MEE MULTIPLE EFFECT EVAPORATOR | ATFD AGITAED THIN FILM DRYER

The salient features are:

Multiple effect evaporation, or MEE, involves structured sequencing of the evaporators, with the number of evaporators or effects commonly restricted to four, unless another specific design is required.

A multiple effect evaporator is an apparatus that efficiently uses the heat from steam to evaporate water.

In a multiple effect evaporator, water is boiled in a sequence of vessels, each of which is at a lower pressure than the last.

As the boiling point of the water decreases with pressure, the vapor produced in one vessel can be used to heat the next vessel.

Only the first vessel requires a source of external heat.

MEE is very simple in operation and the most proven system for evaporation. It is the least energy efficient of all evaporation types, however. The most important parameter for MEE is the feed effluent characteristic, which plays a major role in deciding the number of effects.
