NOx Reduction in Selective Catalytic Reduction (SCR)

The NOx reduction performance of an SCR catalyst is influenced by the gas temperature, gas flow rate and AdBlue^® dosing unit. Intelligent imaging systems quantify the AdBlue^® spray characteristics, such as spray entrainment, evaporation, wall impingement and droplet size. Measurement of the gas flow field, gas temperature and catalyst surface temperature improve the optimization and understanding of the complex processes inside the denox catalyst system.
