Falling film flow -

A falling film is the gravity flow of a continuous liquid film down a solid tube having one free surface. Other geometries and conditions are possible variables, 1 but normal practice is with a vertical tube and countercurrent gas flow. Falling films are used in industry for distillation, absorption, reactions, condensation, etc. 1 Its advantages are that liquid residence time is …

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 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 ...

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...

May 01, 2021 In falling film devices, this process happens at the liquid-vapor interface. It means that the device can use a lower temperature, meaning less energy use and some other benefits. For example, as there is no nucleate boiling on the tube walls, the solution in the evaporator will not crystalize. These long-tube devices are very energy efficient ...
