Evaporation is the process, which involves thermally removing a liquid from a solution, suspension or emulsion. The starting and the end products are in the liquid phase and the end product obtained is in its concentrated from. Depending on the liquid characteristics to be concentrated, its temperature sensitivity, thermal degradation properties etc different types of evaporators have been designed and are used for variety of applications in different industries. Single stage systems are employed, where the vapour energy of one stage is used as the heating media for the next stage. Further efficiency increase is obtained by using Thermal Vapour Recompression system or Mechanical Vapour Recompression system.
Falling Film Evaporator
As the name indicates the product is fed to the inside surface of a large number of tubes through which it passes downwards forming a thin film. The steam enters the jacket surrounding the tubes and leaves at the bottom as condensate. The product inside the tubes boils, and the vapour accelerates to the bottom and separated in vapour separator. As the entire system is working under Vacuum Evaporation, temperature is very low (below 100 Deg C) and thus the system can be applied for heat sensitive products.

Forced Circulation Evaporator
These could be horizontal or vertical. The fluid is forced under pressure through the tubes and are useful in handling slurries too.

Hybrid Evaporator
Depending upon the process conditions, the type of evaporator is selected. Many a times, combination of stages is reuired or Hybrid evaporators are designed based on the process progress.
Steam is normally the heating media, however, thermic fluid and other sources are also used. Waste heat recovery heat exchagers can also be offered.
APPLICATIONS OF HYBRID EVAPORATORS

Natural Circulation Evaporator
Natural Circulation Evaporators are vertical evaporators where the evaporation is induced in the tubes, thereby the vapor forcing the liquid to form a thin film along the walls of the tubes.
As thermal energy is used in evaporation and with its increasing cost, it is important to optimize upon the operating costs. Multistage designs help achieve reduced operational costs. Energy is applied to the first stage of the evaporator. Vapor from this stage is reused in the next stage as the heating media. Similalrly, from the second stage, vapors are used as heating media in the third stage and so on. Evaporators upto seven stages are designed, based on the product properties.
For further energy efficiency, Thermal Vapor Recompression system or Mechanical Vapor Recompression systems are used.
