Abstract
Es wird ein Verfahren zum Abkühlen eines ein- oder mehrkomponentigen Stromes, insbesondere einer Kohlenwasserstoffreichen Fraktion, durch indirekten Wärmetausch mit dem Kältemittelgemisch eines Kältemittelgemischkreislaufes beschrieben, wobei das Kältemittelgemisch wenigstens zweistufig verdichtet wird und in eine tiefersiedende, auf den Enddruck des Kältemittelgemischkreislaufes verdichtete Kältemittelgemischfraktion und in wenigstens eine höhersiedende, auf einen Zwischendruck verdichtete Kältemittelgemischfraktion aufgetrennt wird. Erfindungsgemäß wir die höhersiedende Kältemittelgemischfraktion (5) auf den Druck der tiefersiedenden Kältemittelgemischfraktion (8) gepumpt (P11) und vor dem oder unmittelbar zu Beginn des indirekten Wärmetausches (E1) mit der tiefersiedenden Kältemittelgemischfraktion (8) vereinigt.It is a method for cooling a one- or multi-component stream, in particular a hydrocarbon-rich fraction described by indirect heat exchange with the refrigerant mixture of a mixed refrigerant cycle, wherein the refrigerant mixture is compressed at least two stages and in a lower boiling, compressed to the final pressure of the refrigerant mixture cycle refrigerant mixture fraction and in at least a higher boiling, compressed to an intermediate pressure refrigerant mixture fraction is separated. According to the invention, the higher boiling refrigerant mixture fraction (5) is pumped (P11) to the pressure of the lower boiling refrigerant mixture fraction (8) and combined with the lower boiling refrigerant mixture fraction (8) before or immediately at the beginning of the indirect heat exchange (E1).
Description
Die Erfindung betrifft ein Verfahren zum Abkühlen eines ein- oder mehrkomponentigen Stromes, insbesondere einer Kohlenwasserstoffreichen Fraktion, durch indirekten Wärmetausch mit dem Kältemittelgemisch eines Kältemittelgemischkreislaufes, wobei das Kältemittelgemisch wenigstens zweistufig verdichtet wird und in eine tiefersiedende, auf den Enddruck des Kältemittelgemischkreislaufes verdichtete Kältemittelgemischfraktion und in wenigstens eine höhersiedende, auf einen Zwischendruck verdichtete Kältemittelgemischfraktion aufgetrennt wird.The invention relates to a method for cooling a one- or multi-component stream, in particular a hydrocarbon-rich fraction, by indirect heat exchange with the refrigerant mixture of a mixed refrigerant cycle, wherein the refrigerant mixture is compressed at least two stages and in a lower-boiling, compressed to the final pressure of the refrigerant mixture cycle refrigerant mixture fraction and in at least a higher boiling, compressed to an intermediate pressure refrigerant mixture fraction is separated.
Ein gattungsgemäßes Verfahren zum Abkühlen eines ein- oder mehrkomponentigen Stromes ist beispielsweise aus der
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Verfahren zum Abkühlen eines ein- oder mehrkomponentigen Stromes, das insbesondere für die Verflüssigung eines Kohlenwasserstoffreichen Stromes geeignet ist, anzugeben, das einen geringeren apparativen und/oder regeltechnischen Aufwand erfordert.Object of the present invention is to provide a generic method for cooling a single- or multi-component stream, which is particularly suitable for the liquefaction of a hydrocarbon-rich stream to specify, which requires a smaller apparatus and / or regulatory technical effort.
Zur Lösung dieser Aufgabe wird ein gattungsgemäßes Verfahren zum Abkühlen eines ein- oder mehrkomponentigen Stromes vorgeschlagen, das dadurch gekennzeichnet ist, dass die höhersiedende Kältemittelgemischfraktion auf den Druck der tiefersiedenden Kältemittelgemischfraktion gepumpt und vor dem oder unmittelbar zu Beginn des indirekten Wärmetausches mit der tiefersiedenden Kältemittelgemischfraktion vereinigt wird.To solve this problem, a generic method for cooling a one- or multi-component stream is proposed, which is characterized in that the higher-boiling refrigerant mixture fraction is pumped to the pressure of the lower boiling refrigerant mixture fraction and combined before or immediately at the beginning of the indirect heat exchange with the lower boiling refrigerant mixture fraction ,
Aufgrund der erfindungsgemäß vorzusehenden Zusammenführung der höhersiedenden sowie der tiefersiedenden Kältemittelgemischfraktion können der apparative sowie der regeltechnische Aufwand verringert werden. Dabei kommt es jedoch zu keiner Erhöhung des Energieverbrauchs des Kältemittelgemischkreislaufes Zusätzliche Investitions- sowie Betriebskosten werden durch die zusätzlich vorzusehende Pumpe verursacht, mittels derer die höhersiedende Kältemittelgemischfraktion auf den Druck der tiefersiedenden Kältemittelgemischfraktion gepumpt wird.Because of the combination of the higher-boiling and the lower-boiling mixed refrigerant fractions to be provided according to the invention, the apparatus and the technical control effort can be reduced. However, there is no increase in the energy consumption of the mixed refrigerant cycle. Additional investment and operating costs are caused by the additionally provided pump, by means of which the higher-boiling refrigerant mixture fraction is pumped to the pressure of the lower-boiling refrigerant mixture fraction.
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens zum Abkühlen eines ein- oder mehrkomponentigen Stromes, die Gegenstände der abhängigen Patentansprüche darstellen, sind dadurch gekennzeichnet, dass
- – das Pumpen der höhersiedende Kältemittelgemischfraktion ein- oder mehrstufig erfolgt, und
- – die Vereinigung bzw. Vermischung der höhersiedenden und der tiefersiedenden Kältemittelgemischfraktion in einem speziell dafür ausgebildeten Bereich des Wärmetauschers erfolgt.
- - The pumping of the higher-boiling refrigerant mixture fraction takes place in one or more stages, and
- The combination or mixing of the higher-boiling and the lower-boiling refrigerant mixture fraction takes place in a specially designed region of the heat exchanger.
Das erfindungsgemäße Verfahren zum Abkühlen eines ein- oder mehrkomponentigen Stromes sowie weitere vorteilhafte Ausgestaltungen desselben seien nachfolgend anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The inventive method for cooling a one-component or multi-component stream and further advantageous embodiments thereof are explained in more detail below with reference to the embodiment shown in the figure.
Die Figur zeigt ein Verfahren zum Abkühlen und Verflüssigen einer Kohlenwasserstoffreichen, Stickstoffenthaltenden Einsatzfraktion, bei dem die Gewinnung einer hochkonzentrierten Stickstofffraktion in den Verflüssigungsprozess integriert ist.

Die vorbeschriebene Verfahrensführung kommt insbesondere dann zur Anwendung, wenn die Stickstoffkonzentration im Endprodukt LNG auf 1 Vol.-% zu begrenzen ist. Im Falle einer höheren Stickstoff-Konzentration könnte es ansonsten innerhalb des LNG-Lagertanks zu unerwünschten und gefährlichen Schichtungen aufgrund unterschiedlicher Dichten kommen.The method described above is used in particular when the nitrogen concentration in the end product LNG is to be limited to 1% by volume. Otherwise, in the case of a higher nitrogen concentration, unwanted and dangerous stratifications due to different densities could occur within the LNG storage tank.
