For the same feed, feed quality and separation (in a distillation column), with the increase of total pressure, the number of ideal plates will_____________________?
Correct answer: D. Increase
- A. Data insufficient, can't be predicted
- B. Decrease
- C. Remain same
- D. Increase
Explanation
Raising pressure generally lowers relative volatility for distillation systems, making separation more difficult. For the same feed and product specifications, this requires more theoretical plates.
