Absorption medium for acid 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 the piperazine derivative (B) is 0.2 to 25, and also process for removing acid 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 which is brought to and maintained at a temperature of 20 to 80&#xb0; C.

Absorption medium and method for removing sour gases from fluid streams, in particular from flue gases

Absorption medium for acid gases comprising an oligoamine (A) of the general formula (I) and a primary or secondary alkanolamine (B) of the general formula (II) in which the weight ratio of oligoamine (A) to the primary or secondary alkanolamine (B) is 0.2 to 4, and also the process for removing acid gases from a gas stream by contacting the gas stream at a pressure of 0.05 to 10 MPa abs with an aqueous solution brought to and maintained at a temperature of 20 to 80&#xb0; C. of said absorption medium.
