• Modeling and Simulation of Sulfur Hexafluoride (SF

    Abstract−Liquid sulfur hexafluoride (gaz sf6) contains carbon tetrachloride (CF4) and air as main impurities. It is very difficult to remove these impurities by using a catalyst column or an adsorption column. In this work a new puri-fication method for Sulfr hexafluoride mixture based on batch distillation is proposed. Experimental study showed good purifi-

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a de
