Falling Film Evaporator

We offer an assortment of Falling Film Evaporator that are robustly constructed and widely demanded in chemical industry and effluent treatment plants. Due to the turbulence created inside the chamber, the system is proved to be suitable for heat sensitive, highly viscous and moderately scaling liquids. Our range of falling film evaporator includes falling film, rising film, forced circulation systems.

 

Falling Film Evaporator

Our company is also engaged in the sphere of manufacturing and exporting a wide range of Falling Film Evaporator that consists of shell and tube heat exchanger. It the system the liquid is distributed and fed to the inside of the tubes of the calandria and create a uniform film.

Operation:


• The falling film evaporator consists of shell and tube heat exchanger called as calendria that is mounted in vertical position
• The liquid is distributed and fed to the inside of the tubes of the calendria and create a uniform film 
• The steam in the jacket heats the tubes thus causing the liquid in the feed to evaporate 
• The vapor is separated from the liquid in a vapor separator and the concentrated liquid is collected at the bottom or transferred to the next stage
• The falling film evaporator can be single effect or multiple effects depending on the capacity

 

Rising Film Evaporator

Leveraging on our industrial experience, we are manufacturing a wide range of Rising Film Evaporator that ensure the flow of the liquid upward in a parallel flow. Due to the increased vapor mount, it forms a "climbing" film on the walls of a tube it creates turbulence in the liquid that is suitable for heat sensitive, highly viscous and moderately scaling liquids. The high temperature between the heating chest and boiling chamber ensures uniform circulation and formation of a climbing film. These evaporators are flexible can be converted to Forced Circulation Evaporators easily.

Applications of Rising Film: 

• Chemical Industry
• Effluent Treatment Plants



Forced Circulation Systems

We offer Forced Circulation Systems that is used for various applications related to crystal growth and mother liquor de-supersaturation. The forced circulation systems is provided with a specially designed liquid vapor separation area that avoids formation of an excessive amount of fines, which is highly detrimental to crystal growth. 

Construction: 

• An "active volume", designed case by case, to get both required residence time for crystal growth and mother liquor de-supersaturation
• A given agitation (recirculation rate) rated to control the extent of super saturation arising from the evaporation, and to keep the temperature difference in the heat exchanger within reasonable limits
• Provided with liquid-vapor separation area to minimize the carry over losses and avoid the formation of an excessive amount of fines, which is highly detrimental to crystal growth
