Everyone who’s an expert, come and take a look at why there’s such a large temperature difference in the steam regenerator (←←)

What’s causing the large temperature difference between the low temperature in the isobutane distillation column and the reverse column temperature?
It seems there is some, but in reality there’s almost none left that affects the reboiler. When the temperature difference in the reboiler is high, check if there’s anything at the top of the tower. If there’s nothing, it means the liquid level is gone.
If the liquid level at the bottom of the tower is normal but the temperature difference in the reboiler is large, limited reboiler flow should be considered. In a typical distillation column, the reboiler load is controlled by the temperature of the sensitive plate in the column; in other words, the amount of heat applied remains constant. If the temperature of the liquid returning to the column is high, it indicates that the circulation rate is low. The possible reasons for this include blockages caused by impurities, valves that are not fully open, or an incomplete establishment of thermal siphoning during startup.
No images, just questions. I don’t know how to reply = =?
