The minimum tray spacing in distillation column of diameter less than 3 ft is normally _____________ inches?
Correct answer: A. 6
- A. 6
- B. 18
- C. 24
- D. 34
Explanation
Small-diameter distillation columns can use closely spaced trays, with about 6 inches generally taken as the practical minimum. Larger columns require greater spacing to allow access, vapour disengagement, and maintenance.
