Abstract: Absorption medium for sour ga-ses, comprising an oligoamine (A) of the gene-ral formula (I) and a primary or secondary alka-nol amine (B) of the general formula (II), in which the weight ratio of oligoamine (A) to pri-mary or secondary alkanol amine (B) is 0.2 to 4, and a method for removing sour gases from a gas stream by contacting the gas stream at a pressure of 0.05 to 10 MPa abs with an aqueous solution of said absorption medium, said soluti-on being temperature-controlled at a tempera-ture of 20 to 80°C.
