To comply with environmental legislations, all new and most existing nitric acid plants must implement measures to reduce N2 O emissions to the atmosphere. This article explores the opportunities presented by Stamicarbon’s tertiary abatement technology for both existing and grassroots nitric acid plants to enhance sustainability and efficiency and discover the advantages of incorporating these technologies into a green fertilizer complex.

NextChem Tech, has signed a contract with Paul Wurth SA, a subsidiary of SMS group, and Norsk e-Fuel AS for a licensing and engineering design package relating to its NX CPO (catalytic partial oxidation) technology, which will be used in an industrial scale plant producing sustainable aviation fuel (SAF) from green hydrogen and biogenic CO2 in Mosjøen, Norway. NextChem’s NX CPO technology produces synthesis gas via a very fast controlled partial oxidation reaction. When applied to synthetic fuel production, it can improve carbon efficiency recovery yield. The first plant developed by Norsk e-Fuel will have a production capacity of 40,000 t/a of green fuel and will enter operation after 2026. Based on the initial design, two additional facilities with a capacity of around 80 000 t/a each are planned to be built by 2030. The fuels will current aviation emissions.

The US is experiencing a new boom in nitrogen projects, with a number of carbon capture ammonia plants under development.

Catalyst development for nitric acid plants is strongly dependent on operating pressures and nitrogen loading levels. Dr Hadi Nozari of Johnson Matthey provides a review of some key catalyst design principles, emphasising the critical role of operating pressure in catalyst selection and highlighting the innovative contributions of Johnson Matthey in advancing catalyst technology for ultra-high-pressure ammonia oxidation in nitric acid plants.
