Formulation of dry scrubber with 80% H2S absorption capacity

  • Eduard from Bioconservacion
  • From Spain
  • Responsive
  • Knowhow and Research output

Summary of the technology

The formulation has been repeatedly tested in a laboratory, yielding an absorption capacity of > 80 g H2S/100 g product (using ASTM D6646). I am looking to find a company in the gas/air phase treatment industry that is keen on taking this product to the market. Given its superior absorption capacity, the operational costs are significantly lower than its competitors. Please contact me to further discuss.


H2S Dry Scrubber – Odor Control

Technical Description of the Product

  • The absorbent combines premium quality activated carbon together with a blend of catalytically active inorganic phases
  • Mechanism: H2S is catalytically oxidized to sulfur (S) in the active sites on metal oxides. Next, sulfur migrates and builds up in the micropores of the activated carbon phase. Thus, the metal oxides are available again to oxidize new H2S molecules
  • H2S is not converted to sulfuric acid which may lead to equipment corrosion problems

Added Benefits

  • High H2S removal efficiency (> 99%) upon variable inlet conditions
  • Sulfur loading is not affected in the presence of high CO2 levels
  • Does not require frequent change outs or time consuming regenerating processes
  • Safe to handle and use
  • The high ignition temperature (420 ºC) minimizes the risk of bed fire
  • Low pressure drop, due to the nominal pellet diameter (4 mm)
  • Does not need to undergo long term conditioning prior to being put into operation


Any use that requires control of H2S gas, such as:

  • Wastewater treatment plants
  • Pumping stations
  • Wet wells
  • Lift stations
  • Sludge holding tanks
  • Refineries
  • Pulp and paper mills
  • Composting
