Abstract
A process for the recovery of solvents is disclosed. A hot carrier gas stream laden with solvent vapors from an evaporation space is compressed, cooled, and expanded with production of work for condensing and separating the solvent. The carrier gas stream lean in solvent vapors is conducted back into the evaporation space after being reheated. The whole of the work arising on expansion is transferred in direct mechanical coupling to one of two or more compression stages for compression of the carrier gas stream laden with solvent vapors. An apparatus for practicing the process is also disclosed.
