A multi-objective optimization study for an integrated oil refinery-petrochemical plant—Part 1
The study of the ideal integration of an oil refinery and an ethylene production facility has regained interest due to the rising costs of crude oil and its derivatives. This study proposes a multi-objective optimization approach that maximizes the net profit and production of ethylene and propylene in an integrated plant.
Why poultry fat is emerging as a solution for the renewable energy industry’s increasing need for diverse biofuel feedstocks
Throughout the past decade, biofuels production has significantly increased. Some of the largest growth in the sector has been with fuels that rely on lipids, such as vegetable oils and animal fats, as feedstock. This includes biodiesel, renewable diesel and sustainable aviation fuel (SAF).
A novel process to help refinery operations comply with the U.S. Renewable Fuel Standard
The Renewable Fuel Standard (RFS) is a regulation that requires refineries in the U.S. to output a certain percentage of their fuel from renewable sources, such as plants or animal waste. The U.S. Environmental Protection Agency (EPA) sets the minimum proportion of renewable fuel every year. The goal of the RFS is to reduce greenhouse gas emissions and dependence on fossil fuels.
Tackle operational challenges with FCC coprocessing applications
Refiners are actively developing new solutions to decarbonize their finished products—such as transportation fuels or commodity chemicals—as part of the energy transition. As a result, refiners are now exploring the co-feeding of alternative feedstocks, including renewable and recyclable crude oils, as a means of lowering the carbon footprint of their products.
Integrated column-reboiler system stress and flexibility analysis approach
In oil refineries and chemical plants, chemical reactions and separations take place in the distillation column.
Repsol: Renewable fuels are key to the transformation of the refining industry
Along with hydrogen production, the production of renewable fuels and gases from organic waste is one of the main examples of the transformation of the industry, which will generate employment and decarbonize the sector. Here, Repsol discusses several pathways the company is taking to produce additional renewable fuels, while decarbonizing operations.
Pemex is delivering only a fraction of feedstock to new Olmeca refinery
Mexican state energy company Pemex started sending 16,300 bpd of crude oil to its new Olmeca refinery this week, less than 5% of its total capacity, signaling another delay.
BASF expands its biomass balance portfolio for selected chemical intermediates
BASF will expand its biomass balance offering to include BMBCertTM 1,4-butanediol (BDO), tetra-hydrofuran (THF), polytetra¬hydrofuran (PolyTHF®) and 3-(di¬methyl¬amino)pro¬pyl¬amine (DMAPA).
Iran to boost gasoline, diesel production as new units go online
Jalil Salari, Managing Director, National Iranian Oil Refining and Distribution Company (NIORDC), provided an update on the country's refining units going online this year, which will significantly boost domestic gasoline and diesel production.
U.S. renewable diesel glut hits refiners' margins
A rush by U.S. fuel makers to recalibrate their plants to produce renewable diesel has created a supply glut for low-emissions biofuels, hammering profit margins for refiners and threatening to impede a young industry.
