Midas® Odor Control Media

Combines select active ingredients and premium quality bituminous coal to produce an odor control media unmatched in today’s market for the removal of H2S, HCl, SO2 and other volatile organic compounds (VOC).
Midas® Odor Control Media (OCM) is unlike any other odor control media that is available in the marketplace today. A special manufacturing process which combines selected active ingredients and premium quality bituminous coal gives Midas OCM an extraordinarily high H2S breakthrough capacity. This odor control media is not impregnated and therefore does not suffer the serious drawbacks associated with alkali-impregnated carbons. Midas OCM has an ignition temperature that is similar to virgin coal-based carbons (>450°C) and since it is not impregnated with a strong alkali, is much safer to load, start-up and remove from an adsorber system.

Midas OCM is a high surface area macroporous media with a large pore volume. The lack of an impregnant means all of the media's pore volume and surface area are available for storing the sulfur produced during the catalytic oxidation of H2S and for the adsorption of any volatile organic compounds (VOCs) that may be present in the gas stream. The high H2S and acidic gas loading capacity of Midas OCM is not affected by the presence of high CO2 levels. The 4mm pellet diameter offers a low pressure drop to gas flows and a superior hardness offers excellent resistance to dust and fines formation.



Midas OCM can be successfully used in any application where impregnated or other odor control carbons are currently used including:

  • Sewage treatment plants
  • Refineries and pulp and paper mills
  • Odor Control
  • Removal of acidic gases such as HCl and SO2
  • VOC removal​

 Features and Benefits

  • Exceptionally high H2S loading capacity
