SF6 Decomposition Disposal for powergrid

2016-2-176 Decomposition and Contamination • Reactive decomposition byproducts form when SF 6 is exposed to: 1. spark discharges, 2. partial discharges, 3. switching arcs, and 4. failure arcing • Decomposition byproducts can take the form of gas or powders • Other types of contaminants can include moisture and air

2017-10-16and effective disposal method of the present amounts of stored SF6, for possible generation of H2S and HF. Keywords: sulfur hexafluoride; metal; ammonia 1. Introduction Sulfur hexafluoride, SF6, is a colorless, nonflammable and highly inert gas with an extremely high global warming potential (GWP) [1,2].

SF6 or Sulfur Hexafluoride is a manmade specialty chemical with the highest dielectric strength among any readily available gas. This unique property allows the gas to be utilized in circuit breakers and power transformers to quench arcs, while safely protecting the electrical equipment from damage and allow for reliable

2013-12-20The SF6 decomposition reaction with SSS at 500–700 &C generated solid MF2/MF3 and gaseous SiF4, SO2/SO3 as well as HF. When 10 wt % of SSS was replaced by Fe2O3 or CaO, the SF6 decomposition amount decreased from 21.0 to 15.2 or 15.0 mg/g at 600 &C. The advantage of SSS over Fe2O3 or CaO in the SF6 decompositionCited by: 11

Our products specialize in the recovery of insulation gases - SF6 gas and SF6 gas mixture. We can easily, speedly, and safely preceed the insulation gases, to remove the moiture, impurities, decomposition in the unqualified SF6 gas. The new gas after treatment can meet the IEC standard, and realize the reuse of waste gas.
