Abstract: An absorbent for removing acidic gases from a fluid stream, comprising an aqueous solution a) of at least one metal salt of an amino carboxylic acid and b) of at least one acidic promoter, where the molar ratio of b) to a) is in the range from 0.0005 to 1Ø The acidic promoter is selected from mineral acids, carboxylic acids, sulfonic acids, organic phosphonic acids and partial esters thereof. The absorbent exhibits, compared to absorbents based on amino acid salts, a reduced requirement for regeneration energy, without significantly reducing the absorption capacity of the solution for acidic gases. In a process for removing acidic gases from a fluid stream, the fluid stream is contacted with the absorbent.

Abstract: An absorbent for removing acid gases from a fluid flow comprises an aqueous solution of a) at least one amine and b) at least one phosphonic acid, wherein the molar ratio of b) to a) ranges between 0.0005 and 1Ø For example, the phosphonic acid is 1-hydroxyethane-1, 1-diphosphonic acid. Compared to absorbents based on amines or amine/promoter combinations, the absorbent requires less regeneration energy without substantially reducing the solution's capacity to absorb acid gases.

Abstract: The invention relates to the use of an amine of formula (I) where the groups R1 to R5 are defined as they are in the description, as well as to an absorption agent and a method for removing acid gases from a fluid flow, particularly for selectively removing hydrogen sulphide over carbon dioxide. The invention also relates to certain amines suitable for selectively removing hydrogen sulphide. Absorption agents based on the amines of formula (I) have a high degree of selectivity, high loading capacity and good regeneration capacity.

Abstract: Disclosed is an absorbent for removing carbon dioxide from a fluid flow, said absorbent comprising an aqueous solution of: a) an amine of general formula (I), wherein R1, R2 and R3 are selected independently from one another from C1-4-alkyl and C1-4-hydroxyalkyl, R4 in each case is selected independently from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl, R5 in each case is selected independently from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl, X stands for OH or NH(CR1R2R3), m stands for 2, 3, 4 or 5, n stands for 2, 3, 4 or 5, and o stands for 0 or 1; and b) at least one activator selected from 5-, 6-, or 7-membered heterocycles with an NH group in the ring and one or to other heteroatoms in the ring, which are selected from nitrogen and oxygen. The absorbent enables a rapid absorption of carbon dioxide from fluid flows.
