Closed system solvent stripping and reclaiming apparatus

A solvent stripping and reclaiming apparatus comprising:

• (a) vessel means for receiving solvent laden material, said vessel means having a first valve controlled inlet for admitting live steam to said vessel means, a second valve controlled inlet for admitting gas to said vessel means, a third inlet for admitting water to said vessel means, means for heating said vessel means, a water supply means for supplying water to said third inlet, and a steam and solvent vapor outlet from said vessel means;
• (b) condenser means for cooling steam and solvent vapors, to condense them into the liquid phase, said condenser means having a steam and solvent vapor inlet connected by valve controlled conduit means to said outlet from said vessel means, and a liquid outlet;
• (c) separator means for receiving liquid from said condenser means and separating said solvent and water based on their immiscibility, said separator means having an output for solvent thereby reclaiming said solvent and an outlet for solvent saturated water;
• (d) adsorber means for selectively adsorbing solvent from a solvent vapor and an air stream, said adsorber means directly connected by conduit means to said outlet from said vessel means, said adsorber means including a housing containing a bed of activated carbon adsorbent, said housing having a solvent vapor and air inlet and an exhaust outlet that discharges solvent-free air into the atmosphere;
• and
• (e) blower means for forcing air and solvent vapor from said vessel means into said adsorber means for the purpose of adsorbing said solvent vapors therein, said blower means having an intake connected by a valve controlled conduit means to said steam and solvent vapor outlet of said vessel means for receiving air and solvent vapor therefrom, said blower means having an exhaust outlet connected by conduit means to said solvent vapor and air inlet of said carbon bed adsorber.
