The permeation characteristics of the commercial polymeric membrane PERVAP ® 2201 were studied to carry out the dehydration of binary water/isopropanol mixtures. The influence of the composition (2-75 wt % H 2 O) and temperature of the feed (311.15-348.15 K) on the membrane performance was studied. The selected membrane showed a high selectivity towards water in the entire concentration range. It was found that the permeation rate increased with the water content and the operating temperature. The influence of the temperature on the flux can be described by an Arrhenius-type expression. The commercial software Aspen Plus was used to simulate the dehydration of isopropanol by means of a hybrid process combining distillation and pervaporation.

“…Since the dewatering of organic solvents, and more specifically of low molecular weight alcohols, is the most common application, there are many publications on the separation of ethanol-water mixtures (Kim et al, 2000;Ni et al, 2001;Nomura et al, 1998;Wesslein et al, 1990) and the separation of IPA-water mixtures (Gallego-Lizon et al, 2002;Hilmioglu and Tulbentci, 2003;Wesslein et al, 1990). However, these mixtures are mostly used as a "standard test" to evaluate a newly developed or synthesized membrane.…”
