Contributing to climate and
ENVIRONMENTAL PROTECTION IN THREE WAYSBy mitigating the greenhouse effect, helping to preserve the ozone layer, and reducing atmospheric pollution with other, health and climate damaging nitrogen oxides, the EnviCat® NOx process contributes to climate and environmental protection. The catalyst EnviCat®N2O is a central component of the innovative process.
An innovative catalyst in an ingenious process
The Clariant catalyst EnviCat® N2O used in the EnviCat® NOx process, developed by ThyssenKrupp Uhde GmbH, removes nearly all of the nitrous oxide from the tail gas of nitric acid plants and converts it in two stages to the harmless substances oxygen, nitrogen and water. At the heart of the process is the highly active catalyst EnviCat® N2O consisting of porous, crystalline zeolites.
Meeting legal restrictions without impacting the manufacturing process
for the strict limits on nitrous oxide gas emissions
12 MILLION TONS CO2
Every year, the EnviCat® NOx process purifies nitrous oxide emissions equivalent to greenhouse gas emissions of four million cars per year
