Abstract: A method for removing carbon dioxide (CO
2 ) from a recycle gas system by means of an absorbent, wherein the CO
2 occurs within a process in which ethylene is oxidized by oxygen (O
2 ) to ethylene oxide (EO) in the gas phase in the presence of a catalyst, in which CO
2 is generated as by-product, by using, as absorbent, an aqueous solution of one or more amines, wherein, for further purification of the recycle gas stream obtained after the CO
2 absorption step, it is brought into intimate contact with water to which have not been added a mineral acid or higher glycol.

Abstract: Absorption medium for sour gases, comprising an oligoamine (A) of the general formula (I) and a piperazine derivative (B) of the general formula (II), in which the weight ratio of oligoamine (A) to piperazine derivative (B) is 0.2 to 25, 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 means, said solution being temperature-controlled at a temperature of 20 to 80°C.
