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.
Apparatus for the separation of solutions by pervaporation, said apparatus comprising means defining at least one raw solution chamber for the reception of raw solution, means defining a pervaporation chamber disposed adjacent said raw solution chamber, a membrane disposed between said raw solution chamber and said pervaporation chamber so as to permit evaporation of part of said solution through said membrane into said pervaporation chamber from which the vapors are removed, and heating means associated with said raw solution chamber so as to transmit heat to the raw solution therein for replenishing in said raw solution the heat consumed by pervaporation of part of said solution through said membrane into said pervaporation chamber, said raw solution chamber having circumferential side walls with one of two oppositely disposed side walls having means defining a plurality of closely spaced raw solution supply openings and the other of said two oppositely disposed side walls having means defining a plurality of closely spaced raw solution discharge openings representing means for generating within said raw solution chamber an essentially laminar flow of raw solution in a direction from said supply openings to said discharge openings and said pervaporation chamber having circumferential side walls with two opposite side walls oriented essentially at an angle of 90.degree. with respect to the orientation of said oppositely disposed raw solution chamber side walls and said two pervaporation chamber side walls having means defining a plurality of closely spaced blowdown openings for rapid and efficient removal of the pervaporate from the pervaporation chamber in a direction normal to the flow direction of the raw solution through the raw solution chamber and for avoiding mixing of pervaporate of different concentrations.
