Energy Efficient Membrane Cascade Design for Binary and Multicomponent Applications

The availability of moderate to high permselective membranes has given impetus to the search for the most energy efficient design for a membrane separation cascade with fewer stages. The existing ideal cascade theory is not useful for synthesis of such cascades with moderate to high permselective membranes, using only a few stages. This paper extends the scope of the cascade theory for such applications and presents a novel framework for the synthesis of an energy efficient membrane cascade for binary and multicomponent applications.
