A Falling Film Evaporator 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, under the influence of gravity. As the film gets heated, the vapors generated flow co-currently. The drag of vapors increases the turbulence and improves heat transfer performance. The balance liquid and vapor are separated in the vapor- liquid separator.
