摘要： A process for removing sulphur oxides from a fluid stream,such as flue gas, that comprises a) providing a non-aqueous absorption liquid containing at least one hydrophobic amine, the non-aqueous absorption liquid being incompletely miscible with water; b) treating the fluid stream in an absorption zone with the non-aqueous absorption liquid to transfer at least part of the sulphur oxides into the non-aqueous absorption liquid and to form a sulphur oxide-hydrophobic amine-complex; c)causing the non-aqueous absorption liquid to be in liquid-liquid contact with an aqueous liquid where by at least part of the sulphur oxide-hydrophobic amine-complex is hydrolyzed to release the hydrophobic amine and sulphurous hydrolysis products, and at least part of the sulphurous hydrolysis products is transferred into the aqueous liquid; d)separating the aqueous liquid from the non-aqueous absorption liquid. The process mitigates absorbent degradation problems caused by sulphur dioxide and oxygen in flue gas.

摘要： The invention relates to an absorption agent for removing acidic gases from a fluid flow, comprising an aqueous solution (A) of an alkali metal salt of an N,N-di-C
1 -C
4 -alkyl-amino carbolic acid and (B) N-hydroxyethylpiperazine. The absorption agent comprises a lower vapor pressure and increased resistance to oxygen. Preferable fluid flows are combustion exhaust or biogas.-

摘要： 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.

摘要： 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 1.0. 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.
