摘要： The liquid hydrocarbon stream including COS is introduced via line 1 into membrane contactor CM to be placed in contact, through membrane M, with the aqueous alkanolamine solution arriving via line 3. 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 line 2. The aqueous solution containing COS is sent via line 4 to zone R to be regenerated. The compounds released during regeneration, particularly COS and COS-derived products, are evacuated from zone R via line 5. The regenerated aqueous alkanolamine solution is recycled via line 3 into membrane contactor CM.

摘要： The gaseous effluent flowing in through line 1 is contacted in absorption zone ZA with the liquid absorbent solution flowing in through line 9. The gaseous effluent depleted in acid compounds is discharged through line 2. The absorbent solution laden with acid compounds is discharged through line 3. The absorbent solution once laden with acid compounds comprises two phases: a first phase poor in acid compounds and a second phase rich in acid compounds. The two phases are separated in zone ZS. The first phase is recycled through lines 5 and 9 to absorption zone ZA. The second phase is fed through line 4 into regeneration zone ZR. In zone ZR, the acid compounds are separated from the absorbent solution. The acid compounds are discharged through line 7. The regenerated absorbent solution is recycled through lines 6 and 9 to zone ZA.

摘要： The fumes flowing in through line 1 are contacted in column C1 with a solvent, at low vapour pressure, absorbing the carbon dioxide. The solvent laden with carbon dioxide is regenerated by distillation in column C2. In order to improve the regeneration operation, a gas is injected through line 11 into column C2 so that this gas carries along the carbon dioxide contained in the solvent. The carbon dioxide-rich gaseous effluent obtained at the top of column C2 can be liquefied by compression and cooling, then stored in surge tank R, which allows its transportation and possibly underground sequestration.
