Determination of the feed position in the distillation tower
Thread Content
How is the appropriate feed position for a distillation column determined?
The feed location should be on the tray that is closest to the feed composition.
The feed composition is closest to that of the tray, and the feed temperature differs little from the tray temperature.
Different feed compositions and temperatures both have an impact on the feed position. For details, see the chapter on distillation in the second volume of Principles of Chemical Engineering
Theoretically, you can use: 1. The McBratney-Teel method, abbreviated as M-T method! Also known as the graphical method! 2. If fed at the bubble point, the Fenske equation can also be used! Information on the east and west of western Zhejiang can be found in textbooks on chemical engineering principles!
