ABSTRACT:
A bed of spent solid adsorbent material previously used for removal of mixed solvent vapors from an air stream is steam stripped; the mixture of steam and vaporized solvent is passed through a condenser; and the resultant liquid condensate is passed to a decanter where the condensate separates into an upper layer of water insoluble solvent components and a bottom layer of water containing the water soluble solvent components. The upper layer is withdrawn for reuse, and the decanter bottoms stream is passed through another bed of solid adsorbent material which removes the organic solvent so as to produce substantially pure water suitable for discharge or reuse. After a period of use this adsorbent bed is also regenerated by steam stripping, and the effluent steam and solvent vapors are recycled to the same condenser serving the air treating adsorbent bed so that a combined condensate is passed to the decanter.
