Desulfurization tower level issue
Thread Content
The liquid level in the desulfurization tower is required to be maintained at 5.5 meters. Sometimes, the liquid level in this tower keeps dropping, reaching 5.0 meters. What causes this?
It suddenly started bubbling; I can only guess.
It should be caused by an increase in system resistance and an increase in gas pressure
One issue is system pressure; another is whether there is any suspension in your tower, as well as whether there is a liquid-overflow tank. The absence of such a tank means that fluctuations in the regeneration pressure can also affect the liquid level in the desulfurization tower
It’s important to know what structure the desulfurization tower has and what kind of desulfurization process is used.
No leaks were found. If there is a leak, which valve are you referring to as having a leak? The inlet valve of the circulation pump? Even in the case of internal leakage, it is still far below the pump’s flow rate.
What does sudden foaming mean? I’ve just started learning about desulfurization and don’t understand it very well. Viewed from the top of the regeneration tower, what overflows includes not only sulfur foam but also some desulfurization liquid. Why is this? Where should it be controlled from?
I’m not an expert in this field; it requires your daily operational experience to make a comprehensive judgment
