Abstract

This study was performed to investigate whether the decomposition process of $SF_6$ using an electron beam is economically reasonable when applied to the actual field. To do this, electron beam experiment and economic analysis were conducted. The experiment conditions are initial concentration of 1% of $SF_6$, 1 mA of input energy and 15 mA of flow rate with $H_2$ as an additive which were obtained from our previous research. As a result, removal efficiency of $SF_6$ was 90% for 8 hours continuously. In addition, economic analysis shows positive results in terms of using $SF_6$ decomposition process using electron beam. According to the analysis, the revenue is approximately 1.66 billion won in the first year and 3 billion won in the second year.
