Reasons: 1. High liquid level at the bottom of the tower, resulting in poor separation; 2. Low steam pressure and low temperature; 3. Excessive feed volume with high acidity; 4. Leakage inside the heat exchanger; 5. Low amount of material extracted from the side stream. Solutions: 1. Increase the amount of acidic gas extracted while maintaining the top temperature of the tower; 2. Raise the temperature at the bottom of the tower; 3. Stabilize the feed volume; 4. Repair the heat exchanger through a bypass; 5. Increase the amount of material extracted from the side stream

Reason: The liquid level at the bottom of Tower 1 is high, causing flooding of the tower and resulting in poor separation efficiency. 2 Low steam pressure 3 High feed rate and high concentration of acidic water 4 Internal leakage in the heat exchanger 5 Low amount of material withdrawn from the side stream. Solutions: 1 Increase the amount of acidic gas withdrawn as much as possible while maintaining the temperature at the top of the tower. 2 Slightly raise the temperature at the bottom of the tower. 3 Stabilize the feed rate and determine the cause of changes in the concentration of acidic water. 4 If there is an internal leakage in the heat exchanger, use it as a bypass for maintenance purposes. 5 Increase the amount of material withdrawn from the side stream
