Abstract: A method for operating a gas scrubber is disclosed in which components are removed from a crude gas by scrubbing with a chemical or physical scrubbing medium to obtain a pure gas present at elevated pressure which, after heating, is introduced into an expansion machine which after work-performing decompression the pure gas leaves at an exit temperature. The amount of heat supplied to the pure gas during heating thereof is deliberately altered to approximate the exit temperature thereof to a predetermined target value at all times.

Abstract: A method and a device for separating off an electrolyte from a first synthesis gas and a second synthesis gas, each containing an electrolyte. The two synthesis gases are each subjected in a scrubbing column to a water scrubbing, in which a substantially electrolyte-free synthesis gas and also a scrubbing water loaded with an electrolyte that has been separated off are obtained. At least a part of the scrubbing water that was loaded with an electrolyte that has been separated off in the scrubbing of the first synthesis gas is used as scrubbing medium in the scrubbing of the second synthesis gas.

Abstract: The invention relates to a process and a device for generating a fuel gas for a gas turbine by separating off sulphur components from a gas mixture containing hydrogen, carbon monoxide, carbon dioxide and also carbonyl sulphide and/or hydrogen sulphide, which gas mixture is in this case scrubbed in a physical gas scrubber with a methanol scrubbing medium at a pressure between 30 and 80 bar(a) in order to obtain a first sulphur-free gas mixture and also a methanol scrubbing medium loaded with sulphur components and carbon dioxide, which methanol scrubbing is then regenerated, wherein a carbon dioxide-rich gas phase that contains sulphur components and is formed by pressure reduction is treated in a further gas scrubber with a methanol scrubbing medium in order to back-wash sulphur components and to generate a second sulphur-free gas mixture.

Abstract: A method for operating a gas scrubber, wherein a first feed gas is scrubbed in a first scrubbing installation and a second feed gas is scrubbed in a second scrubbing installation operated in parallel to the first, with the same physically acting scrubbing medium, in order to dissolve sulfur components out of the feed gases containing contaminants and to obtain desulfurized gas streams, wherein scrubbing medium streams loaded with sulfur components and co-absorbed carbon monoxide arise, and wherein the first feed gas, the carbon monoxide partial pressure of which is lower than that of the second, is scrubbed in the first scrubbing installation at a lower pressure than the second feed gas in the second scrubbing installation. The scrubbing medium is loaded in the second scrubbing installation with sulfur components and co-absorbed carbon monoxide is expanded into the first scrubbing installation to convert dissolved carbon monoxide to the gas phase.
