Which of the following is an undesirable property in a tower packing ?
Correct answer: D. Large weight of liquid retained
- A. Large surface per unit volume
- B. Large free cross-section
- C. Low weight per unit volume
- D. Large weight of liquid retained
Explanation
A good packing should retain little liquid because excessive holdup increases pressure drop, inventory, and operating cost. Large surface area, large free cross-section, and low weight per volume are desirable properties.
