Regarding the operation of distillation towers
Thread Content
Regarding plate towers, the higher the plate pressure drop, the better the operational stability or adaptability of the plates, as well as the greater the operational flexibility. How should this statement be understood? I hope experts can provide some guidance.
Who said this? Don’t try to understand what Hu says nonsense.
Isn’t it true that the tower pressure drop shouldn’t be the higher the better? There is a reasonable range. If it is too high, it indicates flooding or other abnormalities, resulting in a decrease in tower efficiency!

This applies only to liquid leakage from the trays; the greater the plate pressure drop, the larger its proportion in the total pressure drop as the fluid passes through the trays. This results in less influence from external factors on the liquid layer distribution on the trays, which in turn facilitates a more uniform distribution of the liquid.
I don’t know who said this, but if the pressure drop across the trays is greatest when the liquid level in your tower rises to fill the entire tower, then what’s there left to talk about stability and resilience? !
Appropriately increasing the operating pressure and pressure drop of the tower can help address the problem of flooding
