The slope of operating line in the rectifying section of a distillation column is unity, if the reflux ratio is___________________?
Correct answer: B. ∞
- A. 0
- B. ∞
- C. 1
- D. Minimum
Explanation
The rectifying-line slope is R/(R+1), where R is the reflux ratio. This approaches unity only as R becomes infinite, corresponding to total reflux.
