Erfindungsgemäß wird das Gas oberhalb seines kritischen Punktes gespeichert, wobei die Speichertemperatur maximal 5 K über der kritischen Temperatur des Gases und der Speicherdruck maximal 30 bar über dem kritischen Druck des Gases liegt.A method for storing gases, in particular natural gas, is described. According to the invention, the gas is stored above its critical point, the storage temperature being a maximum of 5 K above the critical temperature of the gas and the storage pressure being a maximum of 30 bar above the critical pressure of the gas.

Description

Die Erfindung betrifft ein Verfahren zur Speicherung von Gasen, insbesondere von Erdgas.The invention relates to a method for storing gases, in particular natural gas.

Gegenwärtig werden Gase, insbesondere Erdgas, in zwei Aggregatzuständen gespeichert und transportiert, nämlich als Druckgas (CNG) oder im verflüssigten, tiefkalten Zustand (LNG). Bei einer Speicherung als Druckgas wird das Erdgas üblicherweise auf einen Druck von wenigstens 200 bar verdichtet und in Druckgasspeicher bzw. -behälter gefüllt. Diese haben aufgrund der erforderlichen massiven Bauweise ein vergleichsweise hohes Gewicht und begrenzen dadurch die zu transportierende Menge, da die üblicherweise zum Einsatz kommenden CNG-Trailer Gewichtsbeschränkungen unterworfen sind. Bei einer Speicherung als Flüssigprodukt ist zwar die Dichte des Mediums höher, jedoch erfordert die Verflüssigung einen vergleichsweise hohen energetischen Aufwand. Zudem sind die Transportbehälter aufgrund der notwendigen Vakuumisolierung konstruktiv vergleichsweise aufwendig. Des Weiteren ist der Transport aufgrund der geltenden ADR (Europäisches Übereinkommen über die Beförderung gefährlicher Güter auf der Straße) nur eingeschränkt möglich. Der Transport von Erdgas ist deshalb oftmals nicht wirtschaftlich sinnvoll, da die Transportmengen limitiert sind oder der für die Herstellung des Flüssigproduktes erforderliche Aufwand zu hoch ist.At present, gases, in particular natural gas, are stored and transported in two states of aggregation, namely as compressed gas (CNG) or in the liquefied, low-temperature state (LNG). When stored as compressed gas, the natural gas is usually compressed to a pressure of at least 200 bar and filled in compressed gas storage or container. These have due to the required solid construction, a comparatively high weight and thereby limit the amount to be transported, since the usually used CNG trailer are subjected to weight restrictions. When stored as a liquid product, although the density of the medium is higher, but the liquefaction requires a relatively high energy expenditure. In addition, the transport container due to the necessary vacuum insulation structurally relatively expensive. Furthermore, transport is only partially possible due to the current ADR (European Agreement concerning the Carriage of Dangerous Goods by Road). The transport of natural gas is therefore often not economically viable, since the transport quantities are limited or required for the production of the liquid product effort is too high.

Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Verfahren zur Speicherung von Gasen, insbesondere von Erdgas, anzugeben, das die vorgenannten Nachteile vermeidet.The object of the present invention is to provide a generic method for storing gases, in particular natural gas, which avoids the aforementioned disadvantages.

Zur Lösung dieser Aufgabe wird ein Verfahren zur Speicherung von Gasen, insbesondere von Erdgas, vorgeschlagen, das dadurch gekennzeichnet ist, dass das Gas oberhalb seines kritischen Punktes gespeichert wird, wobei die Speichertemperatur maximal 5 K über der kritischen Temperatur des Gases und der Speicherdruck maximal 30 bar über dem kritischen Druck des Gases liegt.To solve this problem, a method for storing gases, in particular natural gas, proposed, which is characterized in that the gas is stored above its critical point, the storage temperature at most 5 K above the critical temperature of the gas and the accumulator pressure a maximum of 30 bar is above the critical pressure of the gas.

Sofern es sich bei dem zu speichernden Gas um Erdgas handelt, erfolgt dessen Speicherung erfindungsgemäß bei einem Druck zwischen 46 und 80 bar, vorzugsweise zwischen 48 und 50 bar, und bei einer Temperatur zwischen –75 und –88°C, vorzugsweise, zwischen –80 und –85°C.If the gas to be stored is natural gas, it is stored according to the invention at a pressure between 46 and 80 bar, preferably between 48 and 50 bar, and at a temperature between -75 and -88 ° C, preferably between -80 and -85 ° C.

Erfindungsgemäß erfolgen Speicherung und Transport bei einem Aggregatzustand, der sich zwischen den oben genannte Zuständen „gasförmig und „flüssig” im sog. superkritischen Zustand befindet. Diese Verfahrensweise ermöglicht es, größere Mengen kostengünstiger zu speichern und zu transportieren, wobei der bei der Überschreitung der Gas-Flüssig-Phasengrenze auftretende, energetische Nachteil vermieden werden kann.According to the invention storage and transport in an aggregate state, which is located between the above-mentioned states "gaseous and" liquid "in the so-called. Supercritical state. This procedure makes it possible to store and transport larger quantities more cost-effectively, whereby the energy disadvantage occurring when the gas-liquid phase boundary is exceeded can be avoided.

Die Speicherung von Erdgas erfolgt vorzugsweise bei einem überkritischen Druck von 46 bis 80 bar und bei einer überkritischen Temperatur von bis zu –86°C. Damit kann Erdgas in einem für einen Maximaldruck von 50 bar ausgelegten Druckbehälter gespeichert und transportiert werden. Daraus resultiert insbesondere eine Erhöhung der Transportmenge, da derartige Druckbehälter im Vergleich zu den bisher zum Einsatz kommenden Druckgasspeicher eine wesentlich geringere Masse aufweisen.The storage of natural gas is preferably carried out at a supercritical pressure of 46 to 80 bar and at a supercritical temperature of up to -86 ° C. This allows natural gas to be stored and transported in a pressure vessel designed for a maximum pressure of 50 bar. This results in particular in an increase in the transport quantity, since such pressure vessels have a substantially lower mass in comparison to the compressed gas accumulators previously used.

Anstelle der bisher verwendeten Druckgasspeicher und Speicherbehälter mit Vakuumisolierung können nunmehr konstruktiv weniger aufwendige Speicherbehälter, die eine konventionelle Isolierung, bspw. in Form einer PU-Isolierung, aufweisen, verwendet werden.Instead of the previously used compressed gas storage and storage tanks with vacuum insulation can now constructively less expensive storage tank, which have a conventional insulation, for example. In the form of PU insulation, are used.

Das erfindungsgemäße Verfahren zur Speicherung von Gasen, insbesondere von Erdgas, weist gegenüber den zum Stand der Technik zählenden Verfahren folgende Vorteile auf:

  • – Höhere Transportkapazität im Vergleich zu einer CNG-Speicherung
  • – Niedrigerer Energieaufwand im Vergleich zu einer LNG-Speicherung
  • – Keine Einschränkungen aufgrund der geltenden ADR
The inventive method for storing gases, in particular natural gas, has the following advantages over the prior art methods:
  • - Higher transport capacity compared to CNG storage
  • - Lower energy consumption compared to LNG storage
  • - No restrictions due to the current ADR
