Abstract:
A method and apparatus for unloading natural gas (NG), including gasifying liquid and/or compressed NG using the latent heat of water and propane, and/or storing liquid or compressed NG gas in a storage cavern system that utilizes a buffer layer to prevent hydrating the NG gas, the storage cavern system being configured such that the NG may be forced out of a first storage chamber by increasing the amount of brine in a second chamber to displace a buffer fluid located therein such that the displace buffer fluid enters the first storage chamber and displaces the NG, as well as the processes for compressing, chilling and/or liquefying quantities of LNG and transporting those volumes to markets for redelivery.
Abstract:
A vessel for transporting liquefied natural gas is provided. The vessel generally includes a gas transfer system for on-loading and off-loading natural gas to and from the vessel at essentially ambient temperature. The vessel further includes a gas processing facility for selectively providing liquefaction and regasification of the natural gas. The vessel also includes a containment structure for containing the liquefied natural gas during transport. The vessel may be a marine vessel or a barge vessel for transporting LNG over water, or a trailer vessel for transporting LNG overthe-road. A method for transporting LNG is also provided, that provides on-loading of natural gas onto a vessel, condensing the natural gas, storing the gas on the vessel in liquefied form, transporting the gas to an import terminal, vaporizing the gas, and off-loading the gas at the terminal.
Abstract:
A method and device for filling a container with liquid gas from a storage tank includes removing the liquefied gas from the storage tank and feeding it to a container via a liquid feed line through use of a delivery system. The gas is compressed in the container and is removed from the container in its gaseous state and is at least partially liquefied by cooling in a heat exchanger. The at least partially liquefied gas is fed into the liquid feed line at the suction end of the delivery device.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.
Abstract:
Containers suitable for storing pressurized fluids at cryogenic temperatures of −62° C. (−80° F.) and colder are provided and comprise a self-supporting liner and load-bearing composite overwrap, whereby means are provided for substantially preventing failure of the container during temperature changes.
Abstract:
Disclosed is a liquid container adapted to store liquefied natural gas (LNG). The LNG storage container include a sealing wall directly contacting liquid contained in the tank and a structural wall, which is an exterior wall or inner structure integrated with the exterior wall. The container further includes a plurality of connectors mechanically connecting the sealing wall and the structural wall and an intermediate wall structure positioned between the structural wall and the interior wall. The intermediate wall structure is configured to move relative to at least one of the interior wall and the structural wall.

Abstract:
A tubular metal body 1 comprises a tube 2 extruded through a porthole die and composed of a plurality of components 2b joined to one another with a plurality of joint portions 2a extending over the entire length of the tube. The base material metal of the extruded tube 2 in each of the joint portions 2a is subjected to a modifying treatment to produce finely divided crystal grains. The modifying treatment for the extruded tube 2 is conducted preferably by frictionally agitating each joint portion using a probe 8 of a friction agitation joining tool 6. The tubular metal body 1 is available with an increased length in a larger size and has high pressure resistance.

Abstract:
Methods of passivating a metal surface are described, the methods comprising the steps of exposing the metal surface to a silicon-containing passivation material, evacuating the metal surface, exposing the treated surface to a gas composition, having a concentration of reactive gas that is greater than an intended reactive gas concentration of gas to be transported by the metal surface, evacuating the metal surface to remove substantially all of the gas composition to enable maintenance of an increased shelf-life, low concentration reactive gas at an intended concentration, and exposing the metal surface to the reactive gas at the intended reactive gas concentration. Manufactured products, high stability fluids, and methods of making same are also described.
