Abstract:
A storage apparatus for storing a pressurised fluid comprises an outer vessel (2) and a plurality of separately sealed inner vessels (4). Means are provided for communication with the interiors of the inner vessels and of the outer vessel respectively (6,18,12). Also disclosed is a valve (12) for selectively allowing the passage of a fluid. The valve comprises a membrane (14) which is impermeable, within a predetermined temperature range, to the fluid to be stored. It also comprises heating means (16) for raising the temperature of the membrane above said temperature range, thereby allowing the fluid to diffuse through the membrane.
Abstract:
Provided are a subsea storage tank for fluids and a method for building and installing the same. An exemplary embodiment of the present invention provides a subsea storage tank, including: a body having a storage space therein and formed of light weight concrete inner and outer sides of which are watertight coated or plated; a ballast placed on the body of the subsea tank; and a separation unit disposed inside the body and partitioning the storage space upper and lower, the separation unit being movable vertically in the storage space in accordance with the degree of storage fluid filling.
Abstract:
The present invention relates to a gas storage (110)for storing a gaseous medium. The gas storage (110) comprises a membrane (101) which is mounted to the gas storage (110) for at least partially enveloping a storage volume (Vi) of the gas storage (110) and wherein the membrane (101) is made of a flexible material such that the shape of the membrane (101) is adaptable to a filling level of gas in the storage volume (Vi). The membrane (101) comprises a reflection portion (102) for reflecting radar beams. The gas storage (110) further comprises a radar level measurement system for determining the filling level of gas in a storage volume (Vi) of the gas storage (110)by emitting radar beams in the direction to the membrane (101) and for detecting radar beams reflected by the reflection portion(102) of the membrane (101).
Abstract:
A flexible membrane gas accumulator, in particular for storing biogas, comprising a first membrane (1) at least partially defining a gas accumulation chamber (C1) and a second membrane (2) partially defining a pressurizing chamber (C2) adjacent to said accumulation chamber (C1); further comprising means (3) for leading and taking gas, means (4) for pressurizing said pressurizing chamber (C2), means (5) for hooking said membranes and means (6) for detecting the volume of said accumulation chamber (C1) in which a third membrane (7), impermeable to gas and fixed in an impermeable manner at least to said second membrane (2), for defining, in co-operation with the latter, said pressurizing chamber (C2).
Abstract:
The invention relates to a tank for a cryogenic liquid gas, in particular for LNG; that is, for liquid natural gas or liquid methane. The invention further relates to an aircraft having such a tank and to a method for producing such a tank. A tank is produced, which comprises an outer, dimensionally stable structure and a pressure-resistant, cold-resistant film which is able to suitably capture an overpressure resulting from boil-off gas in the tank. The suitably flexible film is coiled so that a hose-shaped chamber or a hose-like sleeve is thus formed. With the aid of the film, a sufficiently pressure-resistant, cold-resistant, light tank for storing cryogenic liquid gas can be provided according to the invention, which can also be subsequently installed in an aircraft primarily due to the flexibility of the film.
Abstract:
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Kraftstoffversorgung eines wasserstoffbetriebenen Kfz, wobei der Wasserstoff durch katalytische Reaktion eines als Kraftstoff vorgesehenen Wasserstoffdonators freigesetzt wird und dabei reagierter, rezyklierbarer Kraftstoff anfällt. Das Verfahren umfasst die Entnahme nicht reagierten Kraftstoffs aus einem ersten Speichervolumen, die Befüllung wenigstens eines zweiten von dem ersten Speichervolumen getrennten Speichervolumens mit reagiertem Kraftstoff und die wenigstens teilweise zusätzliche Nutzung des durch die Entnahme frei werdenden ersten Speichervolumens zur Speicherung des reagierten Kraftstoffs. Eine erfindungsgemäße Kraftstoffbehälter-Anordnung umfasst wenigstens einen Entnahmebehälter (12), der mit Mitteln zur Förderung des Kraftstoffs versehen ist, wenigstens einen Vorratsbehälter (13 a, b, c), der mit dem Entnahmebehälter (12) kommuniziert und mit Mitteln zur Förderung des Kraftstoffs in den Entnahmebehälter (12) versehen ist und einen Sammelbehälter (14), der über einen Überlauf mit einem Vorratsbehälter (13 a, b, c) verbunden ist (Figur 8).
