Apparatus and method for reducing solvent vapor losses

摘要: Parts to be cleaned, degreased, or having paint stripped therefrom, by a solvent such as halogenated hydrocarbon are lowered into and lifted out of tank via an enclosure disposed above the tank. A pair doors at top opening second bottom allow isolation from below outside environment above. with open closed. They then further for cleaning, degreasing stripping closed open. After stripping, parts back With both pairs closed, air contaminated vapor is conveyed system recovering liquid solvent, refrigerated condenser separator, carbon adsorption system, absorption/stripping using inert medium fraction boiling point substantially higher than that solvent. When in solvent-free, enclosure. No vapors discharged atmosphere.
