Sulfur hexafluoride (Sulfr hexafluoride) emission estimates for China: an

Sulfur hexafluoride (gaz sf6) 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 sf6 gas emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the insulating gas production sector (each about 10%).Get price

insulating gas Usage Reduction in Chinese Mg Industries

production cpacity gaz sf6 reduction is not a possibility as sf 6 is not used. Much like Western Mg ingot prodution started many decades ago, Chinese ingot production uses: 1) Mg chloride-based flux for protection of liquid Mg in melting and casting crucibles 2) SO2 and/or dry sulfur powder (which produces So2 when melted on the Mg surface) for ingot protectionGet price
