Abstract:
A high-pressure vessel fabrication and methods of fabrication are disclosed. An exemplary vessel includes a gas-tight inner liner fabrication, an outer structural overwrap fabricated by reinforcing a filament winding onto the gas-tight inner liner, and an overwrap polymerization. Prior to rotational molding of an inner seamless polymer liner, nozzles are manufactured for subsequent installation into a rotational mold that have grooves on both surfaces of embedded portions and a raised ring shoulder on the surface of a bore near an outlet of the nozzle.
Abstract:
The present invention relates to a tank device for storing hydrogen for an aircraft. The tank device comprises an outer tank (1) and an inner tank (7). The inner tank (7) is held in the outer tank (1). The outer tank (1) is arranged such that the hydrogen with first physical characteristics can be stored. The inner tank (7) is designed such that the hydrogen with second physical characteristics can be stored. The outer tank (1) is connected to the inner tank (7) such that the hydrogen can be fed to the inner tank (7) from the outer tank (1). The inner tank (7) is designed such that the hydrogen with the first physical characteristics can be converted to the hydrogen with second physical characteristics. The inner tank (7) is arranged such that the hydrogen comprising the second physical characteristics can be fed to a consumer.
Abstract:
The present invention is a tank suitable to contain high pressure fluids, especially for compressed natural gas used for automotive purposes. The tank has a discoid shape to be easily placed on board of vehicles. The tank comprises a sealed internal core and an external coating made through a twisted coats fiber wrapping of composite material with a very high mechanical tensile resistance. According to some executive variants, the tank internally comprises a reinforcing structure made up of a plurality of elements welded in contact with the internal surface of the core.
Abstract:
A system is provided for offshore offloading and regasification of LNG from an LNG tanker (1), which system is connected to a natural gas receiving system and includes a plurality of mooring and offloading systems (5) and a plurality of regasification vessels (2), to which mooring and offloading system (5) an LNG tanker is moored, and a regasification vessel (2) is connected to the LNG tanker (1) for offloading regasified LNG into the receiving system, LNG being offloaded from the LNG tanker (1) and regasified via the regasification vessel (2). A method is also provided for offshore offloading and regasification of LNG from an LNG tanker (1) for delivery to a natural gas receiving system, including the steps of: providing a plurality of mooring and offloading systems (5) and a plurality of regasification vessels (2); connecting a regasification vessel (2) to the LNG tanker (1); mooring the LNG tanker (1) to the mooring and offloading system (5); connecting the regasification vessel (2) to the mooring and offloading system (5); offloading LNG onto the regasification vessel (2) from the LNG tanker (1); regasifying LNG in the regasification vessel (2); and offloading LNG into the receiving system from the regasification vessel (2). The system and the method permit the use of standard LNG tankers without any modification.
Abstract:
A vessel for transporting liquefied natural gas is provided. The vessel generally includes a gas transfer system for on-loading and off-loading natural gas to and from the vessel at essentially ambient temperature. The vessel further includes a gas processing facility for selectively providing liquefaction and regasification of the natural gas. The vessel also includes a containment structure for containing the liquefied natural gas during transport. The vessel may be a marine vessel or a barge vessel for transporting LNG over water, or a trailer vessel for transporting LNG overthe-road. A method for transporting LNG is also provided, that provides on-loading of natural gas onto a vessel, condensing the natural gas, storing the gas on the vessel in liquefied form, transporting the gas to an import terminal, vaporizing the gas, and off-loading the gas at the terminal.
Abstract:
A storage system and its manufacturing method, for an adsorbing gas includes a plurality of briquette units situated within a storage tank. Each briquette unit includes an open vessel or liner and compressed gas-absorbing particulate matter, which particulate matter includes activated carbon, zeolite, and other appropriate hydrocarbon gas and/or hydrogen adsorbing materials. Optionally, each unit can include a wrapper for preventing circulation of the particulate matter within the storage tank and the storage system can include a mechanism for supplying or removing heat to at least one of the briquette units. Methane powered vehicles, such as automobiles, buses, trucks, and ships can include the above described storage system with compressed methane-adsorbing particulate matter.
