Haldor Topsøe, Lyngby, Denmark, and Dutch firm Proton Ventures BV have announced the start-up of the first TertiNOx™ catalyst reference to reduce nitrous oxide (N2O) and nitrogen oxides NOx at Greece’s Kavala Fertilizers Ltd.
The TertiNOx catalyst removes N2O, a potent greenhouse gas with an estimated effect on global warming 298 times that of carbon dioxide (CO2), Topsøe, said.
“At the current performance level, Kavala Fertilizers’ nitric acid unit will reduce its greenhouse gas emissions by more than 30.000 mt CO2 equivalents per year,” said the Danish catalysis company, adding that Kavala Fertilizers is one of the largest nitric acid producers in Greece.
Topsøe supplied both catalyst and basic engineering for the project.
According to the Danish company, Kavala’s nitric acid plant has already exceeded its design conversion with N2O emissions below 10 ppm, low ammonia slip, and practically eliminated NOx emissions.
