  • Application and Recycling of SF6 gas Mixtures in Gas

    As a result, the SF6/N2 mixture gas is gradually replacing the SF6 gas in extra/ultra-high voltage transmission systems [21][22] [23]. For example, the insulation performance of SF6/N2 has already

  • Separation and Recovery of $SF_6$ Gas from $N_2/SF_6$ Gas

    Under the condition of P=0.5 MPa, the highest concentration of recovered SF6 is 95.6 vol % in the separation experiment of SF6/N2 mixture gas by PC membrane. Under the operation pressure of P=0.3 MPa at a fixed retentate flow rate fixed of 150 cc/min, the maximum recovery efficiency of SF6 is up to 97.8% by PSF membrane.

  • Dielectric properties of C5-PFK mixtures as a possible SF6

    C5-PFK has attracted much attention as one of the most promising SF6 substitutes for medium voltage (MV) power equipment because of its high insulation strength and low global warming potential (GWP). In this paper, the dielectric properties of C5-PFK-Air and C5-PFK-CO2 mixtures are experimentally investigated, to explore the most effective solution for C5-PFK mixtures for application in MV

  • CALCULATION OF SPARKING POTENTIALS OF SF6 AND SF6-GAS

    Abstract. A simple formula is developed to predict the sparking potentials of SF6 and SF6-gas mixture in uniform and non-uniform fields. The formula has been shown to be valid over a very wide range from 1 to 1800 kPa-cm of pressure and electrode gap separation for mixtures containing 5 to 100 % SF6.

  • Separation of SF6 from Gas Mixtures Using Gas Hydrate

    The three-phase equilibria of hydrate (H), liquid water (LW), and vapor (V) for the binary SF6 + water mixture and for the ternary N2 + SF6 + water mixtures with various SF6 vapor compositions (10, 30, 50, and 70%) were experimentally measured to determine the stability regions and formation conditions of pure and mixed hydrates.
