Mechanical Vapor Recompression

3R Technology offers MVR (Mechanical Vapor Recompression) for large volumes and energy economy. MVR is very energy efficient, since the latent heat of vaporization is fully utilized through vapor recompression and condensation. Typical layout of a MVR Evaporator is shown in figure.

Working Principle

Advantages and application

The major advantage of MVR is the energy economy. Typical MVR energy requirement is 0.05 to 0.15 kwh per kg of water evaporated. Water evaporation for a Triple Effect Evaporator to 120 kcal for a six effect evaporator. As the operating cost of MVR is low, large flow system favors its application in all sectors of industry and also desalination of sea and brackish water.
