In a forward feed multiple effect evaporator, the pressure is ____________________?
Correct answer: B. Lowest in last effect
- A. Highest in last effect
- B. Lowest in last effect
- C. Same in all effects
- D. Dependent on the number of effects
Explanation
In forward feed, the liquid flows from the first effect to successive effects while the pressure and boiling temperature are progressively reduced. Therefore, the last effect has the lowest pressure.
