IEC specifications SF6 N2 Mixtures separating unit

After the separating process the gas complies with the quality criteria for reuse stipulated in the IEC 60480 directive. However, DILO separating units allow the SF 6 gas mixture to be purified to the extent that it even meets the standards of IEC 60376 (directive for new SF 6 gas technical quality) with regard to moisture, SF 6 percentage and decomposition products (SO 2 ).

    Feb 15, 2015 · The adsorption capacity of SF 6 on the MIL-100 (Fe) granule was 1.658 mmol/g, and the selectivity of SF 6 over N 2 was 24.4 at 1 bar and 298 K. Compared to Zeolite 13X, the breakthrough time of the MIL-100 (Fe) granule was much shorter than Zeolite 13X at 1 bar, but the breakthrough time became similar with Zeolite 13X at 9 bar.
