"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 hydro- carbons, as well as a practically sulfur-free LPG frac- tion and optionally a C5+ fraction, an oxidizing agent is added to the solvent for reacting the sulfur com- pounds 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.
