Abstract:
Systems and methods for storing energy in gaseous form in submerged thin-wailed tanks (1, 7, 61, 82, 63, 67, 101) are secured to the ocean or lake floor but are open to the water at the tank bottoms (1a, 64) and are configured to be filled with gas while submerged. A conduit (2, 2a, 11) operatively connected to the tanks (1, 7, 61, 62, 63, 67, 101) provides flow from a surface source of an energy-containing gas to the tank interiors (1d, 101 a). Surface or subsurface pumping apparatus (3, 37, 42, 46, 48, 53) which may include piston-less pressure cylinders (37) or have leveraged pistons (48, 53) provide a preselected flow rate of the energy-containing gas into the tank interiors (1d, 101 a) against a back pressure essentially equal to the static pressure of the body of water at the location of the tank (1, 7, 61, 62, 63, 67, 101) to displace an equivalent volume of water through the open bottom (1 a, 64). The conduit (2, 2a, 11) can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank (1, 7, 61, 62, 63, 67, 101) using Aluminum activated with Galinstan.
Abstract:
The invention relates to a device for storing and releasing fluids at a near-constant pressure, said fluids including a gas and a liquid, which includes a set of substantially identical tanks (1), said tanks including: a portion (G) containing the gas and a portion (L) containing the liquid; a means (23) for separating the gas and the liquid in the tank (1); a gas inlet (36) and outlet (36); and a liquid inlet (35) and outlet (35). The tanks (1) have an outer cylindrical shell (100) consisting of at least one metal tube (101) of the type used for gas and oil pipelines, having an outer diameter larger than 32" (813 mm), and a ratio of the length to the outer diameter thereof that is greater than 8.
Abstract:
An apparatus for forming a polymeric pressure vessel has an outer tube extruder for driving a fluid polymeric material and forming the fluid polymeric material into an outer tubular member; a variable die located downstream of the outer tube extruder and constructed and arranged to alternately increase and decrease in size to thereby alternately increase and decrease the thickness of the wall of the outer tubular member; and a molding apparatus located downstream of the variable die and constructed and arranged to expand spaced-apart portions of the outer tubular member having greater wall thickness into hollow chambers to thereby form a plurality of serially interconnected hollow chambers.
Abstract:
A container is provided for storing pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 DEG C (-190 DEG F) to about -62 DEG C (-80 DEG F). The container is constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 DEG C (-100 DEG F).
Abstract:
A walking assistance device, for example, a walking cane, a walking crutch, or walker includes a gas storage vessel for providing an ambulatory supply of medicinal gas for a user of the device. The gas storage vessel is formed from a plurality of polymeric hollow chamber having either an ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The gas storage vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The container system further includes a fluid transfer control system attached to the gas storage vessel for controlling fluid flow into and out of the gas storage vessel and a gas delivery mechanism for delivering gas from the gas storage vessel to a user in a breathable manner.
Abstract:
A pipe (10) in a cargo pressure tank of a ship (2), the pipe (10) mainly being used for loading and unloading of fluids, and the open end portion (13) of the pipe (10) being placed immediately above the lower bottom section (14) of the cargo pressure tank (1).
Abstract:
A container (10) for holding a supply of compressed fluid such as carbon dioxide has a length of tube (12) formed into a multi turn helical coil (14). A first valve (16) is provided at the lowest end (18) of the coil (14) for controlling the flow of fluid out of the container (10). A thermal insulating setable foam (20) envelopes the tube (12) and coil (14), though not the valve (16) which is disposed outside of the foam (20). A strap (26) extends about the coil (14) to bind the turns of the coil (14) together for added safety and strength. Coil (14), and setable foam (20) are disposed within a heat insulating housing (28). Inlet valve (22) is attached to an upper end of the tube (12) proximate the highest one of the turns of the coil (14).
