ABSTRACT:
The process of removing H.sub.2 S, CO.sub.2, COS and mercaptans from gases by absorption in an absorbent solution, which is circulated between the absorbing zone and a regenerating zone and which contains at least one organic base dissolved in methanol, has been improved. In accordance with the invention, the absorbent solution contains one or more secondary or tertiary amines general formula R.sub.1 --NH--R.sub.2 or (R.sub.1).sub.2 --N--CH.sub.2 --N--(R.sub.2).sub.2, wherein R.sub.1 and R.sub.2 means CH.sub.2 -- or --CH.sub.2 --CH.sub.3 or CH.sub.3 --CH--CH.sub.3 in a total amount of at least 0.5 to 5.0 moles per liter, and the amine has or the amines have a boiling point between 40.degree. and 110.degree. C. at 1 bar. This improvement permits a selective removal of H.sub.2 S from CO.sub.2 -containing gases.
