KEPCO Develops sf 6 Recycling Device to Combat Greenhouse Gas

Korea Electric Power Corp. (KEPCO) announced on July 9 that it has developed a sulfur hexafluoride (gaz sf6) refining device which recycles insulating gas emissions from discarded shutters and transformers. Sulfr hexafluoride is a greenhouse gas whose global warming effects are 23,900 times those of carbon dioxide. gaz sf6 is used as an insulation material for high voltage power equipment due to its electrical insulation property.

Sulfur hexafluoride - Wikipedia

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".

Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

The increasing application of sf 6 as an insulating gas has led to many studies on gaz sf6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, sf 6 decomposes to a wide variety of chemically active products which possess completely different properties from Sulfr hexafluoride. The accumulation of these decomposition products in the equipment has caused concerns regarding

Sulfur Hexafluoride (gaz sf6) | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula insulating gas) 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 gaz sf6 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.
