  • Publication number: 20120318659
    Abstract: A method and apparatus for dehydration of glycol uses two galvanic electrodes submerged in a water-glycol mixture. Semiconductor switches are used to supply pulses from a direct current source and to control the polarization and current flow time in such a way as to produce an average current of zero and a switching frequency commensurate with electro-hydrodynamic frequency of the electrode and liquid system. By applying sufficiently low frequency of switching, stirring of glycol and removal of gas products from the electrodes is achieved. The glycol container has at least one submerged electrode module equipped with at least two galvanic electrodes. Each electrode is connected through pairs of high power electronic switches which cycle alternatively between the positive and negative terminals of a direct current power supply.

  • Patent number: 7866176
    Abstract: An autonomous water source for extracting water from ambient air and delivering it to a plant to support growth. The system is based on an adsorption-desorption-condensation cycle using a sorption material to extract moisture from ambient air and condensing the water vapor driven off from the sorption material by subsequent heating and followed by condensation. Liquid condensate produced in this process on the condenser is collected and delivered by gravity to a plant to reduce thermal stress and to support growth. The invention provides a sustainable source of irrigation water for agriculture and forestry, including areas where no water resources exist or are not economically viable. It can be tailored in size, and therefore, output capacity, reflecting the desired water requirements of a particular application, and can be used to replace most agricultural situations now reliant on surface water drip feed systems.

The outer tube is preferably made of a material that readily absorbs solar radiation and is a good heat conductor. There is a gap between the inner tube and the outer tube for the flow of air. The inner tube contains a flow of impure water. The hydrophilic membrane allows water to pass to the outside of the inner tube as vapour, but prevents impurities from passing through. Air flowing in the gap takes up the water vapour and humidified air exits the evaporation device. This humidified air is subsequently cooled to collect the vapour and provide purified water, e.g. at a condenser.

  • Publication number: 20090277769
    Abstract: A water still having an evaporative chamber containing the liquid water. When the evaporative chamber subjected to solar provided heat the water vaporizes and then condenses on the condensing plate where the condensed water flows to a collection reservoir. The condensed water contacts solid essential minerals or precious metals to “re-mineralize” the condensed water. The condensed water is contained within the heated evaporative chamber to force suspended volatile gases to be exhausted from the water.

  • Patent number: 7572352
    Abstract: Salt-containing water is desalinated by first passing salt-containing water through a heat exchanger disposed in a basin containing solar-heated brine formed by several layers of water lying one above the other in the basin, each of the layers of water forming the brine having a higher salt content than the layer present there above. The heat exchanger is in the lowermost layer of water having a higher temperature than the temperature of the layers of water lying above the lowermost layer of water. The salt-containing water is heated in the basin by solar energy indirect heat exchange with the solar-heated brine to obtain heated salt-containing water. At least part of the heated salt-containing water is evaporated to obtain water vapor, and the water vapor is condensed to obtain desalinated water.

  • Publication number: 20090107831
    Abstract: The present disclosure is generally directed to a solar distillation system capable of recovering potable water from non-potable water. In certain embodiments, the system includes a substantially air tight solar still having a roof top composed of a solar light-transmitting material. The solar still includes a tube positioned below and running underneath the roof top, the tube having an exit end. Additionally, the solar still includes a heating surface positioned below the roof top and adapted for receiving at least a portion of the non-potable water exiting the tube at the exit end. Non-potable water on the heating surface is solar heated and a portion of the non-potable water evaporates and condenses on the outside of the tube to be collected as potable water.

  • Publication number: 20090065345
    Abstract: A method and a device for purifying 1,4-bis (bromodifluoromethyl) benzene are disclosed. In order to solve the problem of hard to purify and separate 1,4-bis (bromodifluoromethyl) benzene crude products, diphenylmethane that has a higher boiling point and does not interact with 1,4-bis (bromodifluoromethyl) benzene is mixed with the 1,4-bis (bromodifluoromethyl) benzene crude products for evaporation. Afterwards, the purity of the vaporized product is detected and only that reaching an expected purity is collected to obtain high-purity 1,4-bis (bromodifluoromethyl) benzene.

  • Patent number: 7501046
    Abstract: An evaporation sleeve is placed within a solar distillation loop apparatus to increase the amount of water evaporated by the apparatus. The evaporation sleeve is rotationally attached within the above ground portion of the solar distillation loop so the sleeve lifts impure water into the air flow within the system. The evaporation sleeve significantly increases the water surface area available to the air flow within a solar distillation loop.

  • Publication number: 20090057127
    Abstract: The present invention provides a novel tritium distillation device, which comprises a container, a radiator covered on top of the container with a protrusion at the bottom, a conduit penetrating the container with an inlet and an outlet, the inlet being arranged in correspondence with the protrusion, and a heating device fixed below the container. The method of operating the tritium distillation includes the steps of adding environmental tritium in the container, covering the radiator on top of the container closely, heating environmental tritium to cause tritium steam to be condensed to the bottom of the radiator, and collecting the tritium condensation dropped from the protrusion with conduit. The present invention uses a simple structure to ease assembly and reduce the cost of cooling water source.

  • Patent number: 7491298
    Abstract: A plant and process for efficient production of low deuterium water from seawater. The plant includes a solar still with a black pan for collecting solar heat, that vaporizes portions of the seawater and a porous sloped membrane positioned over the black pan to collect and condense the vapor and to direct the condensate via gravity to a condensate tank. The condensate water is separated into its atomic components, hydrogen and oxygen, in an electralizer; then the hydrogen and oxygen are combined in a reactor to produce heat and low deuterium water. In preferred embodiments the reactor is a fuel cell which in addition to the heat and water also produces electricity. At least a portion of the heat produced in the reactor is used in the solar still to assist in the vaporization of the seawater and to greatly increase the efficiency of the still.

  • Patent number: 7467523
    Abstract: An autonomous water source (AWS) for extracting water from ambient air and delivering it to a plant to support growth. The system is based on an adsorption-desorption-condensation (ADC) cycle using a sorption material to extract moisture from ambient air and condensing the water vapor driven off from the sorption material by subsequent heating and followed by condensation. Liquid condensate produced in this process on the condenser is collected and delivered by gravity to a plant to reduce thermal stress and to support growth. The invention provides a sustainable source of irrigation water for agriculture and forestry, including areas where no water resources exist or are not economically viable. It can be tailored in size, and therefore, output capacity, reflecting the desired water requirements of a particular application, and can be used to replace most agricultural situations now reliant on surface water drip feed systems.
