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.
