recover SF6 N2 Mixtures solutions

SF6 gas. Sulfur hexafluoride - SF6 is an industrially produced gas with excellent dielectric and arc quenching properties. The gas is mainly used as insulation and breaking medium in e.g. switchgear, transformers and switches for high and medium voltage. SF6-filled electronic equipment are closed systems that provide no direct emissions.

  • SF6 Gas Recovery from SF6 / N2 Mixtures Using Polymer

    One of the plausible methods is to recover SF 6 as liquid using the difference in boiling point between gas species in the mixture. However, it has been pointed out theoretically that the recovery loss by this method is very large when SF 6 content in the mixture is lower than ~50 vol.% 1 ).

  • Separation and Concentration of SF6 from N2/SF6 Gas Mixtures

    In the case of a gas mixture that includes a low concentration of SF6, the liquefaction method is difficult to apply due to its low boiling point (-60°C). By using membrane separation and pressure swing adsorption (PSA) method, SF6can be recovered from gaseous mixture with low SF6 content. There have been little reports on the separation of N2/SF6 gas mixtures using the membrane-based system.
