Reason for operating an evaporator in multiple effects is to secure ___________________?
Correct answer: C. Both A. and B.
- A. Increased steam economy
- B. Decreased steam consumption
- C. Both A. and B.
- D. Increased capacity
Explanation
In a multiple-effect evaporator, vapor from one effect heats the next effect, allowing the same steam to evaporate solvent repeatedly. This raises steam economy and reduces steam consumption per unit of evaporation.
