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 ...

Film Evaporation Technology - Sulzer

Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the

Falling film evaporator - Chemepedia

Falling film evaporator. First, we apply a differential mass (or mole balance) to both the gas side and the liquid side of the evaporator: which states that the change in the number of moles on the liquid side must show up on the gas side (or vice-versa). This results directly from conservation of …

Falling Film Evaporator - Swenson Technology

Falling film evaporators are ideal for heat-sensitive liquids because they allow evaporation to occur with an extremely low temperature difference between the process stream and the heating element. In addition, the liquid’s residence time within the evaporator is measured in mere seconds, making it suitable for concentrating products like ...

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 ...

Design Modelling and Simulation of Multiple Effect ...

Falling Film Evaporators: The falling film version of the long tube evaporator (Figure 1) eliminates the problems associated with hydrostatic head. Liquid is fed at the top of long tubes and allowed to fall down the walls as a film. This requires that temperature differences be relatively low.Vapor and liquid are usually separated at the ...

Delta Separations Falling Film Evaporator FFE- 45 Gal

Falling Flim Evaporation with the FFE. The Falling Film Evaporator (FFE) has its own take on the technology, incorporating improved features that keep the operator in mind. As a large portion of the tincture processed using a falling film evaporator is coming from a cold ethanol extraction, the design takes advantage of the cooling power that is already a sunken cost in the form of …

Falling-film evaporator - BMA

Falling-film evaporators allow advanced steam-saving concepts to be implemented for sugar production. This publication shares the experience and results of a full evaporator set with falling film evaporators in a cane sugar factory with particular view to scaling and non-condensable gases, which both have a
