Temperature at the middle of the packing layer in the single-tower pressurized side-stream extraction process?

The process involves extracting a side stream from the pressurized side of the tower; the temperature at the top of the tower is maintained between 40–50°C, while the pressure is between 0.5–0.53 MPa. The temperature of the side stream is 155°C, with little variation in these parameters. However, the temperature in the middle part of the packing layer fluctuates significantly, ranging from 60–110°C. Why is this? What should be the temperature at the middle of the filler layer in the tower, and does temperature variation have a significant impact on the quality of acidic gas and the purified water? What is the typical temperature in the middle of your packing layer? Please ask the experts to answer, thank you!
However, the temperature fluctuation in the middle of the packing layer is quite large, ranging from 60 to 110°C. Why is this? The tower top opening is too large, and the extraction ratio is unreasonable ； The ratio of cold feed to hot feed is unreasonable ； The side-line withdrawal is too small ； There are problems with the packing layer, resulting in poor mass and heat transfer. What should be the temperature at the middle of the filler layer in the tower, and does temperature variation have a significant impact on the quality of acidic gas and the purified water? Although it is not a critical indicator, it still indirectly reflects the operating condition of the distillation section of the stripping tower and the quality of the products obtained from each extraction point. What is the typical temperature in the middle of your packing layer? The temperature in the middle of our packing layer: 45-55°C.
