Functional Principle of Vacuum Distillation

The polluted solvent is drawn into the distillation vessel via the optional pre-heater unit and the admission valve by means of vacuum. Subsequently, the contents of the distillation vessel is indirectly heated by thermo-oil inside the double jacket. The solvent evaporates and is exhausted out of the steam vessel by the vacuum pump. Finally, it is cooled in a condenser by an external medium.

The clean solvent (distillate) can be resupplied instantly, or it can be held ready in suitable storage tanks / barrels. The remaining residues are manually or automatically removed after one or more distillation processes.
