Ammonia nitrogen issue in flue gas discharged from flue gas desulfurization
Thread Content
The issue of ammonia nitrogen in the flue gas discharged after flue gas desulfurization: Is the nitrogen oxide content in the flue gas related to the pH value of the slurry at the bottom of the tower? Recently, our company experienced high levels of nitrogen oxides in its flue gas; by increasing the pH value of the slurry, the nitrogen oxide level decreased. Was this a coincidence, or was some chemical reaction taking place?
We do the same when making adjustments; when the sulfur content increases, the nitrogen oxides also decrease
Could some expert explain the process behind the catalytic reduction of nitrogen oxides in flue gases? How to handle it
It mainly comes from the catalytic device at the front, and a portion of it is generated through combustion; we have conducted a detailed analysis of this
Although it has dropped, do not mention the pH casually, as it will have a significant impact on the desulfurization system later on
I would like to ask. If the olefins are high, are the emitted nitrogen oxides also high?
