Abstract: A method is provided for removing acid gases and ammonia from a fluid stream in which a fluid stream comprising acid gases and ammonia is brought into contact with an aqueous absorption medium. The fluid stream is depleted of acid gases and ammonia and the absorption medium stream, which is charged with acid gases and ammonia, is regenerated in a desorption step. The acid gases and the ammonia are stripped out of the absorption medium and the condensable fractions thereof are condensed. A condensate and also a purified absorption medium stream are obtained. The condensate is ejected in part or completely from the desorption step, or feed in part or completely to a distillation column in which ammonia is separated off overhead as an aqueous solution or in the pure state. A aqueous bottom stream is obtained which is recycled to the absorption step or the desorption step.

Abstract: The invention relates to a method for the removal of carbon dioxide from a gas flow, in which the partial pressure of the carbon dioxide in the gas flow is less than 200 mbar, whereby the gas flow is brought into contact with a liquid absorption agent, comprising an aqueous solution (A) of a tertiary aliphatic amine and (B) an activator of general formula R 1 -NH-R 2 -NH 2 , where R 1 =C 1 -C 6 alkyl and R 2 =C 2 -C 6 alkylene. The method is particularly suitable for treatment of flue gases and also relates to an absorption agent.

Abstract: Removing acid gases from a fluid stream involves passing the fluid stream over one side of a porous membrane while passing a liquid absorbent over the other side, the membrane being contained in a membrane unit with a housing having a plastic or rubber interior surface. Independent claims are also included for: (1) A method of desorbing acid gases from a loaded absorbent by passing the absorbent over one side of a membrane while passing an inert gas over the other side of the membrane; (2) A floating platform for producing and deacidifying natural gas, suitable for operation on open waters, comprising a natural gas production unit, a membrane unit as above for removing acid gases as above, and optionally a membrane unit for desorbing acid gases from the loaded absorbent.

Abstract: Deacidifying a fluid stream containing acid gas impurities by contacting the fluid stream with an absorbent at 0.5-20 bar in at least one absorption stage involves performing at least one absorption stage in an inert scrubber column with a plastic or rubber interior surface. An independent claim is also included for an apparatus for carrying out the process, comprising one or more series-connected scrubber columns filled with wash solution, at least one of the columns being an inert scrubber column with a plastic or rubber interior surface.

Abstract: A description is given of the use of an alkylenediamine of the type R 1 HN-X-NHR 2 , where X is an alkylene radical having from 2 to 9 carbons, R 1 is a hydrocarbon radical having from 1 to 6 carbons and R 2 is a hydrocarbon radical having from 1 to 6 carbons or is hydrogen (H) for removing sour gases from a sour-gas-containing fluid stream, and of a process for deacidifying a fluid stream of this type and a wash liquid or absorption liquid for use in such a process. According to the invention, in at least one absorption step, the fluid stream is brought into intimate contact with a wash liquid, the wash liquid comprising an aqueous amine solution which comprises at least one tertiary aliphatic alkanolamine having from 2 to 12 carbons and an activator of the above type R 1 HN-X-NHR 2 . The fluid stream which is substantially freed from sour gases and the sour-gas-loaded wash liquid are then separated from one another.

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.

Abstract: The invention relates to the use of an alkylene diamine of formula R1HN-X-NHR2, wherein X represents an alkylene radical comprising 2 to 9 C atoms, R1 represents a hydrocarbon radical comprising 1 to 6 C atoms, and R2 represents a hydrocarbon radical comprising 1 to 6 C atoms or a hydrogen atom (H), for removing acid gas from a stream of fluid containing acid gas. The invention also relates to a method for neutralising one such stream of fluid, and a washing or absorption liquid for use in one such method. According to the invention, the stream of fluid is brought into intimate contact with a washing liquid in at least one absorption step, said washing liquid containing an aqueous amine solution which has at least one tertiary aliphatic alkanolamine comprising 2 to 12 C atoms, and an activator of said formula R1HN-X-NHR2. Finally, the stream of fluid which has been extensively cleared of acid gas is separated from the washing liquid which is loaded with acid gas.
