SF6 N2 Mixtures plants for mining

Sep 15, 2015 · A hydrothermally stable, zirconium-based metal–organic framework called UiO-66-Zr has been studied for its ability to separate SF 6 from SF 6 /N 2 mixtures. The ideal adsorbed solution theory (IAST)-predicted selectivities based on single-component isotherms and the dynamic breakthrough calculations for mixture conditions demonstrate that UiO-66-Zr can effectively separate SF 6 /N 2 mixtures.

  • N2/SF6 gas Mixtures — Large Scale Application in Gas

    The application of N 2 /SF 6 gas mixtures with SF 6 -contents between 10 % and 20 % reduces the costs for the insulating gas remarkably. This is of great importance when GIL is to be used for long distance bulk power transmission. By this, also the acceptance for long distance applications of this technique is improved on the user side.

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.
