Possible reasons for the increase in pressure in the distillation tower include: 1. Insufficient cooling in the top condenser； 2. Excessive flow rate of the pump at the bottom of the tower ； 3. Excessively high feed temperature or excessive amount of feed ； 4. Scaling or blockage inside the tower. .
The information presented is good; two additional points: an excessive feed load, or a change in the composition of the feed, can also lead to an increased load within the tower. Overloading of certain trays within the tower can likewise result in an increase in tower pressure； Furthermore, coking and blockage of the tower internals, or freezing and blockage in low-temperature towers, can also lead to an increase in tower pressure ；
Increase in column pressure: 1. Increased steam consumption; 2. Condenser design; 3. High liquid level in the column; 4. Failure to remove the product in a timely manner, resulting in an imbalance in materials; 5. A simple increase in column pressure may be caused by the detachment of tray plates (or blockage in packed columns)
