  • Patent number: 10934178
    Abstract: The disclosed embodiments relate to a system that performs low-temperature desalination. During operation, the system feeds cold saline water through a liquid-cooling system in a computer data center, wherein the cold saline water is used as a coolant, thereby causing the cold saline water to become heated saline water. Next, the system feeds the heated saline water into a vacuum evaporator comprising a water column having a headspace, which is under a negative pressure due to gravity pulling on the heated saline water in the water column. This negative pressure facilitates evaporation of the heated saline water to form water vapor. Finally, the system directs the water vapor through a condenser, which condenses the water vapor to produce desalinated water.

The vacuum-rated first chamber holds a quantity of non-potable water and a low pressure area less than or equal to the water's vapor pressure. Vaporization occurs when the higher temperature surface water is brought into contact with the low pressure area. A tubular vapor transport passage allows the vaporized water to pass to a lower temperature and lower pressure condensation chamber. The lower temperature condensation chamber is cooled by lower temperature water from a selected depth below the surface. As the temperature of the vapor lowers, the vapor will condense. This condensation is collected as a quantity of potable water. Additional embodiments and methods are also provided.

    Abstract: A method and device are provided for purifying and recycling water vapor from a coal drying process. Included are a temperature-lowering and dehumidifying process, a flash distillation stripping process, and a vacuum condensing process. A condensing tower receives a temperature-lowered exhaust gas with high humidity from a cooling tube and a condensed water of 5˜60° C. from a flash distillation tank, allowing the exhaust gas and the condensed water to contact each other in a vapor-liquid reverse manner, to lower the temperature and dehumidify the exhaust gas. The flash distillation tank performs a vacuum flash distillation to the condensing water pumped therein from the condensing tower. Water vapor of 5˜60° C. evaporated through flash distillation in the flash distillation tank enters into the demisting washer to be dehumidified and then is condensed. The condensed water in the vapor condenser is transferred into a recycled water tank. Non-condensable gas is discharged out.

  • Publication number: 20140262739
    Abstract: Embodiments relate to techniques for forming underground caverns, and also to desalinization processes that may be employed in conjunction therewith. Particular embodiments form a salt cavern by introducing heated water into a salt formation, followed by removal of the resulting brine to leave a salt cavern. The injected water is provided as a result of a desalinization process of the brine. Concentrated brine resulting from the desalinization process, is used to form a solar pond whose stored thermal energy provides the heat source for the injected water. The resulting underground cavern may be employed to house large volumes of materials such as pressurized natural gas, liquid hydrocarbons, or compressed gas for energy storage. Also disclosed is a particular desalinization process based upon a Regenerative Evaporative Distiller (RED) structure, which efficiently leverages low grade heat available from the solar pond by relying primarily upon a latent heat of evaporation and condensation.

  • Publication number: 20140262737
    Abstract: An apparatus and method for desalination use kinetic energy in ocean waves as a power source. The apparatus comprises a wave tank and a condensation tank, the wave tank and condensation tank being connected by two pipes, each with a one-way valve, that produced a cycle of water saturated air from the wave tank to the condensation tank with a return of relatively desaturated air back to the wave tank following condensation of water. The wave tank captures the up and down motion of the waves and converts it to a pumping action. Air inside the wave tank is compressed when a wave comes in and has a negative pressure when the wave recedes. A saline water spray is introduced during wave troughs. Water evaporates into the negative pressure air hydrating the air. When the next wave comes in the water level rises inside the wave tank pressurizing the air.

  • Patent number: 8696872
    Abstract: An improved water desalination system is disclosed, in which contaminated water such as seawater or brackish water is preheated and fed into a primary pressure vessel through a distribution head. The seawater is distributed from the distribution head over a non-adherent surface such as a plurality of silicone chords hanging below a distribution tank or a cone- and cylindrical-shaped surface. The water is exposed to a high temperature steam environment in the chamber to cause at least a portion of the water in the contaminated water to evaporate, while the remaining concentrated salts from the contaminated water fall to the bottom of the chamber. A portion of the steam in the primary pressure vessel is withdrawn to be condensed into fresh water. The energy withdrawn with the steam extracted from the primary pressure vessel is made up by a supplemental energy apparatus, such as a steam generator.

  • Patent number: 8647477
    Abstract: Water can be separated from a liquid composition (e.g., salt water) by directing a carrier gas flow through an evaporator and directly contacting the carrier gas flow with the liquid composition in the evaporator to humidify the carrier gas with water evaporated from the liquid composition, producing a humidified gas flow, which is then compressed by injecting a fluid that includes steam and/or an organic compound at an elevated pressure at least five times greater than the pressure in the evaporator and at a temperature at least as high as a saturation temperature of the steam/organic compound at the elevated pressure of the fluid. After being compressed, the humidified gas flow is directed through at least one condenser where water is condensed from the compressed humidified gas flow and collected; and the dehumidified gas flow is re-circulated back through the evaporator for reuse as the carrier gas.
