Abstract: A low temperature vacuum distillation apparatus. The distillation apparatus includes an evaporation section and a condensation section. Fluid flow throughout the system is assisted by an appropriate pump, and heat exchangers, one in each of the evaporation and condensation sections, are interconnected by employment of a heat pump.The condensation section includes a condensation chamber downward from which bubble tubes extend into a collection chamber. Collection chamber is provided with a pump to effect transfer of distillate having volatile impurities entrained therein to a final collection vessel. A pump communicates with vessel to create a partial vacuum therein to ensure venting of the impurities.
