boiling at lower part of the tube. The LTV evaporators are commonly used in concentrating black liquors in the paper and pulp industries. 4. Falling Film Evaporators In a falling film evaporator, the liquid is fed at the top of the tubes in a vertical tube bundle. The liquid is allowed to flow down through the inner wall of the tubes as a film.

What is a Thin Film Evaporator Thin Film Evaporators

Evaporator equipment is typically designed to produce a thin film on a heated surface so that solvents will volatilize quickly and efficiently. Condensation is the process of changing a vapor or gas into a liquid. The liquid in this case is called a condensate. The term thin film is also applied to a condenser because as condensable vapor gas ...

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 ...

How Marangoni stress affects falling films HTRI

The short answer: it is all about Marangoni stress and evaporation, both of which are linked to falling film evaporation. Carlo G. M. Marangoni, a high school physics teacher, was the first to give a rigorous explanation of the “tears of wine” phenomenon. He formulated a theory for flows driven by surface tension gradients due to variations ...

Working principle. For the thermal separation of a mixture a thin film is produced at the heated wall of a cylindrical or conical evaporator. A distribution ring on the rotor distributes the liquid evenly across the periphery. Then, the blades fitted at the rotor spread the liquid as a thin film of min. 0.5 mm over the heat transfer surface.
