The liquid hydrocarbon stream including COS is introduced via lineinto membrane contactor CM to be placed in contact, through membrane M, with the aqueous alkanolamine solution arriving via lineThe COS contained in the hydrocarbon stream is absorbed by the aqueous alkanolamine solution. The liquid hydrocarbons from which the COS has been removed are evacuated from CM via lineThe aqueous solution containing COS is sent via lineto zone R to be regenerated. The compounds released during regeneration, particularly COS and COS-derived products, are evacuated from zone R via lineThe regenerated aqueous alkanolamine solution is recycled via lineinto membrane contactor CM.

Method for eliminating the carbonyl sulfide contained in a liquid hydrocarbon stream

The invention relates to a process, including removal of resins, for the treatment of a hydrocarbon charge, at least 80% of the compounds of which have a boiling point which is above or equal to 340&#xb0; C., in which process:

Method for treating a hydrocarbon feedstock including resin removal

For desulfurization of a hydrocarbon-containing feedstock, at least one stage for selective hydrogenation of diolefins present in the initial hydrocarbon feedstock, in the presence of a catalyst of group VIII of the period table, and a stage for extraction by a solvent of the resultant hydrogenated fraction under conditions that provide at least two fractions:

Process for desulfurization comprising a stage for selective hydrogenation of diolefins and a stage for extraction of sulfur-containing compounds
