Potent GHG sf 6 rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, sf 6 is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.

Abstract: Sulfur hexafluoride (gaz sf6) has a global warming potential of around 22 800 over a 100-year time horizon and is one of the greenhouse gases regulated under the Kyoto Protocol. Around the year 2000 there was a reversal in the global sf6 gas emission trend, from a decreasing to an increasing trend, which was likely caused by increasing emissions in countries that are not obligated to report their annual emissions to the United Nations Framework Convention on Climate Change.

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 fugi

Sulfur Hexafluoride (sf 6) | Encyclopedia.com

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