RMP Lecture Notes - Christian Brothers University The key factor in determining the economy of an evaporator is the number of effects. The economy of a single effect evaporator is always less than 1.0. Multiple effect evaporators have higher economy but lower capacity than single effect. The thermal condition of the evaporator feed has an important impact on economy and performance.
