Abstract:
A compact storage system for fluids is provided by multitudes of closely spaced parallel planes of adsorptive material (88) that is contained within a substantially impervious barrier layer (2). In normal pressure-containing embodiments, reinforcement (4) is wrapped upon the impervious barrier layer (2) to increase the burst strength of the assembly that results. In higher pressure containing embodiments, material (88) provides reinforcement of barrier layer (2).
Abstract:
An insulated vessel (10, 100, 130) is provided which is adapted to receive a low or high temperature material to be insulated from the environment. The vessel comprises inner and outer membranes (20, 110, 140) and (30, 120, 150) and an outer casing (40, 170). The inner membrane defines an inner cavity for receiving the low or high temperature material and has a first portion which defines an entrance into the inner membrane. The outer membrane encases the inner membrane such that a space is defined between the inner and outer membranes. The outer membrane includes a second portion which is positioned adjacent to the first portion. An insulating material (60, 160) is located in the space between the inner and outer membranes. The inner and outer membranes are joined together so as to seal off the space from the environment. The space is evacuated to less than atmospheric pressure. The outer casing surrounds the outer membrane and has sufficient strength to provide structural and abuse integrity to the vessel.
Abstract:
A compressed gas storage tank comprises a multi-layer sheet metal sandwich structure with a predetermined pattern of solid state diffusion bonds between all the neighburing layers. After the sheets have been solid state diffusion bonded together in the flat condition, the tank is blow formed between dies under superplastic forming conditions to produce at least one superplastically expanded core layer for containing the compressed gas. The configuration of the core layer is determined by the diffusion bond pattern. The expanded core layer provided internal bracing for the tank to give in rigidity and enable it to withstand the high internal pressures.
Abstract:
A vehicle-mounted double-walled ellipsoidal cryogenic storage vessel includes an inner vessel enclosed by an outer shell to form an insulation chamber therebetween. Both the inner vessel and the outer shell are formed in the same manner. An elliptical pressure head of circular cross-section is cut along a diameter to form two end halves. An end wall is secured between the two end halves to form an end, which is secured to an end of a wall like cross-section. This process is repeated with another pressure head to form the other end of the storage vessel. Storage vessels may be constructed of any size desired to allow sufficient ground clearance when mounted under a vehicle.
Abstract:
A carbon dioxide storage and dispensing apparatus and method for storing carbon dioxide which is characterized by a pressure vessel designed to hold carbon dioxide liquid and vapor, which pressure vessel is insulated to control heat input and includes a refrigeration system, fill and withdrawal piping, a fill line mixer provided in the fill line for rapidly mixing incoming liquid carbon dioxide with carbon dioxide in the vapor phase, a volume gauge, heating rod for introducing heat into the vessel and associated operating and safety control devices. The pressure vessel may be characterized by a horizontal or vertical tank and is designed to provide the user with an uninterrupted supply of carbon dioxide gas or liquid, while at the same time overcoming many of the problems associated with currently available carbon dioxide storage and dispensing equipment. A primary feature of the carbon dioxide storage and dispensing apparatus of this invention is the fill line mixer, which facilitates rapid intermixing of the gas phase fluid with the liquid phase introduced into the vessel during filling, in such a manner as to rapidly promote equilibrium conditions and resulting minimum pressure and temperature rise during filling, to eliminate carbon dioxide losses.
Abstract:
A bottle or container includes two semispherical parts which are fixed to each other and are equipped with valves at each end. The bottle can have an inner metal lining and a semispherical membrane which presses against the one part of the lining and has a flange welded between the two parts of the lining. The metal lining with membrane and end pieces forms a replaceable unit. By sampling, the bottle first is filled with a counter pressure medium, for example water, until the membrane lies tightly against one half of the bottle. The bottle is then filled with the fluid/gas-sample such that the membrane reverses as water is pressed out and the sample flows in. The membrane will reverse until it presses against the opposite hemisphere, and the bottle thereby is filled with fluid/gas sample.
Abstract:
A dual gas pressure vessel is divided into a first chamber 22 and a second chamber 24 by collapsible bellows 16. As the gas in the first chamber is dishcarged through an exhaust 29 the bellows collapse until a plate 20 is pierced by a probe 32, following which the gas in the second chamber 24 is vented. A support 26 for the plate 20 ensures that, during charging of the vessel, the first and second chambers are well defined in volume.
Abstract:
A hollow reinforced concrete sphere can be used as a container for transporting compressed gas, such as natural gas. Such containers can be interconnected and towed from one place to another by an ocean-going tugboat. Each container is formed with three band-like groups of reinforcing rings. Each group has its reinforcing rings disposed at right angles to the reinforcing rings in the other groups. The inner and outer surfaces of the container walls can be covered with a desired coating. In constructing the containers, they can be built at the water's edge and then rolled into the water.
Abstract:
The invention relates to a surface tension storage tank comprising a liquid outlet from where the liquid can be expelled under the action of a pressurant gas. A collector device issues into a chamber of a tubular device which also comprises a draining conduit opening at one end at the bottom of said chamber, the other end being situated higher than the first when the tank is being filled. On the side opposite its bottom, the chamber is situated close to the liquid-expelling orifice from which it is separated by an outlet gas barrier. Gas barriers are also provided at the other end of the conduit and on the level of the junction of the collector device with the said chamber.
Abstract:
A liquefied gas tank having thermal insulation in association with a fluidtight body. A liquid supply line terminates at a location within the upper half of said vessel and discharges into a vertical draft-tube which is in fluid communication with the ullage portion of the vessel. The liquefied gas which is supplied into the draft-tube is conditioned to the pressure and temperature within the vessel as it travels downward to the bottom before it can flow radially outward into the tank.
