Project related text:
Neochim PLC operates a nitric acid production plant. Nitric acid is produced through the oxidation of ammonia (NH3) on precious metal catalyst gauze in the ammonia burner of a nitric acid plant. With the use of proper catalyst, 98% at most (92 -96% typical) of the introduced ammonia are transformed in nitric oxide (NO). The remaining part reacts in an undesirable chemical reactions that lead to formation of nitrous oxide (N2O), along with other compounds.
The idea of the project is to install selective De N2O catalysts right below the platinum gauze in the catalytic reactor and that catalyst is to be called secondary catalyst. The level of N2O in the gas mix, formed as a result of primary ammonia oxidation reaction, will be reduced with the help of that secondary catalyst.
Current status of the project Operational
Total verified emission reductions 105593.0 t CO2 equivalent
