Multiple effect evaporation (MEE) Thermal vapor recompression (TVR) (also known as thermocompression) A combination of the three methods may be used depending on the process. For instance, a 3-effect evaporator circuit may be installed using MVR to transfer heat.
The best way to reduce energy consumption is by using multiple-effect evaporators. For multiple-effect evaporators, the steam from outside is condensed by the heating element of the first effect and the vapors produced from the first effect are then recycled back to the second effect, where the feed will be partially concentrated product of the ...
The best way to achieve high economies (which can be well over 100%) is to use multiple effect evaporator, whereby the vapour from one evaporator – or effect – is used to heat the feed in the next effect, where boiling occurs at lower pressure and temperature [3] Thermo-compression of the vapour, whereby the vapour will condense at a ...
A multi-evaporator system is a vapor-compression refrigeration system generally consisting of four major components: Evaporator; Compressor; Condenser; Thermal expansion valve; Sometimes in a refrigerator several loads are varied. Refrigerators used to function at different loads operated under different condition of temperatures and pressures.
Norbert Rillieux (March 17, 1806 – October 8, 1894) was a Louisiana Creole inventor who was widely considered one of the earliest chemical engineers and noted for his pioneering invention of the multiple-effect evaporator. This invention was an important development in the growth of the sugar industry.
Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination.It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto th
