How does a falling film evaporator work
WebDec 7, 2024 · Falling film evaporators are vertical shell and tube heat exchangers used for the separation of at least two substances with different temperatures of boiling. These heat exchangers consist of two compartments. Their role is to bring the media, referring to a cooling or heating fluid, into indirect yet close contact with the process fluid, also ... Due to the intimate contact of the liquid with the heating surface, these evaporators are sensitive to fouling from precipitating solids. Low liquid velocity at the inlet is usually not sufficient to perform an effective self-cleaning of the tubes. Falling film evaporators are therefore used in clean, non-precipitating liquids. … See more A falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger.
