Falling Film Crystallization Evaporator

A Falling Film Evaporator (FFE) is a vertical shell and tube heat exchanger with a vapor- liquid separator mounted at the bottom. The liquid to be concentrated is fed at the top of the heated tubes and distributed in such a way that it flows down on the inside surface of the tubes as a thin film. As the film gets heated, the vapors generated flow co-currently.

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...
