Desalination of sea water is becoming more urgent for many regions. In the coming decades water will be used for desalination from various reservoirs of the World Ocean. It is important to determine the operating modes of desalination plants, which ensure the minimum cost of desalinated water at different salinity of sea water. Mathematical modeling of the desalination plant with mechanical vapor compres-sion (MVC) is carried out. It has been established that for each sea water salinity there is an optimum salinity value of the boiling brine in the evaporator. An approximating dependence was obtained for calculating the optimal salt content.
