Abstract:
This invention relates to a process for reducing the temperature of an effluent stream flowing out of a sterilization chamber. The process involves the use of a mixing tank and heat exchangers which provide for cooling the effluent to a temperature required by local drain or sewer requirements (e.g., below about 60°C) while saving on the amount of cooling water needed to cool the effluent.
Abstract:
A fluid input manifold distributes injected fluid around the body of a bulb to cool the bulb below a threshold. The injected fluid also distributes heat more evenly along the surface of the bulb to reduce thermal stress. The fluid input manifold may comprise one or more airfoils to direct a substantially laminar fluid flow along the surface of the bulb or it may comprise a plurality of fluid injection nozzles oriented to produce a substantially laminar fluid flow. An output portion may be configured to facilitate fluid flow along the surface of the bulb by allowing injected fluid to easily escape after absorbing heat from the bulb or by applying negative pressure to actively draw injected fluid along the surface of the bulb and away.
Abstract:
A process for heating or cooling a liquid (5) by contacting the liquid with an immiscible fluid (1), having different temperature and density, in the presence of a heat transfer enhancing media bed (7) inside a contacting chamber (4). The process including the steps of introducing the liquid into the chamber; contacting the surface film on the media bed with the liquid, whereby the surface film provides for maximum contact and heat exchange between the liquid and fluid; and removing the fluid and the liquid from the chamber.
Abstract:
A supplementary intercooler cools engine air after it has passed through the turbocharger of a vehicle's turbocharged internal combustion engine, but before it enters the engine. The unit has an inlet for capturing the turbo's air charge and an outlet for routing the air charge to the engine after passing through the intercooler. A container stores water until it is needed and a water pump transfers water from the container to the unit. This loosened bond of water is then sprayed on capacitor plates under turbo pressure to be converted into hydrogen and injected into the air intake stream making it a totally "hydrogen-on-demand" intercooler
Abstract:
Le dispositif comporte une enveloppe tubulaire (2) ayant un premier élément de raccordement (5) pour son alimentation en premier fluide à une première extrémité axiale et un second élément de raccordement (6) pour l'évacuation d'un mélange du premier et du second fluides à une seconde extrémité axiale. Un conduit interne de guidage de fluide (18a, 18b) est placé coaxialement à l'enveloppe (2) du mélangeur. Le dispositif comporte de plus un troisième élément de raccordement (7) dans une disposition latérale traversant l'enveloppe (2) entre le premier élément de raccordement (5) et le second élément de raccordement (6) et débouchant dans une chambre cylindrique (3) du mélangeur en vis-à-vis de la surface externe du conduit de guidage (18a, 18b). Le conduit de guidage (18a, 18b) qui peut être en deux parties comporte une paroi dans laquelle est ménagé un espace d'isolation (19a, 19b) qui est mis en communication avec la chambre cylindrique (3). Le dispositif suivant l'invention peut être utilisé en particulier pour assurer le refroidissement d'eau supercritique utilisée dans un procédé d'oxydation d'effluents dans de l'eau supercritique.

Abstract:
Various embodiments of exchangers for tanks, pools, or ponds are described herein. In one embodiment, the exchanger includes an inlet, a central fluid conduit, one or more exchanger extension arms having fluid apertures that direct fluid into a tank at various locations, and one or more supports that support the central fluid conduit and the exchanger extension arms. The fluid apertures may be positioned relatively evenly across the exchanger extension arms and/or the central conduit to direct fluid up or at various directions into the tank. In another embodiment, the exchanger includes a diffuser hub, exchanger extension arms that extend radially outward from the diffuser hub, one or more exchanger rings that intersect with the heat exchanger extension arms, and a fill tube that extends to the diffuser hub. One or both of the heat exchanger arms and/or the exchanger rings include fluid apertures that direct fluid into the pool.
Abstract:
Heat exchange devices and methods of using same are provided. In a general embodiment, the present disclosure provides for heat exchange devices that are cooling devices having a double helical coil in a phase-mixing-cooling section, a helical coil in a phase-separation-cooling section, and a back-pressure valve intermediate the two coils. The cooling devices provide maximum extraction of the heat content from a heated food product using a direct-injected liquid cryogen, and complete separation of the gaseous cryogen phase from the cooled product, while avoiding the formation of a stable foam. Hybrid direct-indirect cooling devices are also provided, as well as methods for using same.
Abstract:
A direct heat exchange method and apparatus for recovering heat from a liquid heat source is disclosed, where the method includes contacting a liquid heat source stream with a multi-component hydrocarbon fluid, where the hydrocarbon fluid compositions has a linear or substantially linear temperature versus enthalpy relationship over the temperature range of the direct heat exchange apparatus.
