The BYNOX SYSTEM reduces NOx emissions by injecting a urea solution directly into the flow of exhaust gases.
A specifically designed mixer nebulises the urea solution. Subsequent reactions within the SCR catalyst, which occur at a temperature of between 300 and 500 °C, enable the following chemical activities:
N2H4CO + H2O = 2NH3 + CO2 (Decomposition of the urea)
4NO + O2 + 4NH3 = 4N2 + 6H2O
6NO2 + 8NH3 = 7N2 + 12H2O
NO + NO2 + 2NH3 = 2N2 + 3H2O
The basic components of the BYNOX SYSTEM required for the afore-mentioned reactions are the batching module and the SCR catalyst.
