Multi-Effect Evaporation is an important procedure adopted to economize the consumption of energy.
Multi Effect Evaporators are the instruments in which steam from an outside source is condensed in the heating element of first effect. The boiling temperature at which the first effect operates is high enough so that the evaporated water can serve as the heating medium for second effect. The vapors so formed are then sent to a condenser if it is a double effect evaporator.
