If the reboiling heat source at the bottom of the distillation tower is suddenly cut off, what type of alarm should be used to enable rapid response to this situation?

What if the situation is exactly the opposite, with an excessive heat source flow?
Generally, it can be determined using flow deviation and valve opening degree; a clamp in automatic mode can also be used to prevent such problems. Actually, it’s the same whether it’s turned up or turned down.
Alarm for heat source flow rate indication; the most direct option: victory:
Install a flow meter with upper and lower limit alarms. If you want to save money, install an inlet and outlet pressure difference gauge to use for pressure difference alarms. If it can be cheaper, install two pressure gauges and connect them to a single display gauge. If it’s any cheaper, install two on-site pressure gauges. If it’s even cheaper, then there’s no need to install anything; just monitor the temperature of the tower bottom.
If steam heating is used, it is best to employ steam pressure as a control mechanism; a PICA interlock alarm can also be added
This should be simple, right? Just use the pressure interlock alarm from the reboiler’s heat source
I didn’t know before; after seeing this, I realize there are quite good profits
I’ve learned a lot; it seems that there are various ways to solve the same problems, depending on whether you have money or not.
