  2. Vapor-compression evaporation - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_evaporation

    If compression is performed by a mechanically driven compressor or blower, this evaporation process is usually referred to as MVR (mechanical vapor recompression). In case of compression performed by high pressure motive steam ejectors , the process is usually called thermocompression , steam compression or ejectocompression .

  3. Mechanical vapor recompression - Wikipedia

    en.wikipedia.org/wiki/Mechanical_vapor_recompression

    Mechanical vapor recompression (MVR) is an energy recovery process which can be used to recycle waste heat to improve efficiency. [ 1 ] [ 2 ] Typically, the compressed vapor is fed back to help heat the mother liquor in order to produce more vapor or steam.
