Method and apparatus for distillation of liquids such as sea water, brackish water, waste water, or the like, which also may be used for cooling purposes, are disclosed. The apparatus includes a vacuum tank, or vessel, into which liquid to be distilled, such as saline water, is fed to partially fill the tank. If desired, heating means may be included for heating the liquid adjacent the surface thereof to promote evaporation thereof. Vapor from the region above the liquid surface is fed to vapor condensing means adjacent the bottom of the tank for condensing the same. A condensate discharge tube extends downwardly from the condensing means for discharge of condensate therefrom. Means including a pressure head of condensate within the condensate discharge tube maintains a subatmospheric pressure within the tank to promote evaporation of liquid contained therein. A drain tube may be included which extends downwardly from the tank for use in draining sludge, froth, concentrated saline solution, or the like, from the tank. A pressure head of liquid is contained in said drain tube to maintain the tank at the subatmospheric pressure. Cold liquid adjacent the bottom of the tank may be used for external cooling purposes, if desired.

A distillation system comprising a vacuum tank at subatmospheric pressure, liquid supply means for supplying liquid to be distilled to said tank to partially fill the same, condensing means inside said tank adjacent the tank bottom for condensing vapor contained within the tank, condenser inlet mean
A distillation system comprising a vacuum tank at subatmospheric pressure, liquid supply means for supplying liquid to be distilled to said tank to partially fill the same, condensing means inside said tank adjacent the tank bottom for condensing vapor contained within the tank, condenser inlet means providing communication between said surface condensing means and the subatmospheric pressure interior of the tank above the surface of liquid partially filling the tank for passage of vapor contained within the tank above the liquid surface to said condensing means, and means for removing condensate from said condensing means while maintaining a subatmospheric pressure within the tank. In a distillation process, the elements comprising, feeding liquid to be distilled into a vacuum tank from which air is removed to partially fill the tank with said liquid, evaporating liquid fed into the tank to provide a vapor thereof within said tank, cooling vapor by condensing means located inside the vacuum tank in the liquid adjacent the bottom of the tank for condensing at least a portion of said vapor, and removing condensate from said condensing means while maintaining vapor pressure within the vacuum tank at a subatmospheric level.
