Abstract

For the removal of sulfur compounds, especially H.sub.2 S, from gaseous mixtures, said mixtures are scrubbed with a physical solvent which is later regenerated and reused. To the solvent are added (a) an oxidizing agent for converting the sulfur compounds into elemental sulfur, and (b) additive means for increasing the settling rate of the thus-formed sulfur.
