toshiba SF6 N2 Mixtures plants

As a promising alternative for pure SF6, the mixture of SF6/N2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure SF6. But less attention has been paid to the thermal properties of an SF6/N2 mixture, especially with insulation materials overheating happening simultaneously. In this paper, thermal decomposition properties ...

    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 SF6 and N 2 molecules.
