Nitrogen Oxides are a family of poisonous, highly reactive gases that are formed when fuel is burned at high temperatures. NOx pollution are emitted by vehicles and various non-road vehicles including construction equipment, marine vessels and industrial sources such as power plants, industrial boilers, and cement kilns. It is a strong oxidizing agent and plays a major role in the atmospheric reactions with volatile organic compounds (VOC) that produce ozone (smog) associated with human health and environmental risks. They contribute to the damage of trees at high elevations and in some regions lakes and streams may become so acidic that they cannot support aquatic life. In addition, acid deposition accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our collective cultural heritage. We all will benefit from reduced air emissions with an improved ecosystem and human health.

Ionada’s iDeNOx™ Selective Catalytic Reduction (SCR) technology removes up to 97% of all nitrogen oxides from exhaust gases. iDeNOx™ is a means of converting nitrogen oxides (NOx) with the aid of a catalyst into diatomic nitrogen (N2), and water (H2O). The reductant urea (CO(NH2)2) is injected into the exhaust flue gas and is reacted onto a catalyst. As the reaction drives toward completion nitrogen (N2) and carbon dioxide (CO2) are produced.

iDeNOx™ provides a viable, sustainable and environmental solution to reduce harmful emissions. Ionada’s iDeNOx™ maximize performance while meeting EPA Tier 4 and IMO Tier III emission regulations. iDeNOx™ technology can improve on engine packages, while allowing systems to remain compact and easy to service, helping improve overall fuel economy.

  • removes up to 97% of nitrogen oxides from exhaust
  • removes up to 95% of VOCs, CO
  • ammonia slip less than 5 ppm
  • compact solution
  • long life catalyst
  • sulfur resistant oxidation catalyst
  • low pressure drop

The urea reductant converts poisonous environmentally harmful nitrogen oxides into harmless environmentally safe nitrogen and water vapor.

(NH2)2CO → NH3 + HNCO

HNCO + H2O → CO2 + NH3

(NH2)2CO + H2O → 2 NH3 + CO2

2 (NH2)2CO + 4 NO + O2 → 4 N2 + 4 H2O + 2 CO2 and
4 (NH2)2CO + 6 NO2 → 7 N2 + 8 H2O + 4 CO2
