    sensors for gas-insulated switchgears (GIS) The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables. Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900).

    Feb 15, 2015 · To overcome this obstacle, Kwon et al. performed an SF 6 /N 2 separation (1.3 vol.% SF 6) using the pressure temperature swing adsorption (PTSA) process to desorb SF 6 efficiently. They obtained an SF 6 purity of 19.5% and a recovery of 50.1% at a 2.5 atm adsorption pressure and a 200 °C desorption temperature.
