SF6 process separating unit

Yamamoto et al. investigated the SF6 gas recovery from N2/SF6 gas mixtures using polyimide hollow fiber [2]. In this study, the membrane-based separation system was applied to the enrichment of SF6 of low concentration from gaseous mixtures with nitrogen. The membrane-based separation system provides a practical way for replacing current process.
