Inside the distillation columns, the ________________________?
Correct answer: B. Driving force for the liquid flow is its weight
- A. Highest temperatures is near the feed plate
- B. Driving force for the liquid flow is its weight
- C. Vapors are not always at their dew points
- D. All A., B. and C.
Explanation
Liquid flows down a distillation column mainly because of gravity, so its driving force is its weight. The highest temperature is normally near the reboiler, not the feed plate, and actual vapour may not be exactly at its dew point.
