Description

Die Erfindung betrifft eine Verdichtungsanlage, insbesondere zur Gasverflüssigung, mit zumindest einer Gasturbine, welche einen Gasturbinenverdichter umfasst, und mit einer Dampfturbine, wobei eine der Gasturbine zugeordnete Dampferzeugungsanlage mit Abgasen der Gasturbine betrieben wird, so dass der in der Dampferzeugungsanlage erzeugte Dampf die Dampfturbine antreibt, wobei der Kombination aus Gasturbine und der Dampfturbine mindestens ein zusätzlicher Verdichter zur Verdichtung eines Prozessmediums zugeordnet ist, der direkt mit der Gasturbine und/oder der Dampfturbine verbunden ist, so dass der zugeordnete Verdichter jeweils direkt von der Gasturbine und/oder der Dampfturbine antreibbar ist.The invention relates to a compression plant, in particular for gas liquefaction, with at least one gas turbine, which comprises a gas turbine compressor, and with a steam turbine, wherein a gas turbine associated steam generating plant is operated with exhaust gases of the gas turbine, so that the steam generated in the steam generating plant drives the steam turbine, wherein the combination of the gas turbine and the steam turbine is associated with at least one additional compressor for compressing a process medium, which is connected directly to the gas turbine and / or the steam turbine, so that the associated compressor can be driven directly from the gas turbine and / or the steam turbine.

Bekannt ist, entweder Gasturbinen oder Dampfturbinen beispielsweise zur Stromerzeugung für elektrische Antriebsmaschinen bzw. Elektromotoren für den Antrieb von Kompressoren bzw. Verdichtern einzusetzen. Nachteilig bei dem bekannten Stand der Technik ist, dass sich der Gesamtwirkungsgrad der Anlagen auf die Möglichkeiten des Einzelprozesses beschränkt. Dabei liegen die Wirkungsgrade von Gasturbinen etwa bei 40%, von Dampfturbinen etwa bei 45% und von elektrischen Arbeitsmaschinen (z.B. Elektromotoren) etwa bei 98%. Bei den elektrischen Arbeitsmaschinen bzw. den Elektromotoren ist allerdings zu berücksichtigen, dass der Strom, den diese benötigen von einem Gasprozess (Gasturbine), einem Dampfprozess (Dampfturbine) oder durch eine Kombination beider Prozesse bereitgestellt werden muss. Der Wirkungsgrad für die Stromerzeugung kann dabei mit der heutigen Technik maximal 60% betragen. Weiter ist eine komplizierte Schaltungstechnik erforderlich, um den erzeugten elektrischen Strom zur elektrischen Arbeitsmaschine bzw. zum Elektromotor zu übertragen. Weiter sind übertragungsverluste bei einem System, das elektrische Energie in einem Frequenzumrichter von einem Frequenzbereich in einen anderen umzusetzen hat ebenfalls nicht vernachlässigbar. Die Übertragungsverluste können beispielsweise bis zu etwa 5% betragen.It is known to use either gas turbines or steam turbines, for example, to generate electricity for electric drive machines or electric motors for the drive of compressors or compressors. A disadvantage of the known state of the art is that the overall efficiency of the systems is limited to the possibilities of the individual process. The efficiencies of gas turbines are about 40%, of steam turbines about 45% and of electrical machines (eg electric motors) about 98%. In the case of electric machines or electric motors, however, it must be taken into consideration that the power they require must be provided by a gas process (gas turbine), a steam process (steam turbine) or by a combination of both processes. The efficiency for power generation can amount to a maximum of 60% with today's technology. Next, a complicated circuit technology is required to transmit the generated electric power to the electric machine or to the electric motor. Further, transmission losses in a system are the electrical energy in a frequency converter from one frequency range to another has also not negligible. The transmission losses may be, for example, up to about 5%.

Die elektrischen Arbeitsmaschinen bzw. die Elektromotoren treiben beispielsweise einen Verdichter an, der z.B. als Verdichter einer Gasverflüssigungsanlage einsetzbar ist. Eine solche Gasverflüssigungsanlage ist z.B. als LNG-Anlage (Liquified Natural Gas) bekannt. Hierbei wird Erdgas bis auf ca. -160°C abgekühlt. Dabei wird das Erdgas flüssig und ist (kleineres Volumen) dann auch leichter zu transportieren (üblicherweise in speziellen Transportvorrichtungen). Die Verdichter haben dabei die Aufgabe Betriebsmedien, üblicherweise Betriebsgase zu verdichten, die bei einer späteren Expansion Wärme aufnehmen können. Diese Wärme wird dem Erdgas in der so genannten "Cold Box" der LNG-Anlage entzogen, und das Erdgas auf diese Weise abgekühlt. Das Betriebsmedium bzw. Betriebsgas wird dabei in einem Kreislauf immer wieder verdichtet und entspannt.For example, the electric machines or electric motors drive a compressor, e.g. can be used as a compressor of a gas liquefaction plant. Such a gas liquefaction plant is e.g. known as LNG plant (Liquefied Natural Gas). Here, natural gas is cooled down to about -160 ° C. The natural gas becomes liquid and is then (smaller volume) also easier to transport (usually in special transport devices). The compressors have the task of operating media, usually compress operating gases that can absorb heat during a later expansion. This heat is extracted from the natural gas in the so-called "cold box" of the LNG plant, and the natural gas is cooled in this way. The operating medium or operating gas is compressed and relaxed again and again in a cycle.

Die Verdichter werden üblicherweise von dem o.g. Elektromotor angetrieben, so dass hier erhebliche (Übertragungs) Verluste entstehen, da der für den Elektromotor zu erzeugende Strom entweder von dem Gasprozess oder dem Dampfprozess erzeugt wird, und da der Elektromotor den Verdichter antreiben muss.The compressors are usually supplied by the o.g. Driven electric motor, so that there are significant (transmission) losses, since the electricity to be generated for the electric motor is generated either by the gas process or the steam process, and because the electric motor must drive the compressor.

Aus der DE 21 02 770 , der US 4,321,790 und der WO 2005/024188 A2 sind jeweils kombinierte Gas- und Dampfturbinenanlagen bekannt, welche auch zum Antrieb eines Verdichters vorgesehen sind. Die beschriebenen Anlagen haben insbesondere im Schwankungsbetrieb signifikante Wirkungsgradeinbußen.From the DE 21 02 770 , of the US 4,321,790 and the WO 2005/024188 A2 combined gas and steam turbine plants are known, which are also provided to drive a compressor. The plants described have significant losses of efficiency, especially in the fluctuation mode.

Der Erfindung liegt die Aufgabe zugrunde eine Verdichtungsanlage der Eingangs genannten Art mit einfachen Mitteln dahingehend zu verbessern, dass der Wirkungsgrad verbessert und gleichzeitig schädliche Emissionen reduziert werden.The invention has the object to improve a compacting system of the type mentioned by simple means to the effect that the efficiency is improved while harmful emissions are reduced.

Erfindungsgemäß wird die Aufgabe durch eine Verdichtungsanlage mit den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a compression system with the features of claim 1.

Vorteilhaft werden Gasturbinen und Dampfturbinen jeweils separat dazu benutzt jeweils den zumindest einen Verdichter direkt anzutreiben, also ohne Zwischenschaltung einer elektrischen Arbeitsmaschine bzw. eines Elektromotors. Dies führt zu einer Wirkungsgradverbesserung, da die Energieübertragung sowohl von der Gasturbine als auch der Dampfturbine zu dem jeweils zugeordneten zumindest einen Verdichter auf direktem Wege erfolgt, und so Umwandlungsverluste, wie sie bei der Erzeugung von Strom und Antrieb von Verdichtern mittels elektrischer Arbeitsmaschinen bzw. Elektromotoren auftritt, zu vermeiden. Damit wird aber auch gleichzeitig eine Reduzierung schädlicher Emissionen wie z.B. -CO2-Emissionen erreicht, was insbesondere in Hinsicht auf den Handel bzw. den Erwerb von Emissionsrechten vorteilhaft ist. Denn wer weniger Emissionen ausstößt, muss auch weniger Emissionsrechte erwerben.Advantageously, gas turbines and steam turbines are each used separately to each drive the at least one compressor directly, so without the interposition of an electrical machine or an electric motor. This leads to an improvement in efficiency, since the energy transfer takes place both from the gas turbine and the steam turbine to the associated at least one compressor directly, and thus conversion losses, as in the generation of electricity and drive of compressors by electric machines or electric motors occurs, avoid. At the same time, however, a reduction of harmful emissions such as CO 2 emissions is achieved, which is particularly true with regard to trade and the acquisition of emission rights is advantageous. Because who emits less emissions, must also acquire fewer emission rights.

Dies ist umso vorteilhafter, als das Abgas der Gasturbine dazu verwendet werden kann eine Dampferzeugungsanlage, bevorzugt einen Abhitzekessel zu befeuern, der wiederum den für die Dampfturbine benötigten Dampf erzeugt. Insofern ist es zweckmäßig im Sinne der Erfindung, wenn die Gasturbine und die Dampfturbine miteinander zu einem Gas- und Dampfprozess (GuD-Prozess) kombiniert werden. Natürlich können mehrere Gasturbinen an einen Abhitzekessel angeschlossen sein, wobei dann zweckmäßiger Weise auch jede Gasturbine jeweils zumindest einen Verdichter direkt antreibt. Die Dampfturbine kann einen Hochdruckteil, einen Mitteldruckteil und/oder einen Niederdruckteil aufweisen, wobei bevorzugt eine Dampfturbine mit allen drei oben genannten Druckteilen vorgesehen ist. Aus dem Abhitzekessel gelangt dabei der Dampf beispielhaft zunächst in den Hochdruckteil, von dort in den Mitteldruckteil und anschließend in den Niederdruckteil, hinter dem der zumindest eine Verdichter angeordnet ist. Natürlich ist die Anordnung des Verdichters hinter dem Niederdruckteil nicht auf diese Anordnung beschränkt. Möglich ist, dass der Verdichter beispielsweise zwischen den Teilturbinen oder auf der Hochdruckseite angeordnet ist.This is all the more advantageous as the exhaust gas of the gas turbine can be used to a steam generating plant, preferably to fire a waste heat boiler, which in turn generates the steam required for the steam turbine. In this respect, it is expedient for the purposes of the invention, when the gas turbine and the steam turbine are combined with each other to a gas and steam process (gas and steam process). Of course, several gas turbines may be connected to a waste heat boiler, then expediently each gas turbine drives at least one compressor directly. The steam turbine can have a high-pressure part, a medium-pressure part and / or a low-pressure part, wherein a steam turbine with all three above-mentioned pressure parts is preferably provided. From the waste heat boiler, the steam passes, for example, first into the high-pressure part, from there into the medium-pressure part and then into the low-pressure part, behind which the at least one compressor is arranged. Of course, the arrangement of the compressor behind the low pressure part is not limited to this arrangement. It is possible that the compressor is arranged, for example between the turbine sections or on the high pressure side.

Um den Wirkungsgrad weiter zu verbessern, ist es vorteilhaft im Sinne der Erfindung, wenn der zumindest einen Gasturbine und/oder der Dampfturbine jeweils mehrere Verdichter zugeordnet sind, die mit dem zumindest einen Verdichter in Reihe geschaltet oder parallel dazu geschaltet sind.To further improve the efficiency, it is advantageous for the purposes of the invention if the at least one gas turbine and / or the steam turbine are each assigned a plurality of compressors, which are connected in series with the at least one compressor or connected in parallel thereto.

Denkbar ist, dass dem zumindest einen Verdichter ein Generator oder eine elektrische Arbeitsmaschine bzw. ein Elektromotor nachgeschaltet ist, um z.B. andere Maschinen anzutreiben.It is conceivable that the at least one compressor, a generator or an electric machine or an electric motor is connected downstream, for example, to drive other machines.

Günstig im Sinne der Erfindung ist, wenn der zumindest eine der Gasturbine zugeordnete Verdichter und die Gasturbine eine gemeinsame Welle aufweisen, so dass der Wirkungsgrad weiter verbessert wird. Natürlich können auch zwei getrennte Wellenteile der jeweiligen Komponente vorgesehen sein, welche mit geeigneten Mitteln miteinander verbunden sind. Auch wenn einen Mehrzahl von Verdichtern in Reihe geschaltet sind, kann einen gemeinsame Welle vorgesehen sein. Natürlich können auch der zumindest eine der Dampfturbine zugeordnete Verdichter und die Dampfturbine eine gemeinsame Welle aufweisen, wobei selbstverständlich auch getrennte Wellenteile wie oben genannt möglich sind.Favorable in the context of the invention is when the at least one of the gas turbine associated compressor and the gas turbine have a common shaft, so that the efficiency is further improved. Of course, two separate shaft parts of the respective component may be provided, which are interconnected by suitable means. Although a plurality of compressors are connected in series, a common shaft may be provided. Of course, the at least one of the steam turbine associated compressor and the steam turbine may have a common shaft, which of course also separate shaft parts as mentioned above are possible.

Der jeweilige Verdichter, welcher direkt von der Gasturbine bzw. der Dampfturbine angetrieben ist kann beispielsweise als Verdichter einer Gasverflüssigungsanlage, z.B. einer LNG-Anlage eingesetzt werden.The respective compressor, which is driven directly by the gas turbine or the steam turbine, for example, as a compressor of a gas liquefaction plant, e.g. a LNG plant.

Der in der Dampferzeugungsanlage 4 erzeugte Dampf wird der Dampfturbine 3 zugeführt und treibt diese an.The exhaust gases of the gas turbine 2 fuel a steam generating plant 4, which is designed as a waste heat boiler. The steam generated in the steam generating plant 4 is supplied to the steam turbine 3 and drives it.

Den dargestellten Gasturbinen 2 ist ein Starter-Helpermotor-Generator (SHMG) 10 zugeordnet. Der Starter-Helpermotor-Generator (SHMG) 10 kann sowohl als Helpermotor (Hilfsmotor) als auch als Generator eingesetzt werden. Der Starter ist im Sinne der Erfindung derart zu verstehen, dass der Motor - ähnlich wie bei einem Automotor - den Anlasser darstellt, und dafür Sorge trägt, die Gasturbine auf eine Drehzahl zu bringen, dass die Gasturbine dazu in der Lage ist, den Wellenstrang allein zu betreiben.The illustrated gas turbine 2 is a starter helper motor generator (SHMG) 10 assigned. The starter helper motor generator (SHMG) 10 can be used both as a helper motor (auxiliary motor) and as a generator. The starter is in Understand the meaning of the invention such that the engine - as in a car engine - is the starter, and ensures to bring the gas turbine to a speed that the gas turbine is able to operate the shaft train alone.

In der in Figur 1 dargestellten beispielhaften Verdichtungsanlage 1 ist der Gasprozess (Gasturbine 2) und der Dampfprozess (Dampfturbine 3) zu einem Gas- und Dampfprozess (GuD-Prozess) kombiniert.In the exemplary compression plant 1 shown in FIG. 1, the gas process (gas turbine 2) and the steam process (steam turbine 3) are combined to form a gas and steam process (gas and steam process).

Die Dampfturbine 3 gemäß dem dargestellten Ausführungsbeispiel weist einen Hochdruckteil 6, einen Mitteldruckteil 7 und einen Niederdruckteil 8 auf.The steam turbine 3 according to the illustrated embodiment has a high-pressure part 6, a medium-pressure part 7 and a low-pressure part 8.

Sowohl der zumindest einen Gasturbine 2 als auch der Dampfturbine 3 ist jeweils zumindest ein Verdichter 9 zugeordnet. Die jeweiligen Verdichter 9 sind jeweils direkt mit der zumindest einen Gasturbine 2 und der Dampfturbine 3 verbunden, wobei der zumindest eine der Dampfturbine 3 zugeordnete Verdichter 9 hinter dem Niederdruckteil 8 der Dampfturbine 3 angeordnet ist. Die jeweils der zumindest einen Gasturbine 2 und der Dampfturbine 3 zugeordneten Verdichter 9 werden so jeweils direkt von der Gasturbine 2 und der Dampfturbine 3, ohne Zwischenschaltung einer elektrischen Arbeitsmaschine bzw. eines Elektromotors angetrieben, wobei den Gasturbinen allerdings der Starter-Helpermotor-Generator (SHMG) 10 zuzuordnen ist.Both the at least one gas turbine 2 and the steam turbine 3 are each assigned at least one compressor 9. The respective compressors 9 are each directly connected to the at least one gas turbine 2 and the steam turbine 3, wherein the at least one of the steam turbine 3 associated compressor 9 is disposed behind the low pressure part 8 of the steam turbine 3. Each of the at least one gas turbine 2 and the steam turbine 3 associated compressor 9 are each driven directly from the gas turbine 2 and the steam turbine 3, without the interposition of an electric machine or an electric motor, the gas turbines, however, the starter helper motor generator (SHMG ) 10 is assigned.

Nicht dargestellt ist in dem Ausführungsbeispiel zu Figur 1, dass einem oder mehreren Verdichtern 9 eine elektrische Arbeitsmaschine bzw. ein Elektromotor und/oder ein Generator nachgeschaltet sein kann. Selbstverständlich soll die Positionierung des Verdichters 9 in den Wellensträngen nicht auf die offenbarte Position beschränkt sein, sondern kann variabel gestaltet werden.Not shown in the embodiment of Figure 1 that one or more compressors 9, an electric machine or an electric motor and / or a generator may be connected downstream. Of course, the positioning of the compressor 9 in the shaft strands should not be limited to the disclosed position, but may be made variable.

Möglich ist, dass der der Gasturbine 2 zumindest eine Verdichter 9 und die zumindest eine Gasturbine 2 eine gemeinsame Welle (Linie 11) aufweisen. Weiter können der zumindest eine der Dampfturbine 3, bzw. dessen Niederdruckteil 8 zugeordnete Verdichter 9 und die Dampfturbine 3 bzw. Niederdruckteil 8 eine gemeinsame Welle 12 aufweisen.It is possible for the gas turbine 2 to have at least one compressor 9 and the at least one gas turbine 2 to have a common shaft (line 11). Further, the at least one of the steam turbine 3, or its low-pressure part 8 associated compressor 9 and the steam turbine 3 and low pressure part 8 may have a common shaft 12.

Der jeweilige Verdichter 9 kann beispielsweise eine Betriebsmedium bzw. ein Betriebsgas verdichten, so dass das Betriebsmedium bei einer späteren Expansion Wärme aufnehmen kann. Denkbar ist beispielsweise, dass das in dem jeweiligen Verdichter 9 verdichtete Betriebsmedium einer Gasverflüssigungsanlage, zum Beispiel einer LNG-Anlage (Liquified Natural Gas) zugeführt wird um Erdgas abzukühlen.The respective compressor 9 can, for example, compress an operating medium or an operating gas so that the operating medium can absorb heat during a later expansion. It is conceivable, for example, that the compressed in the respective compressor 9 operating medium of a gas liquefaction plant, for example, a LNG plant (Liquefied Natural Gas) is supplied to cool natural gas.
