VAPOR COMPRESSION DISTILLATION is a system that treats industrial process water and waste-water streams. The System combines the benefits of distillation with those of vapor compression to greatly lower the cost of distillation for removal of water or concentration of other ingredients. It can be used for a broad range of applications and provides substantial economic and operational benefits to the user. Depending on local energy cost and the volume of liquids being processed, energy costs can be less than a penny per gallon.

Vapor Compression is a prepackaged closed loop distillation system designed to treat a wide variety of waste-water 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

The waste water entering the system is preheated, and gross solids removed.

The waste water 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.
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.
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 waste-water 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.
