What causes a sudden rise in temperature at a certain point in the methanol synthesis tower?

What is the cause of a sudden increase in temperature at a certain point in the methanol synthesis tower? In a 200,000-ton methanol synthesis tower, the temperature at a certain point suddenly increased and remained high.
This phenomenon occurs when there is a leak in the synthesis tower
It depends on whether it is the import, export, or whether the temperatures at the same plane are all different.
Imbalance in the hydrogen-to-carbon ratio; increased CO content!
1. First, it is necessary to rule out any faults in the temperature measurement points. 2. The space velocity of the synthesis tower is too low. 3. Uneven catalyst loading or coking leads to uneven airflow distribution. 4. The heat exchange internals at this temperature measurement point are blocked or damaged, preventing the heat generated during restart from being removed in a timely manner, and so on.
First, it is necessary to clarify where the over-temperature point is located in the bed layer before making a judgment!
