Odour and H2S removal in the case of chemical barge degassing

H2S removal AIRCON H

When contaminants such as H2S and other odours need to be removed from an air or gas stream, it is important to select the correct activated carbon filter. The selection depends on several factors like:

  • Flow rate;
  • Concentration;
  • Type of impurity;
  • Superficial contact time;
  • Location.

The type of filter will also influence the other auxiliary equipment needed for the removal of the impurities. DESOTEC acactivated carbon has a wide experience in selecting the most cost-effective activated carbon solution and is always ready to help find an appropriate solution. Our experienced engineers can help you to select the best impregnated AIRPEL® extruded activated carbons with enhanced adsorption capacity for H2S.

At DESOTEC’s facilities, all used carbon is analysed so the right measures can be taken for handling and removing the saturated carbon out of the mobile filters. All molecules that were adsorbed on the activated carbon at the customers’ site, are desorbed inside DESOTEC’s reactivation furnaces. These contaminants are then fully destroyed, in accordance with National and European legislationby an incineration and neutralisation setup. The entire installation and it's emissions are under continuous on-line monitoring, which guarantees that only harmless water vapour is seen exiting the chimney.
