Process for the removal of acid gases from a residual gas of an alcohol synthesis

摘要

The invention relates to a process for the separation of carbon dioxide (11) from a hydrogen, carbon monoxide and carbon dioxide-containing gas mixture (1) obtained in an alcohol synthesis (M) as a residual gas, wherein the residual gas (1) is subjected to a gas scrubber (A). Characteristic of the method is that the gas scrubbing (A) is a physical gas scrubbing in which carbon dioxide in an absorption step by means of a cryogenic, used as detergent (3) alcohol from the residual gas (2) is washed out.
