The hydrogen storage device of the invention is provided with a thermally insulated container having an inner space, a liquid hydrogen inflow opening, and a hydrogen gas outflow opening, and a hydrogen adsorbing member filled in the inner space.
Abstract:
A cylindrical structure includes a vertical wall (3) and a bottom wall (2), the bottom wall having a plurality of sectors (4) which are rotated images of each other, each sector including a plurality of adjacent rectangular elements (8), characterized by the fact that the bottom wall has the shape of a regular polygon whereof each side (6) corresponds to one of the sectors, the edges of the rectangular elements of one sector being respectively perpendicular and parallel to the side of the polygon corresponding to the sector.
Abstract:
Disclosed is a floating marine apparatus including a liquefied natural gas (LNG) tank. The apparatus includes a first LNG containing compartment and a second LNG containing compartment next to the first compartment. The apparatus further includes a bottom passage interconnecting bottom portions of the first and second compartments for fluid communication therebetween.
Abstract:
Disclosed is a liquefied natural gas storage apparatus. The apparatus includes a heat insulated tank and liquefied natural gas contained in the tank. The tank has heat insulation sufficient to maintain liquefied natural gas therein such that most of the liquefied natural gas stays in liquid. The contained liquefied natural gas has a vapor pressure from about 0.3 bar to about 2 bar. The apparatus further includes a safety valve configured to release a part of liquefied natural gas contained in the tank when a vapor pressure of liquefied natural gas within the tank becomes higher than a cut off pressure. The cut off pressure is from about 0.3 bar to about 2 bar.
Abstract:
The present invention comprises a tank for liquefied gases or a so-called cryogenic tank (1) with a tank bottom structure (10) and a tank wall structure (11) arranged around a circumference of the tank bottom structure (10). The tank bottom structure (10) is provided with a tank bottom hub (2) adapted for being held by a bottom hub retainer (20) on a tank support structural floor (23). The tank is simple to install, cheap in production and handles in an improved manner forces acting upon it.
Abstract:
The invention regards a tank for storing of fluid at low temperature of insulated self carrying plate structure, where the plates comprises a sandwich structure, comprising two surface sheets of a metal or a material with similar properties and a core material with properties allowing for the variation of thermal deformation between the inner and outer surface sheets, which core material also provides for at least partly the insulation of the tank and which provides at least partly the necessary stiffness and strength of the wall. The invention also regard support means for the tank, a sandwich structure for use in a tank, and a method for producing the tank.
Abstract:
A container for cryogenic fuels assembled from a plurality of identical straight and closed profiles which are arranged in different configuration from one another and are straight hollow profiles which are arranged parallel to one another and of which at least one outer boundary wall maintains a functional distance from an outer boundary wall of an adjacent profile and to the open ends of which a common cap as a common connection space of the profiles is in each case contiguous on both sides.
Abstract:
A storage tank containment system including a cubic-shaped tank having an outer shell having cylindrical walls and an internal cross brace interconnecting the cylindrical walls for the efficient storage and transportation of large quantities of fluid, for example, liquid natural gas.
Abstract:
Methods and systems for transportation of a cryogenic fluid. The system includes a floating liquefaction unit receiving a gas from a source, a shuttle vessel for carrying liquefied gas away from the liquefaction unit, and a floating regasification unit for receiving the liquefied gas from the vessel, regassifying the liquefied gas and providing the gas to a distribution system.
Abstract:
A method of manufacturing a tank suitable for storing very cold cryogenic liquids, such as liquefied ethylene (LEG) or natural gas (LNG) or a corresponding medium, the basic form of the tank corresponding to a rectangular prism and being manufactured from aluminium or the like material. The tank is produced at least mainly from prefabricated construction elements of few different types so that plane elements to be used as shell panels of the tank, the elements being produced by mechanically extruding aluminium profile elements or the like, are produced, the elements including a plane part and a stiffening part and which are welded by their plane parts to each other using friction welding. The plane elements produced thus are provided with longitudinal and/or transverse stiffeners being produced by mechanically extruding aluminium profile elements or the like, which are welded to each other by using friction welding. The plane elements having stiffeners produced thus are attached to each other and/or to separately produced edge and/or corner elements into self-supporting volume units having at least four sides.
