Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is reduced to less than its vapor pressure (usually less than atmospheric pressure) causing evaporation of the most volatile liquid(s) (those with the lowest boiling points). This distillation method works on the principle that boiling occurs when the vapor pressure of a liquid exceeds the ambient pressure. Vacuum distillation is used with or without heating the mixture.
This is the most effective process for used oil recycling , YJ-TY vacuum system is to refine waste oil in a batch process.Waste lube oil after pre-treatment ,will be pumped into a distillation kettle underr vacuum. As the temperature in the kettle rises, various cuts are liberated and rise as vapors, to be condensed in a condenser. The condenser, along with the heating kettle, is maintained under vacuum by a vacuum pumping system. The condensed products are available as different products corresponding to various kettle temperatures .
