Sulfur hexafluoride (sf6 gas) emission estimates for China: an

Abstract. Sulfur hexafluoride (sf6 gas) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, sf 6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest sf6 gas emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the sf6 gas production sector (each about 10%).

conclusions regarding emission factors for the 1990s. If high emission factors were prevalent, SF 6 emissions from the production sector in the 1990s in China may have been underestimated in this study, but this did not greatly affect total emissions, because production-related emissions only accounted for about 10% of the total emissions.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

Abstract: Sulfur hexafluoride (insulating gas) 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 Sulfr hexafluoride 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.
