The mechanical vapor recompression (MVR)
evaporator has a method for recycling the steam
generated, thus eliminating the need for a source
of heat and cooling. A compressor is used to boost
the pressure of steam from the evaporator so that
it will condense at a higher temperature. This
enables the latent heat in the steam to be
returned to the evaporator, thus generating more
steam. In this way the same heat is reused. The
line of evaporators operates between 0.7 and 1.3
cents/gal of water evaporated at 7.5 cents/kw hr.
Standard designs operate from 20-2,000 gph. Since
the steam generated from the evaporation process
is condensed, there is said to be no exhaust
problems, air permitting, solution contamination
or air monitoring.
