Sulfur Hexafluride (sf 6) Replacement or Reduction in high

Abstract. Sulfur Hexafluoride (sf6 gas) is a gaseous dielectric used for suppression of high-voltage breakdown by the electric power industry and airborne military radar systems, including the Airborne Warning And Control System (AWACS). Sulfr hexafluoride is chemically inert and a very efficient infrared (IR) absorber, which make it a very potent greenhouse gas (GHG) whose impact on global warming is estimated to be 24,000 times greater than CO2.Get price

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air. It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugiGet price

Sulfur Hexafluoride (Sulfr hexafluoride) | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula sf 6) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and Sulfr hexafluoride—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although sf6 gas is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. Sulfr hexafluoride is one of the six greenhouse gases regulated under the Kyoto Protocol.Get price
