Description
Die Erfindung betrifft ein Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion, wobei die Kohlenwasserstoff-reiche Fraktion gegen einen offenen Expander-Kältekreislauf verflüssigt wird.The invention relates to a process for liquefying a hydrocarbon-rich fraction, wherein the hydrocarbon-rich fraction is liquefied against an open expander refrigeration cycle.
Gattungsgemäße Verfahren zum Verflüssigen Kohlenwasserstoff-reicher Fraktionen kommen beispielsweise bei der Verflüssigung von Erdgas zur Anwendung. Unter einem offenen Expander-Kältekreislauf versteht man einen Verflüssigungsprozess, bei dem ein Teilstrom der zur verflüssigenden (Kohlenwasserstoff-reichen) Einsatzfraktion vor der Abkühlung und Verflüssigung abgezogen, abgekühlt, kälteleistend entspannt und anschließend im Gegenstrom zu der zu verflüssigenden (Kohlenwasserstoff-reichen) restlichen Einsatzfraktion angewärmt wird. Offene Expander-Kältekreisläufe erfordern daher kein zusätzliches bzw. importiertes Kältemittel oder Kältemittelgemisch, weswegen die Kältemittel(gemisch)verfügbarkeit am gewählten Standort des Verflüssigungsprozesses keine Rolle spielt. Verflüssigungsanlagen, in denen derartige Prozesse realisiert werden, sind daher bzgl. ihrer Standortwahl sehr flexibel. Unter dem Begriff „Kältemittel” seien nachfolgend ein- oder mehrkomponentige Kältemittel zu verstehen.Generic processes for liquefying hydrocarbon-rich fractions are used, for example, in the liquefaction of natural gas. An open expander refrigeration cycle is understood as meaning a liquefaction process in which a substream of the liquefied (hydrocarbon-rich) feed fraction is withdrawn before cooling and liquefaction, cooled, relieved at low temperatures and then countercurrently to the residual hydrocarbon fraction (hydrocarbon-rich) remaining feed fraction is warmed up. Therefore, open expander refrigeration circuits do not require any additional or imported refrigerant or refrigerant mixture, and therefore the refrigerant (mixing) availability at the selected location of the liquefaction process is irrelevant. Liquefaction plants, in which such processes are realized, are therefore very flexible with regard to their choice of location. The term "refrigerant" is to be understood below single-component or multi-component refrigerant.
Bei der Verflüssigung Kohlenwasserstoff-reicher Fraktionen, insbesondere von Erdgas, kommen offene Expander-Kältekreisläufe zur Anwendung, bei denen der als Kältemittel abgezweigte Teilstrom der zu verflüssigenden Einsatzfraktion in einer Entspannungsstufe, vorzugsweise mittels eines Expanders, kälteleistend entspannt wird. Im Vergleich zu sog. geschlossenen Expander-Kältekreisläufen sowie zu Gemischkreisläufen weisen offene Expander-Kältekreisläufe einen vergleichsweise schlechten energetischen Wirkungsgrad auf. Sie wurden aus diesem Grunde in der Vergangenheit üblicherweise nur bei kleineren Verflüssigungsanlagen – hierunter seien Anlagen mit einer Verflüssigungsleistung von wenigen hundert Tonnen LNG pro Tag zu verstehen – in Betracht gezogen.In the liquefaction of hydrocarbon-rich fractions, in particular of natural gas, open expander refrigeration circuits are used, in which the branched off as a refrigerant partial flow of the feed fraction to be liquefied in a relaxation stage, preferably by means of an expander, is cooled performance. Compared to so-called closed expander refrigeration circuits and to mixture cycles, open expander refrigeration circuits have a comparatively poor energy efficiency. For this reason, they have traditionally only been considered in the past for smaller liquefaction plants - these are plants with a liquefaction capacity of a few hundred tonnes of LNG per day.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion anzugeben, das einen im Vergleich zu den zum Stand der Technik zählenden Verflüssigungsprozessen mit offenen Expander-Kältekreisläufen besseren energetischen Wirkungsgrad aufweist.The object of the present invention is to provide a generic method for liquefying a hydrocarbon-rich fraction, which has a better energy efficiency compared to the state of the art counting liquefaction processes with open expander refrigeration circuits.
Zur Lösung dieser Aufgabe wird ein Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion vorgeschlagen, das dadurch gekennzeichnet ist, dass der in dem offenen Expander-Kältekreislauf zirkulierende Teilstrom der zu verflüssigenden Kohlenwasserstoff-reichen (Einsatz)Fraktion zweistufig arbeitsleistend entspannt wird, wobei der in der ersten Entspannungsstufe entspannte Teilstrom abgekühlt und anschließend der zweiten Entspannungsstufe zugeführt wird.To solve this problem, a method for liquefying a hydrocarbon-rich fraction is proposed, which is characterized in that in the open expander refrigerant circuit circulating partial stream of liquefied hydrocarbon-rich (use) fraction is two-stage work expanded, the in the first relaxation stage relaxed partial flow cooled and then the second expansion stage is supplied.
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens zum Verflüssigen einer Kohlenwassserstoff-reichen Fraktion, die Gegenstände der abhängigen Patentansprüche darstellen, sind dadurch gekennzeichnet, dass
- – der in dem offenen Expander-Kältekreislauf zirkulierende Teilstrom der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion zusätzlich einer dritten Entspannungsstufe zugeführt wird, wobei diese der vorbeschriebenen zweistufigen Entspannung vorgeschaltet ist,
- – die verflüssigte Kohlenwasserstoff-reiche Fraktion entspannt und die bei dieser Entspannung anfallende gasförmige Fraktion abgetrennt und erneut der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion zugemischt wird, wobei die gasförmige Fraktion vor der Zumischung ggf. verdichtet wird, und
- – sofern die zu verflüssigende, Kohlenwasserstoff-reiche Fraktion und/oder wenigstens ein anderer Verfahrensstrom einer Verdichtung unterworfen wird, wenigstens eine der Entspannungsstufen und die oder wenigstens eine der Verdichtungen in einem Compander realisiert werden.
- The partial flow of the hydrocarbon-rich fraction to be liquefied in the open expander refrigeration cycle is additionally fed to a third expansion stage, which precedes the two-stage expansion described above,
- - The liquefied hydrocarbon-rich fraction is expanded and the gaseous fraction resulting from this expansion separated and re-admixed to be liquefied hydrocarbon-rich fraction, wherein the gaseous fraction is optionally compressed before admixture, and
- - If the liquefied, hydrocarbon-rich fraction and / or at least one other process stream is subjected to a compression, at least one of the expansion stages and the or at least one of the densifications are realized in a Compander.
Erfindungsgemäß wird der in dem offenen Expander-Kältekreislauf zirkulierende Teilstrom der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion nunmehr wenigstens zweistufig entspannt. Mittels dieser Verfahrensweise lässt sich der Wirkungsgrad des Verflüssigungsprozesses bereits wesentlich verbessern. Beim Übergang von einer ein- zu einer zweistufigen Entspannung verringert sich der Energieverbrauch um ca. 20%. Wird zusätzlich eine dritte Entspannungsstufe vorgesehen, verringert sich der Energieverbrauch im Vergleich zu einer einstufigen Entspannung um ca. 25%.According to the invention, the partial stream of the hydrocarbon-rich fraction to be liquefied circulating in the open expander refrigeration cycle is now at least two-stage depressurized. By means of this procedure, the efficiency of the liquefaction process can already be substantially improved. When moving from one to two-stage relaxation, energy consumption decreases by about 20%. If a third expansion stage is additionally provided, the energy consumption is reduced by approx. 25% compared to a single-stage relaxation.
Es ist offensichtlich, dass der apparative Aufwand des erfindungsgemäßen Verfahrens im Vergleich zu einem Verflüssigungsprozess, bei dem eine lediglich einstufige arbeitsleistende Entspannung erfolgt, größer ist. Dieser negative Aspekt wird jedoch durch die mit dem erfindungsgemäßen Verfahren verbundenen Vorteile kompensiert.It is obvious that the expenditure on equipment of the method according to the invention is greater in comparison with a liquefaction process in which a one-stage work-performing expansion takes place. However, this negative aspect is compensated by the advantages associated with the method according to the invention.

In vorteilhafter Weise können die dargestellten Verdichter und Entspannungsstufen in einem oder mehreren sog. Compandern auf unterschiedlichste Weise miteinander kombiniert werden. Bei einem Compander sind die Verdichtereinheit(en) sowie die. Expandereinheit(en) über ein gemeinsames Getriebe auf derselben Welle verbunden. Damit kann der apparative Aufwand des erfindungsgemäßen Verfahrens wesentlich reduziert werden.Advantageously, the compressors and expansion stages shown can be combined with one another in one or more so-called companders in a very wide variety of ways. In a compander, the compressor unit (s) and the. Expander unit (s) connected via a common gear on the same shaft. Thus, the expenditure on equipment of the method according to the invention can be substantially reduced.
Eine weitere Möglichkeit besteht darin, einen Kreislaufverdichter vorzusehen, der einen externen Antrieb – bspw. einen E-Motor aufweist –, und dass jeder der Expander einen auf der gleichen Welle sitzenden Blower antreibt.Another possibility is to provide a cycle compressor having an external drive - eg an electric motor - and that each of the expander drives a blower seated on the same shaft.
