    Feb 15, 2015 · To overcome this obstacle, Kwon et al. performed an SF 6 /N 2 separation (1.3 vol.% SF 6) using the pressure temperature swing adsorption (PTSA) process to desorb SF 6 efficiently. They obtained an SF 6 purity of 19.5% and a recovery of 50.1% at a 2.5 atm adsorption pressure and a 200 °C desorption temperature.

  • Continuous distillation - Wikipedia

    Since a continuous distillation unit is fed constantly with a feed mixture and not filled all at once like a batch distillation, a continuous distillation unit does not need a sizable distillation pot, vessel, or reservoir for a batch fill. Instead, the mixture can be fed directly into the column, where the actual separation occurs.

    Feb 20, 2001 · An SF6/N2 mixture co ntaining about 1% by volume SF6 was passed over two adsorbers connected in series, which contained a bed of 500 ml of the respective adsorbent. The mixture was passed through until about 10 g SF6 had been passed through. The mixture leaving the second adsorber was investigated using gas chromatography, and the SF6 concentration was determined. The first series of tests was carried out at ambient pressure (1 bar).

    N2 - Adsorptive separation of SF6/N2 mixtures is an important issue since SF6 is a significant greenhouse gas. Although separation performances should be evaluated under high pressure conditions to find an efficient adsorbent candidate for pressure swing adsorption (PSA) processes, no studies on metal–organic frameworks (MOFs) have focused on SF6/N2 separation at high pressures above 1 bar.
