How to determine the pressure difference inside a distillation tower
Thread Content
In this conventional distillation column, △P is sometimes large, sometimes small, and sometimes zero; it’s unclear when it is considered normal What do values that are too high or too low indicate? What is the purpose of measuring the pressure difference here? Also, what is the meaning of the pressure difference at the upper part of the distillation tower?
A positive pressure difference is the normal condition; there is definitely a pressure drop when passing through the tray packing. Large fluctuations in the pressure gauge may be related to fluid accumulation in the pressure guide tube. It may also be related to the flow inside the tower. The pressure measurement point also has an impact. The pressure difference in the distillation column can be used to determine the condition of the trays, such as whether they are clogged or damaged, etc
May I ask, if a tray falls off, will the pressure difference increase or decrease?
The size of the area that is ignored can be large or small
The pressure difference can reflect the actual operating conditions
To understand pressure, it is essential to know whether the filler inside the tower tank is blocked or has collapsed... What the plate above said is correct; if there are problems in the tower tank, the pressure may not necessarily be high or low – it depends on the nature of those problems
