1 Refinery and Petrochemical Processes
3 1 Refinery and Petrochemical Processes 1.1 Introduction The combination of high demand for electric cars and higher automobile engine effi- ciency in the future will mean less conversion of petroleum into fuels. However, the demand for petrochemicals is forecast to rise due to the increase in world popula- tion. With this, it is expected that modern and more innovative technologies will be developed to serve the growth of the petrochemical market. In a refinery process, petroleum is converted into petroleum intermediate prod- ucts, including gases, light/heavy naphtha, kerosene, diesel, light gas oil, heavy gas oil, and residue. From these intermediate refinery product streams, several fuels such as fuel gas, liquefied petroleum gas, gasoline, jet fuel, kerosene, auto diesel, and other heavy products such as lubricants, bunker oil, asphalt, and coke are obtained. In addition, these petroleum intermediates can be further processed and separated into products for petrochemical applications. In this chapter, petroleum will be introduced first. Petrochemicals will be intro- duced in the second part of the chapter. Petrochemicals – the main subject of this book – will address three major areas, (i) the production of the seven cornerstone petrochemicals: methane and synthesis gas, ethylene, propylene, butene, benzene, toluene, and xylenes; (ii) the uses of the seven cornerstone petrochemicals, and (iii) the technology to separate petrochemicals into individual components. 1.2 Petroleum Petroleum is derived from the Latin words “petra” and “oleum,” which means “rock” and “oil,” respectively. Petroleum also is known as crude oil or fossil fuel. It is a thick, flammable, yellow-to-black mixture of gaseous, liquid, and solid hydrocarbons formed from the remains of plants and animals. -
The Chemistry of Refining Crude Oil SPN#12
The Chemistry of Refining Crude Oil SPN LESSON #12 LEARNING OUTCOME: Students come to view energy from several viewpoints. They work with the processes of • Phase changes and the many energy transformations and transfers involved in that physical change; • chemical change and the energy it releases. LESSON OVERVIEW: The fractional distillation of crude oil is featured. This major fossil fuel of the modern age is viewed as an example of stored chemical energy. Alcohol and water are separated and recaptured by taking advantage of the differences in the two substances’ boiling points. The many components of crude oil are explored and students are introduced to organic chemical formulas, characteristics of changes in phases, and laboratory distillation procedures. GRADE-LEVEL APPROPRIATENESS: This Level II Physical Setting, technology education lesson is intended for students in grades 5–8. MATERIALS (per group) Safety goggles (per person) Lab apron (per person) Bunsen burner Ring stand with utility clamp Metal pan 3 medium test tubes Test tube rack Boiling chip 2-hole stopper 10 cm glass tubing with 90o bend Thermometer 15 mL of isopropyl alcohol–water mixture nyserda.ny.gov/School-Power-Naturally Stirring rod Graduated cylinder Grease pencil or marker 4 paper strips, 10 cm x 1 cm 60 cm rubber tubing SAFETY Students should be made familiar with proper laboratory safety procedures including the location of fire extinguishers, fire blankets, and safety showers (where available). Instruct students regarding the proper and safe use of Bunsen burners and matches, and stress the importance of keeping the volatile components of the fractional distillation away from the flame during the collection of distillates. -

WEF Nexus in Kenya, a Dynamic, Lower-Middle-Income ‘Frontier’ Economy That Is of Particular Interest for Several Reasons
The Water–Energy–Food Nexus in a Climate- Vulnerable, Frontier Economy: The Case of Kenya Report Prepared for the United Kingdom Department for International Development by the Sustainability Institute South Africa Disclaimer The author is grateful to the United Kingdom’s Department for International Development (DFID) for funding this research. All views expressed and any errors contained in the paper are the responsibility of the author, and should not be attributed to DFID. The Water–Energy–Food Nexus in a Climate- Vulnerable, Frontier Economy: The Case of Kenya Jeremy J. Wakeford, PhD1 March 2017 Abstract In recent years, the complex set of interdependencies among water, energy and food systems – the WEF nexus – has emerged as a central issue within the overlapping fields of sustainable development and climate change resilience. This paper conducts a case study of the WEF nexus in Kenya, a dynamic, lower-middle-income ‘frontier’ economy that is of particular interest for several reasons. First, the country is acutely vulnerable to climate change and variability, given its geographical location in East Africa and its dependence on largely rain-fed agriculture for nearly one-third of its GDP. Second, Kenya is poised to begin production of oil in 2017, which could have a substantial impact on the country’s ensuing development trajectory. Third, Kenya has been a leader within Africa in developing certain types of renewable energy, notably geothermal power. This paper explores the major global and national drivers affecting the WEF nexus in Kenya, such as a high rate of population expansion, rapid urbanisation and robust economic growth. -

Box 40, Työterveyslaitos, FI-00032 Helsinki, Finland; henna.veijalainen@ttl.fi (H.V.); tiina.santonen@ttl.fi (T.S.) * Correspondence: tapani.tuomi@ttl.fi; Tel.: +358-9-4747-2926 Received: 15 December 2017; Accepted: 18 January 2018; Published: 24 January 2018 Abstract: Air concentrations of and inhalation exposure to total petroleum hydrocarbons (TPH) and benzene was monitored separately at two oil refineries from 1977 to 2014. Prevention policies and control measures that may explain changes were surveyed. The aim was to evaluate how the application of of Occupational Health and Safety Assessment Series OHSAS 18001.04 principles as well as Environmental protection Agency EPA and European Oil Company Organisation for Environment, Health and Safety CONCAWE practices have influenced air concentrations. Benzene air concentrations declined in 11 of 17 units, six of which were associated with declining exposures. Benzene air concentrations declined across all units on average by 46%. This amounts to an average yearly decline of 1.7%. TPH air concentrations declined in 10 of 17 units, seven of which were associated with declining exposures. The average decline in TPH air concentrations was 49%, corresponding to 1.3% per year. As a result, average working day exposure in 10 of 17 units have declined significantly and today, benzene and TPH exposure in most units are well below 10% of the current Occupational Exposure Limit (OEL8h:s). -
Environmental, Health, and Safety Guidelines for Petroleum Refining
ENVIRONMENTAL, HEALTH, AND SAFETY GUIDELINES PETROLEUM REFINING November 17, 2016 ENVIRONMENTAL, HEALTH, AND SAFETY GUIDELINES FOR PETROLEUM REFINING INTRODUCTION 1. The Environmental, Health, and Safety (EHS) Guidelines are technical reference documents with general and industry-specific examples of Good International Industry Practice (GIIP).1 When one or more members of the World Bank Group are involved in a project, these EHS Guidelines are applied as required by their respective policies and standards. These industry sector EHS Guidelines are designed to be used together with the General EHS Guidelines document, which provides guidance to users on common EHS issues potentially applicable to all industry sectors. For complex projects, use of multiple industry sector guidelines may be necessary. A complete list of industry sector guidelines can be found at: www.ifc.org/ehsguidelines. 2. The EHS Guidelines contain the performance levels and measures that are generally considered to be achievable in new facilities by existing technology at reasonable costs. Application of the EHS Guidelines to existing facilities may involve the establishment of site-specific targets, with an appropriate timetable for achieving them. 3. The applicability of the EHS Guidelines should be tailored to the hazards and risks established for each project on the basis of the results of an environmental assessment in which site-specific variables— such as host country context, assimilative capacity of the environment, and other project factors—are taken into account. The applicability of specific technical recommendations should be based on the professional opinion of qualified and experienced persons. 4. When host country regulations differ from the levels and measures presented in the EHS Guidelines, projects are expected to achieve whichever is more stringent. -

Paradox of Deadwood Circular Bioeconomy in Kenya's Public Forests
sustainability Review Paradox of Deadwood Circular Bioeconomy in Kenya’s Public Forests Sylvester Ngome Chisika, Joon Park and Chunho Yeom * International School of Urban Sciences, University of Seoul, Seoul 02504, Korea; [email protected] (S.N.C.); [email protected] (J.P.) * Correspondence: [email protected] Abstract: With the rising demand for energy, the forest-based circular bioeconomy is gaining recog- nition as a strategy for sustainable production and consumption of forest resources. However, the forest-based bioeconomy remains underexplored from the perspective of deadwood conservation in public forests. While conducting a literature review and examining the case of Kenya, this study fills a gap in the literature to provide policy suggestions for sustainable forest resource utilization. The results from global literature indicate that deadwood performs essential social, economic, and environmental functions in the circular bioeconomy and sustainable development. Similarly, in Kenya, deadwood resources provide many socially beneficial bioproducts and services. However, the absence of scientific research and detailed guidelines for deadwood conservation may lead to the distortion of the ecological balance in public forests because of the legally sanctioned removal of deadwood, particularly firewood. Moreover, if the status quo remains, with approximately 70% of the growing population consuming deadwood for domestic use and the demand increasing, as shown by the current wood deficit in the country, there will be a major dilemma concerning whether to conserve deadwood for biodiversity or energy. Therefore, averting crisis and providing maximum deadwood value to society requires guidelines and comprehensive research in addition to a cultural Citation: Chisika, S.N.; Park, J.; and behavioral shift in energy consumption in a manner that embraces the forest-based circular Yeom, C. -

5.1 Petroleum Refining1
5.1 Petroleum Refining1 5.1.1 General Description The petroleum refining industry converts crude oil into more than 2500 refined products, including liquefied petroleum gas, gasoline, kerosene, aviation fuel, diesel fuel, fuel oils, lubricating oils, and feedstocks for the petrochemical industry. Petroleum refinery activities start with receipt of crude for storage at the refinery, include all petroleum handling and refining operations and terminate with storage preparatory to shipping the refined products from the refinery. The petroleum refining industry employs a wide variety of processes. A refinery's processing flow scheme is largely determined by the composition of the crude oil feedstock and the chosen slate of petroleum products. The example refinery flow scheme presented in Figure 5.1-1 shows the general processing arrangement used by refineries in the United States for major refinery processes. The arrangement of these processes will vary among refineries, and few, if any, employ all of these processes. Petroleum refining processes having direct emission sources are presented on the figure in bold-line boxes. Listed below are 5 categories of general refinery processes and associated operations: 1. Separation processes a. Atmospheric distillation b. Vacuum distillation c. Light ends recovery (gas processing) 2. Petroleum conversion processes a. Cracking (thermal and catalytic) b. Reforming c. Alkylation d. Polymerization e. Isomerization f. Coking g. Visbreaking 3.Petroleum treating processes a. Hydrodesulfurization b. Hydrotreating c. Chemical sweetening d. Acid gas removal e. Deasphalting 4.Feedstock and product handling a. Storage b. Blending c. Loading d. Unloading 5.Auxiliary facilities a. Boilers b. Waste water treatment c. Hydrogen production d.
