ABSTRACT:

Poly (vinyl alcohol) membranes were prepared by in-situ crosslinking of poly (vinyl alcohol) with glutaraldehyde as a crosslinking agent and hydrochloric acid as catalyst and the membranes were used to separate mixtures of IPA and water. Effects of feed composition, operating temperature, vacuum pressure and Reynolds number on permeation performance of the membranes were evaluated. The results showed that operating conditions have an effective influence on permeation properties of PVA membranes.

KEYWORDS:

PVA membrane; Pervaporation; Crosslinking; Separation factor
