Weeping in a distillation column_____________________?
Correct answer: D. Results due to very low gas velocity
- A. Increases tray efficiency
- B. Provides large interfacial surface for mass transfer
- C. Results due to very high gas velocity
- D. Results due to very low gas velocity
Explanation
Weeping occurs when vapour velocity is too low to support the liquid on a tray, allowing liquid to leak through the tray openings. Very high gas velocity instead causes entrainment or flooding.
