Analysis of the reasons for high steam consumption in distillation towers

Reasons for high steam consumption at the bottom of the distillation tower
Has the reflux been turned on? Is the heat exchange efficiency of the reboiler poor?
Is a steam trap good?； Has the feed temperature decreased? ； The backflow increases ； The feed size has increased ； Poor insulation of the tower/reboiler ； The pressure has increased ； Tray failure.
The heat exchange efficiency is poor, there is leakage, and the flow rate display is inaccurate!
The original poster’s description isn’t very clear – has the consumption increased, or has it always been this high?
