SF6 N2 Mixtures separating unit dilo

May 01, 2019 · N 2 /SF 6 mixtures have been widely used in gas-insulated equipment. Highly efficient separation approaches are urgently required to recycle SF 6 from the mixtures during equipment maintenance. Gas separation with glassy polymeric membranes is regarded as a promising approach due to the great size difference between SF 6 and N 2 molecules.
