rental SF6 N2 Mixtures unit

N2 - The separation of sulfur hexafluoride (SF6), a powerful anthropogenic greenhouse gas, was investigated using membrane technology. Permeation measurements in commercial polysulfone (PSf) hollow fiber membranes were performed using single gases (i.e. N2, O2 and SF6) to investigate the effect of temperature and pressure on separation performance.

  • 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.
