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 ofGet price

Separation of sulfur hexafluoride (Sulfr hexafluoride) from ternary gas

Feb 15, 2014 · 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,Get price

gaz sf6 Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of insulating gasChemical Properties of gaz sf6 GasElectrical Properties of gaz sf6 Gassf 6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that sf6 gas gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very rapidly. Allied Chemical Corporation and Pennsalt were the first American industries, who began to produce this gas commercially in 1948. During 1960, using of sulfur hexafluoride gas in high voltage switchgear became popular. As the demand for this gas was increasing, many manufacturers in Europe and America started producing Sulfr hexafluoride gas in large scale, during that time. In the beginning, Sulfr hexafluoride gas was only used for the insulating purpose in the electrical system. But soon it was realized that this ga...Get price
