Channelling is most severe_____________________?
Correct answer: A. In towers packed with stacked packing
- A. In towers packed with stacked packing
- B. In towers packed randomly with crushed solids
- C. In dumped packing of regular units
- D. At very high liquid flow rate
Explanation
Stacked packing tends to create preferential channels and poor liquid redistribution because the elements are arranged in continuous paths. Random dumped packing usually distributes liquid more effectively, so channeling is most severe with stacked packing.
