smartGAS SF6 N2 Mixtures device

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.

  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables. Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900).
