Falling Film Evaporation - an overview

Falling Film Evaporation - an overview

Falling film evaporators are largely used to remove a solvent from a liquid mixture by evaporating the more volatile component. Compared to wiped film evaporators, falling film evaporators: have a higher heated surface area per footprint, are less equipped to distill highly viscous mixtures, and are much better equipped to distill a solvent at a high throughput.
