ABSTRACT:
The liquid hydrocarbon stream including COS is introduced via line1into membrane contactor CM to be placed in contact, through membrane M, with the aqueous alkanolamine solution arriving via line3.The 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 line2.The aqueous solution containing COS is sent via line4to zone R to be regenerated. The compounds released during regeneration, particularly COS and COS-derived products, are evacuated from zone R via line5.The regenerated aqueous alkanolamine solution is recycled via line3into membrane contactor CM.
