Nanoporous Membranes for Extreme Operating Environments

Sankar Nair

Although nanoporous membranes have seen great interest for gas and hydrocarbon separations, membranes for more extreme operating environments are also a major emerging research effort and require a different set of strategies. In this talk, I will describe our recent progress with three “short stories” from the areas of biomass processing and nuclear fuel recycling. The first one concerns the development and scaling-up of graphene oxide (GO) membranes for dewatering of black liquor, a major by-product of biomass processing in the pulp and paper sector. Key considerations include the membrane stability in corrosive alkaline black liquor streams, and the separation of a range of components with widely different molecular weights. The second concerns the development of hollow-fiber supported zeolite membranes for recovery of noble gas isotopes (85Kr – radioactive waste) and (136Xe – valuable industrial gas) during the reprocessing of used nuclear fuel. The third example concerns the removal of tritium and deuterium from aqueous mixtures using zeolitic membranes, and the design of zeolite membrane processes for tritium removal. Key issues pertaining to the latter two separations process include miniaturization of membrane size, resistance to acidic and radioactive environments, and use of membranes for separating components with very low transport driving forces.
