    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: The invention relates to a method for the separation of ammonia from a mixture which contains ammonia and whose boiling point in an ammonia-free state is more than 50 DEG C higher than the boiling point of pure ammonia, characterized in that said method comprises n stages, n being a natural number of at least 2, wherein a) said mixture is fed to stage 1; b) at each stage m, m being a natural number of 1 to n-1, part of the ammonia is separated from the educt mixture fed from stage 1 at a pressure Pm by means of evaporation in order to obtain a product mixture which has an ammonia content corresponding to pressure Pm and temperature tm, and gaseous ammonia, c) the product mixture obtained in stage m is used in step m+1 as an educt mixture, with the exception of stage n, according to step b), d) in step n, the ammonia is separated at a pressure Pn and temperature tn either partially or fully from the educt mixture fed from stage n-1 by means of evaporation in order to obtain a product and gaseous ammonia, each pressure Pm being greater than Pm+1.

    Abstract: Treatment of combustion gases (I) containing sulfur dioxide (SO2) and carbon dioxide (CO2) comprises a first absorption stage (a), in which SO2 is removed by scrubbing with aqueous suspension of calcium hydroxide or calcium carbonate, followed by a second absorption stage (b) in which CO2 is removed by scrubbing with amine(s) (II) (optionally in aqueous solution), aqueous potassium hydroxide solution (optionally containing (II)) or aqueous aliphatic aminoacid alkali metal salt solution, the CO2-charged scrubbing liquid from (b) being regenerated and recycled. Treatment of combustion gases (I) containing sulfur dioxide (SO2) and carbon dioxide (CO2) as impurities involves: (1) an absorption stage (a), in which the gas is intimately contacted with a scrubbing liquid (A) comprising an aqueous suspension of calcium hydroxide or calcium carbonate, followed by separating the SO2-charged scrubbing liquid (A) and the remaining, non-absorbed part of (I); (2) an absorption stage (b), in which the non-absorbed part of (I) is intimately contacted with a scrubbing liquid (B) comprising a solution (b1) consisting of at least one amine compound (II) (optionally in aqueous solution), a solution (b2) consisting of water, potassium hydroxide and optionally (II) or a solution (b3) consisting of water and the alkali metal salt of an aliphatic aminoacid, followed by separating the CO2-charged scrubbing liquid (B) and the remaining, non-absorbed part of (I); and (3) regenerating the CO2-charged solution (B) and recycling it to absorption stage (b). (II) are selected from 4-12C aliphatic or cycloaliphatic amines; 4-12C alkanolamines; and cyclic amines consisting of 5-7 membered heterocycles consisting of 1 or 2 N atoms and 1 or 2 alkanediyl groups.
