Haldor Topsoe and Proton Ventures BV announce TertiNOx™ startup

Haldor Topsoe and Proton Ventures BV have announced the successful startup of the first TertiNOx™ catalyst reference at Kavala Fertilizers, a nitric acid producer in Greece. Haldor Topsoe has supplied both catalyst and basic engineering for the project. The plant has already exceeded its design conversion with N2O emissions below 10 ppm, low ammonia slip, and practically eliminated NOx emissions.

TertiNOx is a catalyst for removal of nitrous oxide, also known as laughing gas. The catalyst is developed for the nitric acid industry where N2O is formed as byproduct of the oxidation of ammonia. TertiNOx is also active for selective catalytic reduction (SCR) reactions to remove NOx. 

N2O is a very potent greenhouse gas, and even relatively small concentrations have a big negative impact on the climate. Apart from the environmental benefits, reducing N2O emissions from nitric acid units is a cost-effective way to reduce greenhouse gas (GHG) emissions and save on CO2 credits.

“We are thrilled to see the excellent performance and positive carbon reduction of Topsoe’s TertiNOx technology in its first application world-wide. Globally, it is very important to reduce emissions of the extremely potent greenhouse gas, N2O, as well as NOx. This project has shown that TertiNOx does that in a very cost-effective and efficient way. We are extremely proud to fight climate change together with Proton Ventures and Kavala Fertilizers,” said Janus Münster-Swendsen, Business Development Manager at Haldor Topsoe.
