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 1.0. 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: Disclosed is an absorbent for eliminating carbon dioxide from a gas flow. Said absorbent comprises an aqueous solution of at least one amine and at least one amino carboxylic acid and/or amino sulfonic acid. Additionally using an amino carboxylic acid or amino sulfonic acid reduces the amount of energy required for regenerating the absorbent.

Abstract: Method for the removal of acid gases from a fluid flow containing hydrocarbons or from a fluid flow containing oxygen, by means of bringing the fluid flow in contact with an aqueous solution, which is substantially free of inorganic alkaline salts and which contains (i) at least one amine and (ii) at least one metal salt of an amino acid and/or of a sulfur amino acid. The combined use of amino acid salt and/or sulfur amino acid salt reduces the coabsorption of carbohydrates and respectively oxygen, without substantially affecting the absorption velocity with which the acid gases are absorbed, without substantially reducing the absorption capacity of the solution for acid gases and without substantially raising the consumption of energy necessary for regeneration.
