Which of the following factors determine the amount of entrainment in a distillation column ?
Correct answer: C. All A., B. and C.
- A. Plate spacing
- B. Depth of liquid above the bubble cap slots
- C. All A., B. and C.
- D. Vapour velocity in the volume between the plates
Explanation
Entrainment depends on tray geometry and operating conditions: plate spacing and liquid depth affect droplet carryover, while vapour velocity provides the force that carries droplets upward. Therefore, all three factors contribute.
