A method and apparatus for separating and recovering volatile solvents from exhaust air containing volatile solvents and water vapor, the method including passing the exhaust gas alternatively through one of two beds of molecular sieve packings composed of a material capable of adsorbing the water vapors therein and then through one of two beds of molecular sieve packings composed of a material capable of adsorbing the solvent vapors therein. Heated air or inert gas is passed through the beds not being used to adsorb either the water vapor or the solvent vapors so as to regenerate the molecular sieve packings. The air or inert gas containing solvent is passed through a condenser and a drip collector so as to recover the solvent therefrom.
