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

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 ...
