报告人简介：

Dr. Feng is a University Research Chair and Professor of Chemical Engineering at the University of Waterloo. He is internationally renowned for his work on membranes and separation processes. He has been on the Editorial Boards of Journal of Membrane Science and Separation & Purification Technology, the premier journals in the field. He also serves as a Subject Editor for Chemical Engineering Research & Design. Among others, he has developed a membrane-based olefin-paraffin separation technology which is being commercially exploited. His research to date has resulted in 11 patents, 150+ papers in peer-reviewed journals, and numerous conference presentations (including Plenary Lectures and Keynote presentations) and seminars/lectures at companies and research institutions worldwide. He is a recipient of the Premier’s Research Excellence Award (2005), the University of Waterloo Outstanding Performance Awards (2006, 2010 & 2014), and the University of Waterloo Faculty of Engineering Distinguished Performance Awards (2002, 2005 & 2013).

   A novel process of gas separation by membranes based on pressure swing permeation will be presented. In one case, two or more membrane modules are synchronized, and each module undergoes sequential steps of feed admission and permeation, residual removal, permeate reception, and permeate pressurization. The permeate at a pressure close to the feed pressure can be produced without using a compressor, which is otherwise impossible to achieve with the traditional steady-state permeation process where a pressure difference across the membrane must be maintained. This process has the potential to integrate synergistically with pressure swing adsorption for enhanced separations. In another process mode, feed pressurization and permeate evacuation are achieved in a cyclic fashion to increase the transmembrane pressure difference and the feed to permeate pressure ratio. To exemplify the feasibility and effectiveness of the cyclic processes, hydrogen purification, air separation for oxygen enrichment, and CO2 capture from flue gas by pressure swing permeation are evaluated.
