- Pollution Reactions
- NOx
- NO2 --(UVA)-> NO + O
- O + O2 --> O3
- NO + O3 + HC --(sunlight)-> PANs
- NOx
- NO2 --(UVA)-> NO + O
- O + O2 --> O3
- NO + O3 + HC --(sunlight)-> PANs
- NO + O3 + HC --(sunlight)-> PANs
- O + O2 --> O3
- 2CO(NH2)2 + 4NO + O2 --> 4N2 + 2CO2 + 4 H2O
- Urea Spray
- NO2 --(UVA)-> NO + O
- NOx
- NO + O3 + HC --(sunlight)-> PANs
- O + O2 --> O3
- 2CO(NH2)2 + 4NO + O2 --> 4N2 + 2CO2 + 4 H2O
- Urea Spray
- NO2 --(UVA)-> NO + O
- SOx
- Flue Gas Desulphurisation
- 2CaCO3 + 2SO2 + O2 --> 2CaSO4 + 2CO2
- 2CaSO4 is Gysum, used in making plaster

- 2CaCO3 + 2SO2 + O2 --> 2CaSO4 + 2CO2
- Sodium Sulphite Scrubbing
- Na2SO3 +H2O + SO2 2NaHSO3
- SO2 + H2O H2SO3
- (Acid Rain)
