Falling film evaporation on the horizontal tube is a new technology for seawater desalination. Because the phase changes occur on both sides of film evaporation and the film flow of the liquid outside the tube contributes to speed up the separation of vapor and liquid, its heat transfer coefficient is high.

Falling Film Evaporation - an overview

Falling Film Evaporation - an overview

Falling film evaporators use gravity to convey the medium evenly over the heating surface from top to bottom and are therefore very energy efficient in operation. In the case of the plate falling film evaporator, the medium is passed over the heating surface of the plate bundle (1) heated from the inside in order to concentrate and evaporate it.
