    摘要: LNG is pumped to high pressure, vaporized, further heated and then expanded to create rotary power that is used to generate electrical power. A reservoir of carbon dioxide at about its triple point is created in an insulated vessel to store energy in the form of refrigeration recovered from the evaporated LNG. During peak electrical power periods, liquid carbon dioxide is withdrawn therefrom, pumped to a high pressure, vaporized, further heated, and expanded to create rotary power which generates additional electrical power. The exhaust from a fuel-fired combustion turbine, connected to an electrical power generator, heats the high pressure carbon dioxide vapor. The discharge stream from the CO.sub.2 expander is cooled and at least partially returned to the vessel where vapor condenses by melting stored solid carbon dioxide. During off-peak periods, CO.sub.2 vapor is withdrawn from the reservoir and condensed to liquid by vaporizing LNG, so that use is always efficiently made of the available refrigeration from the vaporizing LNG, and valuable peak electrical power is available when needed by using the stored energy in the CO.sub.2 reservoir.

    摘要: A method and system for delivering high pressure, subcooled liquid carbon dioxide. An insulated tank having a height greater than its internal diameter holds liquid CO.sub.2 to a depth of at least about 6 feet, and high pressure, subcooled liquid CO.sub.2 is delivered from a lower outlet of the tank. CO.sub.2 vapor is condensed in the upper region to maintain a desired high pressure, e.g., about 290-310 psi., at the top of the tank. By withdrawing liquid CO.sub.2 from an upper region in the tank, subcooling it by heat exchange and returning subcooled liquid CO.sub.2 to a lower region, a thermocline region is created at least 2 feet below the surface, and above which equilibrium high pressure liquid CO.sub.2 exists. Heat exchange is efficiently carried out during off hours using liquid carbon dioxide to chill the condensed refrigerant from an existing auxiliary mechanical refrigeration unit.

    摘要: A high pressure pump and delivery system mating to LNG storage and suited for natural gas powered trucks and buses, but also suitable for other cryogenic liquid fuels. The reciprocating pump is comprised of a liquid pumping portion and a vapor compressing portion, operating in concert so that it is possible to locate the pump above a source of saturated LNG and to reliably supply high pressure LNG. The delivery system provides a method of utilizing both the pumped LNG and the compressed NG in a Diesel type fuel injection system, and also to scavenge NG vapor from the LNG storage container so as to extend it's storage life. While especially useful for trucks and buses, the present invention is not limited thereto, as it is also useful for locomotives, automobiles and other vehicles designed to operate through combustion of natural gas, as well as stationary applications.

    摘要: A liquid CO.sub.2 storage vessel system for user sites, which receives warm CO.sub.2 and then cools the liquid CO.sub.2 to temperatures below -25.degree. F. before further use. The cooled liquid CO.sub.2 can be at temperatures and pressures of near equilibrium conditions or at sub-cooled conditions. Cooling of the liquid CO.sub.2 is conducted by CO.sub.2 vapor removal from liquid CO.sub.2 ; and is independent from the CO.sub.2 use, so cooling can be conducted during both normal and off hours. The storage vessel can be safely filled from most existing delivery vehicles, and the previously cooled liquid CO.sub.2 in the bottom of the storage vessel can be prevented from mixing with the warmer being-delivered liquid CO.sub.2, so the temperature of the liquid CO.sub.2 immediately going to use is little effected by the delivery being conducted.

    摘要: A refrigerated transport having an insulated enclosure and including a cryogen reservoir, e.g., high-pressure liquid cryogen or solid CO.sub.2. A plurality of thermosyphons associated with the walls and floor of the enclosure adjacent the interior skin intercept heat attempting to enter the enclosure. An intermediate heat sink draws the intercepted heat from the upper portions of the thermosyphons. The temperature of the heat sink is thermostatically controlled in a manner that the rate at which heat from the heat sink is absorbed by the cryogen is regulated to maintain the heat sink within a desired temperature range such that the thermosyphons will in turn maintain the enclosure and its product load at the desired subambient storage temperature.

    摘要: Filling units for filling small tanks or the like with gasoline, kerosene, or other flowable materials which attach an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, removal of the displacer section from the tank, as by sliding a section of the overall unit upward, allows the liquid in the funnel to enter the tank and fill the volume evacuated by the displacer section to complete the filling without any spillage. The overall unit may be removed from the tank each filling operation, or it may be designed to include a protective cap that fits over the upward-protruding portion of the unit, allowing the unit to remain mounted on the tank.

    摘要: A system for storing electrical energy in the form of triple-point CO.sub.2 and then using such stored energy plus heat to generate electrical power. A reservoir of carbon dioxide liquid at about the triple point is created in an insulated vessel. Liquid carbon dioxide is withdrawn and pumped to a high pressure, which high pressure carbon dioxide is heated and expanded to create rotary power which generates electrical power. The discharge stream from the expander is cooled and returned to the vessel where carbon dioxide vapor is condensed by melting solid carbon dioxide. A fuel-fired gas turbine connected to an electrical power generator can be used to heat the high pressure carbon dioxide, and an ambient air stream flowing toward the gas turbine can be cooled by giving up heat to the high pressure carbon dioxide stream. The returning expanded carbon dioxide stream can be returned to a separate auxiliary vessel, and liquid carbon dioxide pumped from such auxiliary vessel to a main vessel wherein solid carbon dioxide is formed and then transferred to the auxiliary vessel.

    摘要: Useful heat from an ice-maker is efficiently recovered and employed to heat water without any significant increase in the energy normally expanded in making ice. During ice-making, liquid refrigerant from a high-pressure receiver is expanded and supplied to an evaporator where ice-making occurs. Expanded refrigerant is returned to a compressor through an accumulator, and high-pressure vapor is condensed by heat-exchange with a circulating stream of water withdrawn from a storage tank. Condensed refrigerant is returned to the receiver through a restrictor. During the harvesting cycle, relatively warm, high pressure vapor from the receiver is fed to the evaporator, and any of it condensed to liquid therein is trapped in the accumulator. The compressor runs continuously throughout harvesting and ice-making, and any refrigerant trapped in the accumulator is used to subcool the high-pressure liquid prior to its expansion in the subsequent ice-making cycle.

    摘要: A cabinet cooler or freezer which efficiently utilizes cryogenic refrigeration either with or without mechanical refrigeration. The freezer intermittently freezes relatively large batches of food by efficiently utilizing the natural expansion effect of a liquid cryogen, in combination with mechanical circulation by blowers, to create an overall circulation that efficiently removes heat from the food. A secondary circulation effect is induced, in a manner similar to the operation of a jet pump, which amplifies the circulation and allows CO.sub.2 to be employed with modulating valve control to achieve uniformly low temperature throughout the cabinet without snow build-up on the cabinet bottom. Some cabinet versions create a cyclonic circulation pattern about a vertical axis that is particularly effective.
