THE REMOVAL OF SULFUR COMPOUNDS FROM GASES" Abstract of the Disclosure, For the removal of sulfur compounds especially, H2S, from gases that contain hydrocarbons and/or CO2, the gases are scrubbed with a physical solvent which is, regenerated and reused. To obtain sulfur free of hydrocarbons, as well as a practically sulfur-free LPG fraction and optionally a C5+ fraction, an oxidizing agent is added to the solvent for reacting the sulfur compounds to elemental sulfur, and the sulfur is separated. The concomitantly absorbed hydrocarbons and/or CO2 can then be desorbed from the separated solvent by physical regeneration and can be recovered.
