An increase in the spray density for wet flue gas desulfurization also leads to an increase in particulate matter detected online

Our company has two wet flue gas desulfurization systems for coke oven gas: one uses the double-alkali method for desulfurizing coke oven flue gas, while the other employs ammonia water for desulfurization in coke oven gas power plants. Both systems are experiencing the same problem – when the flue gas flow rate remains constant, increasing the spraying density leads to an increase in particulate matter levels in both systems. Third-party maintenance personnel using infrared and ultraviolet particle detection equipment say that water vapor is mistaken for particulate matter. Is there any way to reduce these particulate levels?
We use the magnesium oxide method for desulfurization, and we face this same issue. At present, the problem of low production capacity is not significant; however, it remains a matter of concern. We would appreciate it if experts could share their insights!
There is a problem with the design; the flow rate is too high. Please provide the tower diameter and the actual flue gas flow rate
I encountered the same problem while debugging as well
Will it detect water vapor as particulate matter? Is it still because of the high gas velocity that more is carried away?
There’s no good solution to this; it’s a drawback of wet flue gas desulfurization. You can ask plants that use sintering processes about it, as they make use of wet desulfurization methods on a large scale
If you need flow meters or dust monitors for detecting particulates in air and water, please send me a private message
Why isn’t there anyone knowledgeable who responds to this topic? We have the same problem here as well·~·Especially during times of heavy rain and sudden temperature drops, the increase in particles is particularly noticeable
