METHOD AND DEVICE FOR SEPARATING AND RECOVERING VOLATILE SOLVETN

摘要

Volatile solvents are recovered from water vapour-containing waste air by passing the waste air first through a molecular sieve packing which exclusively adsorbs the water vapour, and subsequently through a molecular sieve packing which exclusively adsorbs the solvent vapours. The molecular sieve packings are regenerated by heating, in such a way that anhydrous solvent is recovered.
