Method for the absorptive purification of a gas stream of vaporous or gaseous impurities

摘要

Method for operating a sorption filter in which the sorption filter separates absorbable admixtures of a gas stream and is regenerated by a heated gaseous desorption medium after being loaded to an equilibrium loading corresponding to the admixtures. The gas stream to be purified is conducted through at least two sorption material layers, with the flow going through all sorption material layers in the manner of a parallel circuit. In the desorption of the loaded sorption material layers, the gaseous desorption medium flows in series through the sorption material layers.
