An ideal tower packing should not _______________________?
Correct answer: D. Hold up large amount of liquid in the packing
- A. Have low weight per unit volume
- B. Have large surface area per unit volume
- C. Have large free cross-section
- D. Hold up large amount of liquid in the packing
Explanation
Packing should provide high area and free space while remaining light and retaining only a small amount of liquid. Excessive liquid holdup increases pressure drop and can promote flooding, so it is the property to avoid.
