Ammonia desulfurization
Thread Content
On site, I observed that during the operation of the desulfurization system, the volume of the circulating liquid was increasing; now, 20 cubic meters of this liquid must be discharged daily. I have checked for any leaks in the equipment, and all such issues have been resolved. It has been checked whether mist entrainment is occurring in the pre-cooling tower; it is possible that the ammonia vapor from ammonia evaporation is responsible for this issue. However, this phenomenon does not show such a significant increase during summer operations. Previously, it was thought that when the amount of by-products resulting from desulfurization reached a certain level, fixed emissions would occur along with the addition of fresh water. But now there is a continuous increase in these emissions, which forces us to reconsider our emission strategies. I would appreciate it if experts could suggest other possible causes for this issue
We’re the same; we haven’t found the reason
We have encountered this problem before; it was due to excessive water content in the concentrated ammonia solution
I know the reasons you mentioned. You can contact me on QQ at 734534624; maybe I can help solve the problem and improve your ammonia utilization rate.
The main factor is the formation of combined water during the gas desulfurization process. During gas desulfurization in summer, the temperature rises significantly, which allows a considerable amount of water vapor to be removed
