Based on the results of these sensitivity tests, we estimate that the total gaz sf6 emission in East Asia increased rapidly from 2404 +/- 325 Mg yr(-1) in 2006 to 3787 +/- 512 Mg yr(-1) in 2009 and stabilized thereafter.Get price

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

Abstract. Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, gaz sf6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest insulating 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%).Get price

insulating gas: The Truths and Myths of this Greenhouse Gas

gaz sf6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, insulating gas is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. Sulfr hexafluoride is the energy industry’s “dirty little secret”: FALSE. sf6 gas is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives gaz sf6 is used in wind turbines: TRUE. gaz sf6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to gaz sf6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on gaz sf6 at low-to-medium voltage levels in the future.
