• 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

    Apr 05, 2016 · As shown in Fig. 10a, the sulfuric acid dew point temperature decreases with the increase of the quantity of fly ash particles in flue gas under the same fly ash particle size. Among the five cases, the sulfuric acid dew point temperature achieves the lowest at the tail of fin when the fly ash quantity is 1.65 × 10 −2 kg⋅m −3. And it is about 2 K lower than that of the flue gas without any fly ash particles.
