    Abstract: The present invention relates to a process for removing mercaptans from a gas stream. First, a gas stream comprising at least a mercaptan of the general formula R1—SH, wherein R1 is an alkyl group comprising 1 to 4 carbon atoms, may be contacted with an absorption medium comprising a solvent, a substituted disulfide of the general formula R2—SS—R3 wherein R2 and R3 are carbon comprising substituents of which the corresponding R2—SH and R3—SH thiols have a vapour pressure below the vapour pressure of any R1—SH thiol and at least one of R2 and R3 is an electron withdrawing group; and at least a catalytic amount of a base. The absorption medium may be retrieved and regenerated in a regeneration unit. The regenerated absorption solution may be recycled and subjected to oxidation.
