  • SF6 gas Mixtures unit bidding

    Separation and Concentration of SF6 from N2/SF6 Gas Mixtures For example, pure SF6 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 is to reuse by separation and recovery of SF6 of low concentration from the gases mixtures with nitrogen or air in the electric power industry.
