  • Separation of SF6 from SF6/N2 mixture using metal–organic

    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 . However, a temperature swing in the adsorption separation processes increases energy consumption and the cost of equipment needed to control the temperature.

    Adsorptive separation of SF 6 /N 2 mixtures is an important issue since SF 6 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 SF 6 /N 2 separation at high pressures above 1 bar.
