Abstract
Abstract A vapor generating and recovering apparatus for separating one component from a second component of a liquid solution and recovering the first component including at least one chamber for generating vapor from the liquid solution and recovering the vapor in a liquid form, the vapor generating portion of the chamber being in heat emitting relation with a heat emitting means and the vapor recovering portion chamber being in heat absorbing relation with a heat absorbing means. A preferred system for providing heat to the vapor generating portion of the chamber and removing heat from the vapor recovering portion of the chamber is a refrigerating system which includes condensing coils and evaporating coils in heat transfer relation with the vapor generating and vapor recovery chamber.
