The outer container storage zone (3) is filled with a gas or gas mixture which is free of oxygen, or an inert gas. The inner container has a monitor (5,6) to register a gas concentration. The gas storage container (2), with a flexible shape, is of a gas-permeable material e.g. coated rubber or textile-reinforced polyester shrouded by an outer container (4) of a gas-permeable material and/or of a gas-impermeable material. The gas storage container has a system (7,8) to feed gas or a gas mixture into and out of the storage zones (1,3) within the container. The outer container storage zone (3) is filled with a gas or gas mixture which is free of oxygen, or an inert gas. The inner container has a monitor (5,6) to register a gas concentration, and preferably the level of oxygen present. The pressure and/or volume changes in one of the containers is controlled by adjusting the pressure and/or volume in the other container.

Description

Die Erfindung betrifft einen nicht formbeständigen Speicherbehälter, insbesondere für die Speicherung von Gasen und/oder Gasgemischen, bestehend im Wesentlichen aus einem gasdurchlässigen Material, beispielsweise aus beschichtetem Gummi oder aus textilverstärktem Polyester.The invention relates to a non-dimensionally stable storage container, in particular for the storage of gases and / or gas mixtures, consisting essentially of a gas-permeable material, for example made of coated rubber or textile reinforced polyester.

Ferner betrifft die Erfindung ein Verfahren zum Speichern eines oder mehrerer Gase oder Gasgemische in einem derartigen Speicherbehälter.The invention further relates to a method for storing one or more gases or gas mixtures in such a storage container.

Hochdruckgas-Abschreckeinrichtungen werden im Regefall mit gasförmigem Helium bei einem Druck von mehr als 10 bar betrieben. Bei der Gaseversorgung derartiger Anlagen mit Helium wird das Helium aus Kostengründen im Kreislauf gefahren und entweder in entsprechenden Druckbehältern - gefertigt aus Stahl, Aluminium, Kupfer, etc. - oder nicht formbeständigen, insbesondere ballonförmigen Speicherbehältern bzw. Ballons (zwischen)gelagert. Während Druckbehälter sowohl zur Entspannung als auch zur Lagerung von Gasen genutzt werden, kommen die vorgenannten, nicht formbeständigen Speicherbehälter mit wenigen Ausnahmen als Entspannungsbehälter zum Einsatz.High-pressure gas quenching devices are usually made with gaseous helium operated at a pressure of more than 10 bar. In the gas supply of such In helium plants, the helium is circulated for cost reasons and either in appropriate pressure vessels - made of steel, aluminum, copper, etc. - or non-dimensionally stable, in particular balloon-shaped storage containers or balloons (temporarily) stored. While pressure vessels for both relaxation and the aforementioned are not used for the storage of gases dimensionally stable storage tank with a few exceptions as a relaxation tank for use.

Die Verwendung der vorgenannten Druckbehälter hat u. a. den Vorteil, dass die Reinheit des in ihnen gespeicherten Gases relativ unabhängig von der Lagertechnologie ist.The use of the aforementioned pressure vessel has u. a. the advantage that the Purity of the gas stored in them is relatively independent of the Warehouse technology is.

Nachteilig hierbei ist jedoch, dass die Anlagen- bzw. Investitionskosten vergleichsweise hoch sind, was ebenso für den Überwachungsaufwand derartiger Druckbehälter gilt.The disadvantage here, however, is that the system and investment costs are comparatively high are high, which also applies to the monitoring effort of such pressure vessels.

Kommen die vorgenannten nicht formbeständigen Speicherbehälter zur Anwendung, kommt es durch die physikalisch bedingte Diffusion von Luftsauerstoff und anderen Gasarten durch die Speicherbehälterwand zum einen zu erheblichen zusätzlichen Gasverlusten und zum anderen zu einer Verunreinigung des in dem nicht formbeständigen Speicherbehälter gelagerten Gases oder Gasgemisches. Wird beispielsweise für den eingangs beschriebenen Anwendungszweck - Hochdruckgas- Abschreckung mittels Helium - Helium in einem nicht formbeständigen Speicherbehälter gelagert, so hat zwar die Diffusion von Stickstoff - zumindest bis zu einem Stickstoffgehalt von ca. 15 Vol.-% - keine Nachteile, unter bestimmten Bedingungen können mit einem entsprechenden Helium/Stickstoff-Gasgemisch sogar verbesserte Abschreckbedingungen erreicht werden, jedoch erfordert die Beseitigung des eindiffundierten Sauerstoffes entweder ein Austauschen des Heliums in regelmäßigen Abständen oder das Einbinden einer entsprechenden adsorptiven und/oder permeativen Gasreinigungsvorrichtung, mittels der der Sauerstoff aus dem Helium entfernt werden kann.If the aforementioned non-dimensionally stable storage containers are used, it comes from the physical diffusion of atmospheric oxygen and others Gas types through the storage container wall on the one hand to considerable additional Gas losses and on the other hand to contamination of the in the not dimensionally stable storage container of stored gas or gas mixture. Becomes for example for the application described above - high pressure gas  Quenching with helium - helium in a non-dimensionally stable Storage tanks stored, so has the diffusion of nitrogen - at least up to a nitrogen content of about 15 vol .-% - no disadvantages, under certain Conditions can even with an appropriate helium / nitrogen gas mixture improved quenching conditions can be achieved, however, requires elimination of the diffused oxygen either by exchanging the helium in regular intervals or the incorporation of a corresponding adsorptive and / or permeative gas cleaning device, by means of which the oxygen from the Helium can be removed.

Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen nicht formbeständigen Speicherbehälter sowie ein gattungsgemäßes Verfahren zum Speichern eines oder mehrerer Gase oder Gasgemische in einem derartigen Speicherbehälter anzugeben, der bzw. das die vorgenannten Nachteile vermeidet. Insbesondere sollen die Verunreinigung(en) und Gasverluste reduziert, die Anlagen- und Prozesssicherheit erhöht und die Investitions- sowie die Betriebskosten reduziert werden.The object of the present invention is not a generic dimensionally stable storage container and a generic method for Store one or more gases or gas mixtures in one Specify storage container that avoids the aforementioned disadvantages. In particular, the pollution (s) and gas losses should be reduced, the plant and increased process reliability and reduced investment and operating costs become.

Zur Lösung dieser Aufgabe wird ein gattungsgemäßer nicht formbeständigen Speicherbehälter vorgeschlagen, der dadurch gekennzeichnet ist, dass der nicht formbeständige Speicherbehälter von wenigstens einem weiteren Speicherbehälter, der ebenfalls im Wesentlichen aus einem gasdurchlässigen Material besteht, und/oder von wenigstens einem weiteren Speicherbehälter, der aus einem nicht gasdurchlässigen Material besteht, umgeben ist.To solve this problem, a generic one is not dimensionally stable Storage container proposed, which is characterized in that the not dimensionally stable storage container of at least one further storage container, which likewise essentially consists of a gas-permeable material, and / or of at least one other storage container that does not consist of one gas permeable material is surrounded.

Das erfindungsgemäße Verfahren zum Speichern eines oder mehrerer Gase oder Gasgemische in einem gattungsgemäßen Speicherbehälter zeichnet sich dadurch aus, dass der oder die äußeren Speicherräume mit einem Sauerstoff-freien Gas oder Gasgemisch gefüllt sind bzw. werden.The inventive method for storing one or more gases or Gas mixtures in a generic storage container are characterized in that that the outer storage space or spaces with an oxygen-free gas or Gas mixture are or will be filled.

Erfindungsgemäß ist der nicht formbeständige, innere Speicherbehälter nunmehr nicht unmittelbar der Umgebungsluft "ausgesetzt", sondern zwischen ihm und der Umgebungsluft wird wenigstens ein weiterer äußerer Speicherraum, der als Puffer zwischen dem inneren Speicherraum und der Umgebungsluft dient, vorgesehen. According to the invention, the non-dimensionally stable inner storage container is now not directly "exposed" to the ambient air, but between it and the Ambient air becomes at least one other outer storage space, which acts as a buffer between the inner storage space and the ambient air is provided.  

Dieser äußere Speicherraum kann nun gemäß dem Kennzeichen des Patentanspruches 1 entweder durch einen weiteren, nicht formbeständigen Speicherbehälter, der ebenfalls im Wesentlichen aus dem gleichen Material wie der innere, nicht formbeständige Speicherbehälter besteht, oder von einem weiteren Speicherbehälter, der aus einem nicht gasdurchlässigen Material besteht, umgeben sein. Im Falle der letztgenannten Alternative kann als äußerer Speicherbehälter beispielsweise eine Blechummantelung des inneren, nicht formbeständigen Speicherbehälters vorgesehen werden.This outer storage space can now according to the characteristics of Claim 1 either by another, not dimensionally stable Storage container, which is also essentially made of the same material as the inner, non-dimensionally stable storage container, or from another Storage container, which consists of a non-gas permeable material, surrounded his. In the case of the latter alternative, it can be used as an external storage container for example, a sheet metal casing of the inner, not dimensionally stable Storage container are provided.

Unabhängig davon, welche der beiden Lösungen gewählt wird, ist das in dem inneren Speicherraum befindliche Gas oder Gasgemisch nunmehr nicht mehr unmittelbar der Umgebungsluft "ausgesetzt".Regardless of which of the two solutions is chosen, this is on the inside Storage space gas or gas mixture is no longer directly the Ambient air "exposed".

Gemäß einer vorteilhaften Weiterbildung des erfindungsgemäßen Speicherbehälters bzw. des erfindungsgemäßen Verfahrens sind der oder die äußeren Speicherräume mit einem Sauerstoff-freien Gas oder Gasgemisch gefüllt. Hierbei kommen vorzugsweise ein inertes Gas oder Gasgemisch, wie beispielsweise Stickstoff, Argon, Kohlendioxid oder SF6 bzw. Gasgemische, die die vorgenannten Komponenten enthalten, zur Anwendung.
