In the field of thermal separation / concentration technology, evaporation plants are widely used for concentration of liquids in the form of solutions, suspensions, and emulsions.

The major requirement in the field of evaporation technology is to maintain the quality of the liquid during evaporation and to avoid damage to the product. This may require the liquid to be exposed to the lowest possible boiling temperature for the shortest period of time.

This and numerous other requirements and limitations have resulted in a wide variation of designs available today. In almost all evaporators the heating medium is steam, which heats a product on the other side of a heat transfer surface. the most common types of evaporators are following under.

• Falling Film Evaporators 
• Rising Film Evaporators
• Forced Circulation Evaporators 
• Plate Evaporators
• Compact Evaporators 
• Thermal and Mechanical Vapor Recompression (TVR & MVR) 

 Applications

• Product concentration 
• Dryer feed pre-concentration 
• Volume reduction 
• Water / solvent recovery 
• Crystallization
