Pervaporation Membrane System Schematic
This process flow schematic illustrates a pervaporation membrane system setup. A feed pump circulates liquid from a feed tank through a heat exchanger and into a pervaporation membrane module, with recirculation and sampling loops. A vacuum system, consisting of a vacuum pump, trap, and impingers, maintains the pressure gradient required for permeation across the membrane.
