  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

  • Separation of sulfur hexafluoride (SF6) from ternary gas

    The separation of sulfur hexafluoride (SF 6 ), a powerful anthropogenic greenhouse gas, was investigated using membrane technology. Permeation measurements in commercial polysulfone (PSf) hollow fiber membranes were performed using single gases (i.e. N 2, O 2 and SF 6) to investigate the effect of temperature and pressure on separation performance. The permeation experiments of ternary gas mixtures (N 2 /O 2 /SF 6) were also conducted under various operational conditions, including pressure,
