Abstract
A method for the desulphurisation of a gas stream containing hydrogen sulphide, in particular a combustion gas stream used for combustion in a gas turbine, wherein the gas stream is brought into contact with a scrubbing medium containing a catalyst to absorb the hydrogen sulphide, forming elementary sulphur; the catalyst is reduced on formation of the elementary sulphur; the scrubbing medium containing the reduced catalyst is fed to a regeneration stage in which the reduced catalyst is regenerated by oxidation with an oxygen-containing gas which is fed to the regeneration stage; the oxygen-containing gas is fed to the regeneration stage from a compression stage of the gas turbine; and the gas which is depleted of oxygen during regeneration of the catalyst is fed to at least one turbine stage fluidically connected downstream of the compression stage.
