Description
Die Erfindung betrifft ein Verfahren zur Abtrennung von leichtsiedenden Komponenten aus einem Kohlenwasserstoffstrom, insbesondere zur Abtrennung einer C2-Fraktion von einer C3+-Fraktion, aber auch anderen Trennaufgaben im C1 bis C4-Bereich.The invention relates to a process for the separation of low-boiling components from a hydrocarbon stream, in particular for the separation of a C 2 fraction from a C 3 + fraction, but also other separation tasks in the C 1 to C 4 range.
Üblicherweise wird eine solche Abtrennung mittels einer Kombination aus einer sogenannten „Coldbox" und einer Destillationskolonne durchgeführt. Die Destillationskolonne wird als Deethanizer betrieben und aus so bezeichnet, da alle Stoffe, die leichter als Propylen sieden, in diesem Deethanizer über Kopf abgetrennt werden.Usually Such a separation by means of a combination of so-called "cold box" and a distillation column carried out. The distillation column is operated as a deethanizer and off so called because all substances that boil lighter than propylene, in this deethanizer over Head to be separated.
Die Coldbox hat die Aufgabe, das Einsatzgemisch zunächst auf –25°C abzukühlen, wobei das dabei entstehende Kondensat direkt in den Deethanizer geleitet wird. Das nicht kondensierte Gas wird weiter auf –90°C abgekühlt, wobei das dabei entstehende produktreiche Kondensat nach Wärmetausch ebenfalls zum Deethanizer geführt wird.The Coldbox has the task of initially cooling the feed mixture to -25 ° C, wherein the resulting Condensate is passed directly into the deethanizer. The uncondensed Gas is further cooled to -90 ° C, where the resulting product-rich condensate after heat exchange also led to the deethanizer becomes.
Die restliche Gasphase, die im wesentlichen unkondensierbaren Wasserstoff enthält, wird, nach Wärmetausch in dem in die Coldbox eintretenden Strom, entspannt. Aufgrund des Joule-Thompson-Effekts kühlen sich die Leichtsieder dabei auf –110°C ab. Dieses Temperaturniveau wird dazu benutzt, den in die Coldbox eintretenden Strom zum Teil zu kondensieren. Die nicht auskondensierten Leichtsieder sind im wesentlichen frei von C3+-Komponenten.The residual gas phase, which is essentially non-condensable hydrogen contains will, after heat exchange in the stream entering the coldbox, relaxes. Due to the Cool Joule-Thompson effect The low boilers thereby at -110 ° C from. This temperature level is used to part of the current entering the coldbox to condense. The non-condensed low boilers are in essentially free of C3 + components.
Alle produktreichen Kondensatphase werden schließlich in den Deethanizer geführt, in der die übrigen Leitchtlieder von den schwerer siedenden Komponenten abgetrennt werden. Hierzu ist eine Temperatur von –20°C am Kopf der Kolonne erforderlich.All Product rich condensate phase are finally led into the deethanizer, in the rest Leitchtlieder separated from the heavier boiling components become. For this purpose, a temperature of -20 ° C at the top of the column is required.
Als Kühlmittel für die Abkühlung des Einsatzgemisches vor der Coldbox, für den Betrieb der Coldbox und zur Kühlung des Deethanizers wird verdampfendes Propan bei –30°C verwendet, das mittels einer mit Ammoniak betriebenen Kälteanlage auf dieser Temperatur gehalten wird.When coolant for the Cooling the feed mixture before the coldbox, for the operation of the coldbox and for cooling the deethanizer is used evaporating propane at -30 ° C, which by means of a with ammonia operated refrigeration system is kept at this temperature.
Die Erzeugung der Kälte für ein derartiges Verfahren ist äußerst aufwendig. Die Aufgabe der Erfindung ist es daher, ein Verfahren und eine Vorrichtung zur Verfügung zu stellen, bei welchem der Kälteverbrauch erheblich reduziert werden kann.The Generation of the cold for a Such method is extremely expensive. The object of the invention is therefore a method and a device to disposal to put at which the refrigeration consumption can be significantly reduced.

Was also bisher in 2 Prozessschritten erreicht wurde, läßt sich mithilfe der Erfindung nunmehr in einem Schritt ohne vorgeschaltete Coldbox realisieren, was ein Vorteil der Erfindung ist.What so far has been achieved in 2 process steps, can be with the invention now in one step without upstream Coldbox realize what an advantage of the invention.
Durch die verfahrensgemäße Nutzung der Destillationvorrichtung mit mehreren bei unterschiedlichen Temperaturniveaus arbeitenden Kondensatoren wird erreicht, dass nicht die gesamte Kühlmenge für die Kondensation auf dem niedrigsten Temperaturniveau bereitgestellt werden muss. Stattdessen arbeiten die Zwischenkondensatoren bei Temperaturen von +18°C beziehungsweise –34°C, was ein weiterer Vorteil der Erfindung ist.By the procedural use the distillation device with several at different temperature levels working capacitors is achieved that not the entire Cooling amount for the condensation must be provided at the lowest temperature level. Instead, the intermediate capacitors work at temperatures from + 18 ° C respectively -34 ° C, what a Another advantage of the invention.
Der größte Teil der in der Kolonne, sofern eine solche verwendet wird, aufsteigenden Dämpfe wird daher schon vor Erreichen des Kolonnenkopfkondensators kondensiert und strömt als Flüssigkeit nach untenr. Das für den Betrieb des Kopfkondensators benötigte Kälteniveau, ca. –90°C, und die benötigte Kondensationsleistung können durch Entspannung der Leichtsieder in der Anlage selbst erzeugt werden, was ein weiterer Vorteil der Erfindung ist.Of the biggest part in the column, if used, rising Vapors will therefore already condensed before reaching the column top condenser and flows as a liquid after untenr. That for cooling level needed, the operation of the top condenser, about -90 ° C, and the needed Condensation performance can be generated by relaxing the low boilers in the plant itself, which is another advantage of the invention.
Die Erfindung wird im Folgenden anhand von 3 Beispielen näher erläutert:The The invention is explained in more detail below with reference to three examples:

Diese letzte Variante hat gegenüber den vorangegangen den Vorteil, dass nur der Oberteil der zweiten Auftriebskolonne Tieftemperatur-bständig ausgeführt und mit einer stärkeren Isolierung ausgestattet werden muss, um Wärmeaufnahme zu verhindern, was ein Vorteil der Erfindung ist.These last variant has opposite preceded by the advantage that only the upper part of the second Buoyancy column carried out at low temperature and with a stronger insulation must be equipped to absorb heat to prevent what is an advantage of the invention.
In allen 3 Beispielen wird zwar eine größere Wärmemenge zum Betrieb der Verdampfer gegenüber dem herkömmlichen Stand der Technik benötigt, diese Wärme ist jedoch nur bei ca. 71°C erforderlich, weswegen in der Regel Abfallwärme aus anderen Prozessteilen eines Anlagenverbundes zum Einsatz kommen wird, welche sonst aufwändig mittels Luftkühlern abgeführt werden müsste, was ein weiterer Vorteil der Erfindung ist.In Although all three examples, a larger amount of heat to operate the evaporator across from the conventional one Prior art needed this Heat is but only at about 71 ° C required, which is why waste heat from other parts of the process usually a plant network will be used, which otherwise consuming by means of air coolers dissipated would have to which is another advantage of the invention.

Vorteile des erfindungsgemäßen Verfahrens
gegenüber
dem eingangs aufgezeigten Verfahren nach dem Stand der Technik sind:
Durch
den Einsatz von Kühlwasser
können
ca. 25% der Ammoniakkühlleistung
eingespart werden, daher ist auch nur eine kleinere Ammoniakkühlanlage
erforderlich Die Propankühlleistung
