Falling Film Evaporator - FFE / Evaporator | Concept

A Falling Film Evaporator (FFE) is a coination of vertical shell and tube heat exchanger and vapor- liquid separator mounted at bottom. The feed is given at top of shell & tube type heat exchanger having distributor. The liquid falling on distributor get distributed in such a way that it flow down as a thin film on inside surface of the tube.

Falling Film Tubular Evaporator | Thermal Kinetics

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a coination of the two.
