Findings from University of Porto in the Area of Purification Technology Reported

June 17, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Purification Technology are presented in a new report. According to news originating from Oporto, Portugal, by VerticalNews correspondents, research stated, "The pervaporation performance of a commercial silica membrane (Pervatech BV) was evaluated for dehydration of aqueous n-butanol solutions."

Our news journalists obtained a quote from the research from the University of Porto, "The influence of the operation parameters, such as feed composition, temperature and permeate pressure was experimentally investigated in terms of permeation flux, separation factor, permeance and membrane selectivity. The membrane exhibited high flux, 3.53 kg/ m(2) h, combined with a separation factor equal to 150, at 70 degrees C and for 10 wt.% water in feed."

According to the news editors, the research concluded: "The mole fraction of water in the permeate ranged from 98.7% to 99.2% at 70 degrees C. The information collected is of most importance to design and optimize a pervaporation process for the dehydration of n-butanol, which can be integrated with an intensified technology, the simulated moving bed reactor, used in the synthesis of the green fuel, 1,1-dibutoxyethane."
