Abstract: A contaminated solvent recycling system is disclosed and claimed. The system comprises a distillation vessel having an upper distillation zone and a separate, lower, waste collection zone. A heater heats contaminated solvent feed within the distillation zone to distill off the solvent. By separating the distillation zone from the waste collection zone, the distillation zone can process consecutive batches of contaminated solvent feed. The waste collection zone can accommodate waste accumulating from the distillation process for extended periods of time between waste removal operations.

Abstract: In a solvent recycling system, a distillation vessel having an upper distillation zone and a lower waste collection zone and means whereby solvent waste falls into said waste collection zone before solvent enters said distillation zone. The system preferably has a solvent vapour outlet and a heating means, whereby solvent enters the vessel from above through the solvent feed inlet and solvent waste falls into said waste collection zone before distillation is commenced, and a shut-off means or filling tube extending below the distillation zone associated with the inlet to prevent solvent vapours exiting the vessel through the inlet during distillation.

Abstract: A parts cleaner for use in a process whereby solvent is preferred to always be available and is preferred to be as clean or pure as possible for use, comprising two containers respectively for clean solvent and for capture of used solvent or a single container having separate zones for clean and used solvent, said clean container having an outlet for supplying clean solvent for cleaning. The clean container may have an outlet for supplying clean solvent for cleaning and an inlet for clean recycled solvent, the used solvent container having an inlet for used solvent, an outlet for supplying used solvent for cleaning and an outlet for supplying used solvent for recycling. The used solvent container may have an outlet for supplying used solvent for cleaning and means for automatically switching between the outlets supplying said clean solvent and said used solvent for cleaning.
