Why is the temperature of the low tower fluctuating so much?
Thread Content
The pressure in the low tower is very stable, but the temperature of the bottom and top of the low tower fluctuates by around 0.8. Remote temperature sensors are also good for detection. Could anyone tell me what’s going on?
OP, you mentioned that either the temperatures at the bottom and top of the tower fluctuate, or the temperature difference in the distillation section of the tower varies – the causes of these two problems are different. A few months ago, the temperature at the bottom of our high-boiling-point tower fluctuated greatly; after inspection by the instrument technicians, it was found that all the instruments were working properly, and subsequent checks by the technical staff also showed that the process was normal. In the end, they couldn’t identify the cause. Actually, the problem was quite simple: hitting the thermocouple with a small iron rod resolved the issue.
The low-pressure reactor vessel and the pressure at the top of the vessel are both normal; it’s just that the temperature at the top is quite high~~ What could be the reason for this? Experts, please give me some advice~~!
