Multi-Effect Evaporation is an important procedure adopted to economize the consumption of energy.
The Multi Effect Evaporators are designed to economize the consumption of energy. These are designed in such a way that the steam from an outside source is condensed in the heating element of first effect. Further for second effect the boiling temperature of first effect is just too high that evaporated water can serve as the heating medium. The formed vapors than send to condenser, if it is the double effect evaporator
But in the multi effect evaporators, the feed is generally transferred from the one effect to another, which leads to ultimate product concentration which further reaches to one effect of evaporator.
