Honeywell UOP is introducing an expanded portfolio of new hydrotreating catalysts used to remove impurities and contaminants from petroleum and other refining feedstocks to produce cleaner-burning gasoline and diesel that meets new global emissions regulations.
Asahi Kasei Mitsubishi Chemical Ethylene Corp.’s naphtha cracker in Mizushima has been restarted after production was suspended in July due to a malfunction in its refrigeration system.
A number of conversion processes, both hydrogen-addition-based and carbon-rejection-based, crack heavy oil into lighter hydrocarbon products.
Isomerate is useful because it is paraffinic and contains no benzene, aromatics or sulfur. This pentane and hexane fraction of crude oil is known as light naphtha. The main objective of reactions is to increase the research octane number (RON) of the components. Decreasing fuel consumption without changing the product RON of isomerization units is discussed here.
Improving profits and reducing costs remain priorities for owner/operators and management.
US product markets weakened despite unseasonably strong gasoline demand, and the gasoil crack spread hit the lowest level seen in more than five years, under pressure from increasing supplies amid thin demand due to warmer winter weather.
Asian margins showed a strong recovery due to higher winter heating fuel demand, supporting middle distillate crack spreads.
A refinery with an active crude selection strategy encompassing dedicated staff, preapproval of all new crudes and an updated crude acceptance window can gain $0.5/bbl–$1/bbl vs. a more passive strategy.
The hydrocarbon processing industry (HPI) has changed significantly with an abundance of available discounted crude oils, a rise in markets served beyond the traditional local or regional demands, and a renewed focus on being both competitive and profitable while complying with ever-changing regulations.
