Abstract: A cryogenic process for the removal of acidic gases from natural or synthetic gases comprising preliminary cooling of the gas to condense a portion of the acidic gases contained in the gas, and contacting the cooled gas with a mixture of one or more organic selective solvents such as low molecular weight esters, alcohols and ethers and one or more organic compounds such asheptane,fractions of natural gasoline containing hydrocarbons;monoaromatic compounds;dimethylethers of polyglycols having the glycolic unit CH.sub.2 --CH--O-- repeated three to five times;methoxy- and/or ethoxyalcohols, wherein the alcoholic group is a radical having from 3 to 4 carbon atoms in either linear or branched chain.

Abstract: In a process for the regeneration of a scrubbing medium which has been utilized in a scrubbing operation and therein loaded with scrubbed-out components, the scrubbing medium is expanded and regenerated and hence can be reused in the scrubbing operation. In order to be able to subject expansion gases obtained during the expansion to an after-treatment under elevated pressure, or to be able to discharge these expansion gases under a higher pressure, the loaded scrubbing medium is expanded in at least two stages. Expansion in one stage is performed by means of a liquid-jet compressor and the expansion gases of a subsequent expansion stage are brought to an elevated pressure by means of the liquid-jet compressor.
