Abstract:
Methods and systems for modular fuel storage and transportation are provided. In an embodiment, a fuel storage system includes one or more fuel containers each supported by a fuel container support assembly. The fuel storage system may be mounted to a transportation device such as a vehicle or used in a stand-alone fashion. Each support assembly may include a plurality of detachable end support members such as end support members configured to support the end portions of the fuel container and side support members configured to support the body portion of the fuel container. Some of the end support members may include neck grooves such that when the end support members are coupled, the neck grooves form an enclosure around the neck portion of the fuel container. In an embodiment, the support assembly is configured to facilitate release of excess pressure in the fuel container.
Abstract:
An apparatus and method estimate fluid mass in a cryogenic tank that holds a multiphase fluid comprising a liquid and a vapor. The apparatus comprises a level sensor, a pressure sensor and a computer. The level sensor provides a parameter representative of a level of the liquid. The pressure sensor provides a pressure signal representative of vapor pressure inside the cryogenic tank. The computer is operatively connected with the level sensor and the pressure sensor to receive the parameter and the pressure signal, and is programmed to determine the level from inputs comprising the parameter, to calculate a first volume of the liquid from inputs comprising the level, and to calculate a first mass of the liquid from inputs comprising the first volume and the pressure signal.
Abstract:
The invention relates to a tank container (100; 100′) for the transport and storage of cryogenic liquefied gas, comprising a framework (120) and a cylindrical vessel (110) connected to the framework (120), wherein the vessel (110) is covered by a superinsulation arrangement (130) based on an aerogel composition, and the vessel (110) is connected to the framework (120) by a clamping device (30) which is adapted to allow for a relative movement between the framework (120) and the vessel (110) due to thermal expansion or contraction of the vessel (110).
Abstract:
A system and method enable intelligent refuelling of a pressurised vessel. The method includes receiving a gas at a refuelling port, wherein the refuelling port is coupled to the pressure vessel; determining a temperature 5 of the pressure vessel; determining a pressure of the pressure vessel; directing the gas through a nozzle, wherein the pressure vessel and nozzle are thermally coupled such that Joule-Thomson expansion of a gas flowing through the nozzle cools an interior cavity of the pressure vessel; and controlling a shut-off valve according to an amount of gas in the pressure 10 vessel determined according to the temperature and pressure, wherein the shut-off valve is located between the refuelling port and the pressure vessel, for controlling a flow of gas between the refuelling port and the pressure vessel.
Abstract:
According to one embodiment, a liquid dispensing system includes a pressure chamber comprising a liquid space and a vapor space, and a liquid dispenser. A first and second orifice located in a bottom portion wall of the pressure chamber and each coupled to a vapor conduit extending into the vapor space of the pressure chamber form passageways between the first and second orifice and the vapor space. A third orifice of equal to or greater than approximately two inches diameter is located in the bottom portion wall of the pressure chamber. The third orifice is coupled to a liquid supply inlet port of the liquid dispenser; the second orifice is coupled to a liquid bypass port of the liquid supply pipe; and the first orifice is coupled to a vapor release port of the liquid dispenser.
Abstract:
A lightweight intermodal or road trailer based system for transporting refrigerated gaseous fluids is provided. The system includes an enclosed and insulated transportation housing, and a plurality of low-temperature resistant type 4 pressure vessels. The pressure vessels are at least three feet in diameter secured within the transportation housing for containing the gaseous fluids.
Abstract:
A method and system for installing and maintaining submerged cryogenic pumps is disclosed. The submerged pump may be positioned within a product storage vessel. Alternatively the submerged pump may be positioned within a product storage vessel with a sump that is integral with and not removable from the vessel. The pump may used for the movement of products, such as cryogenic liquids, including but not limited to, nitrogen, argon, ethylene, natural gas, nitrous-oxide, carbon-monoxide, hydrogen, helium, and carbon-dioxide. Superior results are obtained with respect to access, maintenance and handling of the pump within a product storing vessel.
Abstract:
A horizontal type cylindrical double-shell tank includes an inner shell and an outer shell. The inner shell includes an inner shell main part storing a liquefied gas and an inner shell dome protruding from the inner shell main part. The outer shell forms a vacuum space between the inner shell and the outer shell, and includes an outer shell main part surrounding the inner shell main part and an outer shell dome surrounding the inner shell dome. The inner shell dome is provided with an inner shell manhole. The outer shell dome is provided with an outer shell manhole at a position corresponding to a position of the inner shell manhole.
Abstract:
A support structure of a ship tank includes: a curved surface facing an outer peripheral surface of a horizontal type cylindrical tank; and a pair of support units supporting the tank on the curved surface. Each of the support units includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank; a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the tank side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at an opposite side to the tank. The inner members are fixed to the tank. The outer members of one of the support units are configured such that displacement of the outer members in an axial direction of the tank relative to the curved surface is restricted. The outer members of the other one of the support units are configured to be slidable on the curved surface in the axial direction of the tank.
Abstract:
