Hi, 

 

I was just looking for some advice on the removal of H2S. We have H2S in small concentrations (400-600ppmv) and Mercaptans (700-900ppmv). We are looking for a medium for removal such as a Zinc Oxide bed due to the low concentrations meaning an amine plant is not viable. I was looking for a catalyst that is capable of dealing with both H2S and Mercaptans with as little treatment as possible perhaps with the catalyst supplier dealing with regeneration. Any help would be greatly appreciated.

Zinc Oxide process is seeing decreasing use due to increasing disposal problems with the spent bed, which is classified as a heavy metal salt.

 

Iron Oxide (Iron Sponge) or Sulfatreat process has lesser disposal problems compared to Zinc Oxide. Sulfatreat technology is supplied by "MISwaco". Below is the link:

Iron Sponge process uses iron oxide impregnated wood chips which are laid out in a solid bed in a 2-vessel configuration where one vessel is under operation and other is under regeneration. Several grades of wood chips are available based on iron oxide content. They are commonly available as 6.5, 9, 15 and 20 lb iron oxide per bushel. Refer the link below for iron sponge supplier:

Hope this helps.
