Reasons for the low hydrogen sulfide level after the wet desulfurization tower but an increase in hydrogen sulfide level after the ammonium sulfate production section
Thread Content
Hello everyone: I would like to ask why hydrogen sulfide levels are low after the desulfurization tower, but become excessive in the ammonium sulfate production section. What could be the reason for this?
We encountered similar problems before, and no reasonable cause could be found at that time; however, once we kept the hydrogen sulfide level after desulfurization below 20 mg, such problems never occurred again
1. There is a problem with the location of the sampling point after the desulfurization tower. 2. The traffic valve has internal leakage.
