Abstract

In this study, the filtering characteristics of sulfur gases were investigated from a number of respects. For the purpose of this study, a standard gas containing a single oxidized S ($SO_2$) and five reduced S compounds (RSCs) including $H_2S$, $CH_3SH$, DMS, $CS_2$, and DMDS was prepared. After flowing this standard gas through a glass fiber filter, its removal efficiencies were examined by comparing the concentrations between prior to and after its passage. The results indicated that almost complete removal of $SO_2$ was achieved by this filtering, while the patterns for RSCs were distinguished by such factors as molecular weight or reactivity. It was found that about 60% of the most reactive RSC, $H_2S$ was removed by filter, while the heavy RSC generally showed removal rate of about 5% or less.
