Falling Film Evaporator - Concept Process Equipments

Falling Film Evaporator - Concept Process Equipments

A Falling Film Evaporator (FFE) is a combination 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 Evaporator - Principle Construction And Working

Apr 16, 2022 A falling film evaporator is suitable for high viscous liquids because the flow of vapour film is assisted by gravity. The liquid hold-up is less and the hold-up time is very small. The liquid is not overheated during passage and heat transfer coefficients are high even at low boiling temperature. Highly acidic and corrosive feeds can be ...
