Fluctuations in temperature and pressure in the diesel hydrocracking fractionator?

Should it be set to manual mode for reflux, or should there be large fluctuations within a 30-degree range?

The specific process is as follows: more than 8 tons of reflux were used, yet the temperature still fluctuated significantly!

Now the settings have been adjusted, and the PID value has been changed. It seems that the tower pressure still needs to be stabilized; only by manually activating the reflux can the temperature remain stable

Stabilize the tower pressure and feed temperature.

The basis for operating a distillation tower is the presence of steam, and the prerequisite for stability is stable tower pressure
