Abstract

A method and device for the desulphurisation of a hydrogen sulphide-containing gas flow, in particular for combustion in a gas turbine, wherein the gas flow is brought into contact with a washing agent containing a catalytically active component for the absorption of the hydrogen sulphide and forming elementary sulphur, wherein the catalytically active component is reduced in the formation of the elementary sulphur, wherein the washing medium containing the reduced catalytically active component is supplied to a regeneration stage, in which the reduced catalytically active component is converted back via oxidation with an oxygen-containing gas supplied to the regeneration stage, and wherein the oxygen-containing gas is supplied to the regeneration stage from a compressor of a gas turbine. Air from the compressor of a gas turbine is used for purifying a washing medium used for the desulphurisation of a gas flow.
