Abstract:
A cylindrical shell for a tank of a railway tank car is made using roll-forming technology and straight longitudinal weld seams. The cylindrical shell has a longitudinal axis and a uniform cross-sectional shape in a plane normal to the longitudinal axis. The cylindrical shell includes a plurality of elongated segments welded together along weld seams extending parallel to the longitudinal axis of the cylindrical shell. Each elongated segment forms a portion of the cross-sectional shape of the shell and is formed by passing a flat piece of metal plate stock material through a roll-forming machine configured to progressively bend the piece of stock material. In one embodiment, exactly three identical elongated segments, each defining an arc of 120 degrees, are welded together along adjacent longitudinal edges to form a cylindrical shell having a circular cross-section.
Abstract:
An apparatus or system is provided for withdrawing a cryogenic liquid from a container. The liquid may be drawn from the container independent of the orientation of the container. The apparatus includes a conduit having a flexible metallic hose portion and a metallic head. The flexible hose portion has a first end in fluid communication with an outlet portal of the container and a second end to which the head is attached.
Abstract:
Disclosed is a container for storing, transporting, and dissociating hydrate pellets, the container comprising: a first container (100) made up of a plurality of frames; a second container (200) which is rotatably installed inside the first container (100), stores hydrate pellets therein, and has an internal surface to which a heat insulating member is attached; and a refrigerating machine (300) which is installed inside the first container (100) and refrigerates the second container (200), wherein the second container (200) is equipped with a heating wire (210), which is heated to dissociate the hydrate pellets by being supplied with power, or with a hot water tube (220), through which hot water flows to dissociate the hydrate pellets, on the internal surface thereof.
Abstract:
This disclosure provides systems, methods and apparatus for delivery of gas from solid phase sources. A solid phase gas source canister can include multiple separated volumes configured to contain multiple quantities of a solid phase gas source. Sublimated vapor can be independently produced by each quantity of the solid phase gas source. In some implementations, the solid phase gas source canisters are configured for simultaneous fill of the multiple volumes with a solid source gas phase powder.
Abstract:
The present invention relates to a vehicle (2) having a drive (4) for a combustible gas, in particular hydrogen, and a plurality of storage vessels (6) for a combustible gas which are connected to the gas drive (4) via a connector. In order to provide a simple possibility of determining at least approximately accurately the still present residual quantity of a combustible gas which is available for the operation of the vehicle, it is proposed that a plurality of storage vessels (6) are connected to the vehicle (2), wherein each storage vessel (6) has a connection piece (8), by way of which it can be connected to the vehicle-side connector (10) mechanically and in a pressure-resistant manner, and the vehicle (2) has an electronic controller (16), by which the number of storage vessels (6) which are connected to the vehicle (2) and the presence of combustible gas in the respective storage vessels (6) can be determined via sensors, and the electronic controller (16) transmits a quantity signal about the gas quantity which is still available from the storage vessels (6) to a supply display (18) which is present in the vehicle (2), wherein the magnitude of the quantity signal is dependent on the number of storage vessels (6) which have been detected as being connected to the vehicle (2) and filled.
Abstract:
A mounting system for a pressure vessel is disclosed. The mounting system includes a first retention cap, a second retention cap, and a plurality of fastening bands coupled to the first retention cap and the second retention cap, wherein the first retention cap and the second retention cap each include a concave inner surface and a mount, the concave inner surface substantially corresponding to at least a portion of an exterior surface of the pressure vessel to secure the pressure vessel between the first retention cap and the second retention cap.
Abstract:
A compressed natural gas fueling system includes a frame arrangement with at least one tank disposed therein and an inlet that can receive a compressed natural gas fueling nozzle to fill the at least one tank. The fueling system can be attached with and supported by frame rails behind a cabin of a vehicle such that the inlet is positioned above the frame rails.
Abstract:
A cryogenic storage tank comprises a partition that divides a cryogen space into a main storage space and an auxiliary space. A valve disposed inside the cryogen space is associated with a first fluid passage through the partition. The valve comprises a valve member that is actuatable by fluid forces within the cryogen space. A second fluid passage through the partition comprises a restricted flow area that is dimensioned to have a cross-sectional flow area that is smaller than that of a fill conduit such that there is a detectable increase in back-pressure when the main storage space is filled with liquefied gas.
Abstract:
In various embodiments, lined underground reservoirs and/or insulated pipeline vessels are utilized for storage of compressed fluid in conjunction with energy storage and recovery systems.
Abstract:
Described herein are systems and methods for cryogenic fluid delivery. The systems may include a pressure vessel containing a cryogenic fluid formed of liquid and vapor that is connected to a use device via a withdrawal line. The withdrawal line connects to the cryogenic fluid in the pressure vessel via two routes, a liquid tube and a vapor line. The vapor line may include a back-pressure regulator that opens the vapor line depending on pressure in the system. The withdrawal line may include a pressure relief valve that exerts pressure on the liquid tube. A bypass line may connect the withdrawal line to the liquid tube. The bypass line has a check valve that permits free flow of cryogen from the withdrawal line to the liquid tube via the bypass line while prohibiting cryogen flow from the pressure vessel through the bypass line. The methods employ the systems described herein.
