    摘要： The present invention relates to an improved heat transfer device and process, such as the heat exchanger included in a process for vaporizing cryogenic fluids industrial gas supply systems. The system having a water bath and heat exchange tube bundle disposed therein operating to vaporize and superheat industrial liquefied gases including fuel gases. Water contained in a tank transfers heat to the bundle by natural convection without benefit of forced water circulation. The water is heated by means such as steam, combustion processes or electric heat and a heat exchange tube bundle submerged within the water tank is used to vaporize and superheat liquefied gas, which passes within the tubular elements of the heat exchange bundle. Gas bubble agitation is provided by discharging nitrogen, air or other non-condensing gas into the water via a gas-sparging manifold located below the tube bundle for the purpose of increasing the rate of heat exchange from the heated water to the cooler liquefied gas and increasing the useable energy storage capacity of the water during operation when the heating means is shut off.

    摘要： A process and corresponding apparatus for regasifying a cryogenic liquid to gaseous form includes a process step and suitable structure to transfer heat from ambient air to the cryogenic liquid across a heat transfer surface by circulating the cryogenic liquid or an intermediate fluid through an atmospheric vaporizer, where the ambient air and the cryogenic fluid or intermediate fluid are not in direct contact; and a process step and suitable structure to mechanically scrape an external portion of the heat transfer surface exposed to the atmosphere to remove frost from the external portion of the heat transfer surface, where defrosting is achieved without the need to discontinue circulating the cryogenic fluid or the intermediate fluid through the atmospheric vaporizer.

    摘要： Liquefied hydrocarbon gas carried by a tanker (78) is transferred to an import terminal (10) where the liquefied gas is heated to vaporize it and to heat the cold gas to at least −30° C. but preferably about 0° C., with the warmed gas transferred to a gas receiving facility (20, 83). Vaporizing and heating is accomplished by using a large number (more than 10) of vertically mounted air vaporizers (84) of a known type, which use environmental air that flows down the exterior of the finned tubes in which the liquefied or cold gas flows. In the present invention a large number of individual vaporizers are positioned in close proximity to each other, i.e. within a distance that is smaller than half the vertical height of the vaporizer tubes. Their close proximity allows many units to be installed on a small plot space, and also affects their thermal performance.
