ABSTRACT:
A hydrocarbon gas containing H2S, mercaptans and CO2is 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bar and supplied with a selective solvent, a solvent stream loaded with H2S and a roughly desulfurized gas stream are withdrawn, the H2S loaded solvent stream is charged to a regeneration plant and the roughly desulfurized gas stream is charged to an absorption and regeneration plant operated at a pressure of 20 to 80 bar, a large first gas stream of H2S and CO2and an unloaded solvent stream are withdrawn from the absorption regeneration plant, and the large first gas steam of H2S and CO2is supplied to a Claus plant, and a valuable hydrocarbon gas stream is withdrawn from the absorption and regeneration plant.
