What Octane Rating of Gasoline Should I Use? By: Ralph Seekins
What Octane Rating of Gasoline Should I use? By: Ralph Seekins Question: I recently bought my first new car, a Ford Focus. I’ve been told I should use premium fuel because it’s better for my car. However my owner’s manual says to use 87 octane regular gasoline. With today’s gas prices, is there really any benefit to using premium? Answer: Your owner’s manual is right. Your vehicle’s engine was designed and built to run on unleaded 87 octane regular gas. However, if your advisor is from my generation, there was a time when vehicles had carburetors (my grandkids call it the “olden days”) that premium (higher octane rated) gas did have some benefit over regular gas. Octane rating is a measure of the resistance of gasoline to detonation in internal combustion engines that use spark plugs to ignite the air/gas mixture. The higher the octane rating, the lower the chance for a too-early explosion – called engine spark knock. Higher performance engines operate with a higher compression ratio (the air/gas mixture is compressed into a smaller area thereby causing more pressure and heat) so they require a slower burning (higher octane) fuel. That’s not the case for your car or for most modern cars on the highway today. All manufacturers now utilize a number of sensors, an on-board computer and fuel injectors to accurately control the air/gas mixture under all imaginable temperature and environment conditions. These components work together to make sure that every time the cylinders in your car’s engine fire the fuel is completely burned. -
APPENDIX M SUMMARY of MAJOR TYPES of Carfg2 REFINERY
APPENDIX M SUMMARY OF MAJOR TYPES OF CaRFG2 REFINERY MODIFICATIONS Appendix M: Summan/ of Major Types of CaRFG2 Refinery Modifications: Alkylation Units A process unit that combines small-molecule hydrocarbon gases produced in the FCCU with a branched chain hydrocarbon called isobutane, producing a material called alkylate, which is blended into gasoline to raise the octane rating. Alkylate is a high octane, low vapor pressure gasoline blending component that essentially contains no olefins, aromatics, or sulfur. This plant improves the ultimate gasoline-making ability of the FCC plant. Therefore, many California refineries built new or modified existing units to increase alkylate production to blend and to produce greater amounts of CaRFG2. Alkylate is produced by combining C3, C4, and C5 components with isobutane (nC4). The process of alkylation is the reverse of cracking. Olefins (such as butenes and propenes) and isobutane are used as feedstocks and combined to produce alkylate. This process enables refiners to utilize lighter components that otherwise could not be blended into gasoline due to their high vapor pressures. Feed to alkylation unit can include pentanes from light cracked gasoline treaters, isobutanes from butane isomerization unit, and C3/C4 streams from delayed coking units. Isomerization Units - C4/C5/C6 A refinery that has an alkylation plant is not likely to have exactly enough is-butane to match the proplylene and butylene (olefin) feeds. The refiner usually has two choices - buy iso-butane or make it in a butane isomerization (Bl) plant. Isomerization is the rearrangement of straight chain hydrocarbon molecules to form branched chain products or to convert normal paraffins to their isomer. -

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. -

Transition Metal Hydrides That Mediate Catalytic Hydrogen Atom Transfers
Transition Metal Hydrides that Mediate Catalytic Hydrogen Atom Transfers Deven P. Estes Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2014 © 2014 Deven P. Estes All Rights Reserved ABSTRACT Transition Metal Hydrides that Mediate Catalytic Hydrogen Atom Transfers Deven P. Estes Radical cyclizations are important reactions in organic chemistry. However, they are seldom used industrially due to their reliance on neurotoxic trialkyltin hydride. Many substitutes for tin hydrides have been developed but none have provided a general solution to the problem. Transition metal hydrides with weak M–H bonds can generate carbon centered radicals by hydrogen atom transfer (HAT) to olefins. This metal to olefin hydrogen atom transfer (MOHAT) reaction has been postulated as the initial step in many hydrogenation and hydroformylation reactions. The Norton group has shown MOHAT can mediate radical cyclizations of α,ω dienes to form five and six membered rings. The reaction can be done catalytically if 1) the product metalloradical reacts with hydrogen gas to reform the hydride and 2) the hydride can perform MOHAT reactions. The Norton group has shown that both CpCr(CO)3H and Co(dmgBF2)2(H2O)2 can catalyze radical cyclizations. However, both have significant draw backs. In an effort to improve the catalytic efficiency of these reactions we have studied several potential catalyst candidates to test their viability as radical cyclization catalysts. I investigate the hydride CpFe(CO)2H (FpH). FpH has been shown to transfer hydrogen atoms to dienes and styrenes. I measured the Fe–H bond dissociation free energy (BDFE) to be 63 kcal/mol (much higher than previously thought) and showed that this hydride is not a good candidate for catalytic radical cyclizations. -
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.

Energy and the Hydrogen Economy
Energy and the Hydrogen Economy Ulf Bossel Fuel Cell Consultant Morgenacherstrasse 2F CH-5452 Oberrohrdorf / Switzerland +41-56-496-7292 and Baldur Eliasson ABB Switzerland Ltd. Corporate Research CH-5405 Baden-Dättwil / Switzerland Abstract Between production and use any commercial product is subject to the following processes: packaging, transportation, storage and transfer. The same is true for hydrogen in a “Hydrogen Economy”. Hydrogen has to be packaged by compression or liquefaction, it has to be transported by surface vehicles or pipelines, it has to be stored and transferred. Generated by electrolysis or chemistry, the fuel gas has to go through theses market procedures before it can be used by the customer, even if it is produced locally at filling stations. As there are no environmental or energetic advantages in producing hydrogen from natural gas or other hydrocarbons, we do not consider this option, although hydrogen can be chemically synthesized at relative low cost. In the past, hydrogen production and hydrogen use have been addressed by many, assuming that hydrogen gas is just another gaseous energy carrier and that it can be handled much like natural gas in today’s energy economy. With this study we present an analysis of the energy required to operate a pure hydrogen economy. High-grade electricity from renewable or nuclear sources is needed not only to generate hydrogen, but also for all other essential steps of a hydrogen economy. But because of the molecular structure of hydrogen, a hydrogen infrastructure is much more energy-intensive than a natural gas economy. In this study, the energy consumed by each stage is related to the energy content (higher heating value HHV) of the delivered hydrogen itself. -
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. -
Thermal Conductivity Correlations for Minor Constituent Fluids in Natural
Fluid Phase Equilibria 227 (2005) 47–55 Thermal conductivity correlations for minor constituent fluids in natural gas: n-octane, n-nonane and n-decaneଝ M.L. Huber∗, R.A. Perkins Physical and Chemical Properties Division, National Institute of Standards and Technology, Boulder, CO 80305, USA Received 21 July 2004; received in revised form 29 October 2004; accepted 29 October 2004 Abstract Natural gas, although predominantly comprised of methane, often contains small amounts of heavier hydrocarbons that contribute to its thermodynamic and transport properties. In this manuscript, we review the current literature and present new correlations for the thermal conductivity of the pure fluids n-octane, n-nonane, and n-decane that are valid over a wide range of fluid states, from the dilute-gas to the dense liquid, and include an enhancement in the critical region. The new correlations represent the thermal conductivity to within the uncertainty of the best experimental data and will be useful for researchers working on thermal conductivity models for natural gas and other hydrocarbon mixtures. © 2004 Elsevier B.V.
