How to reduce nitrogen oxides in wet sulfuric acid process exhaust gases
Thread Content
In our factory, the sulfuric acid production process follows the wet method. With increasingly strict environmental regulations, it is necessary to find ways to reduce nitrogen oxides in the exhaust gases. Those who have solutions can share their ideas with us.

Adding a denitration device before conversion – it’s very small
It means adding a set of denitration reactors and ammonia injection equipment before the conversion process
How to address the issues of corrosion and the sensitivity of denitration catalysts to sulfur
The operating temperature for SCR denitration using the wet acid production method is around 400°C, and there is no issue of ABS clogging. As for selectivity, it is even less of an issue; a low selectivity is beneficial for the SO2 conversion rate.
