Abstract:
An absorption medium for removing acid gases from a fluid stream comprises an aqueous solution (A) of an alkali metal salt of an N,N-di-C1-C4-alkylaminocarboxylic acid and (B) N-hydroxyethylpiperazine. The absorption medium has a low vapor pressure and an increased resistance to oxygen. Preferred fluid streams are combustion exhaust gases or biogas.
