SF6 decomposition DETERMINATION HAUG

SF6 decomposition DETERMINATION HAUG

Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

  • HAUG Decomposition

    HAUG Decomposition. Jan 22, 2013The stoichiometric demand for oxygen can vary from about 1.0 g O2 /g BVS for highly oxygenated feedstocks like cellulose or starch to 4.0 g O2 /g BVS for some hydrocarbons (Haug, 1993). Because air contains 23.2 percent oxygen by weight, the air demand is the oxygen demand divided by 0.232.
