Advanced membrane that minimize energy intensive phase change-driven separations can allow as much as an order of magnitude reduction in energy intensity per unit of product purified. While already used for water purification, more efficient approaches such as reverse osmosis cannot yet be used widely, due to a lack of advanced materials suitable for use with non-aqueous feeds. Recent developments in membrane materials can extend the low energy intensity separation revolution beyond water to include the full spectrum of large scale feeds. Crosslinked glassy polymers, polymer-selective nanoparticle hybrids and carbon molecular sieve (CMS) materials cover different areas in this new separation landscape. This presentation will discuss examples of these new materials, devices based on them as well as their manufacturing and the savings they enable.
