A great deal of effort has been devoted to developing catalysts for deNOx processes with a focus on NO reduction from exhaust gases. The ammonia-assisted selective catalytic reduction (NH3-SCR) over Cuexchanged zeolites is by far the most effective method to reduce NOx to N2 and H2O. However, this process has several inherent limitations, notably ...
How it works In the combustion process nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). ...
In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous ...

This method is performed in so-called DeNOx systems and has a wide range of applications: Thermal power plants fired by coal, oil, or gas Refineries Biofuel plants Waste-to-energy plants The location of the DeNOx system within the flue gas cleaning process depends on the type of fuel involved. In a tail-end configuration, the ...
