Abstract: Acid constituents, eg. H2S and CO2 or their mixtures, are removed from industrial gases or natural gases by means of a washing agent which contains the unsymmetrical methyl isopropyl ethers of polyethylene glycols. The washing can be carried out with simultaneous drying of the gas , especially in the case of natural gases, since the anhydrous ethers are able to absorb water.

Abstract: In a process for removing CO2 or H2S or both from gases which contain said constituents by washing the gases with an aqueous solution of a scrubbing liquid and subsequently regenerating the scrubbing liquid, the improvement which comprises: using a scrubbing liquid which contains up to 0.8 mole/l of piperazine as an absorption accelerator and at least one solvent of the group of chemical solvents in an amount of 1.5 to 4.5 moles/l, wherein that chemical solvent is selected from the group consisting of aminocarboxylic acids, potassium hydroxide and alkanolamines. The washing process is used for natural gases, coke-oven gases, gases from the gasification of coal and synthesis gases, of any origin.
