  • Patent number: 8038129
    Abstract: Circulating air is cooled by heat exchange with adiabatically cooled process air. To this end, a first heat exchanging device is fed with circulating air and the process air. The heat exchanging device contains a humidifying device used to spray water into the process air. In this way, the process air is adiabatically cooled and the corresponding cooling is carried out by heat exchange with the circulating air. Before entering the first heat exchanging device and before leaving same, the process air is guided through a second heat exchanging device in which the cooled process air first extracts heat from the uncooled process air. This increases the cooling performance of the device.

  • Publication number: 20110241232
    Abstract: A cooling tower with a hot water distribution system includes a distribution lateral disposed above a hot water basin. The distribution lateral discharges fluid into the hot water basin, which in turn, releases the fluid through a plurality of orifices. As the fluid is released, it falls on heat-exchanging fill material that assists in increasing the cooling rate of the fluid. The distribution lateral is configured structurally to discharge the fluid through a plurality of outlets at one or more angles (as compared to the horizontal) into the hot water basins. In one embodiment, the outlets are arranged into one or more rows that extend along a substantial length of the distribution lateral. Discharging the fluid in this manner enhances and promotes a more even fluid flow within the hot water basin, which results in a more even fluid flow over and onto the fill material, thereby increasing thermal efficiency.

  • Publication number: 20110210458
    Abstract: The present invention relates to an apparatus and method for the generation of directed vapor from a liquid source. Vaporization takes place within a device capable of confining boiling to a geometrically small volume, and expelling it as heated vapor via capillary vaporization. The foregoing is accomplished through the use of a lightweight, compact and portable personal vaporization device that generates heated vapor by the flash boiling of small volumes of aqueous liquid in a safe and energy-efficient manner. Further, the production of vapor absent microbes in aqueous systems is accomplished through the combination of microporous componentry and flash vaporization. The apparatus and methods are directed toward personal humidification for comfort and therapeutic purposes in the case of aqueous liquids, but may also be used with other, non-aqueous liquids.

  • Publication number: 20110196159
    Abstract: A system for mixing ortho-xylene with an oxygen-containing gas such as air comprises an evaporator vessel fed with the gas and having a lance projecting into the gas. The lance is provided with a metal spray nozzle for injecting droplets of hot liquid ortho-xylene into the gas stream, concurrently with the direction of flow of the gas. The metal at the surface of the spray nozzle, that in use is in contact with the liquid ortho-xylene, has a high surface hardness to resist erosion, particularly by cavitation. The system is useful in the production of phthalic anhydride by the oxidation of ortho-xylene with air, whereby the risk for deflagrations is reduced. A soft metal seal is the preferred gasket between the spray nozzle and the lance.
