  • Patent number: 9005349
    Abstract: A system and method to recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. Fans, valves, and manifolds are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. The airflow within the chamber and/or each tray is altered depending upon the settings of configurable airflow manifolds. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.

    Abstract: Provided is an air drying system that includes a desiccant container including desiccant material for removing moisture from a pressurized air stream directed through the container in a first direction, a heater coupled to the container for selectively providing heated air to the container in a second direction opposite the first direction, and an air source coupled to the container for selectively providing cooled air to the container in the first direction. By introducing the cooled air in the opposite direction as the heated air, the duration of the cooling can be extended to allow for further removal of adsorbed moisture from the desiccant, thereby lowering the dew point. The extended duration of cooling also allows for additional removal of heat from the desiccant container to minimize heat spikes when the desiccant container is switched to the adsorbing cycle.

  • Publication number: 20140202335
    Abstract: A system for increasing the power of cars by increasing the oxygen content in the intake manifold supply using a zeolite filtration system. This system does not rely on the conventional method of injecting pure oxygen from a tank or using hydrolysis from water. This actually converts the air to a higher oxygen content as it flows to the intake manifold in a car. The practical idea of this is to increase the power of the engine without increasing displacement or to have the engine downsized with less displacement while still having the same power. It also has the application in cars or trucks to almost completely diminish NOx emissions. This is especially useful in tractor trailers because then you can forgo expensive aftertreatment systems to reduce NOx, which sometimes cost more than the engine itself, greatly reducing the cost of a tractor trailer and also doing the things mentioned above.

The desiccant is held in pores or fibrous entraining areas sized ranging from 50 microns to 1000 microns. Thin sheets are arranged in a stack in a multi-chamber system, while in an absorption state, uses this stack in a main chamber to absorb H20 from atmospheric gas flowing through that chamber. In a regeneration state atmospheric flow is stopped and low-grade energy releases the H20 from the desiccant into that chamber. Fans circulate moist air through the main chamber and into an adjacent chamber for H20 transfer through or past a partially permeable barrier into a cooling/condensing area. Both H20 and dry gas may be produced.

  • Patent number: 8500878
    Abstract: The invention pertains to an inerting system for an aircraft featuring at least one air separation module with at least one air inlet, a first air outlet and a second air outlet. The air separation module is designed for splitting an input air flow into a first air flow and a second air flow, wherein the first air flow is enriched with oxygen in comparison with the input air flow and discharged at the first air outlet and the second air flow is enriched with nitrogen in comparison with the input air flow and discharged at the second air outlet. In comparison with known inerting systems, the inerting system according to the invention is characterized in that the air inlet can be connected to an air extraction point in an air processing system and the inerting system is designed for routing the first air flow into a cabin to be air-conditioned.

  • Publication number: 20130174729
    Abstract: A method for indirectly monitoring and controlling an electrically resistive adsorption system. Adsorption of a predetermined adsorbate is conducted while indirectly monitoring electrical resistance of a unified adsorbent element. Breakthrough is predicted based upon the indirectly monitored electrical resistance and a previously measured mass loading relationship between the resistance of the unified adsorbent element and the loading of the unified resistance element with the predetermined adsorbate. Adsorption, regeneration and cooling cycles are controlled by a controller without any direct measurement of temperature or resistance of the element and characterizations of mass loading and temperature. Systems of the invention can have no sensors that contact the element, are in an adsorption vessel, and/or are downstream adsorption vessel.

  • Patent number: 8480786
    Abstract: Information used for creating an adsorption isostere of a substance to be measured in a measuring system (container) is obtained by repeating alternately a first control step of changing temperature or pressure of the measuring system by a fixed amount by adjusting a gas amount supplied to/discharged from the measuring system, and a second control step of changing pressure or temperature of the measuring system by adjusting the gas amount supplied to/discharged from the measuring system until a gas adsorption amount of the substance to be measured becomes the same as before execution of the first control step.
