Check if the pressure in your tower is high
What is the significance of temperature control for the sensitive plate? Answer: In the plate-by-plate calculation of a distillation column, if it is found that the composition of the liquid on a certain plate changes significantly, the resulting temperature change will also be large. When changes occur during operation that disrupt the material balance, the temperature of that plate and the plates in that section are the most sensitive to such changes. In actual production, one of these plates is selected as the sensitive plate, using this temperature to control the changes in the material within the entire tower. It is generally chosen on the 8th to 12th boards from the bottom up. Advantages of controlling the temperature at this point: 1) Sensitive to changes, with accurate adjustment. 2) Identify material changes in advance and make adjustments proactively. ------------------------------------------------------------------ There is no fixed value for the temperature of the sensitive plate as mentioned by the poster; it changes depending on tower pressure, components, feed rate, and reflux rate.
