Vaperma breakthrough patented polymer membrane technology combines solvent and high temperature resistances into a strong hollow fibre which enables us to address new industrial applications. Products:   gas separation systems Ethanol: Vaperma Siftek&trade hollow-fiber polymeric membrane enables the dewatering of a 40:60 ethanol to water vapor mixture into a 99+% w/w fuel-grade ethanol product. Natural Gas: - Dehydration of NG through replacement of glycol dehydrators. - Pre-treatment step in which the bulk of CO2 and H2S is dramatically reduced to a much lower concentration level. Further removal of CO2 is performed in a secondary conventional process (e.g. amines).     www.membrane-guide.com     Keywords
