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.

Method and device for the desulphurisation of a gas stream containing hydrogen sulphide

A compressor rotor blade for an axial-type compressor has a blade profile having a transonic section and a profile section which extends in the transonic section and has concave and convex suction-side regions on the suction side, the convex suction-side region arranged downstream of the concave suction-side region, and has convex and concave pressure-side regions on the pressure side, the concave pressure-side region arranged downstream of the convex pressure-side region. Curvature progressions on the pressure side and on the suction side are both applied in a continuous manner over a profile chord of the profile section, the positions of the minimum values of the curvature progressions deviate from each other by not more than 10% of the length of the profile chord, and the positions of the maximum values of the curvature progressions deviate from each other by not more than 10% of the length of the profile chord.
