Sulfuric acid plant exhaust gas testing
Thread Content
I’m asking my fellow students: why is it difficult to detect the exhaust gases emitted by my factory after it was equipped with an exhaust gas absorption system?
It’s not that your exhaust emissions can’t be detected; it’s that all the sulfur dioxide has been absorbed, and there’s none left. We encountered the same situation before
If all the sulfur dioxide is absorbed, then will there still be smoke when it is vented?
3# taigefor That is the volatilization of ammonium sulfate
So how can ammonia sulfate be removed? Does it have an impact on the testing?
5# taigefor: In fact, there is no sulfur dioxide in your exhaust gases anymore – it has all been absorbed, which indicates that your absorption system is effective. Therefore, the presence of ammonium sulfate has no impact on your analysis results; it only causes white mist to appear

It is produced as a result of a reaction with ammonia; it is a nitrogen fertilizer. We did not remove it but released it directly. If you want to remove it, it’s simple – just add an absorption tower to absorb it using water, and it can also be used as fertilizer for sale
