In a continuous distillation column, the optimum reflux ratio ranges from _______________ times the minimum reflux ratio?
Correct answer: A. 1.1 to 1.5
- A. 1.1 to 1.5
- B. 1.6 to 2
- C. 2.2 to 2.6
- D. 2.7 to 3
Explanation
Operating reflux is commonly selected at about 1.1 to 1.5 times the minimum reflux ratio, balancing equipment size against energy consumption. Very high reflux reduces stages but increases reboiler and condenser duties.
