Reflux ratio variation in a distillation column is between___________________?
Correct answer: A. Minimum and infinity
- A. Minimum and infinity
- B. Zero and one
- C. Zero and infinity
- D. None of these
Explanation
For a feasible distillation separation, the operating reflux ratio must be at least the minimum reflux ratio; at total reflux, it approaches infinity. Thus its practical range is from minimum reflux to infinity.
