Abstract

See full text

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.
