What is the slope of the feed line, if the feed to a distillation column is a saturated liquid ?
Correct answer: B. ∞
- A. 0
- B. ∞
- C. > 1
- D. < 1
Explanation
The feed-line slope is q/(q−1). For saturated liquid feed, q = 1, so the denominator becomes zero and the q-line is vertical, giving an infinite slope.
