SafeDeNOx Urea to Ammonia
Chemithon’s patented SafeDeNOx process economically generates ammonia from urea for Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) of Nitrous Oxides (NOx). Our unique process uses a catalyst to accelerate the reaction so the system responds quickly to changes in ammonia demand. Click Here for More Info

The Safe DeNOx Process offers: Faster Reaction Time Smaller Equipment Skid Energy-Efficient Process Minimal Urea Handling Greater Plant Safety Constant Ammonia Concentrations

Ammonia Systems
Chemithon supplies anhydrous, aqueous or urea based systems for selective non-catalytic reduction (SNCR) for NOx reduction. In the SNCR process dilute ammonia gas is injected into the flue gas exiting the boiler where it thermally oxidizes the NOx in the flue gas stream to form Nitrogen (N2) and water vapor.Click Here for More Info

Flue Gas Conditioning Systems
Chemithon Corporation has supplied several hundred Sulfur Trioxide Flue Gas Conditioning systems worldwide. Sulfur Trioxide gas is injected in the boiler exhaust gas stream to reduce fly ash resistivity, improving Electrostatic Precipitator performance. Dual FGC is offered with ammonia injection along with SO3 injection. Unlike sulfur trioxide flue gas conditioning which only reduces ash resistivity, ammonia conditioning is used for a variety of reasons:    Click Here for More Info

• Improve fly ash absorption of sulfur trioxide for low alkali ash.
• Agglomerate fly ash and reduce rapper re-entrainment
• Increase space charge effect to optimize collection efficiency
• Improve high carbon fly ash collection
• Lower acid dew point when high sulfur coal is burned, minimizing precipitator corrosion
• Reduce SO3 and slip and resulting SO3 plume
• Dual conditioning is simply independent injection of both sulfur dioxide.and ammonia to achieve the benefits of both.
