Abstract
Gaseous components are scrubbed from gaseous mixtures with a physical solvent; the latter, after absorption of the scrubbed-out gaseous components, is regenerated by expansion and stripping, wherein the gaseous fraction being released is discharged and the regenerated solvent is recycled into the scrubbing step. To reduce the content of solvent vapors in the gases to be exhausted into the atmosphere, the released gaseous fraction is cooled in heat exchange with non-thermally degasified solvent in order to condense out entrained solvent vapors from the gaseous fraction.
