Effluent is feed to calendria using pump. Steam is subjected to calendria which heats up the effluent. The heated effluent will be flashed in vapour separator where liquid and vapours are separated. These vapours are compressed in the Mechanical vapour compressor to increase its temperature and pressure and routs to the claendria again.

In conventional evaporators, the energy content of the vapour stream produced is lost to a large extent or is only partially used. In comparison, mechanical vapour recompression permits the continuous recycling of this energy stream by recompressing the vapour to a higher pressure and therefore, higher energy content. Instead of live steam, electric energy is used indirectly to heat the plant.


Many multiple-effect evaporation plants have been installed all over the world during the past decades. They were either heated only directly with live steam or were equipped in addition with a thermal vapour re-compressor. Over the years, steam costs increased considerably in most regions. The optimum plant arrangement of the past in many cases is no longer efficient today, compared to state-of-the-art plants heated by means of electrically operated mechanical vapour re-compressors. In such a case, the question is how to compensate for this operating cost disadvantage. Increasing energy costs are to be expected also in the future. An increase of the number of effects to reduce the specific energy requirement often is not feasible. Therefore, a retrofitting to heating by means of mechanical vapour recompression should be evaluated.


1.       No excess heat source required. Only initial heat source is required and further the system generated the self heat by compressing the generated steam in the system.

2.       No external heat source required.

3.       No cooling water required

4.       Energy costs will be cut down.

5.       Reduces more Co2 imprints

6.       Environmental friendly.

7.       Reuse of the recycled water.
