Tower diameter may be decreased by__________________?
Correct answer: B. Use of increased tray spacing
- A. Using higher reflux ratio
- B. Use of increased tray spacing
- C. Increasing the liquid flow rate
- D. Increasing the vapour flow rate
Explanation
Increasing tray spacing provides more disengagement space and permits a higher allowable vapour velocity before entrainment becomes excessive, so the required tower diameter can decrease. Higher reflux, liquid flow, or vapour flow generally increases the diameter requirement.
