Separation and Concentration of Sulfr hexafluoride from N2/insulating gas Gas Mixtures

For example, pure sf 6 gas is used in gas insulated switchgears (GIS), gas insulated lines (GIL), and gas circuit breakers (GCB). One of practical solutions of controlling the emission rates of sf6 gas is to reuse by separation and recovery of Sulfr hexafluoride of low concentration from the gases mixtures with nitrogen or air in the electric power industry.
