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 ...

Evaluation of a MVR versus TVR heated falling film finisher

Aug 17, 2015 However, the capital costs are significant for an MVR turbofan – while the TVR steam ejector would cost roughly $15,000, the MVR turbofan would cost almost $250,000 taking the additional installation cost and increase of the finisher heating surface area into account. This is a 16 fold increase in up front capital costs for the compression ...

3-2 Black Liquor Evaporator Design and Operation - TAPPI

3-2 Black Liquor Evaporator Design and Operation - TAPPI

Falling Film (FF) Evaporators This evaporator design relies either on tubes or plates as heat transfer surfaces. Liquor is processed on the inside of the s in tubular units but on the outside of the heat transfer surface in plate designs. FF evaporators consist of a liquor sump from which a defined volume of liquor is continuously recirculated to
