For identical operating conditions, the pressure drop over _______________ tray is the highest out of the following?
Correct answer: D. Bubble cap
- A. Sieve
- B. Valve
- C. Counter flow
- D. Bubble cap
Explanation
Bubble-cap trays have risers, caps, and liquid seals that create greater resistance to vapor flow than sieve or valve trays under comparable conditions. They consequently produce the highest pressure drop here.
