ABSTRACT:
A portable solvent recovery distillation apparatus for improved on-site recovery of highly flammable solvent from a batch of spent solvent. Both evaporation of the spent solvent and condensation of the purified solvent vapors are conducted within a common tank under reduced pressure conditions maintained by an air-operated vacuum pump. Heating of the spent solvent is accomplished by a hot fluid circulating in indirect heat exchange relationship with the spent solvent. The apparatus is totally non-electrical for increased safety of operation.
