The results demonstrate that the wetting of rough surfaces of ceramic samples and coatings by liquid Ge is significantly poorer than that of the smooth surface of quartz glass. The contact angle of polished glass is ~100°, and that of the ceramics and coatings increases from 112° to 137° as the total impurity content of the material decreases from 0.120 to 1 × 10–3 wt %. Using experimental contact angle data, we calculated the work of adhesion of molten Ge to the materials studied. -
Refining Crude Oil
REFINING CRUDE OIL New Zealand buys crude oil from overseas, as well as drilling for some oil locally. This oil is a mixture of many hydrocarbons that has to be refined before it can be used for fuel. All crude oil in New Zealand is refined by The New Zealand Refining Company at their Marsden Point refinery where it is converted to petrol, diesel, kerosene, aviation fuel, bitumen, refinery gas (which fuels the refinery) and sulfur. The refining process depends on the chemical processes of distillation (separating liquids by their different boiling points) and catalysis (which speeds up reaction rates), and uses the principles of chemical equilibria. Chemical equilibrium exists when the reactants in a reaction are producing products, but those products are being recombined again into reactants. By altering the reaction conditions the amount of either products or reactants can be increased. Refining is carried out in three main steps. Step 1 - Separation The oil is separated into its constituents by distillation, and some of these components (such as the refinery gas) are further separated with chemical reactions and by using solvents which dissolve one component of a mixture significantly better than another. Step 2 - Conversion The various hydrocarbons produced are then chemically altered to make them more suitable for their intended purpose. For example, naphthas are "reformed" from paraffins and naphthenes into aromatics. These reactions often use catalysis, and so sulfur is removed from the hydrocarbons before they are reacted, as it would 'poison' the catalysts used. The chemical equilibria are also manipulated to ensure a maximum yield of the desired product. -
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. -
Concept Papers for Changes to Rule 9-1 -- Refinery Fuel Gas Sulfur
Draft: 05‐14‐15 Appendix C: Concept Paper for Changes to Rule 9‐1: Refinery Fuel Gas Sulfur Limits Rules to Be Amended or Drafted Regulation of refinery fuel gas (RFG) requires amendments to Air District Regulation 9, Rule 1, Sulfur Dioxide. Goals The goal of this rulemaking is to achieve technically feasible and cost‐effective sulfur dioxide (SO2) emission reductions from RFG systems at Bay Area refineries. Background The lightest components of crude oil separated by a refinery’s atmospheric fractionator are methane and ethane, which are also the primary components of natural gas. At petroleum refineries, these products are not produced in marketable quantities, but are used as fuel in the numerous onsite steam generators and process heaters. When produced at a refinery, this product is called refinery fuel gas (RFG). Pipeline natural gas may be used as a supplemental fuel when needed to enhance the quality of RFG or when there is not enough RFG available. Unlike, pipeline natural gas, refinery fuel gas often contains significant quantities of sulfur that occur naturally in crude oil. When burned, these sulfur compounds are converted to SO2. Process and Source Description RFG can contain between a few hundred and a few thousand parts per million‐volume (ppmv) sulfur in the form of hydrogen sulfide (H2S), carbonyl sulfide (COS), and organic sulfur compounds, such as mercaptans. During combustion, the sulfur in all of these compounds will oxidize to form SO2, which is a criteria air pollutant and a precursor to particulate matter. Scrubbing with an amine or caustic solution can be effective at removing H2S and some acidic sulfur containing compounds, but is generally ineffective at removing nonacidic sulfur compounds. -

Liquefied Petroleum Gas (LPG)
Liquefied Petroleum Gas (LPG) Demand, Supply and Future Perspectives for Sudan Synthesis report of a workshop held in Khartoum, 12-13 December 2010 The workshop was funded by UKaid from the Department for International Development Cover image: © UNAMID / Albert Gonzalez Farran This report is available online at: www.unep.org/sudan Disclaimer The material in this report does not necessarily represent the views of any of the organisations involved in the preparation and hosting of the workshop. It must be noted that some time has passed between the workshop and the dissemination of this report, during which some important changes have taken place, not least of which is the independence of South Sudan, a fact which greatly affects the national energy context. Critically, following the independence, the rate of deforestation in the Republic of Sudan has risen from 0.7% per year to 2.2% per year, making many of the discussions within this document all the more relevant. Whilst not directly affecting the production of LPG, which is largely derived from oil supplies north of the border with South Sudan, the wider context of the economics of the energy sector, and the economy as a whole, have changed. These changes are not reflected in this document. This being said, it is strongly asserted that this document still represents a useful contribution to the energy sector, particularly given its contribution to charting the breadth of perspectives on LPG in the Republic of Sudan.

CCS: Applications and Opportunities for the Oil and Gas Industry
Brief CCS: Applications and Opportunities for the Oil and Gas Industry Guloren Turan, General Manager, Advocacy and Communications May 2020 Contents 1. Introduction ................................................................................................................................... 2 2. Applications of CCS in the oil and gas industry ............................................................................. 2 3. Conclusion ..................................................................................................................................... 4 Page | 1 1. Introduction Production and consumption of oil and gas currently account for over half of global greenhouse gas emissions associated with energy use1 and so it is imperative that the oil and gas industry reduces its emissions to meet the net-zero ambition. At the same time, the industry has also been the source and catalyst of the leading innovations in clean energy, which includes carbon capture and storage (CCS). Indeed, as oil and gas companies are evolving their business models in the context of the energy transition, CCS has started to feature more prominently in their strategies and investments. CCS is versatile technology that can support the oil and gas industry’s low-carbon transition in several ways. Firstly, CCS is a key enabler of emission reductions in the industries’ operations, whether for compliance reasons, to meet self-imposed performance targets or to benefit from CO2 markets. Secondly, spurred by investor and ESG community sentiment, the industry is looking to reduce the carbon footprint of its products when used in industry, since about 90% of emissions associated with oil and gas come from the ultimate combustion of hydrocarbons – their scope 3 emissions. Finally, CCS can be a driver of new business lines, such as clean power generation and clean hydrogen production. From the perspective of the Paris Agreement, however, the deployment of CCS globally remains off track. -

Managing Exposure to Benzene and Total Petroleum Hydrocarbons at Two Oil Refineries 1977–2014
International Journal of Environmental Research and Public Health Article Managing Exposure to Benzene and Total Petroleum Hydrocarbons at Two Oil Refineries 1977–2014 Tapani Tuomi *, Henna Veijalainen and Tiina Santonen Finnish Institute of Occupational Health (FIOH), Topeliuksenkatu 41 B, P.O. 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).
