A hydrocarbon gas containing H<SUB>2</SUB>S, mercaptans and CO<SUB>2 </SUB>is fed to an absorption plant operated at a pressure of 20 to 80 bar and supplied with a selective solvent, a solvent stream loaded with H<SUB>2</SUB>S and a roughly desulfurized gas stream are withdrawn, the H<SUB>2</SUB>S loaded solvent stream is charged to a regeneration plant and the roughly desulfurized gas stream is charged to an absorption and regeneration plant operated at a pressure of 20 to 80 bar, a large first gas stream of H<SUB>2</SUB>S and CO<SUB>2 </SUB>and an unloaded solvent stream are withdrawn from the absorption regeneration plant, and the large first gas steam of H<SUB>2</SUB>S and CO<SUB>2 </SUB>is supplied to a Claus plant, and a valuable hydrocarbon gas stream is withdrawn from the absorption and regeneration plant.
