Abstract:
A process for the removal of CO.sub.2 and sulfur compounds from an industrial gas selected from the group which consists of natural gas and raw synthesis gas, comprising the steps of:(a) scrubbing said industrial gas in an absorber with an absorbent consisting essentially of a mixture of N-formylmorpholine and N-acetylmorpholine at a temperature between -20.degree. C. and 40.degree. C. at a working pressure of 10 to 150 bar;(b) withdrawing a spent absorbent laden with absorbed acid gas components from said absorber;(c) regenerating the spent absorbent laden with absorbed acid gas components to form a regenerated absorbent; and(d) recycling the regenerated absorbent to said absorbers, said absorbent consisting essentially of 30 to 70 parts by weight N-formylmorpholine and 70 to 30 parts by weight N-acetylmorpholine, per 100 parts by weight of the absorbent and containing 0.1 to 5 parts by weight H.sub.2 O.
