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 (<TEX>$SO_2$</TEX>) and five reduced S compounds (RSCs) including <TEX>$H_2S$</TEX>, <TEX>$CH_3SH$</TEX>, DMS, <TEX>$CS_2$</TEX>, 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 <TEX>$SO_2$</TEX> 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, <TEX>$H_2S$</TEX> was removed by filter, while the heavy RSC generally showed removal rate of about 5% or less.
