【Daily Question No. 281】October 14, 2018: Briefly describe the factors that affect the temperature at the top of an atmospheric pressure tower The factors that affect the top temperature of an atmospheric pressure tower are: 1. The amount of reflux at the tower top ； 2. Whether there is fluctuation in the reflux temperature ； 3. Does the reflux contain water? ； 4. Variation in feed temperature ； 5. Whether the feed rate is stable ； 6. Changes in the properties of the feedstock ； 7. Whether the cooler outlet temperature is stable ； 8. Is the feed water-containing? ； 9. Whether the tower pressure changes or not ； 10. Whether the instrument is easy to use. .
