What is the importance of sulfur hexafluoride recovery and purification?Sulfur hexafluoride gas is an ideal insulating gas and is widely used in power systems.

　　SF6 gas is also a greenhouse gas.According to EPA and IPCC reports,in 1998,the United States emitted SF6 gas equivalent to 10 million tons of carbon dioxide,most of which was directly emitted by power companies without sulfur hexafluoride recovery and purification.

　　In 1994,65,800 tonnes of sulphur hexafluoride gas were emitted globally,of which 20 per cent came from the production of magnesium and 80 per cent from the consumption of insulators and high-voltage converters.This makes sulfur hexafluoride recovery and purification extremely urgent.

　　At present,sulfur hexafluoride manufacturers are actively conducting research on SF6,especially SF6 gas recycling and SF6 leakage detection technology.For more information,call 139-4929-0069.
