EnconMechanical Vapor Recompression (MVR) Evaporator

SHARE

The ENCON MVR Evaporator is a forced circulation flash evaporator utilizing mechanical vapor recompression. Available in capacities from 300-4,000 gallons/hour, these highly Group-MVCautomated systems operate on steam and compressed air at a typical operating cost of $0.01-$0.02 per gallon of condensate. A variety of material of construction options are available to handle just about any waste stream.

Thermal separation processes such as evaporation and distillation can be energy intensive. In conventional evaporators, the energy content of steam vapor produced is lost to a large extent. Using mechanical vapor recompression in our MVR Evaporators permits the continuous recycling of this energy by compressing the steam to a higher pressure and temperature. This steam is then used to heat the mother liquid.

Mechanical Vapor Recompression not only greatly reduces energy costs, it also reduces the CO2 footprint. Of course, reduced energy costs doesn`t matter if you`re not getting the results expected. That is why ENCON custom designs and builds each MVR specific to the individual wastewater characteristics to provide the customer with the full purchased evaporation rate. The ENCON MVR Evaporator is designed for heavy duty industrial usage utilizing name brand, high quality components for long lasting performance and safety. Our four step mist-elimination process ensures the highest quality distillate.

MVR Evaporator Process Description

The ENCON MVR Evaporator is a forced circulation flash evaporator utilizing mechanical vapor recompression.

Evaporation is a process where water is removed from a feed stream to produce a concentrated discharge stream and a separate water stream.

A forced circulation flash evaporator utilizes a circulation pump to create a large circulation stream, and a pressure-reducing device (typically an orifice plate) to allow for flashing of the hot circulating stream.

In a Mechanical Vapor Recompression (MVR) evaporator heat is transferred to the circulating stream by condensing vapor from the compressor(s).
