The reason for preferring packed towers over plate towers in distillation practice is that the packed tower operation gives___________________?
Correct answer: C. Low pressure drop and low hold up
- A. Low pressure drop and high hold up
- B. High pressure drop and low hold up
- C. Low pressure drop and low hold up
- D. High pressure drop and high hold up
Explanation
Packed towers are preferred in many applications because packing provides gas-liquid contact with low pressure drop and relatively low liquid holdup. Plate columns generally have greater pressure drop and liquid holdup.
