The decomposition products of sulfur hexafluoride (insulating gas

From the environmental and health points of view, it is necessary to mitigate and control the emissions of the decomposition products from SF 6 destruction processes because most of them (e.g. S 2 F 10, SF 4 and HF) are highly reactive, corrosive and toxic, and few of them are also potent GHGs. This article aimed to introduce the fullyGet price

insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf 6 as an insulating gas has led to many studies on sf 6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, insulating gas decomposes to a wide variety of chemically active products which possess completely different properties from sf 6.Get price

Decomposition of Sulfr hexafluoride in an RF Plasma Environment

insulating gas was not affected by the feed O 2 /SF 6 ratio, lead-ing to more than 99% decomposition. Reaction Products The major reaction products of the decomposition of SF 6 were SiF 4, SO 2, F 2, SO 2 F 2, SOF 2, and SOF 4. The applied power was the most important factor that limited the production of all species.13 The mole fraction of SiF 4 in-Get price

Sep 20, 2019 · It likely forms via an electrically induced decomposition reaction of SF 6: 2 SF 6(g) → S 2 F 10(g) + F 2(g) S 2 F 10 has a toxicity four times that of phosgene, COCl 2! In WWII, gaseous S 2 F 10 was considered a chemical warfare pulmonary agent. Its toxicity emanates from the disproportionation reaction: S 2 F 10(g) → SF 6(g) + SF 4(g)Get price
