http://www.hydrocarbonprocessing.com Hydrocarbon Processing An innovative process for simultaneously producing high-purity benzene and U.S.-grade gasoline from FCC C<sub>6</sub> heartcut https://hydrocarbonprocessing.com/magazine/2024/march-2024/process-optimization/an-innovative-process-for-simultaneously-producing-high-purity-benzene-and-us-grade-gasoline-from-fcc-csub6sub-heartcut/ Mobile Source Air Toxics (MSAT) II regulations restrict the average benzene level in gasoline sold in the U.S. to 0.62 vol%. In India and in several other countries, benzene in gasoline is presently restricted to 1 vol%. Fluid catalytic cracking (FCC) gasoline contributes to nearly 10%–20% of the gasoline pool in a typical refinery. Executive Viewpoint: FCC propylene production, catalysts technologies and new solutions https://hydrocarbonprocessing.com/magazine/2024/march-2024/columns/executive-viewpoint-fcc-propylene-production-catalysts-technologies-and-new-solutions/ Welcome to Hydrocarbon Processing’s new Executive Series. In this enhanced video platform, the editors speak with the operators and technology leaders and suppliers that are optimizing the global hydrocarbon processing industry (HPI). A novel process for the oxidative dehydrogenation of ethane to produce ethylene and acetic acid https://hydrocarbonprocessing.com/magazine/2024/march-2024/special-focus-petrochemical-technologies/a-novel-process-for-the-oxidative-dehydrogenation-of-ethane-to-produce-ethylene-and-acetic-acid/ The authors’ company has developed a commercial chemical processa for the oxidative dehydrogenation of ethane (ODH-E). By means of a heterogeneous catalyst, ethane and oxygen are selectively converted into ethylene and acetic acid, which, after separation and purification, are provided in polymer-grade and glacial quality, respectively. Digital Feature: A novel process to help refinery operations comply with the U.S. Renewable Fuel Standard https://hydrocarbonprocessing.com/news/2024/02/digital-feature-a-novel-process-to-help-refinery-operations-comply-with-the-us-renewable-fuel-standard/ This article, exclusive to Hydrocarbon Processing, details a novel refinery processing technology that enables refineries to produce fuels that adhere to the U.S. RFS. Plastic pyrolysis oils as feedstock for steam crackers: Opportunities and challenges—Part 2 https://hydrocarbonprocessing.com/magazine/2024/february-2024/petrochemical-technologies/plastic-pyrolysis-oils-as-feedstock-for-steam-crackers-opportunities-and-challenges-part-2/ Plastic waste is a worldwide challenge. To reduce its carbon dioxide (CO2) footprint, the plastics industry is striving to increase circularity by using plastic pyrolysis oils (pyoils) from waste plastics as steam cracker feedstock. Practical examples and considerations in designing emergency depressurizing systems https://hydrocarbonprocessing.com/magazine/2024/february-2024/environment-and-safety/practical-examples-and-considerations-in-designing-emergency-depressurizing-systems/ Process operating facilities typically process large inventories of gas and volatile hydrocarbon liquids at high pressures, which have the potential of posing major hazards during emergency incidents—such as fire, loss of containment or operating excursion. Plastic pyrolysis oils as feedstock for steam crackers: Opportunities and challenges—Part 1 https://hydrocarbonprocessing.com/magazine/2024/january-2024/special-focus-sustainability-and-the-energy-transition/plastic-pyrolysis-oils-as-feedstock-for-steam-crackers-opportunities-and-challenges-part-1/ Plastic waste is a global challenge. Today, only a minimal amount of plastic waste is recycled, mostly mechanically. Innovative approach to accelerating the startup of a gasoline block and associated units at Saudi Aramco’s Jazan refinery complex https://hydrocarbonprocessing.com/magazine/2024/january-2024/process-optimization/innovative-approach-to-accelerating-the-startup-of-a-gasoline-block-and-associated-units-at-saudi-aramco-s-jazan-refinery-complex/ This article elaborates on the startup of a refinery’s heavy naphtha reforming unit with an alternative approach to the initial unit design, including an evaluation of several startup techniques to ensure the adequacy and practicality of the selected option. Izmit FCCU revamp https://hydrocarbonprocessing.com/magazine/2024/january-2024/process-optimization/izmit-fccu-revamp/ Tüpraş utilizes proprietary fluid catalytic cracking unitsa (FCCUs) at its Izmit and Izmir refineries. The Izmit unit was designed in 1968 and started up in 1972 with a side-by-side style reactor/regenerator. Executive Viewpoint: A lifecycle assessment on chemically recycling plastics: A conversation with Neste’s Maiju Helin https://hydrocarbonprocessing.com/magazine/2024/january-2024/columns/executive-viewpoint-a-lifecycle-assessment-on-chemically-recycling-plastics-a-conversation-with-neste-s-maiju-helin/ HP spoke with Maiju Helin, Head of Sustainability and Regulatory Transformation Renewable Polymers and Chemicals, Neste, regarding Neste’s lifecycle assessment report on chemically recycling waste plastic.
