According to the latest KCC survey, annual hydrotreating catalyst demand in existing refineries in Kuwait is about 4,300 tonnes and expected to increase to about 16,000 by 2018 after the startup of both the new refinery and the Clean Fuels Project.
KBR in August 2009 got a contract to install four units at the refinery: a fluid catalytic cracker, a moderate-pressure hydrotreating plant, a diesel hydrotreating unit and a kerosene hydrotreating plant.
The project includes new processing units; including a 50,000 bpsd Crude Distillation Unit, a 33,500 bpsd Naphtha Hydrotreating Unit, a 22,500 bpsd Continuous Catalytic Reformer, a 10,500 bpsd Isomerisation Unit, and a 13,500 bpsd Kerosene Hydrotreating Unit.
They cover insights into fundamentals aspects from density function theory calculations and experimental surfaces sciences, preparing and characterizing industrial hydrotreating catalysis, and applications in producing clean fuels.
Its portfolio includes hydrocracking (ISOCRACKING), lubes hydroprocessing (ISODEWAXING and ISOFINISHING), ebullating bed resid hydrocracking (LC-FINING), and hydrotreating (ISOTREATING) technologies.
SEI started a feedstock hydrotreating facility, part of a reforming unit, on Aug.
First setting out the principles and tools, then citing case studies, they explore such topics as interfacial chemistry, impregnation and drying, deposition precipitation, clusters and immobilization, high-throughput experimentation, concepts for preparing zeolite-based catalysts, hydrotreating catalysts, and gold catalysts.
Francisco Montano, a Pemex spokesman in Mexico City, the capital, said the blast took place in one of the refinery's hydrotreating units, which remove sulfur from fuels under high pressure in the presence of explosive hydrogen gas.
Catalytic hydrotreating of two diesel distillates was carried out in a fixed-bed reactor using sulfided Co-Mo/[Al.
