摘要
The invention relates to a multi-effect distillation (MED) sea water desalination plant with thermocompression of steam (TVC), intended to be coupled to a thermal power station, comprising a series of distillation cells (A, B, C, D, E) each operating at a temperature and pressure lower than those of the preceding effect and a thermocompression means for compressing a part of the water vapor emitted by one of the effects (E) and injecting it back in the first effect (A), characterized by the fact that the thermocompression means (6) is designed so as to be able to operate, alternatively, at two different VM driving steam pressures, as well as a water desalting process. sea using such an installation
