What is the slope of the operating line in the stripping section of a distillation column ?
Correct answer: C. > 1
- A. 0
- B. ∞
- C. > 1
- D. < 1
Explanation
The stripping-section operating-line slope is normally written as the liquid-to-vapour flow ratio, L′/V′, and is conventionally greater than one for the usual distillation arrangement. The rectifying-section slope, in contrast, is generally less than one.
