SCR NOx removal process requires ammonia, either anhydrous or aqueous, which is a toxic substance. The hazards from exposure vary from minor discomfort to toxic poisoning and asphyxiation.

To counter this risk and ensure the safety of plant personnel and the surrounding community, Hamon Environmental offers a patented on site Urea-to-Ammonia generation system, U2A™, that produces ammonia by a method that avoids the hazards of its transportation, transfer, and storage.

In addition, there are economic benefits versus using unregulated lower concentrations of aqueous ammonia.
