EnviCat™ N2O
The EnviCat N2O catalyst removes nitrous oxide (N2O) from the tail gas of nitric acid plants. Nitrous oxide – commonly known as happy gas or laughing gas – is extremely harmful for our climate because of its about 25 times greater longevity in the earth's atmosphere than CO2.
The catalyst removes nearly all of the nitrous oxide from the tail gas of nitric acid plants. It also renders innocuous other nitrogen oxides (often called NOx) that represent a considerable pollution threat. The nitrous oxide is converted in two stages: in the first stage, the nitrous oxide is decomposed to oxygen and nitrogen with the aid of the catalyst EnviCat N2O. In the second stage, the nitrogen oxides are mixed with ammonia to produce harmless nitrogen and water.
