mobile SF6 N2 Mixtures separating 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.

  • Separation of CF4/N2, C2F6/N2, and SF6/N2 Mixtures in

    The capture and separation of CF 4, C 2 F 6, and SF 6 and their mixtures containing nitrogen is a challenging process. To solve this, we propose the use of saccharose coke-based carbons as membranes for the adsorption and separation of these gases.

  • Separation of SF6 from Gas Mixtures Using Gas Hydrate

    Furthermore, the structure of the mixed N2 + SF6 hydrate was confirmed to be structure II via Raman spectroscopy. Through close examination of the overall experimental results, it was clearly verified that highly concentrated SF6 can be separated from gas mixtures at mild temperatures and low pressure conditions.

  • Efficient SF6/N2 separation at high pressures using a

    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.
