Abstract

$SF_6$ (sulfur hexafluoride) gas has an extremely high global warming potential (GWP) because of strong absorption of infrared radiation and long atmospheric lifetime which cause the global warming effect. The objective of this study is to identify the effects of destruction and removal efficiency (DRE) of $SF_6$ by the addition of oxygen, water vapor and hydrogen. The applied dose of ionization energy was 1,028 kGy(5 mA). The initial concentrations of $SF_6$, $O_2$, $H_2O$ and $H_2$ gases were 1,000 ppm, 1,000 ppm, 3,000 ppm, 3,000 ppm, respectively. The DRE was increased about 2 times with $O_2$ gas injection. The $SF_6$ was completely removed with $H_2O$ and $H_2$ gas injection. By-products formed by $SF_6$ destruction were mainly HF and $F_2$ gases. In addition, $SF_2$, $NF_3$, $H_2O$, $SO_2$, $SO_2F_2$, and $NO_2x$ gases were produced.
