Multi Effective Evaporators

Multi Effect Evaporators are the equipment 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. The feed for the multi-effect type evaporator is generally transferred from one effect to another. This leads to the ultimate product concentration to reach only in the one effect of evaporator.
