What is the multiple effect evaporator theory?

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.

How does a mee plant work?

Multiple Effect Evaporator (MEE) is a system consists of a sequence of heat exchangers – VLSs (vapor-liquid separators) used widely for many applications in industries to achieve evaporation and obtain desired concentration as output by using an efficient amount of heat source such as steam or hot water to evaporate ...

What are the calculation methods for multiple effect evaporators?

The calculations are done using material balances, heat balances, and the capacity equations q = UAAT for each effect. A convenient way to solve these equations is by trial and error.
