Vapor Compression is a
prepackaged closed loop distillation system designed to treat a wide variety of
wastewater and process water streams through the use of advanced vapor
compression/distillation technology.
Extremely low energy costs
are achieved utilizing the process cycle where the treated water stream is
vaporized, compressed and finally condensed to produce a high concentration of
recoverable materials and distilled water. The low energy requirements are
achieved by the efficient recycling of latent heat normally lost during the
evaporation process.
THE PROCESS
1. The wastewater entering
the system is preheated, and gross solids removed.
2. The wastewater is circulated
through a specially designed plate and frame heat exchanger where the water is
boiled into vapor. A mixture of water and vapor exit the heat exchanger and
enter the separator.
3. The compressor draws the vapor from the separator and compresses it to
about 5 psi, thereby increasing its temperature. The superheated vapor is then
pumped into the condenser side of the heat exchanger where it is used to boil
additional water in the evaporator side. As the hot vapor releases its latent
heat, it condenses into distilled water, which is then discharged from the
system.
4. As
additional water is evaporated during the process, the
remaining water becomes more concentrated. When the desired
level of concentrate is reached, the concentrate is
discharged, and more feed stock is added automatically to the
system. The System treats industrial process and wastewater
streams. It combines the benefits of distillation with those
of vapor compression, the system has a wide range of
applications and provides substantial economic and operational
benefits to the user. Depending on local energy charges and
the volume of liquids being processed, energy costs can be as
low as ½ cent per gallon.
