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.

Abstract: The invention relates to a method for the removal of acid gases from a gas flow, in which the gas flow containing an acid gas, having a sum of the partial pressures for the acid gases not exceeding 1500 mbar, is brought into contact with an aqueous absorption agent in an absorption step. The absorption agent used comprises methyldiethanolamine and piperazine in a concentration of at least 8 wt. % of the absorption agent. A gas flow with reduced acid gas content and an absorption agent loaded with acid gas are obtained.

Abstract: A description is given of an absorption medium for removing carbon dioxide from a gas stream, which comprises an aqueous solution of at least one amine and at least one aminocarboxylic acid and/or aminosulfonic acid. The concomitant use of an aminocarboxylic acid or aminosulfonic acid reduces the energy required for regeneration of the absorption medium.

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).
