The present invention relates to a method and system for storing cold fluid. The system includes a main tank and an auxiliary tank that are in fluid communication, and the auxiliary tank receives vapor and expanding fluid as the cold fluid in the main tank warms thereby avoiding overpressurization of the system.

Method and system for storing cold liquid

A method and apparatus for limiting the level of cold liquid within a vessel by sensing the expansion of cold liquid due to ambient heat leak, and venting pressurized vapor from the vessel to reduce the rate of expansion of the cold liquid.

Apparatus for, and a method of, withdrawing liquefied natural gas stored in a primary insulated storage tank at a low pressure and at a temperature close to its boiling point; increasing the pressure of the withdrawn liquefied natural gas and then feeding the pressurized liquefied natural gas through a heat exchanger to warm the liquefied natural gas to a subcooled or near saturated liquid condition at a temperature of about -220.degree. F. to -126.degree. F. when at a pressure of about 50 psig to 550 psig; and feeding the said warmed and pressurized liquefied natural gas to an insulated tank on a vehicle at a refueling facility, said vehicle using liquefied natural gas as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the said liquefied natural gas in liquid form, at an approximate saturated condition at a temperature of about -220.degree. F. to -126.degree. F. and a pressure of about 50 psig to 550 psig.

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 Liquid carbon dioxide is withdrawn and pumped to a high pressure, which high pressure carbon dioxide is heated and expanded to create rotary power which generates electrical power.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.

A storage tank for liquids is provided with a vertically movable horizontal deck which separates a liquid above the deck from a liquid below the deck. The deck and tank have line and pulley mechanisms to prevent the deck from skewing or tilting during vertical displacement. The liquid above the deck can be the same or different than the liquid below the deck but generally they have different densities so that the deck can float at the interface between the liquids.

A portable, compact, gas-fired cooking and barbecuing device for frying and boiling food in conventional cooking utensils, or barbecuing food when a barbecuing attachment is utilized. The device includes a bowl-shaped body having a bottom and a relatively deep, cylindrical side wall. A gas burner assembly is mounted in the bowl-shaped body so that the annular burner of the assembly is positioned toward the bottom of the body to protect it from wind effects. Three circumferentially spaced, radially extending support members connect the burner to the cylindrical side wall of the bowl and serve as supports for cooking utensils in which food is to be fried or boiled. Mounting portions on the other ends of the support members extend above the upper edge of the body for supporting large sized cooking utensils. When the lower cylindrical portion of an annular barbecuing attachment is engaged with the support members of the burner assembly, food items may be barbecued on the barbecuing grill of the attachment. The diameter of the upper portion of the attachment is larger than the side wall of the bowl-shaped body to prevent food drippings from falling onto the bowl side wall.

Condensing exhaust steam by conveying a stream of the exhaust steam under vacuum to a base cooling tower to condense the steam so long as the heat rejection capacity of the base cooling tower is adequate to condense the steam; supplementing the base cooling tower, when it provides inadequate cooling, by contemporaneously also withdrawing cold cooling water from a cold water reservoir and injecting the cooling water into the stream of exhaust steam under vacuum to condense a portion of the steam to water such that the remaining portion of the steam is condensed to water in the base cooling tower; withdrawing hot condensed water from the exhaust steam stream and feeding a portion thereof to a hot reservoir; withdrawing hot cooling water from the hot reservoir, when the cooling tower capacity is adequate to decrease the temperature of the exhaust steam to below the temperature of the hot cooling water in the hot reservoir, and subjecting the withdrawn hot cooling water to the exhaust steam vacuum to cool the hot cooling water by converting part of the water to steam; and feeding the so-cooled cooling water to the cold water reservoir.

Apparatus and method for condensing steam

Refrigeration is produced by compressing a multi-component refrigerant to a high pressure, cooling the high pressure refrigerant to produce a refrigerant having a vapor phase and a liquid phase, separating the two phase refrigerant into a vapor phase and a liquid phase, passing the refrigerant vapor phase through heat exchanger means to cool and condense it to a liquid, expanding the so-formed cold stream of condensed liquid to a colder low pressure stream, passing it back through the heat exchanger means to provide low temperature refrigeration thereto to cool the high pressure vapor stream fed therethrough and have extra refrigeration for removing heat from a product, and expanding the separated high pressure liquid phase to a low pressure cool stream, feeding the low pressure cool stream to an intermediate point in the heat exchanger means, combining said stream with the cold low pressure stream formed from the vapor removed from the vessel to provide warm temperature refrigeration to remove heat from the high pressure vapor stream fed therethrough, and compressing the combined refrigerant to repeat the process, said process developing extra refrigeration for removal of heat from a product.
