Abatement of Sulfur Hexafluoride Emissions from the

Reduction of greenhouse gas emissions has become a worldwide issue. Two kinds of nonthermal plasmas—DBD and CPC—were used to abate SF 6 molecules emitted from semiconductor manufacturing processes. As much as 91% of SF 6 removal efficiency could be achieved with DBD. Four additives (Ar, O 2,C 2H 4, and H 2O) for enhancing SF 6 abatement also were investigated.

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
