Very tall packed towers are divided into series of beds to___________________?
Correct answer: B. Avoid channelling
- A. Reduce the overall pressure drop
- B. Avoid channelling
- C. Reduce liquid hold-up
- D. Avoid flooding
Explanation
Very tall packed towers are split into beds with liquid redistributors so that liquid is spread uniformly again. This prevents maldistribution and channelling, whereas flooding is controlled mainly by flow rates and packing capacity.
