In a backward feed multiple effect evaporator ___________________ ?
Correct answer: B. Feed flows from low pressure to high pressure
- A. Feed is introduced in the first effect
- B. Feed flows from low pressure to high pressure
- C. No pumps are required between successive effects
- D. None of these
Explanation
In backward feeding, fresh feed enters the last, low-pressure effect and moves toward the first, high-pressure effect. Pumps are therefore needed between effects, making feed flow from low pressure to high pressure.
