  • SF6 gas handling - DILO

    A service cart enables the recovery of the SF 6 gas from a gas compartment to a final vacuum of < 1 mbar. Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.

  • Separation efficiency and equilibrium recovery ratio of SF6

    Feb 01, 2021 · The hydrate-based method yielded a higher equilibrium recovery ratio of SF 6 at a given initial SF 6 concentration and required a lower pressure to yield a specified recovery ratio of SF 6 compared with the liquefaction method but showed lower SF 6 purity. The hydrate-liquefaction combined method was suggested to supplement the drawbacks of each method and conserve power consumption for pressurization.
