A double-walled vacuum-insulated container for holding a cryogenic fluid comprises a support structure for supporting an inner vessel within an outer vessel. The container has an elongated horizontal axis. A conduit extending between the inner and outer vessels has a wall thickness that allows the conduit to carry a substantial portion of axial loads acting on the inner vessel in a direction parallel to the horizontal axis. The support structure further comprises a non-metallic support spanning between the inner and outer vessels, with the non-metallic support capable of transferring substantially all radial loads transverse to said horizontal axis. The non-metallic support is also fixedly attached to the inner and outer vessels so that it is capable of supporting a substantial portion of the axial loads so that the non-metallic support and the conduit cooperate to provide support in the axial direction.

Container for holding a cryogenic fluid

A cryogenic vessel includes a first, outer vessel assembly having an outer vessel and a liquid fill line assembly and a second, ullage space vessel having a bottom and disposed within the first, outer vessel, adjacent to the top of the first, outer vessel. The liquid fill line assembly has a venturi assembly adjacent the bottom of the ullage space vessel. The venturi assembly is structured to create a low pressure zone, relative to the ullage space vessel, during a fill procedure whereby, during a fill procedure, fluid is drawn from within the ullage space vessel into the fill line assembly.

Cryogenic vessel with an ullage space venturi assembly

An economizer circuit assembly for a cryogenic liquid vessel assembly is disclosed. The cryogenic liquid vessel assembly includes a first, outer shell and a second, inner shell defining a storage space. The storage space has a liquid space and a vapor space. The cryogenic vessel also has a delivery line extending from outside the first, outer vessel shell into the liquid space. The economizer circuit assembly includes a vent line and an integration device. The vent line extends from outside the first, outer shell into the cryogenic vessel. The vent line has a first end and a second end. The first end is disposed in the vapor space. The vent line and the delivery line are coupled, and in fluid communication at, the integration device.

Pressure control device for cryogenic liquid vessel

A liquid natural gas filling system structured to store a cryogenic fluid at a low pressure and fill a use vessel at a high pressure. The filling system includes a first, low pressure vessel, at least one second, high pressure vessel, a plurality of conduits, each conduit in the plurality having a valve, extending between, and in fluid communication within the first, low pressure vessel and the at least one second, high pressure vessel, a pressure building means coupled to the at least one second, high pressure vessel and structured to raise the pressure of a cryogenic liquid within the at least one second, high pressure vessel, and an outlet nozzle structured to be coupled to a use vessel, the outlet nozzle coupled via the plurality of conduits to, and in fluid communication with, the first, low pressure vessel and the second, high pressure vessel. The filling system is structured so that a cryogenic liquid may be stored in the first, low pressure vessel at a low pressure. The cryogenic liquid at a low pressure may further be transferred to the at least one second, high pressure vessel via the plurality of conduits. The pressure of the cryogenic liquid at a low pressure in the at least one second, high pressure vessel may be increased to a high pressure by actuating the pressure building means. Thus, the cryogenic liquid at a high pressure in the at least one second, high pressure vessel may be transferred from the at least one second, high pressure vessel to a use vessel via the plurality of conduits and the nozzle.
