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. |
