    Abstract: Absorbent (I) for removing acid gases (II) from fluids comprises (a) tertiary alkanolamine(s) and (b) an amine selected from hydroxyethylpiperazine, bis(hydroxyethylpiperazine or a mixture of these. An independent claim is also included for a process for absorption of (II) from fluid streams by contacting the fluid stream with absorbent (I) to give a fluid stream depleted in (II) and (I) charged with (II).

    Abstract: The disclosure concerns a process for removing mercaptans from fluid streams comprising same, especially from hydrocarbon gas streams, for example natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or else from liquid hydrocarbons, for example LPG (liquefied petroleum gas). The invention comprises intimately contacting the fluid stream in an absorption or extraction zone with a scrubbing liquor comprising at least one aliphatic alkanolamine of 2-12 carbon atoms, the amount of wash liquor being supplied to the absorption or extraction zone being sufficient to remove at least CO2 and H2S essentially completely from the fluid stream, and separating the substantially decontaminated fluid stream and the contaminated wash liquor and discharging them from the absorption zone. The substantially complete removal of CO2 and H2S is accompanied by the removal from the gas, stream of a very large portion of the mercaptans as well, without a significant fraction of the hydrocarbon gases dissolving in the wash liquor.

    Abstract: A process for removing acidic gas constituents, of the group consisting of CO2, H2S, COS, CS2 and mercaptans, from gases, in which, in an absorption step, a dirty gas rich in acidic gas constituents is brought into contact with an absorption medium, as a result of which a clean gas low in acidic gas constituents and an absorption medium laden with acidic gas constituents are obtained, the absorption medium used being a mixture comprisinga) from 0.1 to 50% by weight of one or more mono-cyclic or bicyclic nitrogen heterocycles which are unsubstituted and/or monosubstituted or poly-substituted on the carbon by OH, C1-C3 alkyl and/or C1-C3 hydroxyalkyl and which have from 5 to 14 ring atoms and 1 or 2 heterocyclically bound nitrogen atoms per ring as component A,b) from 1 to 60% by weight of a monohydric and/or polyhydric alcohol as component B,c) from 0 to 60% by weight of an aliphatic aminoalcohol as component C,d) from 0 to 98.9% by weight of water as component D,e) from 0 to 35% by weight of K2CO3 as component E,where the sum of components A, B, C, D and E is 100% by weight.
