Comparison to Conventional Processes
Mechanical Vapor Compression (MVC) is one of the most energy saving desalination processes as the heat is recovered.
Due to the low evaporation temperatures (< 85 °C), an increase of the vapor pressure (< 100 mbar) is enough to realize a temperature difference of 3 - 5 K for the total heat transfer. Hence, an effective heat transfer is taking place through the walls of the tubes.
In contrast to the direct evaporation of seawater, the MVC process requires only 2 - 3 % of the energy.
Energy input is directly proportional to the water output. This allows the plant to be directly powered by wind or solar energy, automatically adapting to the current power production, with no energy storage necessary.
