Abstract
The recovery of solvents from waste gases takes place according to the state of the art by condensation, freezing out or desublimation of the solvent in recuperative cold reservoirs which can be switched over. In order to reduce the amount of equipment and the cold losses, the condensation and freezing-out operations are run continuously in a shaped-object reservoir through which cooled shaped objects move in a countercurrent to the waste gas.
