Mechanical Vapor Recompression (MVR) is the evaporation method by which a compressor is used to compress

and thus increase the pressure of the steam produced.

Since the pressure increase of the steam also generates an increase in the steam temperature,

the same steam can serve as the heating medium for the liquid being concentrated from which the vapor was generated to begin with.

This makes this evaporation method very energy efficient. When this compression is performed by a mechanically driven compressor,

the evaporation process is referred to as MVC (Mechanical Vapor Compression) or MVR (Mechanical Vapor Recompression).

Various combinations are possible, including single-effect recompression, multiple-effect recompression, 

multiple-stage recompression, and single-effect recompression combined with a multiple-effect evaporator.

The compression ratio required is comprised of three components which are: 

The boiling-point rise, i.e., the temperature of the boiling liquor minus the temperature of boiling water at the same pressure.

The Delta-T required for heat transfer.

The pressure drop in the vapor pipe to and from the compressor.

Mechanical recompression is not limited to single-effect evaporation. 

It is sometimes economical to compress vapor from the last effect of a double- or triple-effect evaporator so that 

the vapor can be condensed in the first-effect heat exchanger.

ZONTEN can design and supply many different types of equipment to achieve processing requirements. 

Our specialty is designing and installing innovative systems to convert liquid solutions into dry solids using evaporation, crystallization and drying. 

Please reach us & let us know your requirements. Full solution will be provided.

Looking forward to hear from you!
