Haldor Topsoe and Proton Ventures BV have successful started up the first TertiNOx™ catalyst reference at Kavala Fertilizers, one of the largest nitric acid producers in Greece.

Announcing the news yesterday (14th Jan), the companies said 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 SCR reactions to remove NOx.

Topsoe supplied both catalyst and basic engineering for the project.

“With the new deNOx and N₂O removal system, we are very proud to be able to outperform the current Best Available Technologies achieving extremely low emission levels,” says Dr. Theodora Kouloura, Chief Operating Officer at Kavala Fertilizers LTD.

“We are thrilled to see the excellent performance and positive carbon reduction of Topsoe’s TertiNOx™ technology in its first application world-wide,” added Janus Münster-Swendsen, Business Development Manager at Haldor Topsoe.

“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.”
