Why are packed towers most commonly used in pressure reduction towers?
Thread Content
Thank you all, guys and girls; please give me more suggestions
The purpose of a vacuum distillation column is to increase the relative volatility by reducing pressure; therefore, pressure is a key factor. Generally speaking, the pressure drop across a packed column is lower than that in a tray column, which leads to this conclusion.
I think this issue should be viewed from the perspective of mass transfer between the gas and liquid phases inside the tower; it is possible that in a packed tower, lower pressures facilitate mass transfer between these two phases.
Thank you for your answer. It is probably because the pressure drop in the packed tower is relatively low, and the packing facilitates mass and heat transfer.
The main reason is that the pressure drop in packed towers is relatively low; originally, the operating pressure in vacuum towers is not high anyway
Not quite sure? ? “What is “pressure drop”? I just started studying this subject and there are many things I don’t understand; please help me a lot! !
The total pressure drop in a packed tower is lower than that in a plate tower; there is no conceptual difference between resistance loss and pressure drop in this context.
The pressure drop in a packed tower is much lower than that in a plate tower, and this is the main reason
