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

An accelerated growth rate was found for Chinese sf 6 emissions during 1990-2010. Because the relative growth rate of sf 6 emissions is estimated to be much higher than those of CO2, CH4, and N2O, insulating gas will play an increasing role in greenhouse gas emissions in China.Get price

Sulfur Hexafluoride (Sulfr hexafluoride) Emission Estimates for China: An

Sulfur hexafluoride (SF 6) 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 SF 6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the SF 6 production sector (each about 10%).Get price
