Pressure drop through plate tower as compared to that through packed tower, for the same duty will be___________________?
Correct answer: B. More
- A. Less
- B. More
- C. Equal
- D. Either A. or B.; depends on the packing height
Explanation
For the same separation duty, a plate tower normally causes a greater pressure drop because gas must pass through liquid on every tray. Packed towers offer a more continuous open passage and therefore usually have lower pressure drop.
