Abstract
Es wird ein Verfahren zum Verflüssigen einer kohlenwasserstoffreichen Fraktion unter gleichzeitiger Abtrennung einer C-reichen Fraktion beschrieben, wobei die Abkühlung und Verflüssigung der kohlenwasserstoffreichen Fraktion im indirekten Wärmetausch gegen das Kältemittelgemisch eines Kältemittelgemischkreislaufes, in dem das Kältemittelgemisch wenigstens zweistufig verdichtet wird, und die Abtrennung der C-reichen Fraktion auf einem einstellbaren Temperaturniveau erfolgt, wobei das Kältemittelgemisch in eine gasförmige und eine flüssige Fraktion aufgetrennt wird, beide Fraktionen unterkühlt, im Wesentlichen auf den Saugdruck der ersten Verdichterstufe entspannt und zumindest teilverdampft werden. Erfindungsgemäß wird zumindest zeitweilig wenigstens ein Teilstrom (19, 24) der verflüssigten, vormals gasförmigen Fraktion des Kältemittelgemisches (15) entspannt (j, h) und der entspannten Flüssigfraktion des Kältemittelgemisches (21) zugemischt.The invention relates to a process for liquefying a hydrocarbon-rich fraction with simultaneous removal of a C-rich fraction, wherein the cooling and liquefaction of the hydrocarbon-rich fraction in indirect heat exchange against the refrigerant mixture of a mixed refrigerant cycle in which the refrigerant mixture is at least two-stage densified, and the separation of the C -rich fraction takes place at an adjustable temperature level, wherein the refrigerant mixture is separated into a gaseous fraction and a liquid fraction, both fractions are undercooled, substantially relaxed to the suction pressure of the first compressor stage and at least partially vaporized. According to the invention, at least temporarily, at least one partial flow (19, 24) of the liquefied, formerly gaseous fraction of the refrigerant mixture (15) is expanded (j, h) and admixed with the expanded liquid fraction of the refrigerant mixture (21).
Description
Die Erfindung betrifft ein Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion unter gleichzeitiger Abtrennung einer C2+-reichen Fraktion, wobei die Abkühlung und Verflüssigung der Kohlenwasserstoff-reichen Fraktion im indirekten Wärmetausch gegen das Kältemittelgemisch eines Kältemittelgemischkreislaufes, in dem das Kältemittelgemisch wenigstens zweistufig verdichtet wird, und die Abtrennung der C2+-reichen Fraktion auf einem einstellbaren Temperaturniveau erfolgt, wobei das Kältemittelgemisch in eine gasförmige und eine flüssige Fraktion aufgetrennt wird, beide Fraktionen unterkühlt, im Wesentlichen auf den Saugdruck der ersten Verdichterstufe entspannt und zumindest teilverdampft werden.The invention relates to a method for liquefying a hydrocarbon-rich fraction while simultaneously separating a C 2+ -rich fraction, wherein the cooling and liquefaction of the hydrocarbon-rich fraction in the indirect heat exchange with the refrigerant mixture of a mixed refrigerant cycle, in which the refrigerant mixture is compressed at least two stages , And the separation of the C 2+ -rich fraction is carried out at an adjustable temperature level, wherein the refrigerant mixture is separated into a gaseous and a liquid fraction, supercooling both fractions, substantially relaxed to the suction pressure of the first compressor stage and at least partially evaporated.

der
Bei Erdgasverflüssigungsprozessen kleiner bis mittlerer Kapazität – darunter seien Produktionsraten von 30.000 bis 1 Mio. jato LNG zu verstehen – kommen oftmals Gemischkreisläufe mit lediglich einem Kreislaufverdichter – diese werden auch als SMR(Single Mixed Refrigerant)-Prozesse bezeichnet – zur Anwendung. Diese haben den Nachteil, dass die flüssige Kältemittelphase lediglich bei einem Druckniveau verdampft werden kann. Das gezielte Einstellen und Regeln eines gewünschten Temperaturprofils ist folglich schwierig, da die Zahl der Eingriffsmöglichkeiten bzw. Freiheitsgrade bei derartigen Prozessen beschränkt ist. Entsprechende Temperaturprofile sind beispielsweise erforderlich, um die Teilkondensation der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion exakt bis zu einer bestimmten Temperatur voranzutreiben, die für die angestrebte Abtrennung der unerwünschten Komponenten benötigt wird.at Natural gas liquefaction processes of small to medium capacity - including Production rates of 30,000 to 1 million tonnes of LNG are to be understood often mixture cycles with only one cycle compressor - this are also referred to as SMR (Single Mixed Refrigerant) processes - for Application. These have the disadvantage that the liquid Refrigerant phase evaporated only at a pressure level can be. The targeted setting and regulation of a desired Temperature profiles is therefore difficult, since the number of intervention options or degrees of freedom in such processes limited is. Corresponding temperature profiles are required, for example, to the partial condensation of the liquefied hydrocarbons rich Fraction to drive exactly up to a certain temperature, for the desired separation of the unwanted Components is needed.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion unter gleichzeitiger Abtrennung einer C2+-reichen Fraktion anzugeben, das die vorbeschriebenen Nachteile vermeidet. Insbesondere soll ein gattungsgemäßes Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion angegeben werden, das zum einen robust ist und zum anderen eine effiziente und kontrollierbare Abtrennung von Ethan und höheren Kohlenwasserstoffen im Zuge eines Erdgasverflüssigungsprozesses ermöglicht. Daher ist der Verdampfungsverlauf eines Kältemittelgemischstroms so zu gestalten, dass dieser unmittelbar zur Regelung einer Abtrennung von Ethan und höheren Kohlenwasserstoffen eingesetzt werden kann.Object of the present invention is to provide a generic method for liquefying a hydrocarbon-rich fraction with simultaneous separation of a C 2+ -rich fraction, which avoids the disadvantages described above. In particular, a generic method for liquefying a hydrocarbon-rich fraction is given, which is both robust and on the other hand allows an efficient and controllable separation of ethane and higher hydrocarbons in the course of a natural gas liquefaction process. Therefore, the course of evaporation of a mixed refrigerant stream is to be designed so that it can be used directly to control a separation of ethane and higher hydrocarbons.
Zur Lösung dieser Aufgabe wird ein gattungsgemäßes Verfahren zum Verflüssigen einer Kohlenwasserstoff-reichen Fraktion unter gleichzeitiger Abtrennung einer C2+-reichen Fraktion vorgeschlagen, das dadurch gekennzeichnet ist, dass zumindest zeitweilig wenigstens ein Teilstrom der verflüssigten, vormals gasförmigen Fraktion des Kältemittelgemisches entspannt und der entspannten Flüssigfraktion des Kältemittelgemisches zugemischt wird.To solve this problem, a generic method for liquefying a hydrocarbon-rich fraction with simultaneous removal of a C 2+ -rich fraction is proposed, which is characterized in that at least temporarily relaxes at least a partial stream of the liquefied, formerly gaseous fraction of the refrigerant mixture and the relaxed Liquid fraction of the refrigerant mixture is mixed.
Mittels einer Variation der Mengenverhältnisse der flüssigen Fraktion und der verflüssigten, vormals gasförmigen Fraktion kann das Temperaturprofil während der Verdampfung des aus den beiden vorgenannten Fraktionen gemischten Kältemittels derart beeinflusst werden, dass aufgabengemäß die Temperatur des gemischten Kältemittels im oberen Bereich des- bzw. derjenigen Wärmetauscher, die der Abkühlung und Teilkondensation der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion dienen, immer unter der Temperatur der zu verflüssigenden Fraktion liegt. Die erfindungsgemäße Verfahrensweise ermöglicht eine hinreichende Regelbarkeit der Temperatur der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion beim Eintritt in die für die Abtrennung der C2+-reichen Fraktion vorzusehende Abtrennvorrichtung bzw. Trennkolonne, so dass die Einstellung einer gewünschten Konzentration der C2+-Kohlenwasserstoffe im Verflüssigungsprodukt bzw. LNG (Liquefied Natural Gas) möglich ist.By means of a variation of the proportions of the liquid fraction and the liquefied, formerly gaseous fraction, the temperature profile during the evaporation of the refrigerant mixed from the two aforementioned fractions can be influenced in such a way that, according to the task, the temperature of the mixed refrigerant in the upper region of the respective heat exchanger, which serve to cool and partially condense the hydrocarbon-rich fraction to be liquefied, always below the temperature of the fraction to be liquefied.

Der Kältemittelgemischkreislauf besteht aus einer zweistufigen Verdichtereinheit, bestehend aus einer ersten und einer zweiten Verdichterstufe C1 bzw. C2. Den beiden Verdichterstufen ist jeweils ein Kühler E1 bzw. E2 nachgeschaltet. Des Weiteren sind ein Niederdruck-Abscheider D1, ein Mitteldruck-Abscheider D2 sowie ein Hochdruck-Abscheider D3 vorgesehen.Of the Refrigerant mixture cycle consists of a two-stage Compressor unit, consisting of a first and a second Compressor stage C1 or C2.

In den Ventilen f und g erfolgt üblicherweise eine Entspannung auf einen Druck, der bis auf unvermeidliche Druckabfälle dem Saugdruck der ersten Verdichterstufe C1 entspricht. Durch die geeignete Wahl der Zusammensetzung, Menge und/oder des Verdampfungsdruckes des Kältemittelgemisches können sowohl die Endtemperatur als auch der Mengenstrom der zu verflüssigenden Kohlenwasserstoff-reichen Fraktion bzw. des zu verflüssigenden Erdgasstromes eingestellt werden.In The valves f and g is usually a relaxation at a pressure that goes up to unavoidable pressure drops corresponds to the suction pressure of the first compressor stage C1.

Die Zusammensetzungen der gasförmigen und flüssigen Kältemittelfraktionen wiederum sind durch die Gleichgewichte in den Abscheidern D2 und D3 gekoppelt. Daher kann die Ventilstellung des Ventils f nicht in ausreichendem Maße das Temperaturprofil im oberen bzw. wärmeren Teil des Wärmetauschers E3 beeinflussen.by virtue of the above-described relaxation of the liquid supercooled and the liquefied, formerly gaseous fraction of the refrigerant mixture in the valves f and g on a Essentially identical evaporation pressure is the temperature profile the refrigerant flow in the heat exchanger E3 downstream of the valve f not freely selectable. The compositions the gaseous and liquid refrigerant fractions in turn are due to the equilibria in the separators D2 and D3 coupled. Therefore, the valve position of the valve f can not sufficiently the temperature profile in the upper or affect warmer part of the heat exchanger E3.
