ABSTRACT:
A process for the separation of mercaptans from gases, and especially from natural gas by absorption in a hydrocarbon oil and regeneration of the oil by oxidation of the mercaptans to sulfonic acids. The oxidation can be carried out at the absorption temperature and pressure by means of an oxidant in an aqueous medium. The regenerated oil is recycled after separation from the aqueous phase containing the sulfonic acids.
