Emission monitoring for nitric acid plants
Thread Content
In the newly built nitric acid plants, is it necessary to install online exhaust gas monitors in order to achieve online monitoring of NOx in the nitric acid exhaust gases?
There are no mandatory regulations in this area at present, but policies are likely to be introduced soon. It has to be installed sooner or later.
There is no need to install an exhaust gas monitor at all at present
Our company conducts sampling and analysis once a week; in case of special circumstances, the analysis is done once a day
Online monitors for boiler exhaust gases can detect substances such as SO2 and NOx; however, it is not clear whether they are suitable for use with nitric acid exhaust gases, as there is no SO2 in such exhaust gases.
It is needed now, and the analyzer data must be fed to the **environmental protection department**
