  • Publication number: 20140150651
    Abstract: This invention provides a simple and energy-efficient process for obtaining water from air through better use of the solid desiccants using a high heating cycle in a confined space, applying minimal air flow and avoiding the use of a chilled condenser plate. The process of obtaining water in this invention consists of the production of water using, in one embodiment, a rotating drum covered with a desiccating material, a device that generates heat in a confined space, and a collection chamber. The process begins with charging the adsorbent material, which captures water vapor from the environment. Then, a discharging stage occurs through which an area of the desiccated material is exposed to controlled heating in a confined space, allowing the trapped water vapor to be released from the desiccant. A very light air flow may also be applied to increase the draw of the water vapor toward the area of condensation.

  • Patent number: 8500854
    Abstract: The disclosure provides a CO2 absorption method using an amine-based solid sorbent for the removal of carbon dioxide from a gas stream. The method disclosed mitigates the impact of water loading on regeneration by utilizing a conditioner following the steam regeneration process, providing for a water loading on the amine-based solid sorbent following CO2 absorption substantially equivalent to the moisture loading of the regeneration process. This assists in optimizing the CO2 removal capacity of the amine-based solid sorbent for a given absorption and regeneration reactor size. Management of the water loading in this manner allows regeneration reactor operation with significant mitigation of energy losses incurred by the necessary desorption of adsorbed water.

  • Patent number: 8268030
    Abstract: The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components. Those components transform the ambient wind portions into fast and cooled outflowing air portions. A decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water.

    Abstract: A self-regenerating bio-gas treatment system that uses the bio-gas instead of atmospheric are as media transport between adsorber and desorber tanks. Each tank includes at least four horizontally stacked and evenly spaced apart, perforated trays each capable being filled with fluidized carbon which migrates downward in the adsorber tank to remove contaminants from the bio-gas. With the bio-gas function as its media transport, the carbon media continuously moves downward over the perforated trays and eventually collected in the bottom of the adsorber tank. The spent carbon is then delivered to the desorber tank. The desorber tank is filled with an inert gas produced by an inert gas generator which causes the carbon media to be regenerated. The inert gas strips the carbon media of contaminates and is then delivered to a ground flare. The carbon media is returned to the adsorber tank and re-used to treat bio-gas.

  • Patent number: 7927406
    Abstract: The water droplet generating system includes a vessel, an opening/closing valve, a moisture absorbent member, and a condenser portion. The vessel has an opening portion. The opening/closing valve opens and closes the opening portion. The water absorbent member absorbs and releases water vapor depending on a change of humidity. The condenser portion is communicated with the inside of the vessel and cools water vapor released from the moisture absorbent member to be at a dew point of water vapor or less. When the opening portion is opened, the moisture absorbent member absorbs water vapor in atmosphere. When the opening portion is closed, the moisture absorbent member releases water vapor, and the condenser portion condenses water vapor, which is released from the moisture absorbent member, to generate a water droplet.

  • Patent number: 7563310
    Abstract: A dehumidifier for an electrical-equipment air intake has an outer housing wall and a floor of a material with a high specific thermal conductivity downwardly closing the outer housing wall, having a downwardly tapering funnel-shaped inner surface formed with a central downwardly open port, and having a rounded edge where the surface meets the port. An inner air-permeable housing inside the outer housing wall holds a moisture-absorbing mass so that air drawn in through the port can pass through the mass and then into a space between the inner and outer housings. A moisture sensor is provided between the housings and a heater in the mass. A controller connected between the heater and the sensor energizes the heater and cooks moisture out of the mass such that the moisture condenses on the floor and runs over the edge out through the port.

  • Publication number: 20090025711
    Abstract: A water vapor ejector comprises a desiccant disposed in a communication path to a green house enclosure. In the day time and under sunlight exposure, the green house enclosure heats up, which dries the desiccant and generates a flow to the outside ambient through a pressure difference. The moisture trapped in the desiccant is then released to the outside ambient. In the night time, the green house enclosure cools, which generates a flow to the inside of the enclosure. The desiccant traps the moisture within the flow, ensuring a moisture-free enclosure. The cycle re-starts in the next morning when the enclosure heats up. The diurnal cycle removes the water vapor present in the enclosure and delivered to the exterior of the enclosure.
