Evaporation processes can operate under vacuum, atmospheric pressure, or positive pressure conditions. During the design phase, the most suitable operational method is selected by considering the specific properties of the product—such as viscosity, boiling point, and thermal sensitivity—to ensure optimal performance and efficiency.

The liquid to be evaporated is heated to its boiling point through a heat exchanger, according to the selected evaporation method. Evaporation then occurs across the vaporization surface created within the separator, allowing efficient phase separation and stable operation.

There are many types of evaporators, but the most commonly used systems in the chemical industry include:

• Falling Film Evaporators

• Forced Circulation Evaporators

• Multiple-Effect Evaporation Systems

• TVR (Thermal Vapor Recompression) Evaporators

• MVR (Mechanical Vapor Recompression) Evaporators
