Nitrous oxide abatement – air emissions monitoring

Trinity assisted Incitec Pivot with air emission monitoring for NO, NO2, methane and N2O, using our portable FTIR (fourier transform infrared spectroscopy) and other portable real-time gas analysers.

How we helped

Trinity assisted Incitec Pivot with air emission monitoring for NO, NO2, methane and N2O, using our portable FTIR (fourier transform infrared spectroscopy) and other portable real-time gas analysers.

We were able to provide real time readings on site during Incitec Pivot’s commissioning of a significant nitrous oxide abatement project.

Our air monitoring team spent three days at the site conducting emission testing during commissioning. The testing was able to help Incitec Pivot confirm that the N2O emissions had been reduced by approximately 99% and the NOx emissions by 95%, with the implementation of the new abatement system.

The collaboration between Trinity’s air monitoring team and our clients exemplifies our critical role in environmental monitoring to support sustainable industrial practices. The successful verification of the effectiveness of Incitec Pivot’s abatement project underscores the importance of ongoing monitoring and verification processes in mitigating air pollution and moving towards a more sustainable future.

About the project

Nitrous oxide has 265 times the global warming potential of carbon dioxide. As part of their decarbonisation efforts, Incitec Pivot has invested in a $20 million nitrous oxide abatement project at their Dyno Nobel Moranbah Plant. The project aims to reduce emissions at the equivalence of 220,000 tonnes of carbon dioxide per year.

The project involves converting nitrous oxide emissions into nitrogen, water vapour and carbon dioxide, greatly minimising nitrous oxide emissions from the process of manufacturing explosive products for the mining industry. For more information, see the Incitec Pivot website.

Trinity are routinely engaged to undertake independent stack testing at Dyno Nobel Moranbah, as required by the Environmental Authority issued by the Queensland Department of Environment & Science.

Trinity were engaged to provide analysis of the pollutants and reactants upstream of the Tertiary N2O Abatement Reactor during its commissioning. The analysis gave insight into how the new abatement system was performing, which assisted in its optimisation and confirmed that our own new online analysers were working satisfactorily.

The Trinity data was particularly useful with troubleshooting when the initial plant performance after start-up was not as expected.
