Title of Process/ Know-how/ Product/Design/Equipment
Composite hydrophilic pervaporation membrane for alcohol-water separation
Application/Uses/Problem being addressed
For production of absolute ethanol from ethanol-water azeotrope mixture while the hydrophobic membrane is for enrichment of alcohol concentration from water-alcohol mixture (0.1-10% alcohol)
Salient Technical Features including Competing Features/ Impact
Permselective hollow fiber composite comprising of top hydrophilic layer and bottom support layer for production of fuel grade ethanol (> 99 %) from ethanol-water azeotrope mixture; 2. Organophilic hollow fiber polymer membrane system with the top organic-selective layer and bottom porous support characterized by the selective alcohol permeate flux for enrichment of alcohol concentration from water-alcohol mixture
