Abstract: In a process for removal of acid gases from a fluid stream the fluid stream is contacted with an absorbent to obtain a treated fluid stream and a laden absorbent. The absorbent comprises a diluent and a compound of the general formula (I) wherein R1 is C1-C3-alkyl; R2 is C1-C3-alkyl; R3 is selected from hydrogen and C1-C3-alkyl; and R4 is selected from hydrogen and C1-C3-alkyl.

Abstract: A process for removing acid gases from a fluid stream, wherein the fluid stream is contacted with an absorbent comprising a compound of the general formula (I), wherein R1 and R2 are independently C1-C4-alkyl; R3 is selected from hydrogen and C1-C4-alkyl, R4, R5 and R6 are independently selected from hydrogen and C1-C4-alkyl; x and y are integers from 2 to 4 and z is an integer from 1 to 3, to obtain a treated fluid stream and a laden absorbent. The process allows for a high cyclic capacity while the compounds of the absorbent have a reduced tendency to foaming and low volatility.

Abstract: An absorbent for the selective removal of hydrogen sulfide over carbon dioxide from a fluid stream, wherein the absorbent contains an aqueous solution, comprising an amine of formula (I) and/or an amine of formula (II) wherein U—V—W is CH—O—CHR5, N—CO—CHR5 or N—CO—NR5; U′—V′—W is C—O—CR5; R1 is independently C1-C5-alkyl; R2 is selected from hydrogen and C1-C5-alkyl; R3 is independently selected from hydrogen and C1-C5-alkyl; R4 is independently selected from hydrogen and C1-C5-alkyl; R5 is selected from hydrogen, C1-C5-alkyl, (C1-C5-alkoxy)-C1-C5-alkyl, and hydroxy-C1-C5-alkyl; and x is an integer from 1 to 10. The absorbent has a reduced tendency for phase separation at temperatures falling within the usual range of regeneration temperatures for the aqueous amine mixtures and a low volatility in aqueous solvents.

Abstract: A process for selectively separating H2S from a gas mixture which also comprises CO2 is disclosed. A stream of the gas mixture is contacted with an absorbent solution comprising one or more amines, alkanolamines, hindered alkanolamines, capped alkanolamines, or mixtures thereof. The H2S/CO2 selectivity of the absorbent solution is preferably greater than about 4.0 for an acid gas loading [mol(CO2+H2S)/mol(amine)] between about 0.2 and about 0.6, and is achieved by reducing pH of the absorbent solution.

Abstract: A process for the preparation of amino alcohols includes condensing a compound of Formula (II), a stereoisomer, a tautomer, or a salt thereof with a compound of Formula (IIIa) or Formula (IIIb), a stereoisomer, a tautomer, or a salt thereof to form a condensation product; hydroxylating or acyloxylating the condensation product in the presence of an oxidant to obtain a hydroxylation or acyloxylation product; and subjecting the hydroxylation or acyloxylation product to one or more subsequent reactions comprising a hydrolysis reaction, alcohol deprotection, an amino lysis reaction, or a combination of two or more thereof to obtain an amino alcohol of Formula (I).
