SF6 N2 Mixtures solutions with return system

The capture and separation of CF4, C2F6, and SF6 and their mixtures containing nitrogen is a challenging process. To solve this, we propose the use of saccharose coke-based carbons as membranes for the adsorption and separation of these gases. By means of advanced techniques of Monte Carlo and molecular dynamics simulations, we have studied the adsorption and diffusion of CF4, C2F6, and SF6 as ...

  • SF6 gas Mixtures emissions with return system

    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.

    The results showed that thermal properties of 20% SF6/N2 (volume fraction of SF6 is 20%) mixture has faster degradation than 40% SF6/N2 mixture. As ratio of SF6 content decreases, thermal stability of the system decreases, and the decomposition process of SF6 is exacerbated. Moreover, a mathematical model was established to determine happening of partial overheating faults on the epoxy resin surface in SF6/N2 mixture.
