Mechanical Vapor Recompression (MVRE) :

Mechanical vapour recompression (MVR) systems (also called MVR blowers) recover and reuse energy normally lost through evaporation. Because of the ability to use and upgrade wasted energy, MVR can significantly increase the efficiency of industrial heating and evaporation processes. MVR is a proven energy-saving evaporative concentration technology, which reduces evaporation energy use by 90% or more. MVR Thermodynamic Cycle. MVR uses energy recovered from the condensate to create a pure liquid distillate and a concentrated product/waste.

Advantages:-

Steam Consumption in MVRE is between 10 – 20 % of TVR based evaporator

It occupies 30 – 40 % of space required for Conventional MEE

The requirement of cooling water as utility is very less thus saving the energy required for cooling tower

The Opex (Power + Steam) for MVRE is 40 % less than the Opex (Power + steam) for conventional MEE

Since the steam condensate does not mix with the evaporated process condensate it does not add to the hydraulic load for upstream polishing treatment and so the polishing treatment becomes cheaper
