Falling Film Evaporation Of Single Component Liquids

Falling Film Evaporation Of Single Component Liquids

Aug 01, 2011 Heat transfer for single component falling film evaporation has been investigated in a stainless steel single tube falling film evaporator. The tube had a heated length of 2,500 mm. Propylene glycol and cyclohexanol have been used as evaporating media. Liquid film running down the tube, is formed on the inner side of the tube.

BT-16 Falling Film Evaporation of Ultra-Viscous Fluids HTRI

BT-16 Falling Film Evaporation of Ultra-Viscous Fluids. Phase III of Lehigh University’s falling film evaporation research focused on adding ultra-viscous film data to the existing database. The objective was to measure heat transfer coefficients for evaporating falling films with polymer solution viscosities up to 2419 lb/hr ft (1000 mPa s).

Climbing film evaporators are not suitable for the evaporation of viscous liquids. In the falling film evaporator, the liquid is fed to the top of a number of long heated tubes. Since gravity assists flow down the tube, this arrangement is better suited to the evaporation of moderately viscous liquids.

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 is suitable for high viscous liquids because the flow of vapor film assisted by gravity. The liquid is not over heated during passage and heat transfer coefficents are high even at low boiling temperature. Highly acidic and corrosive feeds can be concentrated using impervious graphite tubes rubber lined vapor heads.

Applications for Falling Film Evaporators - Fallfilmverdampfer

Falling film evaporators are used extensively in chemical process industry, food and paper industry. Due to the absence of static static head effect caused by liquid column as in other types of evaporators, evaporation can take place at very small effective mean temperature differences. The temperature diffference are tipically between 3 - 8C.
