Abstract
Description
Die Erfindung betrifft einen hydrostatischen Gasverdichter- weiter Gasverdichter genannt nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a hydrostatic gas compressor further called gas compressor according to the preamble of
Hochverdichtete und flüssige Gase und Gasgemische haben einem breiten Anwendungsspektrum als Produktionsmittel, Kühlmittel oder Brennstoff. In der letzten Zeit wird intensiv nach wirtschaftlich effektiven Methoden der Erdgasverflüssigung gesucht da der Gastransport mittels Pipelines sehr investitionsaufwändig, ab bestimmten Pipelinelängen unrentabel und oftmals technisch unmöglich ist. Hierdurch ist von zunehmender Wichtigkeit die Problematik der kostengünstigen Erzeugung vom flüssigen Erdgas bzw. Kühlmittel für die Tiefkühlung des gasförmigen Erdgases in Erdgasverflüssigungsanlagen.High-density and liquid gases and gas mixtures have a wide range of applications as a means of production, coolant or fuel. Recently, the search for efficient natural gas liquefaction methods has been intensively pursued, since pipelines require a lot of investment in the transport of gas, are unprofitable from certain pipeline lengths and are often technically impossible. As a result, the problem of cost-effective production of liquid natural gas or coolant for the deep-freezing of gaseous natural gas in natural gas liquefaction plants is of increasing importance.
Gegenwärtig erfolg die Gasverdichtung für die Gasverflüssigung durch mehrstufige Verdichtung mittels Kompressoren oder Turbinen und stufenweisen Kühlung des Gases in Wärmetauschern. Dabei wird ein Teil vom bereits verdichteten Gas zu Expansion gebracht und für die Kühlung vom restlichen, verdichteten Gas verwendet.At present gas compression for gas liquefaction is achieved by multi-stage compression by means of compressors or turbines and stepwise cooling of the gas in heat exchangers. In this case, a part of the already compressed gas is brought to expansion and used for the cooling of the remaining, compressed gas.
Das gegenwärtige Verfahren ist wegen hohen Investitionskosten der Anlagen und dessen relativ geringen Wirkungsgrad sehr kostenaufwändig. So z. B. reicht es für die Erdgasverflüssigung aus wenn ca. 08–1 Mj/kg. dessen innerer Energie entzogen ist. In der Praxis betrifft, laut einigen Publikationen die Energieaufnahme einer Erdgasverflüssigungsanlage ca. 10–12 Mj/kg. – praktisch bis zu einen viertel von dessen Heizwert. Dabei fällt das größte Anteil des Energieaufwands auf die Komprimierung, Abfuhr der entstandene dabei Wärme und Energieverluste der Anlagen. Da das verflüssigte Erdgas überwiegend auf Seeweg transportiert und oftmals auch in offenen Gewässern gefördert wird wäre es sinnvoll kostengünstig den hydrostatischen Druck der Gewässern zu nutzen und die entstandene bei der Komprimierung Wärme an das Wasser abzuleiten.The current process is very expensive because of the high investment costs of the plants and their relatively low efficiency. So z. For example, it is sufficient for natural gas liquefaction when about 08-1 Mj / kg. whose inner energy is withdrawn. In practice, according to some publications, the energy intake of a natural gas liquefaction plant is about 10-12 Mj / kg. - practically up to a quarter of its calorific value. The largest part of the energy expenditure falls on the compression, dissipation of the resulting heat and energy losses of the plants. Since the liquefied natural gas is mainly transported by sea and often transported in open waters, it would be sensible to use the hydrostatic pressure of the waters at low cost and to dissipate the resulting heat to the water during compression.
In der Erfindung
Der Erfindung liegt die Aufgabe zugrunde ein Gasverdichter mit reibungsfreien beweglichen Komprimierungselementen und effektiven Gaskühlung zu schaffen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst dass die Wände der Kompressionskammer mindestens teilweise aus einem frostsicheren und zerstörungsfreien dehn- und/oder verformbaren Material bestehen und der Gasverdichter mit mindestens einer Wärmeableitungseinrichtung versehen ist.The invention has for its object to provide a gas compressor with friction-free movable compression elements and effective gas cooling. This object is achieved in that the walls of the compression chamber at least partially made of a frost-proof and non-destructive stretchable and / or deformable material and the gas compressor is provided with at least one heat dissipation device.
Durch diese Lösung wird vorteilhaft erreicht dass beim Sinkvorgang die Komprimierkammer vom Bestandteilen des Gewässer nicht verschmutzt wird, die Bauteile aus gängigen kostengünstigen Materialien ohne besonderen Präzisionsanforderungen kostengünstig angefertigt sein können und der Zeit- und Kostenaufwand der Instandhaltung minimal ist. Dabei entfallen der Investition- und Kostenaufwand für den Bau und Betrieb einer Gaskühlungsanlage.By this solution is advantageously achieved that during the sinking the Komprimierkammer is not polluted by constituents of the waters, the components can be made inexpensively from common inexpensive materials without special precision requirements and the time and cost of maintenance is minimal. This eliminates the investment and cost of construction and operation of a gas cooling system.
Als weitere Ausgestaltung ist vorgesehen dass der Druck auf die verformbaren Wände der Komprimierungskammer von mindesten einen, mit dem Gasverdichter integrierten oder separaten Druckmultiplikator erzeugt wird.As a further embodiment it is provided that the pressure on the deformable walls of the compression chamber of at least one, with the gas compressor integrated or separate pressure multiplier is generated.
Diese Lösung ist vorteilhaft für z. B. Fälle, wenn wegen unzureichender Gewässertiefe der notwendige hydrostatische Druck nicht erzeugt sein kann oder wenn der Bau einer Förderanlage für die Druckerzeugung von extrem hohen Komprimierungsgrad in größeren Tiefen finanziell unattraktiv ist.This solution is advantageous for z. As cases, if due to insufficient depth of water, the necessary hydrostatic pressure can not be generated or if the construction of a conveyor system for the pressure generation of extremely high degree of compression at greater depths is financially unattractive.
Durch die Anwendung dieser Lösung wird erfindungsgemäß erreich dass bei geringen Investitionssteigerung man auch in relativ flachen Gewässern im Gasverdichter beliebig hohen Druck erzeugen kann.By applying this solution is achieved according to the invention that at low investment increase can produce any high pressure in relatively shallow waters in the gas compressor.
In Folgenden werden drei Ausführungsbeispiele der Erfindung anhang schematischen Zeichnungen näher erläutert. Es zeigen:In the following three embodiments of the invention will be explained in more detail schematic drawings. Show it:

Nach diesem Vorgang wird das Gas durch zusätzliche, auf der Zeichnung nicht dargestellte, dem Stand der Technik bekannter Vorrichtung auf bekannte Art aus dem Gasverdichter zur Weiterverwertung entnommen. Danach wird der Vorgang wiederholt. - 2. Das hochkomprimierte Gas wird durch öffnen des versperrbaren Gasanschlusses (

After this process, the gas is removed by additional, not shown in the drawing, known in the prior art device in a known manner from the gas compressor for further use. Thereafter, the process is repeated. - 2. The highly compressed gas is released by opening the lockable gas connection (
