Maximum allowable vapour velocity in a bubble cap tower is determined by the ____________________?
Correct answer: A. Entrainment considerations
- A. Entrainment considerations
- B. Vapour density
- C. Diameter of the column
- D. None of these
Explanation
The upper vapour-velocity limit in a bubble-cap tower is normally set by entrainment, where fast vapour carries liquid droplets to the tray above. Vapour density affects the calculation, but entrainment is the limiting operating consideration.
