Why could the liquid level at the bottom of the distillation tower suddenly rise from 30 to over 100 and then drop back to around 30?

It might be a problem with the level gauge, causing inaccurate readings; it’s possible to go to the site to check the situation and compare the levels there with those in the control room
What is a bottom-heating device? Has it not changed at all?
If it’s only temporary, it should not be caused by changes in the feed or reflux flow rate.
Is it calibration of the on-site measurement device? There is a lack of communication between the instrument operators and the operators.
1. Problems with the instrument itself 2. Problems with the installation location of the instrument
It’s probably a problem with the plug-in in the instrument remote transmission room; I encounter this situation often. The process takes only 3 seconds...
The measuring device needs to be checked, and the data recording system should also be examined. Also, make sure not to fill the tower completely with liquid – do you remember that? In 2005, BP’s plant in Texas filled its tower with liquid, which then spilled out from the top of the tower (apparently because the pressure safety valve was overridden), covering the ground with liquid. . . Result: Explosion: @; the factory was destroyed. BP ordered all factories to conduct thorough safety inspections within 1 month. Be careful and resolve this issue
Comrade on the 7th floor: Please explain how to solve this and how to avoid it
1. It is recommended to check the accuracy of the level gauge. 2. It is suggested to consider checking whether the downcomer is blocked; obviously, this cannot be determined without shutting down the system, and it depends on how clean the tower is. 3. Check whether there are any leaks in the reboiler at the bottom of the tower
I think the first thing to ask is: after the above phenomenon occurred, was the liquid level gauge at the site checked? Then make plans for the next step! ! :lol
