ABSTRACT:
High purity CO is made quite efficiently with regard to energy consumption from CO.sub.2 -free gas streams containing at least 25% by volume CO and also containing H.sub.2 and small amounts of other gases such as N.sub.2 and CH.sub.4 by (1) complexing the CO in aqueous copper ammonium acylate absorbent solution, (2) stripping the absorbent solution with a small stream of purified CO to desorb traces of noncomplexed gases and (3) decomplexing the absorbent solution to separate purified CO, a small portion of which is recycled to the stripping step.
