Controlling and Expanding the Selectivity of Filtration Membranes

Chemical separations account for about 50% of costs and energy use associated with chemical and petrochemical manufacturing, corresponding to about 10% of all energy use in the U.S. Membrane separations are highly energy efficient, simple to operate, scalable, and portable. Broader use of membranes is limited by the selectivity of available membranes, mostly confined to the separation of species about an order of magnitude or more different in...
