Falling Film Evaporator forced film evaporator -Shachi Eng

Falling Film Evaporator forced film evaporator -Shachi Eng

A falling film evaporator is essentially a shell tube type of heat-exchanger used to evaporate heat sensitive liquids. The feed enters the evaporator through the top of the unit. It is then distributed evenly in the unit’s heating tubes. The liquid flows through tubes and forms a thin film on the walls of the tube while being partially ...

Thin Film Evaporator Design - WKIE

A thin film evaporator has an extremely complex build and design but has some primary components which facilitate distillation of highly volatile mixtures. These are made of glass or metal, more often than not stainless steel. Glass tends to be cheaper while stainless steel tends to be durable and is more suitable for larger evaporators.

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.

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. In the head, the product is evenly distributed into the heating tubes. The liquid enters the heating tube and forms a thin film on the tube wall where it flows downwards at boiling temperature and is partially evaporated.

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced.
