Falling Film Evaporator (FFE) -

Falling Film Evaporator (FFE) -

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 ...

Falling Film Evaporator Vs Rising Film Evaporator

Falling Film Evaporator Vs Rising Film Evaporator

A falling film evaporator is essentially a shell tube type of heat-exchanger used to evaporate heat sensitive liquids. The feed enters the evaporator through the top of the unit. It is then distributed evenly in the unit’s heating tubes. The liquid flows through tubes and forms a thin film on the walls of the tube while being partially ...

Rising Film Evaporator (RFE) Tubular Evaporators

A Rising Film Evaporator (RFE) is a vertical shell and tube heat exchanger with a vapor – liquid separator mounted at the top. The liquid to be concentrated is fed at the bottom of the heated tube bundle. As the liquid feed receives the heat, the vapors generated lift the liquid upwards. The velocities generated by the vapor lift are quite ...

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 Tubular Evaporator Thermal Kinetics

Falling Film Tubular Evaporator Thermal Kinetics

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 ...
