摘要:
The invention relates to a plant for desalinating sea water by multi-effect distillation (MED) with thermo-vapor compression (TVC) to be coupled to a thermal power plant, comprising a series of distillation cells (A, B, C, D, E) each operating at a temperature and a pressure that are lower than those of the preceding effect, and comprising a thermocompressing means enabling the compression of a portion of the water vapor emitted by one of the effects (E) and the reinjection into the first effect (A). The invention is characterized by the fact that the thermocompressing means (6) is designed in such a manner that it can operate alternately at two different live vapor VM pressures. The invention also relates to a method for desalinating sea water while using a plant of the aforementioned type.

摘要:
The invention relates to a sea-water desanilation facility using multiple effect distillation (MED) with mechanical and thermal vapour compression (MTVC), which facility is intended to be coupled to a thermal power plant and includes (A) a series of distillation cells (stages A, B, C, D, E), each operating at a temperature and at a pressure lower than the preceding stage, and (B) a vapour compression means for compressing the water vapour emitted by the last stage and reinjecting same in the first stage, wherein the vapour compression means consists of a parallel-mounted, alternately operating thermocompressor (6) and mechanical compressor (9) and said facility further includes (a) a heat discharge means (8) and first (11) and second (10) heat recovery means. A sea-water desalination method using such a facility is also described.
