The reflux to a distillation column is 100 moles/hr, when the overhead product rate is 50 moles/hr. The reflux ratio is____________________?
Correct answer: A. 2
- A. 2
- B. 0.5
- C. 50
- D. 150
Explanation
The reflux ratio is defined as reflux returned to the column divided by distillate withdrawn: R = L/D = 100/50 = 2. The product rate itself is not the reflux ratio.
