Falling film evaporator rules of thumb

WebAug 1, 2007 · The design of falling film evaporators is often based on empirical correlations and rules of thumb, especially for the maximum heat flux and minimum liquid load. When designed at the borderlines of established operating regions significant over-design may be found. This can largely be attributed to a limited database.

WebA 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 … WebThe product feed enters through the top and the, via a distribution system, is equally distributed to each of the tubes. The liquid film moves downward due to the effect of gravity, during the fall through the tubes the volatile fraction is evaporated and leaves the equipment through the top or the bottom, depending on the equipment configuration. t6 tokens for s3 gear
