PURIFICATION OF ORGANIC COMPOUNDS BY MEMBRANE PERMEATION

Abstract

This report presents data obtained during a study of liquid-phase membrane permeation in which the effects of various operating conditions, charge mixtures, and film properties were examined. Selected binary mixtures were permeated through thin, non-porous, plastic films and the permeation rate and selectivity of the system recorded. It was found that perm-selectivity increased and permeation rate decreased as the crystallinity or density of hydrocarbon films was increased. The effect was most consistent when hydrocarbon vinaries were used. Permeate pressure was found to have a marked effect on selectivity and some influence on rate. Permeant pressure also affected selectivity and rate but less than permeate pressure. The magnitude and direction of both of these pressure effects varied with the type of film employed.
