Abstract

In a process for the recovery of solvents from air, the solvent is adsorbed on activated charcoal and desorbed again by means of steam, after which the steam/solvent mixture is condensed and is separated into a solvent phase and an aqueous phase. The essence of the invention comprises first freeing the aqueous phase from residual solvent by stripping in a column using the steam which is intended for the desorption of the solvent from the activated charcoal filter. All parts of the apparatus at risk of corrosion are composed of borosilicate glass.
