• Removes sulfides
  • Uses unique combination of iron oxides react with sulfides (H2S) to produce iron sulfide. An activator oxide catalytically enhances the reactive adsorption phenomenon: Fe3O4/Fe2O3(s) + H2S(g) + FeS2(s) + H2O(l)
  • Can be single vessel or lead/lag with 2 vessels in series
  • Reaction times are relatively slow in comparison to conventional carbon or alumina systems
