Abstract: Absorption medium for sour gases, comprising an oligoamine (A) of the general formula (I) and a primary or secondary alkanol amine (B) of the general formula (II), in which the weight ratio of oligoamine (A) to primary 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 solution being temperature-controlled at a temperature of 20 to 80°C.

IPC: B01D53/14
Abstract: The invention relates to an absorbent for removing acid gases from a fluid flow, comprising an aqueous solution A) of at least one cyclic amine compound having exclusively tertiary amine groups and/or sterically hindered secondary amine groups, and B) of at least one cyclic amine compound having at least one sterically unhindered secondary amine group. The absorbent comprises, for example, an aqueous solution of A) 1-hydroxyethyl-piperidine and/or triethylenediamine and B) piperazine. The absorbent is suited especially for separating carbon dioxide from flue gases and meets the following criteria: (i) sufficient capacity at low CO2 partial pressures; (ii) sufficiently fast absorption speed at low CO2 partial pressures; (iii) stability toward oxygen; (iv) low vapor pressure in order to reduce solvent losses; and (v) low energy requirement for regenerating the absorbent.
