ABSTRACT:
The gaseous feed flowing in through line1is contacted in contacting zone ZA with a liquid solvent flowing in through line2.The solvent comprises between 0.001% and 100% by weight of a liquid olefin. Contacting in zone ZA is carried out in the presence of an acid catalyst. The purified gaseous feed is discharged from zone ZA through line3.The sulfide-laden solvent is discharged through line4,then regenerated in unit RE. The regenerated solvent is recycled through lines7and2to zone ZA.
