  • Separation of SF6 from Gas Mixtures Using Gas Hydrate

    Jul 27, 2010This study aims to examine the thermodynamic feasibility of separating sulfur hexafluoride (SF6), which is widely used in various industrial fields and is one of the most potent greenhouse gases, from gas mixtures using gas hydrate formation. The key process variables of hydrate phase equilibria, pressure−composition diagram, formation kinetics, and structure identification of the mixed gas

  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • Breakdown in Compressed HE/SF6 Gas Mixtures in Uniform Field

    The breakdown strengths in uniform field were calculated for helium/SF6 mixtures at pressures up to 300 kPa for smooth electrodes, and compared with measured values. The effect on discharge thresholds in He/SF6 mixtures due to the polarity of an artificial protrusion and due to irradiation of the gap was investigated. The results obtained from this study show that the calculation of the

  • A review on SF6 substitute gases and research status of

    Nov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.

  • Comparison of the Breakdown Strength of N2, CO2 and SF6

    SF6 is often used as insulating medium. Due to the fact that SF6 is a greenhouse gas with a very high global warming potential (GWP), alternatives have been searched for over the last years. In particular, SF6/N2 gas mixtures have been extensively investigated for the use in Gas Insulated Lines (GIL) and is being used in several applications.
