Summary
The pervaporation of binary mixtures through moderately swollen membranes is analyzed as a’ solution-Diffusion’ process and on the assumption that the diffusivity of each permeant is an exponential function of both concentrations. A model is derived, in which changes in selectivity and fluxes are related to major external conditions: the upstream mole fraction in the feed and the downstream total pressure of the pervaporate. In order to test the validity of this model, it has been applied to a set of experimental data for the pervaporation of hydrocarbon binary mixtures through rubber membranes.
