Abstract: The present invention relates to the field of the extraction of sulphur-containing compounds such as the mercaptans, COS or H2S from a hydrocarbon-containing cut. This selective extraction is carried out by bringing the hydrocarbon-containing cut in liquid phase into contact with an alkaline solution, for example soda. The process according to the invention is an improved process for the regeneration of the alkaline solution, making it possible to reduce the quantity of alkaline solution required in the regeneration section.

Abstract: The present invention relates to the field of extraction of sulphur-containing compounds such as mercaptans, COS, H2S or CS2 from a hydrocarbon cut. This selective extraction is carried out by bringing the hydrocarbon cut in the liquid phase into contact with an alkaline solution, for example caustic soda. The process in accordance with the invention is an improved process for the regeneration of alkaline solution which can be used to reduce the quantity of alkaline solution necessary in the regeneration section.

Abstract: The present invention describes a process for the conversion of a heavy feed which can be used to improve the selectivity for middle distillate. The process employs a catalytic cracking unit followed by one or more units for the oligomerization of C2 to C9 olefins which can preferentially produce an additional cut termed the middle distillate. The light portion of the oligomerate produced which cannot be incorporated into the middle distillate cut is recycled to the FCC unit for cracking into light olefins which are returned to the oligomerization units as a supplement to the olefins of the feed in order to preferentially form heavy oligomerates which can be incorporated into the middle distillate cut.

Abstract: The present invention describes a process for catalytic cracking associated with a unit for amine treatment of regeneration fumes from the catalytic cracking unit, which process uses at least one counter-pressure turbine to operate the cracked gas compressor and/or the regenerative air blower which can be used to improve the CO2 balance by delivering a CO2 credit.

Abstract: This invention describes a process for mild hydrocracking of heavy hydrocarbon fractions of the vacuum distillate type or the deasphalted oil type with optimized thermal integration for the purpose of reducing greenhouse gas emissions.
