Sulfur hexafluoride - Wikipedia

It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year.Get price

Green Gas to Replace sf 6 in Electrical Grids | IEEE Journals

Apr 12, 2016 · Not least among the major concerns are global warming and the greenhouse gases that contribute to it, as their concentration in the air reaches new heights. Hence the power industryfocus on sulfur hexafluoride (SF 6 ) and the need to find a suitable alternative for it in industrial applications. Grid Solutions, a GE and Alstom joint venture, has identified a fluoronitrile based gas mixture dubbed g 3 -green gas for grid-that is such a alternative.Get price
