Abstract:
A device for storing compressed gas having a plurality of storage containers which each have a container wall which surrounds a cavity provided for storing the compressed air. The storage containers are connected to one another, and have at least one connection for introducing and/or discharging the compressed gas. In order to configure the storage containers so that they are as stable as possible, each of the storage containers has a covering layer which is arranged on the container wall at least in partial regions of the particular storage container. In order furthermore to enable the geometrical structure of the device to be adapted individually to the available spaces and to the quantity of gas to be stored, provision is made for each storage container to have a head piece which is connected to the container wall, and for the storage containers to be connected or able to be connected to one another in a modular manner via the respective head pieces. The compressed gas is conducted out of the storage containers via a flow duct which is provided in the head pieces and communicates with the cavity of the respective storage containers via a hole. The individual head pieces are connected via connecting elements which are introduced into corresponding openings in the head pieces.
Abstract:
A method for storing natural gas by adsorption which comprises separating an available natural gas in an infrastructure side (10) into a low carbon number component mainly containing methane and ethane and a high carbon number component mainly containing propane, butane and the like, and storing the low carbon number component by adsorption in a first adsorption tank (16) and storing the high carbon number component by adsorption in a second adsorption tank (18). The method can solve the problem that the high carbon number component condenses within a pore of an adsorbing agent and hence the adsorption of the carbon number component, the main component of natural gas, is inhibited, and thus improves the storage density. Accordingly, the method can be used for ensuring a high storage density also for an available natural gas. An adsorbing agent for use in the method is also disclosed.
Abstract:
A pressure vessel made of plastic consists of an intermediate tubular part closed at each end by an integral end wall. The vessel includes an internally centered tubular part interconnected to said intermediate part by radially extending partition walls. The walls form a plurality of interconnected fluid compartments. The internal walls receive and transmit axial forces operating on the end walls into all walls of the vessel.
Abstract:
A dual-chamber composite pressure vessel includes a first enclosure formed of a fiber reinforced resin matrix, having a hollow cylindrical central section, and first and second oblate end sections formed integrally over respective ends of the central section to define a first chamber. Also included is a second enclosure formed of a fiber-reinforced resin matrix, integrally with the first enclosure, and having a second hollow cylindrical section which is joined at one end to and extends from the second end section co-cylindrically with the central section of the first enclosure. The second enclosure also includes a third oblate end section formed integrally over the other end of the second cylindrical section to define a second chamber.
Abstract:
Current self-contained gas delivery systems that provide gas vapor from a liquefied gas source such as odorized liquid propane consist of a single tank, or container. Both liquid and gas are contained in this tank. Fuel gas is supplied to the user from the vapor phase above the liquid. Boil off from the liquid phase to replace the withdrawn vapor phase results in low initial odorant levels, which increase to very high levels as the liquid is used up. This invention corrects this problem by the addition of a second tank or a second compartment within the first tank. The second tank or compartment, which contains gas phase only, is connected to the first compartment containing the liquefied gas by a small-diameter tube immersed in the liquid phase. The second compartment is positioned or valved in such a way that no liquid will accumulate in the compartment. The gas delivery valve to the gas user is located on the second, or vapor-phase-only container. Under static conditions the pressure in both containers will be equal to the vapor pressure of the liquefied gas. Gas flow to the user from the second compartment reduces gas pressure, resulting in vaporization of sufficient liquid from the connecting tubing to once again equalize system pressure. Because of the small diameter tubing, complete vaporization of the liquid and odorant takes place upon entering the second compartment. Thus, the concentration of the odorant in the gas vapor present in the second or vapor phase compartment is equal to that in the liquid. New systems can be constructed or existing systems can easily be modified to achieve this design.

Abstract:
A small tank or vessel for the containment of pressurized fluids is formed by joining the outer edges of the arms of integral upright and inverted double-Y sections arranged side by side. The arms are part cylinders terminating in the vertical centerline of a cylinder so that a septum between adjacent cylindrical lobes is formed by the vertical legs of the double-Y. A semi-cylindrical shell may be attached to the outer arms of each outside double-Y form.
Abstract:
A cryogenic fuel tank of a cylindrical design having toroidal surface ends, is suspended in aircraft structure through a central front mount member; and the rear of the tank is supported by rod elements which extend: from a mounting ring about the tank, to mount points rearwardly within the interior of the fuselage. The central front mount member has a baffles attached thereto, so as to prevent undue sloshing of the liquid within the tank. The front end of the tank suspension absorbs radial and axial loads, but no bending moments; and the aft linkage suspension arrangement takes primarily radial and torsional loads. Also the aft suspension provides for unrestrained axial and radial contraction and expansion of the outer shell of the tank.
Abstract:
A multi-section tank for offshore liquid storage having an insulated upper receptacle for storage of a liquid at a temperature above or below atmospheric temperature and a lower receptacle filled with fluid, advisably a liquid such as water, oil or the like or a combination of a liquid and a gas. The fluid provided within the lower receptacle functions as a support for the bottom of the upper receptacle thereby eliminating the need for structural supports for the bottom of the upper receptacle when it contains a liquid load. The fluid in the lower receptacle also exerts an internal pressure which counteracts the external compressive sea forces. The lower receptacle is generally kept full enough with a liquid so that the weight of the liquid plus the tank weight enables the tank to withstand horizontal and overturning forces of the sea when the tank rests on a sea floor and the upper receptacle is empty. The upper receptacle is particularly suitable for storing a liquefied gas.
Abstract:
An externally insulated tanker vessel intended especially for the transport of liquid cargoes at temperatures differing from ambient temperature, including a cargo handling system which utilizes a centralized pumping station located aft of the cargo carrying midbody of the vessel and a piping system within the tanks. Towards this end, all of the electrical and mechanical devices, such as the pumps, valves, and safety interlocks, necessary for the safe loading and discharge of the liquefied cargo are centralized at the pumping station. An inert atmosphere is maintained throughout the pump room although provision is made for aeration to facilitate inspection, maintenance and repair. The piping system is mounted such that movement relative to the hull is permitted to reduce any thermally induced stresses.
