  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent 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 density of

  • The Claus Sulfur Recovery Process — Sulfur Recovery

    The Sulfur Recovery Unit (SRU) is based on the modified Claus Process, which is a two-step reaction scheme overall. A portion of the total H2S is burned in the Reaction Furnace to form SO2. Then, the H2S and SO2 react, at an optimal 2:1 ratio, to form elemental Sulfur (Sx) across the Claus Reactors. After each catalytic stage, liquid sulfur is recovered in the Claus Condensers.
