Bubble cap tray is the most commonly used tray in large distillation column, because______________?
Correct answer: B. Of its flexibility and nearly constant efficiency under varying conditions of operation
- A. It incurs less pressure drop as compared to any other try designed for the same duty
- B. Of its flexibility and nearly constant efficiency under varying conditions of operation
- C. It eliminates the foaming and entrainment tendency during operation
- D. None of these
Explanation
Bubble-cap trays tolerate a wide range of vapour and liquid flow rates while maintaining nearly constant efficiency, giving them good operating flexibility. Their pressure drop is comparatively high, and they do not eliminate foaming or entrainment.
