Abstract:
The cryogenic storage vessel comprises a liquid storage volume, a conduit leading from that volume, a large flowable mass of solid spherical insulators within that conduit and a diaphragm at the end of the conduit opposite the liquid storage volume. The ambient pressure of the seawater surrounding the apparatus is transmitted to the cryogenic liquid by means of displacement of the diaphragm which is in contact with the ambient seawater and the corresponding change in the internal volume of the liquid storage apparatus. The mass of insulating spheres are allowed to flow within the conduit and partially into the liquid storage area upon displacement of the diaphragm. The insulators allow vapor of the liquid within their interstices but maintain a thermal gradient between the liquid and the diaphragm sufficient to protect the diaphragm from the extremely low temperatures of the cryogenic liquid by substantially preventing convection and conduction.
Abstract:
Apparatus and method for ''''peak shaving'''' storage of gas in a gas distribution system wherein the pressure varies from a maximum when demand is low to a minimum when demand is high, the method comprising cooling gas, in a gas storage chamber in open fluid communication with the system with a frozen cooling medium having a freezing point approximately midway between the minimum and maximum boiling points of the gas in the system. When the pressure in the system is high, gas in the chamber liquifies and is stored; when the pressure in the system is low gas in the chamber vaporizes and is available for use.
Abstract:
Gas containment vessels are provided that are comprised of an inner corrosion resistant shell made of lower strength steel alloy or aluminum alloy or thermoplastic polymer, and an outer concentric shell constructed of high strength, albeit lower corrosion resistant, metal or fiber-reinforced composite. The fiber can comprise filaments derived from basaltic rocks, the filaments having been immersed in a thermosetting or thermoplastic polymer matrix, and commingled with carbon, glass or aramid fibers such that there is load sharing between the basaltic fibers and carbon, glass or aramid fibers.
Abstract:
A device for storing and supplying ammonia to an exhaust line of an automobile vehicle, includes a solid material provided for absorbing the ammonia, a reservoir for storing the solid material, and a heating unit to heat the solid material to desorb the ammonia. The solid material comprises solid elements with a mass of less than 50 grams. The heating unit is insulated from the reservoir. The device also includes a first assembly for transferring solid elements from the reservoir to the heating unit.
Abstract:
A vessel is disclosed, the vessel including a main body having a hollow interior for receiving a fluid therein, wherein at least a portion of the hollow interior includes a filling material disposed therein to minimize a rate of flow of the fluid from the main body, wherein the filling material is at least one of a porous structured material and a granulate material.
Abstract:
A vessel for holding a pressurized fluid is disclosed, the vessel having a hollow inner shell formed from a moldable material and forming a cavity therein, an intermediate shell formed over the inner vessel, and an outer shell formed over said intermediate shell, said outer shell having a ceramic layer formed on an outer surface thereof.
Abstract:
Gas container and method for filling a container with gas. The method includes inserting an electrically conducting stretched material into the container before inserting gas into the container, electrically connecting to an electrical ground and at least one of the electrically conducting stretched material and an area in a vicinity of an outlet opening of a filling pipe for inserting the gas into the container, and inserting gas into the container under compression.
Abstract:
Provided are a gas storage structure and a gas storage apparatus including the gas storage structure. The gas storage structure includes a gas storage part including an opening thereon and an entrance control part disposed on the opening and including a gate.
Abstract:
A method for recharging a high pressure gas storage container unit comprises transporting a recharge gas container containing a fluid at a cryogenic temperature and low pressure; heating the fluid in the recharge gas container and the fluid expelled from the recharge gas container to ambient temperature; and filling the high pressure gas storage container with the heated fluid as a pressurized gas. A system for recharging gas at a high pressure level comprises a recharge gas container unit comprising a means for containing cryogenic liquid and a first means for heating the liquid, the first heating means disposed near an outlet portion of the containing means; a second means for heating operatively connected to the recharge gas container unit during recharge; and a high pressure storage container unit comprising means for storing gas at a high pressure, said storing means operatively connected to the second means for heating during recharge.
Abstract:
The invention comprehends a tank for storing fluid under pressure and a method for manufacturing the tank. The tank has an inner core of an open-celled foam that is characterized by open voids that are at least partially interconnected by passages and are surrounded by a fibrous or ligament structure/network (collectively, “ligaments”). Attached to the inner core is an outer skin.
