2019 AIChE Annual Meeting

Session: Advances in Nuclear Separation Processes and Applications

Separations chemistry forms the backbone of nuclear materials development. This session looks for papers on keys separations process associated with nuclear processing including solvent extraction, ion exchange, filtration, gas phase adsorption, precipitation and dissolution. Papers addressing both proposed new separation processes and modifications to existing processes are encouraged.
