Tray spacing in a distillation column of dia 10-12 ft. used in petroleum refinery may be around _____________ inches?
Correct answer: B. 30
- A. 5
- B. 30
- C. 60
- D. 100
Explanation
Large-diameter petroleum-refinery distillation columns commonly use tray spacings of about 24 to 36 inches. Therefore, 30 inches is the practical estimate, while 5 inches is too small and 60 or 100 inches are unusually large.
