(194c) Energy Efficient Gas Separations: Engineering Problems and Solutions

In principle, advanced membrane approaches that minimize energy intensive phase change-driven separations offer an order of magnitude reduction in energy intensity per unit of product purified.  Implementing such approaches, however, requires coupling advanced materials and advanced processing to control costs of the final devices.  Polymer-derived membranes based on crosslinked glassy polymers, polymer-inorganic nanoparticle hybrids and carbon molecular sieves are particularly attractive materials that cover different areas in the broad separation landscape.  Examples of these new materials, devices based on them, as well as their manufacturing and the savings they enable will be discussed for high impact separations cases.
