Definitions

  • the invention is directed to a solvent for the separation of acidic gas constituents from industrial gases, as it can be used in a process in which by means of a liquid sour gas components are washed out of a contaminated technical gas and then regenerates the liquid and in a closed Cycle is returned.
  • the object of the invention is to provide an improved solvent which combines the advantages of the chemical and of the physical absorption agents and enables particularly high loadings.
  • the invention solves the problem by using a liquid for the separation of acidic gas constituents from industrial gases, containing • 0.1 to 100% of an amine or more amines of the formula H 2 N-CH 2 (CHR 2 ) x - (OCH 2 (CHR 3 ) y ) z -OR 1 .
  • R 1 C 1 to C 6 alkyl
  • R 2 H or CH 3
  • R 3 H or CH 3 x: 0 to 3 y: 1 to 3 z: 0 to 10
  • the liquid may also contain residual dissolved constituents of the separated acidic gas constituents as well as impurities.
  • the charged with the acidic gas components technical gas is brought into contact, with conventional methods and devices are used, such as washing columns, membrane contactors, spray scrubbers or the like.
  • the loaded liquid is thereafter usually regenerated in one or more steps, wherein above all stages of depressurization and temperature increase and stripping of the solution by means of a stripping medium in a column are used.
  • the liquid of the invention is suitable for this purpose and can be performed in this way in a closed, continuously operated circuit.
  • the technical gas is considered after the removal of the acidic gas components as purified and can be used for further use.
  • CH 3 (d-alkyl, methyl) is selected as R 1 .
  • H is selected to be equal to 1 and to R 2 .
  • H is selected to be equal to 2 and to R 2 .
  • equal to 1 is selected for y and equal to H for R 3 .
  • a number from 1 to 4, particularly preferably the number 1, is selected for z.
  • the liquid is the component piperazine, also known under the name diethylenediamine, added in an amount up to 10 percent by weight. The preferred embodiment thus results in a liquid of the formula H 2 N- (CH 2 ) 2 -O (CH 2 ) 2 -OCH 3 , which may be diluted with water or another solvent and contains up to 10 percent by weight of piperazine.
  • a CO 2 partial pressure of 0.2 to 2 bar shows a 30 to 50% higher CO 2 uptake, at 5 to 10 bar a 50% higher CO 2 uptake and at 20 bar CO 2 partial pressure even a 75% higher CO 2 uptake for the 85% by weight solution of H 2 N- (CH 2 ) 2 -O (CH 2 ) 2 -OCH 3 over the 50% by weight MDEA solution.
