Description
Die Erfindung betrifft ein Verfahren zum Abkühlen oder Verflüssigen eines Kohlenwasserstoff-reichen Stromes, beispielsweise eines Erdgasstromes, wobei die Abkühlung oder Verflüssigung des Kohlenwasserstoff-reichen Stromes gegen wenigstens einen Kältemittelkreislauf, gegen wenigstens einen Kältemittelgemischkreislauf oder gegen eine beliebige Kombination aus wenigstens einem Kältemittelkreislauf und wenigstens einem Kältemittelgemischkreislauf erfolgt.The The invention relates to a method for cooling or liquefying a Hydrocarbon-rich stream, such as a natural gas stream, with the cooling or liquefaction of the Hydrocarbon-rich stream against at least one refrigerant circuit, against at least one refrigerant mixture cycle or against any combination of at least one refrigerant circuit and at least one mixed refrigerant cycle he follows.
Aus dem Stand der Technik sind eine Vielzahl gattungsgemäßer Verfahren zum Abkühlen oder Verflüssigen eines Kohlenwasserstoff-reichen Stromes bekannt, bei denen die Abkühlung oder Verflüssigung des Kohlenwasserstoff-reichen Stromes gegen unterschiedlichst ausgebildete Kältemittel(gemisch)kreisläufe oder gegen beliebige Kombinationen aus wenigstens einem Kältemittelkreislauf und wenigstens einem Kältemittelgemischkreislauf erfolgen.Out The prior art is a variety of generic methods to cool down or liquefying a hydrocarbon-rich stream known in which the cooling or liquefaction of the hydrocarbon-rich stream against most diverse trained Refrigerant (mixture) circuits or against any combinations of at least one refrigerant circuit and at least one mixed refrigerant cycle respectively.
Lediglich beispielhaft genannt seien sog. Single-Flow-Verflüssigungsprozesse, Dual-Flow-Verflüssigungsprozesse sowie der von der Anmelderin entwickelte Mixed-Fluid-Cascade-Verflüssigungsprozess. Sämtlichen, zum Stand der Technik zählenden Verflüssigungsprozessen ist gemein, dass das in ihnen zirkulierende Kältemittel und/oder Kältemittelgemisch verdichtet werden muss. Hierzu kommen üblicherweise Kolben-, Schrauben- oder Turbo-Verdichter zur Anwendung.Only Examples include so-called single-flow liquefaction processes, Dual-flow liquefaction processes and the Applicant's mixed fluid cascade liquefaction process. all, to the state of the art counting liquefaction processes is common that the circulating in them refrigerant and / or refrigerant mixture must be compressed. These usually come piston, screw or turbo-compressor for use.
In der jüngeren Vergangenheit sind bereits eine Vielzahl der vorgenannten gattungsgemäßen Verflüssigungsprozesse im Rahmen von schwimmenden LNG-Anlagen – sog. Floating-LNG-Anlagen – konzipiert worden. Insbesondere derartige Anlagen bzw. Prozesse erfordern Komponenten und Bauteile, die eine kompakte Bauweise aufweisen und darüber hinaus vergleichsweise einfach und kostengünstig gewartet werden können. Die bis dato in Betracht gezogenen, vorgenannten Verdichtertypen eignen sich für derartige schwimmende LNG-Anlagen nur bedingt, da sie zum einen vergleichsweise groß bauen und zum anderen einen hohen Wartungsbedarf aufweisen.In the younger ones The past are already a variety of the aforementioned generic liquefaction processes in the framework of floating LNG plants - so-called floating LNG plants - designed Service. In particular, such systems or processes require components and components that have a compact design and beyond can be maintained comparatively easy and inexpensive. The to date considered, aforementioned compressor types are suitable for such floating LNG plants only conditionally, as they are on the one hand build comparatively large and on the other hand have a high maintenance requirement.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Verfahren zum Abkühlen oder Verflüssigen eines Kohlenwasserstoff-reichen Stromes, beispielsweise eines Erdgasstromes, anzugeben, das die vorbeschriebenen Nachteile vermeidet.task The present invention is a generic method to cool down or liquefying a hydrocarbon-rich stream, such as a natural gas stream, specify that avoids the disadvantages described above.
Zur Lösung dieser Aufgabe wird ein Verfahren zum Abkühlen oder Verflüssigen eines Kohlenwasserstoff-reichen Stromes, beispielsweise eines Erdgasstromes, vorgeschlagen, das dadurch gekennzeichnet ist, dass das oder wenigstens eines der Kältemittel und/oder Kältemittelgemische, das bzw. die einer Verdichtung unterworfen werden, innerhalb des Kältemittelkreislaufes und/oder Kältemittelgemischkreislaufes zumindest teilweise kondensiert vorliegen und bei allen Verfahrenszuständen, insbesondere an der oder den Verdichtersaugseiten eine molare Dichte von wenigstens 0,30 kmol/m3, vorzugsweise von wenigstens 0,35 kmol/m3, aufweisen.To solve this problem, a method for cooling or liquefying a hydrocarbon-rich stream, such as a natural gas stream, proposed, which is characterized in that the or at least one of the refrigerant and / or refrigerant mixtures, which are subjected to a compaction, within of the refrigerant circuit and / or mixed refrigerant cycle are present at least partially condensed and at all process states, in particular at the compressor suction side or sides, a molar density of at least 0.30 kmol / m 3 , preferably at least 0.35 kmol / m 3 .
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens zum Abkühlen oder Verflüssigen eines Kohlenwasserstoff-reichen Stromes, die Gegenstände der abhängigen Patentansprüche darstellen, sind dadurch gekennzeichnet, dass
- – die Verdichtung des oder wenigstens eines der Kältemittel und/oder Kältemittelgemische mittels eines Einwellen-Zentrifugalverdichters mit vertikal geteiltem Gehäuse erfolgt,
- – der Verdichter-Saugdruck wenigstens 5 bis 10 bar, vorzugsweise wenigstens 8 bar beträgt und
- – der Verdichter-Enddruck wenigstens 30 bis 70 bar, vorzugsweise wenigstens 50 bar beträgt.
- The compression of the or at least one of the refrigerants and / or refrigerant mixtures takes place by means of a vertically split-housing single-shaft centrifugal compressor,
- - The compressor suction pressure is at least 5 to 10 bar, preferably at least 8 bar and
- - The compressor discharge pressure is at least 30 to 70 bar, preferably at least 50 bar.
Die vorgenannten Einwellen-Zentrifugalverdichter mit vertikal geteiltem Gehäuse werden auch als Topfverdichter oder "Barrel Type Compressor" bezeichnet.The aforesaid single-shaft centrifugal centrifugal compressors casing are also referred to as a pot compressor or "barrel type compressor".
Derartige Einwellen-Zentrifugalverdichter weisen im Gegensatz zu den o. g. Verdichterkonstruktionen eine kompakte Bauweise auf und erfordern zudem einen geringeren Wartungsaufwand als bekannte Verdichterkonstruktionen. Insbesondere für die vorbeschriebene Anwendung bei schwimmenden LNG-Anlagen sind sie daher besonders vorteilhaft geeignet.such Single-shaft centrifugal compressors, in contrast to the o. G. Compressor designs have a compact design and require In addition, a lower maintenance than known compressor designs. Especially for the they are the above-described application for floating LNG plants therefore particularly advantageous.
Da ihr Saugvolumen jedoch begrenzt ist, lassen sich attraktive Anlagengrößen und Verflüssigungsleistungen nur dann realisieren, wenn man eine Anhebung des Druckniveaus in dem oder den Kältemittel(gemisch)kreisläufen zulässt. Dies führt jedoch zwangsläufig zu höheren Dichten, die thermodynamisch von Nachteil und daher unerwünscht sind. Nachdem jedoch diese höheren Dichten die Verwendung derartiger Einwellen-Zentrifugalverdichter erst in vernünftiger Weise ermöglichen, muss dieser Nachteil in Kauf genommen werden.There However, their suction volume is limited, can be attractive system sizes and liquefaction services only realize, if one raises the pressure level in the refrigerant or (refrigerant) cycles allowed. This leads however inevitably to higher Densities that are thermodynamically disadvantageous and therefore undesirable. However, after these higher Dense the use of such single shaft centrifugal compressors only in reasonable Allow way This disadvantage must be accepted.
