Abstract: An absorbent for selective removal of hydrogen sulfide from a fluid stream comprises an aqueous solution comprising a) a tertiary amine; b) an aminic pH promoter selected from the compounds mentioned in the description; where the molar ratio of b) to a) is in the range from 0.05 to 1.0; and c) an acid having a pKA of less than 6 in such an amount that the pH of the aqueous solution measured at 120° C. is 7.9 to less than 8.8. Also described is a process for removing acidic gases from a fluid stream, in which the fluid stream is contacted with the absorbent. The absorbent is notable for a low regeneration energy.

Abstract: The invention relates to a premix for producing an absorption agent for removing acid gases from a fluid flow, comprising a) at least one tertiary amine and/or a sterically inhibited secondary amine; b) a dicarboxylic acid in a quantity, calculated as a neutralization equivalent based on the protonatable nitrogen atoms in a), of at least 30%, wherein the dicarboxylic acid is soluble in water at a temperature of 20 °C to a maximum of 15 g dicarboxylic acid per 100 g of water; and c) 20 to 80 wt% water. The invention further relates to a method for producing an absorption agent from the premix. According to the invention, the premix represents a transportable and easily workable solution of a dicarboxylic acid of low solubility in water for the production of an absorption agent for removing acid gases from a fluid flow.

Abstract: A compound of the general formula (I) in which R1, R2 and R3 are independently selected from C1- 4-alkyl and C1-4-hydroxyalkyl; each R4 is independently selected from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl; each R5 is independently selected from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl; m is 2, 3, 4 or 5; n is 2, 3, 4 or 5; and o is an integer from 1 to 10. A preferred compound of the formula (I) is 2-(2-tert-butylaminoethoxy)ethylamine. Absorbents comprising a compound of the formula (I) have rapid absorption of carbon dioxide from fluid streams and are also suitable for processes for the simultaneous removal of H2S and CO2, where given H2S limits have to be observed but complete removal of CO2 is not required.
