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. Falling film evaporators are vertical in orientation, and have a bundle of metal tubes in a metal container. The metal tubes are then heated with a flowing media and the heat is transferred to the liquid mixture to evaporate the volatile component as the mixture flows down the tubes. Single stage falling film evaporators have high surface area and can be set to a single temperature.
