Abstract

In a process for vacuum distn. without using external heat, the distilland and the distillate are under vacuum at temperatures which are equal or slightly different. The satd. vapour from the distilland is partly compressed to displace the vapour-liquid equilibrium toward the formation of liq. The heat of condensn. is exchanges with the heat of evapn. The compressor is a vaned turbine or pump or a Rootes type compressor and the heat transfer is carried out in exchangers of the fluid circulation type. The temperatures of the distilland and the distillate are kept uniform by mechanical agitation. The process is partic. useful for distilling sea water. It uses considerably less energy than distillations in which heat is supplied to raise the temp. to the boiling point and to vaporise the liquid, and energy is used to condense the vapour.
