原始语种摘要: Abstract(#br)Results of experimental investigation of pervaporation dehydration of ethanol and isopropanol by HybSi membranes at concentrations of organic component in the feed in the range from ~50 to ~99wt%, feed temperatures 60, 70 and 80°C and permeate pressures 5 and 20mm Hg are presented. The experimental data demonstrate a nonmonotonic dependence of separation factor on water concentration in the feed with maximum value of separation factor reached at water concentration in the feed of several percent for both ethanol dehydration and isopropanol dehydration. Values of both total permeate flux and separation factor for the isopropanol dehydration case are higher than for the ethanol dehydration case. Results of the...
