  • Separation of SF6 from Gas Mixtures Using Gas Hydrate

    This study aims to examine the thermodynamic feasibility of separating sulfur hexafluoride (SF6), which is widely used in various industrial fields and is one of the most potent greenhouse gases, from gas mixtures using gas hydrate formation. The key process variables of hydrate phase equilibria, pressure−composition diagram, formation kinetics, and structure identification of the mixed gas hydrates, were closely investigated to verify the overall concept of this hydrate-based SF6

  • (PDF) CAPTURE AND RECYCLE FOR EMISSION REDUCTION OF SULFUR

    In air separation applications, nitrogen is the “slow,” non-permeable gas and oxygen is the “fast,” permeable gas. However, for the SF6 capture application, both nitrogen and oxygen (i.e., air) are fast-permeating species. This is due to the fact that both nitrogen and oxygen have a much smaller kinetic diameter than SF6 (Table 2).
