Falling Film Evaporators Automated Solvent Recovery

Falling Film Evaporators Automated Solvent Recovery

A falling film evaporator is a specialized type of ‘shell and tube’ heat exchanger that is used to separate different substances or solvents with different boiling temperatures. These devices are highly efficient and effective and can achieve lightning-fast evaporation rates. Factories and labs across the country have been updating old ...

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 ...
