Larger depth of liquid on the trays of a distillation column_________________?
Correct answer: C. Both A. & B.
- A. Leads to high tray efficiency
- B. Results in higher pressure drop per tray
- C. Both A. & B.
- D. Neither A. or B.
Explanation
A deeper liquid layer generally improves vapour-liquid contact and tray efficiency, but it also increases the liquid head and therefore the pressure drop across each tray. Thus both stated effects occur, within the normal operating range.
