In the two photos below, you will see a power grid backup facility located in the southern United States. This facility is heavily guarded, in a secure location and its main purpose is to supply 50 megawatts of power to the grid.
This is for Waste Heat Freshwater Makers as outlined below, with the capability to produce over 60,000 gallons of water per day.
Model ST1200, Waste Heat Freshwater Makers (WHFM), are each rated at 1200 US GPH each. The evaporator, condenser, and tubes are 90/10 Copper Nickel. NEMA 4 Power and Control Panels, TEFC Motors, Marine Wiring, Piping and Insulation. The water produced from seawater will contain less than 5 ppm total dissolved solids.
Waste heat recovery desalination is a method of evaporating seawater by recovering the waste heat from the generator set jacket water and exhaust system, which would otherwise be discharged into the atmosphere. The heating media is circulated through a horizontal submerged "U" tube bundle in the lower section of the evaporator where a portion of its heat is transferred through the tubes and is utilized as heat of vaporization to boil the seawater. The evaporator operates under a vacuum, causing the seawater to boil at relatively low temperature. At the prevailing low temperature, scale precipitation is greatly reduced.
Steam produced by the boiling process travels through a woven mesh pad, which removes any en-trained water droplets. The dry steam then enters the condenser section, which houses the condenser tube bundle, through which cold seawater is circulated. Here the steam passes on the outside of the tubes, and is condensed into distilled water, which is extracted from the unit by the distillate pump. A conductivity meter is employed to measure the specific conductance of the distilled water, and if the conductivity is above a preset limit, the distilled water is diverted to waste.
Approximately 45% of the incoming seawater is converted into distilled water, while the balance becomes concentrated brine.
The concentrated brine and the non-condensable gases, which are given off by the boiling seawater, are extracted from the evaporator by water-motivated educators and discharged to waste. The system operates continuously once manually started.
The water produced is of very high quality, less than 5 PPM of totally dissolved solids, but may require post treatment disinfection if organics are present in the feed water and the distilled water is intended for human consumption. The Waste Heat Desalination Plant is self-contained, assembled on a rigid steel skid, completely piped, wired, and painted. The package consists of an evaporator shell with heating and cooling tube bundles, a distillate pump, educators for removing the concentrated brine and non-condensable gasses and for providing a vacuum for proper operation, all necessary valves and remote instruments, and a control / instrument panel for operator control.
