The main reason for dividing a tall packed tower into series of small towers is to________________________?
Correct answer: D. Avoid channelling
- A. Minimise the overall pressure drop
- B. Avoid flooding
- C. Reduce liquid hold up
- D. Avoid channelling
Explanation
Dividing a tall packed tower allows liquid to be collected and redistributed between sections, preventing maldistribution and channel formation. It is therefore mainly done to avoid channelling rather than to eliminate flooding or pressure drop.
