摘要:
A fluid containment system including a vessel for containing a fluid that is discharged from the vessel in use or operation of the system. A pressure monitoring assembly including a strain-responsive sensor is disposed on an exterior wall surface of the vessel, to sense dynamic strain on the wall surface of such vessel that is incident to discharge of fluid from the vessel, and to responsively output a pressure-indicative response. Such arrangement is particularly useful in application to fluid storage and dispensing vessels containing interiorly disposed pressure regulator assemblies and holding liquefied gases or compressed gases, e.g., for use in semiconductor manufacturing operations.

A hydrogen containing nanostructure is provided, where the hydrogen is adsorbed to the nanostructure by physisorption. The nanostructure includes light elements, selected from the second and third rows of the periodic table. The nanostructure is formed as a layered network of light elements coupled with covalent sp2 bonds. The chemical composition of the nanostructure can be such that the desorption temperature of hydrogen is greater than the liquefaction temperature of nitrogen, 77 K. Further, a hydrogen storage system is provided, including a container and a nanostructured storage material within the container, wherein the nanostructured storage material includes light elements, and the nanostructured storage material is capable of adsorbing hydrogen by physisorption. The hydrogen storage system can include a liquid nitrogen based cooling system, capable of cooling the nanostructured storage material below the desorption temperature of hydrogen. Some embodiments contain a heater to control the temperature of the nanostructured storage material.

The gas storage method comprises a step of keeping a gas to be stored and an adsorbent in a vessel at a low temperature below the liquefaction temperature of the gas to be stored so that the gas to be stored is adsorbed onto the adsorbent in a liquefied state, a step of introducing into the vessel kept at the low temperature a gaseous or liquid medium with a freezing temperature that is higher than the above-mentioned liquefaction temperature of the gas to be stored, for freezing of the medium, so that the gas to be stored which has been adsorbed onto the adsorbent in a liquefied state is encapsulated by the medium which has been frozen, and a step of keeping the vessel at a temperature higher than the liquefaction temperature and below the freezing temperature.
摘要:
A method and apparatus for economically storing and transporting coal mine methane gas is presented. The apparatus utilizes converted propane tankers. Standard propane tankers are filled with activated carbon or commercial carbons with a high volumetric methane adsorption capacity. The methane gas is compressed by a smaller compressor at the well and loaded into the converted tanker. At least three converted tankers are utilized in this method, one being loaded at the well, one discharging its methane gas at the end-user, and one being transported in between the well and the end-user. The truck used to transport the converted tankers has a bi-fuel system adding to the economy of the method and apparatus. Utilizing this apparatus and method of storage and transportation will reduce greenhouse emissions from the mine and from the power plants, and will provide the owner and operator with numerous tax credits and clean air incentives. It also provides the public with a cheaper source of cleaner burning fuel for large public utilities and other large end-users.

A hydrogen storage device prevents localization of hydrogen occlusion alloy and ensures rapid discharge of hydrogen. The hydrogen storage device has a plurality of porous molded pieces arranged longitudinally at predetermined intervals. Conductive cushioning materials are inserted between the molded pieces and between the molded pieces and an adiabatic insulation material. The conductive cushioning materials include first conductive cushioning materials inserted between the adiabatic insulation material and upper and lower end surfaces of the molded pieces and second conductive cushioning materials inserted between left and right end surfaces of the adiabatic insulation material. Disposed at opposed ends of a row of the molded pieces are movable urging electrodes which can move in response to dimensional changes of the molded pieces resulting from their volume changes and which urge the molded pieces to constantly maintain physical contact between the molded pieces and lids.
摘要:
A fluid distribution system for supplying a gas to a process facility such as a semiconductor manufacturing plant. The system includes a main fluid supply vessel coupled by flow circuitry to a local sorbent-containing supply vessel from which fluid, e.g., low pressure compressed gas, is dispensed to a fluid-consuming unit, e.g., a semiconductor manufacturing tool. A fluid pressure regulator is disposed in the flow circuitry or the main liquid supply vessel and ensures that the gas flowed to the fluid-consuming unit is at desired pressure. The system and associated method are particularly suited to the supply and utilization of liquefied compressed gases such as trimethylsilane, arsine, phosphine, and dichlorosilane.
