Multiple Effect Evaporator - Concept Process Equipments

The Multiple Effect Evaporator (MEE) is an apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used [.]
