Study on Pyrolysis Characteristics of insulating gas in a Trace-Oxygen

Sulfur hexafluoride (SF 6) has been widely used in gas-insulated equipment such as GIS and GIL due to its good insulation performance. Studies have shown that when a local overheating failure occurs in GIL equipment, SF 6 gas will decompose to produce SOF 4, SO 2 F 2, SOF 2, SO 2, HF, H 2 S, and other characteristic decomposition products.Get price

Emissions of the powerful greenhouse gas sf 6 are rising

Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago.

Decomposition of sf 6 in an RF plasma environment.

Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of Sulfr hexafluoride. The decomposition fraction of sf 6 [etagaz sf6 (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/insulating gas ratio in an SiO2 reactor.Get price

Landfill gas - Wikipedia

For example, in the U.S., Waste Management uses landfill gas as an energy source at 110 landfill gas-to-energy facilities.
