To get high tray efficiency___________________?
Correct answer: B. Interfacial surface between liquid and gas phase should be large
- A. Time of contact between the two phases should be less
- B. Interfacial surface between liquid and gas phase should be large
- C. Gas velocity should be very low
- D. Liquid entrainment should be severe
Explanation
Tray efficiency improves when the interfacial area between gas and liquid is large, because mass transfer then has more area to occur. Short contact time, very low gas velocity, and severe entrainment all reduce efficiency.
