The DeNOx Selective Catalytic Reduction Process
The deNOx SCR process converts NOx emissions into diatomic nitrogen (N2) and water (H2O) vapor. That is accomplished by injecting ammonia (NH3) or urea into the flue gas stream and then passing it through a catalyst bed.
Fundamental process reactions:
4NO + 4NH3 + O2 ⇒ 4N2 + 6H2O
6NO2 + 8NH3 ⇒ 7N2 + 12H2O
This simplified illustration depicts the basic design, flow pattern, and equipment used in a typical McGill deNOx reactor.
The Design Process and Considerations
Our sales and design engineers will review your process conditions to provide you with the best deNOx control system solution, which includes design analysis of the following:
DeNOx removal efficiency
Flue gas chemistry
Operating temperature
Catalyst selection
Ammonia injection location
CFD modeling and equipment layout
Computational fluid dynamics (CFD) modeling, as shown in this diagram, is a key element in the design of each McGill deNOx reactor.
