.20 million of working capital. Among the investment in engineering construction, the investment in environmental protection amounts to RMB1.864 billion, accounting for 9.4% of the investment in engineering construction. (2) Economic benefit of the investment in environmental protection The environmental protection facilities of the intended project can recover all kinds of usable solid waste and recover and utilize water resources, thus reducing the consumption of raw material and the emission of pollutants. They have obvious economic benefit. If the industrial wastewater generated in the whole company is treated and reused, 27.156 mt/a of fresh water can be saved. (3) Environmental benefit of the investment in environmental protection The environmental benefit generated by environmental protection facilities is mainly reflected

136

by reduced discharge of pollutants. It will play a positive role in improving the atmospheric quality and ecological environment inside and near Meishan Iron and Steel Company and reducing the impact on the water quality in the Changjiang River. (4) Social benefit of the investment in environmental protection The social benefit of the investment in environmental protection can hardly be assessed with money, but it is remarkable and mainly reflected in the following aspects: reducing pollutant discharge, helping improve people’s life quality and health, and help the development of local economy and the comprehensive utilization of water resources as well as the sustainable development of the enterprise. To summarize, in view of economic benefit of environmental impact, the intended project’s investment in environmental protection has good economic benefit as well as sound environmental and social benefit. 8.3.12 Public participation and conclusions (1) During this public participation, 404 copies of “Form of Solicitation for Public Opinions on Environmental Protection of Construction Projects in Jiangu” were distributed and all were returned. (2) In the suggestion and requirement column, most respondents gave their own suggestion and requirement. 314 of the 404 people filled out this column, with a participation rate of 78% which is rare in the past survey of public participation, indicating people in the area have a very strong sense of participation and they care about environmental protection, their own interest and social development and progress. (3) Among the respondents, 82 firmly support this project, 300 conditionally support it, 14 don’t care it and 8 oppose it. (4) Among the eight opposers, 4 wrote reasons and 4 not. The requirement and suggestion written by 3 persons in the suggestion column indicate that this project has air, water and noise pollution. We believe this is a proper act for protecting their environmental rights and interests. Although the opposers are a minority, construction unit shall give sufficient attention to their voices. 8.4 General conclusion (1) The intended project complies with the Development Policy for Iron and Steel Industry. a. Building area of sintering machine>180m2; height of coke oven carbonization chamber≥6m; effective area of BF≥1000m3; nominal volume of converter≥120t; nominal capacity of electric furnace≥70t. b. Pulverized coal injection unit, oven-front dust trap and residual pressure generator unit are built to support BF; CDQ, dust collection unit for coal charging and coke pushing is built to support coke oven; converter gas recovery unit is built synchronously to support converter. c. In the intended project, the overall energy consumption per ton of steel is 0.683t of standard coal, the consumption of fresh water per ton of steel is 4.7 tons, meeting the

137

requirement of clean production, and pollutant discharge indexes meet the requirement of environmental protection standard. d. The remaining gas is used for heat and power generation, meeting the requirement for saving energy and increasing the production of self-provided power. e. Meishan Iron and Steel Company is subordinate to Baosteel Co., Ltd. and is within the scope that industrial policy encourages it to increase scale to a proper extent and adjust industrial mix. f. The project realizes the goal of increasing output and reducing sewage. g. External conditions such as: ore, coke, water supply, and transport are possessed and can fully meet the production demand of this project. (2) The intended project complies with Nanjing urban master plan. The construction of the Product Matrix and Process Equipment Upgrading and Technical Transformation Project of Baosteel Meishan Iron and Steel Company is implemented on the acquired land at the neighborhood of the current premises. The land has been included into urban master plan. Procedures for land use are proceeding. Demolition and relocation plan is being implemented by government department. This project complies with Nanjing urban master plan. (3) The intended project complies with Nanjing environmental protection planning It is indicated in the Nanjing Environmental Protection Plan for Riverfront Development: industries with serious water pollution shall be arranged in the downstream of a city and water source, and industry with serious air pollution shall be arranged at leeward so far it is possible. The construction site of this project meets this requirement. (4) The construction of the intended project meets the requirement of up-to-standard discharge and total amount control Definite control measures are provided for every waste gas emission source in this intended project and the waste gas is emitted only after it reaches emission standard; a small amount of wastewater is led into the general sewage treatment plant via pipeline network. After treated, it enters the company’s reuse water system. The amount of wastewater discharged by the company is reduced significantly and all discharged wastewater reaches Grade 1 standard. After the intended project is put into production, the emission amount of main pollutants in waste gas: SO2 17243t/a, and smoke gas 6057t/a, meeting the requirement set by Nanjing Environmental Protection Bureau on the total amount control index of Meishan Iron and Steel

Company (smoke gas: 10600 t/a, SO2: 19000+2000t/a). So it can be seen: after this project is completed, the discharge of pollutants will meet the requirement of up-to-standard discharge and total amount control. (5) The site of the intended project is basically feasible. (6) The construction of the intended project meets the requirement of clean production 138

In consultation of the “cleaner production standard” for iron and steel industry (draft for comment), after this project is completed, the clean production level of Meishan Iron and Steel Company can basically reach Grade 1 level. (7) After the Product Matrix and Process Equipment Upgrading and Technical Transformation Project of Meishan Iron and Steel Company is completed and put into production, Meishan Iron and Steel Company will adopt a series of environmental protection measures. After the project is completed, the company will meet the requirement of total amount control as ratified by Nanjing Environmental Protection Bureau. (8) After the intended project is completed, the emission amount of smoke gas will be reduced significantly, compared to the existing projects. The reduction amount is 4631t/a, the reduction amount of SO2 is 1325t/a and the reduction amount of industrial wastewater is 15.41832 mt/a. All these lighten Meishan Iron and Steel Company’s impact on local environmental quality. The noise impact on surrounding environment is in an acceptable range. In a word, after the intended project is completed, the impact of Meishan Iron and Steel Company on surrounding environmental quality will be alleviated. (9) General conclusion on the assessment of the construction of the intended project The construction of the intended project complies with national industrial development policy, Nanjing urban master plan, Nanjing environmental protection plan and the requirement of environmental quality. The assessment index for pollutant discharge meets the requirement of up-to-standard discharge and total amount control. The site selected is basically feasible. Therefore, as long as the Product Matrix and Process Equipment Upgrading and Technical Transformation Project of Meishan Iron and Steel Company earnestly implements all kinds of pollution control measures set forth in report, and establishes and implements ISO14001 environmental management system, the construction of this project is feasible in terms of environmental protection. 8.5 Suggestions (1) In order to meet total amount control index, while the intended project is completed and put into production, the “pushing ahead old by new” environmental protection project shall be carried out. Meishan Iron and Steel Company shall work out practical and feasible control solutions and make active effort to implement them to ensure “three simultaineouses” acceptance inspection is carried out as per the time specified in the report. (2) By now, the reuse water plant of Benxi Iron & Steel Corporation has been built up. Reuse water and fresh water are mixed in the service reservoir and then supplied to each process step through one pipeline. The effect is good. In contrast, the supply of reuse water currently being designed by Meishan Iron and Steel Company is separated from the supply of fresh water. It needs two pipelines to supply water to each plant and has no advantage in management and construction cost, so we suggest Meishan Iron and Steel Company carefully study the approach of Benxi Iron & Steel Corporation, learn from strong points to offset its weakness and adopt more reasonable and economical water supply method. In addition, after treated in sewage treatment station, 74% of industrial water is reused. This

139

ratio can be further increased, thus further reducing the consumption of fresh water. (3) Ensure all phenol-cyanogen wastewater is treated to reach standard and then is reused without discharge. The reuse ways include BF slag flushing, sinter pelletization, ash flushing in power plant, and BF gas cleaning. Meanwhile, a buffer reservoir shall be built to cope with emergent equipment failure. When it is used to flush slag and ash, the sump and ash flushing tank should be seepage and leakage resistant to avoid soil and underground water pollution. (4) Among the existing facilities, 2×130m2 sintering machines and 2×1250m3 BFs have been in service for more than 30 years. They are aged and near to the end of their life, have such problems as low production efficiency, high energy consumption and backward environmental protection facilities and can’t adapt to the requirement of cyclic economy and sustainable development. For this reason, it is suggested to reasonably eliminate them in the “11th Five-Year Plan” period and develop the production facilities for pre-ironmaking system of Meishan Iron and Steel Company towards the directions of scale, intensiveness and efficiency to make the configuration of pre-ironmaking system more reasonable. (5) In the area within the sanitation protection distance of this project and beyond the boundary of Meishan Iron and Steel Company, effort shall be made to prevent the unapproved construction of residential points, or purchase the residence by Meishan Iron and Steel Company and use the area for greening and landscaping or as reserve land. (7) It is suggested that Nanjing Environmental Protection Bureau exercises strict environmental supervision and examination on Meishan Iron and Steel Company and ensure the control measures determined in the report are implemented on schedule.
