What are the causes of the phenomenon that occurs after liquid overflows in the distillation tower, and what are the corrective measures?

Significant fluctuations in the amount of steam added; 3. Excessively high inlet liquid temperature; 4. Low temperature at the top; 5. Excessively high liquid level at the bottom of the second distillation column, resulting in high load. Outcome: The processed product does not meet quality standards. Measures: Adjust the load gradually, avoiding sudden increases or decreases. The opening degree of the steam heating valves at the bottom should also be adjusted smoothly. Pay attention to maintaining balance and proper pressure throughout the steam system. Keep the temperature entering the tower between 110–120°C
Phenomenon: The temperature difference between the upper part of the decompression tower and the outlet gas decreases, the temperature in the subsequent system rises, and the pressure drops. Treatment: Reduce load and steam output significantly; gradually increase them back only after conditions stabilize.
