    Abstract: The invention relates to a method for the deacidification of a fluid stream, containing acidic gases as impurities, whereby the fluid stream is brought into intimate contact with an absorption agent at a pressure of 0.5 to 20 bar in at least one absorption step, with the proviso that the absorption step and, in the case of multiple absorption steps, at least one of the absorption steps is carried out in an inert scrubbing column, the internal surface of which is essentially made from plastic or rubber.

    Abstract: Method for simulation of mass transport controlled separation processes in which a core-film layer is used to describe a mass exchange taking place at a phase border (P). According to the approach, an iterative solution of an implicit differential equation system is undertaken for discretization of an observed transfer area (10) of the core-film layer, from which the differential equation system, especially based on the Stefan-Maxwell equation, is generated. An independent claim is made for a device for simulation of mass transport controlled separation processes in which a core-film layer is used to describe a mass exchange taking place at a phase border.

    Abstract: Disclosed is a method for deacidifying a fluid stream containing acidic gases as contaminants, according to which the fluid stream is brought into intimate contact with a washing liquid in at least one absorption step. Said washing liquid represents an aqueous solution containing a) tertiary aliphatic alkanolamines (alkanolamine A), at least 30 percent by weight of said tertiary aliphatic alkanolamines being 3-dimethylamino-1-propanol, and b) secondary aliphatic amines (activator B), at least 20 percent by weight of said secondary aliphatic amines being piperazin. The fluid stream which has been essentially purified of the acidic gases is then separated from the washing liquid that is loaded with acidic gases.

    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.
