Falling Film Evaporators: Principles And Applications - ALAQUA

Falling Film Evaporators: Principles And Applications - ALAQUA

A falling film evaporator is a type of heat exchanger that uses a shell and tube design to evaporate heat-sensitive liquids. The feed is pumped into the evaporator from the top. It’s then uniformly dispersed throughout the heating tubes of the device.

A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires 0.09 kg of steam. Without the thermocompressor, the specific steam consumption would be approx. 0.55 and 0.2 kg per kg of water evaporation respectively.

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 ...

Falling Film Evaporation - an overview

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.

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. In the head, the product is evenly distributed into the heating tubes. The liquid enters the heating tube and forms a thin film on the tube wall where it flows downwards at boiling temperature and is partially evaporated.

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 As the name “falling film” implies, the mixture flows down the side of the tube to create a thin film for evaporation. Because of this, mixtures with a lower overall viscosity are most compatible with the fracTron while higher viscosity mixtures work best with wiped film evaporators like extraktLAB’s clearSTILL 400. However, the fracTron ...
