CHANGES FROM LAST EDITION In the 2019 edition of this online data service the default data display is figures rounded to zero decimal places. However, from 2017 data onwards, further detail, up to the three decimal place level, is available where reported by the national administrations, upon selecting View > Decimals in the Menu bar. Please note that the constituent data summed to produce regional and flow aggregates may be reported at differing levels of precision. Therefore, care should be taken when using data for aggregated flows beyond the level of 0 decimal places. Data up to and including 2016 have been rounded to 0 decimal places. Please note that this may result in some rounding errors when comparing values for aggregates to the sum of their constituents. The file Coal Balance OECD retains 4 decimals throughout the time series. Note: Periods (.) are used to separate decimal places. Moreover, in the 2019 edition the list of import origins and export destinations was expanded. As a result quanti- ties may no longer appear in the other non-OECD geographical aggregates. Geographical coverage: Lithuania became the 36th OECD Member country in July 2018. Accordingly, Lithuania appears in the list of OECD Members and is included in the OECD zone aggregates for data starting in 1990. Prior to 1990, data for Lithuania are included in Former Soviet Union. From 2011 data onwards, France now includes Monaco, and the following overseas departments (Guadeloupe; French Guiana; Martinique; Mayotte; and Réunion); and excludes the overseas collectivities (New Caledonia; French Polynesia; Saint Barthélemy; Saint Martin; Saint Pierre and Miquelon; and Wallis and Futuna). Prior to 2011, France includes Monaco and excludes the following overseas departments and territories: Guadeloupe; French Guiana; Martinique; Mayotte and Réunion; New Caledonia; French Polynesia; Saint Barthélemy; Saint Martin; Saint Pierre and Miquelon; and Wallis and Futuna. South Africa joined as an Association country in November 2018. Accordingly, South Africa is now included in the IEA and Accession/Association countries aggregate in in the file Coal World Supply.

FLOW DEFINITIONS OECD, Coal Statistics (kt,TJ): COAL STATISTICS OECD.IVT WORLD, World Coal Supply: COAL WORLD SUPPLY.IVT Supply Flow Short name Definition Production INDPROD Refers to the quantities of fuels extracted or produced, calculated after any operation for removal of inert matter or impurities (e.g. sulphur from natural gas). For “other hydrocarbons” (shown with crude oil), production should include synthetic crude oil (including mineral oil extracted from bituminous minerals such as oil shale and tar sands, etc.). Production of secondary oil products represents the gross refinery output. Secondary coal products and gases represent the output from coke ovens, gas works, blast furnaces and other transformation processes. From other sources – OSCOAL Refers to both primary energy that has not been accounted for under coal production and secondary energy that has been accounted for in the production of another fuel. For example, under primary coal: recov- ered slurries, middlings, recuperated coal dust and other low-grade coal products that cannot be classified according to type of coal from which they are obtained; under gas works gas: natural gas, refinery gas, and LPG, that are treated or mixed in gas works (i.e. gas works gas produced from sources other than coal). From other sources – OSNATGAS Refers to both primary energy that has not been accounted for under natural gas production and secondary energy that has been accounted for in the production of another fuel. From other sources – oil OSOIL Refers to both primary energy that has not been accounted for under products production and secondary energy that has been accounted for in the production of another fuel. For example, under additives: benzol, alcohol and methanol produced from natural gas; under refinery feedstocks: backflows from the petrochemical industry used as re- finery feedstocks; under “other hydrocarbons” (included with crude oil): liquids obtained from coal liquefaction and GTL plants. INTERNATIONAL ENERGY AGENCY 8 - COAL INFORMATION: DATABASE DOCUMENTATION (2019 edition) Supply Flow Short name Definition From other sources – OSRENEW Refers to both primary energy that has not been accounted for under renewables production and secondary energy that has been accounted for in the production of another fuel. From other sources – OSNONSPEC Refers to both primary energy that has not been accounted for under not elsewhere specified production and secondary energy that has been accounted for in the production of another fuel. This flow is used if the source is not known. Imports IMPORTS Comprise the amount of fuels obtained from or supplied to other countries, whether or not there is an economic or customs union between the relevant countries. Coal in transit should not be included. Exports EXPORTS Comprise the amount of fuels obtained from or supplied to other countries, whether or not there

ISBN 978-88-95608-68-6; ISSN 2283-9216 DOI: 10.3303/CET1871065 An Empirical Study on Laboratory Coke Oven-based Coal Blending for Coking with Tar Residue Wenqiu Liu Hebei Energy College of Vocation and Technology, Tangshan 063004, China [email protected] Tar residue is the solid waste produced in coking plants or gas generators. Utilizing tar residue as additive in coal blending for coking is an effective approach for coal coking in our country, not only improving the yield and nature of coking products, but also realizing the recycling of tar residue. In this paper, tar residue is used as additive in coal blending for coking experiments, and combined with experiments on the crucible coke, small coke oven and industrial coke oven, the influences of the addition amount of tar residue on coke yield, coke reactivity and coke strength after reaction are further analyzed. As the experiment results reveal, compared to the experiment results of crucible coke and small coke ovens, the coke yield, coke reactivity and coke strength after reaction of industrial coke ovens are all bigger, leading to potential industrialization of coal blending for coking. Moreover, the influence of the amount of tar residue on the coal tar yield rate and gas yield is the same as that of coke reactivity and coke strength after reaction. 1. Introduction With the rapid development of economy, the fast growth of iron and steel industry has led China's coke industry to accomplish extraordinary achievements (Si et al., 2017).

  • Lignite Mining Development Strategy
    Energy Strat egy and P olicy of Kos ovo White Paper LIGNITE MINING DEVELOPMENT STRATEGY STATEM ENT OF PRINCIPL E Recognizing that lignite will remain the principal fuel for electricity generation in the long term, the use of indigenous coal is encouraged in an environmentally and economically responsible manner, as well as reclamation of lands previously disturbed by mining. BACKGROUND Lignite is of outstanding importance to electricity generation in Kosovo. It contributes to 97% of the total electricity generation, 3% being hydro based pow er generation. Considering all the potential sources for pow er generation in Kosovo, coal safely maintains its leading position. The Kosovo lignite mines are operated at one of the most favorable lignite RESOURCE deposits in Europe due to its geological conditions. With an average ADVANTAGE ! stripping ratio of 1.7 m3 of w aste to 1 ton of coal, coal production at Kosovo mines could supply very competitive fuel to the pow er plants, compared to Sufficient for electricity international fuel sources and energy prices. The total estimated generation in decades economically exploited resources of approx. 10,000 Mt represent one of the to come. richest lignite sources in Europe, w hich would allow ambitious pow er generation and expansion schemes in the forth coming decades. Coal supply can rise in correlation w ith increasing electricity consumption. Coal can be supplied w ith the highest degree of security and with predictable price levels. By this, Kosovo can take advantage of its large reserves and of its location in centre of South East Europe, w here lack of electricity is to be expected in the mid to long ter m period.

  • Coal Tar Pitch – Its Past, Present and Future in Commercial Roofing by Joe Mellott
    - 1 - Coal Tar Pitch – Its Past, Present and Future in Commercial Roofing By Joe Mellott Coal tar remains a desired and strong source of technology within the roofing industry, as innovative coal tar products significantly reduce associated health hazards and environmental impact. To help you better understand the role that coal tar continues to play in the commercial roofing market, this article will explore: • The history of coal tar • Its associated hazards • Hot and cold coal tar adhesive technologies • Modified coal tar pitch membrane technologies • Coal tar’s sustainability attributes A Brief History of Coal Tar In order to understand what coal tar pitch is, it’s important to understand its origins and refinement methods. Coal tar can be refined from a number of sources including coal, wood, peat, petroleum, and other organic materials. The tar is removed by burning or heating the base substance and selectively distilling fractions of the burned chemical. Distillation involves heating the substance to a point where different fractions of the substance become volatile. The fractions are then collected by condensing the fraction at a specific temperature. A base substance can be split into any number of fractions through distillation. A good example of industrial distillation is the oil refining process. Through distillation, crude oil can be separated into fractions that include gasoline, jet fuel, motor oil bases, and other specialty chemicals. Fractionation or distillation is a tried-and-true method for breaking a substance into different parts of its composition. One of the first uses of coal tar was in the maritime industry. Trees stumps were burned and the tar fractions were collected through distillation of the tar.

  • Lecture 32: Coke Production
    NPTEL – Chemical – Chemical Technology II Lecture 32: Coke production 32.1 Introduction Coal is used as fuel for electric power generation, industrial heating and steam generation, domestic heating, rail roads and for coal processing. Coal composition is denoted by rank. Rank increases with the carbon content and decreases with increasing oxygen content. Many of the products made by hydrogenation, oxidation, hydrolysis or fluorination are important for industrial use. Stable, low cost, petroleum and natural gas supplies has arose interest in some of the coal products as upgraded fuels to reduce air pollution as well as to take advantage of greater ease of handling of the liquid or gaseous material and to utilize existing facilities such as pipelines and furnaces. 32.2 Coking of coal Raw material is Bituminous coal. It appears to have specific internal surfaces in the range of 30 to 100m2/g. Generally one ton of bituminous coal produces 1400 lb of coke. 10 gallons of tar.
