The masters, come and take a look

The reasons why the exit temperature of the atmospheric pressure tower is higher than the bottom temperature of the tower may include the following: 1. Flow imbalance: The flow at the bottom of the tower is greater than the flow at the exit, resulting in an increase in the bottom temperature. It may be due to an excessive feed flow rate or poor reflux of vapor at the bottom of the tower. 2. Change in reactant substances: In a constant-pressure column, there may be a transformation of certain reactant substances, resulting in a higher temperature at the bottom of the column. This might be caused by certain chemical reactions. 3. Uneven heat transfer: Uneven heat transfer within the tower may occur, leading to an increase in the temperature at the bottom of the tower. It may be due to problems with the heat transfer conduit between the furnace outlet and the tower, or uneven heat transfer within the tower’s inner shell. 4. Measurement error: Errors in temperature measurement may lead to inaccurate display of the bottom temperature of the tower. Calibration or replacement of the temperature probe can be considered. Further analysis and inspection of the system are required to determine the specific cause. It is recommended to have professionals or relevant technical personnel conduct on-site inspections and analyses in order to arrive at accurate conclusions and take appropriate measures. .
