A process for collection, storage and transport of boil off-gas from a liquefied natural gas storage tank. An ultra-low temperature, composite gas tank is provided to accept the boil-off gas and saturated vapor at ultra-low-temperatures in a range of about −80° C. to −45° C. (about −112° F. to −229° F.) and at high pressure of about 150 bar (about 2,175.5 psi). Boil off gas collected from liquefied natural gas storage at a pressure in a range of about 15 to 18 bar (217.5 psi to 261 psi) and at a temperature in of about −150° C. (about −238° F.). The ultra-low temperature, composite gas tank can hold the gas as it warms to ambient temperature. The process includes a liner step; a filament step; a wrap step; and a filling step. Optional steps include an insulation step; a fiber step; a layering step; a nozzle step; and a gas step.

The present invention provides a complex power generation facility including a first transfer unit that transfers liquefied natural gas; a first heat exchange apparatus that causes the liquefied natural gas supplied from the first transfer unit to exchange heat with seawater, vaporizes the liquefied natural gas into natural gas, heats the seawater into hot water, and discharges the hot water; a second heat exchange apparatus that selectively receives the hot water discharged from the first heat exchange apparatus and caused the natural gas passing through the first heat exchange apparatus to exchange heat with seawater and hot water; and a power generation unit that generates power as the natural gas supplied from the second heat exchange apparatus passes therethrough.

A tank for pressurized gas, such as hydrogen, comprises a structure defining a volume of the tank and having at least one opening. There are as many bases as there are openings, with each base being disposed in one of the openings. A sealing enclosure covers an entire internal surface of the structure and interfaces with the base. At least one conduit allows leakage between an outer surface of the sealing enclosure and an outside of the tank. The base has a recessed external profile with an undercut at an interface with the structure. The at least one conduit comprises at least one chute interposed between the structure and the base.

Disclosed is a method for gauging the liquid propellant tank of a spacecraft during a phase of high-thrust along an axis, the tank being thermally conductive and having a known geometry. The method includes steps of: attaching, on a wall of the tank, a heating member and at least one temperature sensor in proximity to the heating member and in a plane of interest perpendicular to the thrust axis; during the high-thrust phase, heating the wall of the tank and acquiring temperature measurements of the wall of the tank at rapid frequency; determining the instant I when the temperature measured by the sensor changes, such change indicating the presence of the liquid-gas interface in the tank in the plane of interest; and determining the volume of liquid propellant present in the tank at instant I.

A feedthrough for use with a pressure vessel is presented. In some embodiments, the feedthrough is formed with an insulator portion with insulator threads that mate with threads of a body portion. In some embodiments, the threads can be rounded or square threads. In some embodiments, the insulator portion includes a through hole and a fill structure. The fill structure can include a fill-tube that can be used to communicate with the pressure vessel where the body portion is attached. In some embodiments, the insulator portion can include additional through-holes to receive one or more conductors.
