Multiple effect evaporation is generally recommended, when the______________________?
Correct answer: A. Large scale evaporation of liquor is needed
- A. Large scale evaporation of liquor is needed
- B. Corrosive liquids are to be concentrated
- C. Fuel is cheaply available
- D. Evaporation on small scale is to be done
Explanation
Multiple-effect evaporation reuses the vapor from one effect as the heating medium for the next, saving steam in large-capacity operation. It is therefore most economical when evaporation is required on a large scale.
