What to do if the temperature of the distillation column trays is too high and the production volume is insufficient?

The temperature is high, and the yield remains insufficient. Why is that? Could any expert help me? Thank you to all the experts~
Consider the temperature inside the kettle and the reflux flow to reduce the tray temperature.
1. Increase the reflux flow rate to reduce the temperature returning to the tower. 2. The thermal balance inside the tower is disrupted, and a new thermal balance is established. 3. Or perhaps the tower is simply too large and the feed load is too low, resulting in uneven vapor-liquid contact.
The information provided by the poster isn’t detailed enough. Has there been an analysis of the composition at the top and bottom of the tower, with a material balance conducted? It’s possible that the composition of the feed has changed (assuming that the operating pressure of the tower remains unchanged).
Try increasing the reflux ratio first; if that doesn’t work, then a detailed analysis will be necessary. Data such as the process parameters that need to be adjusted and the material composition are required.
Hehe, just follow the parameters specified in the operating procedure step by step. If capacity is exceeded by adding equipment, it constitutes a safety risk. If the equipment does not meet the standards, it is necessary to clarify the relevant factors; the more detailed, the better it will be for resolving the issue.
The temperature of the kettle is too high; reduce it appropriately to decrease the amount of vapor
Is the feed too rich in heavy components? Ensure strict control over raw materials.
Your question is too general – high temperature, what about pressure? What about the feed composition? Is there any change in production? What kind of production? At the top of the tower or at the bottom? The materials are always in balance; if there’s less at the bottom of the tower, then there will naturally be more at the top. . .
