Abstract: The mercaptan-laden natural gas is contacted with a mercaptan-adsorbing sieve T1. The mercaptan-rich gaseous effluent obtained upon regeneration of sieve T2 is then contacted with an olefin-containing liquid feed in the presence of an acid catalyst. Under suitable conditions, the mercaptans are absorbed in the liquid feed and they react with the olefins so as to form solvent-soluble sulfides. A solvent regeneration stage allows the capture agent to be recycled.

Abstract: The gaseous feed flowing in through line 1 is contacted in contacting zone ZA with a liquid solvent flowing in through line 2. 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 line 3. The sulfide-laden solvent is discharged through line 4, then regenerated in unit RE. The regenerated solvent is recycled through lines 7 and 2 to zone ZA.
