Abstract
An apparatus for the separation of solutions by pervaporation includes a raw solution chamber through which a raw solution is conducted from which a part is to be separated, a permeation chamber disposed adjacent the raw solution chamber but separated therefrom by a membrane which permits evaporation therethrough of part of the solution into the permeation chamber from which the vapors are removed, a heating structure arranged adjacent the raw solution chamber in direct contact with the raw solution therein for replenishing to the solution the heat consumed by pervaporation of part of the solution through the membrane. The raw solution chambers have closely spaced solution supply and discharge openings along opposite walls to provide laminar flow therethrough in one direction and the pervaporation chambers have discharge openings closely spaced along opposite side walls oriented normal to the orientation of the raw solution supply and discharge openings so as to rapidly remove from the pervaporation chamber any pervaporate and to remove it in a direction normal to the flow direction of the raw solution through the raw solution chamber.
