Can the efficiency of a plate in the distillation tower be greater than 100% ?
Correct answer: C. Never
- A. Yes
- B. Normally not; but is possible if infinite number of plates are put
- C. Never
- D. Yes; if the reflux ratio is maximum
Explanation
Plate efficiency is the actual separation achieved divided by the ideal equilibrium-stage separation, so it cannot exceed 100 percent. An infinite number of ideal plates may approach complete separation, but does not make an individual plate more than 100 percent efficient.
