  • B121R12 /N separating plant - DILO

    The gas mixture is compressed by a compressor, pre-cooled via a heat exchanger and purified from moisture and dust particles by a filter unit before passing into the separating tank. The gas separation is based on the SF 6 condensation at low temperature principle and is carried out in two stages resulting in high gas purity and low loss of SF 6.

    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.
