Abstract
A process for the recovery of carbon monoxide from a purge gas from acetic acid synthetic containing at least carbon monoxide, nitrogen and hydrogen, wherein the purge gas (6) containing at least carbon monoxide, nitrogen and hydrogen is separated into a gas fraction (11) rich in carbon monoxide and a residual gas fraction (12, 13) rich in nitrogen and hydrogen by an adsorption process (G), preferably by a pressure change absorption process, and the gas fraction (11) rich in carbon monoxide is returned upstream of the acetic acid.
