What is a multiple effect evaporator system?
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 is a multi-effect evaporator for ZLD?
The Multiple Effect Evaporator (MEE) / Zero Liquid Discharge (ZLD) 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.
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.
Concentrated black liquor has high viscosity, which can cause significant problems with fouling if these characteristics are not accounted for in system design.
