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 Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the

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 ...

Unlike wiped film evaporators, this unit has no moving parts, reducing both capital and operating costs. Under normal operation, feed liquor and the heating medium are directed to alternate passages formed by the positioning of heat transfer plates within the evaporator. As the feed contacts plates heated by steam or hot water, boiling occurs.
