Permeation and separation under high temperature and high pressure for ethanol/water vapors through cross-linked quaternized chitosan composite membranes
... other was membrane A further cross-linked in an aqueous GA solution with a H2SO4 catalyst (membrane B). These membranes were then applied to the dehydration of ethanol/ water mixtures for high temperature and high pressure evapomeation (HTPEV). The permeation flux increased with increasing feed vapo ...

Comparative study of commercially available polymeric and microporous silica membranes for the dehydration of IPA/water mixtures by pervaporation/vapour permeation
... commercially available polymeric and microporous silica membranes (both supplied by Sulzer Chemtech GmbH) was investigated with respect to the dehydration of binary mixtures of isopropyl alcohol (IPA)/water. The range of concentrations investigated (CH2O # 20 wt.%) was selected according t ...
