Overall tray efficiency of a distillation column is the ratio of the number of ___________________?
Correct answer: B. Ideal trays required to the number of real trays required
- A. Overall gas transfer units to the number of ideal trays required
- B. Ideal trays required to the number of real trays required
- C. Real trays required to the number of ideal trays required
- D. None of these
Explanation
Overall tray efficiency compares the ideal number of stages with the actual number of trays: efficiency equals ideal trays divided by real trays. Because real trays are usually more numerous, the ratio is less than one.
