    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.

    Abstract: The invention relates to a method for removing hydrogen sulphide and carbon dioxide from a stream of fluid, the method comprising: a) an absorption step, in which the stream of fluid is brought into contact with an absorption agent comprising an aqueous solution (i) of an amine of general formula (I), where R1, R2 and R3 are selected independently of one another from among C1-4 alkyl and C1-4 hydroxyalkyl; R4 in each case is independently selected from among hydrogen, C1-4 alkyl and C1-4 hydroxyalkyl; R5 in each case is selected from among hydrogen, C1-4 alkyl and C1-4 hydroxyalkyl; X represents OH or NH(CR1 R2R3); m represents 2, 3, 4 or 5; n represents 2, 3, 4 or 5; and o represents 0 or 1; and optionally (ii) at least one tertiary amine, the molar ratio of (i) to (ii) is greater than 0.05; wherein at least 90% of the hydrogen sulphide is removed from the stream of fluid, the selectivity for hydrogen sulphide in relation to carbon dioxide is no greater than 8 and a CO2- and H2S-loaded absorbent agent is thus obtained; b) a regeneration step, in which at least one sub-stream of the CO2- and H2S-loaded absorption agent is regenerated and a regenerated absorption agent is thus obtained; and c) a recirculation step, in which at least one sub-stream of the regenerated absorption agent is recirculated to the absorption step a). The method permits a high degree of separation of the hydrogen sulphide with a simultaneously high coabsorption of carbon dioxide.

    IPC: B01D53/14

    Abstract: The invention relates to a method for removing acid gases from a fluid flow containing nitrogen oxides, wherein a) the fluid flow is brought in contact with an aqueous absorbent, which contains at least one amino-group-containing compound, in an absorption zone, wherein a deacidified fluid flow is obtained, b) bringing the deacidified fluid flow in contact with an aqueous scrubbing liquid in at least one scrubbing zone and obtaining a deaminated, deacidified fluid flow, wherein the scrubbing liquid is recycled by means of at least one scrubbing zone, c) treating overflow from the at least one scrubbing zone with UV light, and d) combining the UV-treated overflow with the absorbent. The method enables the efficient decomposition of the nitrosamines contained in the absorbent.
