Falling Film Tubular Evaporator - Thermal Kinetics

Falling Film Tubular Evaporator - Thermal Kinetics

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

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. In the case of a falling film evaporator there is a series of vertical bundles of metal ...

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 Both rotary evaporators and falling film evaporators are capable of distilling solvent at a relatively high throughput, but one shines through as the clear front runner. An average rotary evaporator will typically have a throughput rate of 5-10 L/hour depending on the size of the condenser and flask, vacuum level, and condensing efficiency.
