Description

Die Erfindung betrifft eine winterfeste Turboverdichtereinheit und ein Verfahren zur Winterfestmachung der Turboverdichtereinheit.The invention relates to a winter-proof turbocompressor unit and to a method for winterizing the turbocompressor unit.

Ein Turboverdichter findet in einer Chemieanlage der chemischen Industrie Anwendung. Die Chemieanlage ist an einem speziellen Standort angesiedelt, der beispielsweise durch das Vorkommen von einem Bodenschatz bestimmt sein kann. Der Bodenschatz ist beispielsweise Erdgas, das in einer Klimazone gefördert wird, die durch niedrige Temperaturen gekennzeichnet ist, wie beispielsweise eine Tundra. In der Tundra herrschen während den Sommermonaten Temperaturen, die knapp über dem Gefrierpunkt liegen, und in den Wintermonaten Temperaturen, die weiter unter dem Gefrierpunkt liegen. Somit ist der Turboverdichter derart angepasst auszustatten, dass er bei den tiefen Temperaturen, insbesondere während den Wintermonaten, sicher und störungsfrei betreibbar ist.A turbo-compressor is used in a chemical plant of the chemical industry. The chemical plant is located in a special location, which can be determined, for example, by the occurrence of a mineral resource. The resource is, for example, natural gas that is produced in a climate zone characterized by low temperatures, such as a tundra. Temperatures in the tundra are just over freezing during the summer months, and temperatures are still below freezing during the winter months. Thus, the turbocompressor is equipped to be fitted so that it is safe and trouble-free operation at low temperatures, especially during the winter months.

In Fig. 2 ist eine herkömmliche Turboverdichtereinheit 101 gezeigt. Die Turboverdichtereinheit 101 weist einen Turboverdichter 102 auf, der einen Rotor 103 aufweist. Der Rotor 103 ist mit Lager 104 gelagert, beispielsweise mit Kippsegmentgleitlager. Herkömmlich sind die Kippsegmentgleitlager 104 ölgeschmiert. Zur Versorgung der Kippsegmentgleitlager 104 mit einem Schmieröl 113 weist der Turboverdichter 101 eine Ölversorgungsanlage 107 mit einer Ölzuführleitung 108 und einer Ölrückführleitung 109 auf. Die Ölzuführleitung 108 ist an die eine Ölzuführsammelleitung 105 des Turboverdichters 102 angeschlossen, via die das Schmieröl 113 zu den Kippsegmentgleitlagern 104 zugeführt wird. Zum Abführen des Schmieröls 113 von den Kippsegmentgleitlagern 104 weist der Turboverdichter 102 eine Ölrückführsammelleitung 106 auf, die an die Ölrückführleitung 109 angeschlossen ist. Ferner weist die Ölversorgungsanlage 107 einen Öltank 110 auf, der mit dem Schmieröl 113 gefüllt ist. Zum Befüllen des Öltanks 110 ist an dem Öltank 110 ein Einfüllstutzen 111 vorgesehen. In den Öltank 110 ist eine Ölpumpe 112 eingebaut, mit der das Schmieröl 113 zu den Kippsegmentgleitlagern 104 via die Ölzuführleitung 108 und die Ölzuführsammelleitung 105 gefördert wird.In Fig. 2 a conventional turbocompressor unit 101 is shown. The turbocompressor unit 101 has a turbocompressor 102 which has a rotor 103. The rotor 103 is mounted with bearings 104, for example with Kippsegmentgleitlager. Conventionally, the Kippsegmentgleitlager 104 are oil lubricated. To supply the tilting pad sliding bearing 104 with a lubricating oil 113, the turbocompressor 101 has an oil supply system 107 with an oil feed line 108 and an oil return line 109. The oil supply line 108 is connected to the one oil supply manifold 105 of the turbocompressor 102, via which the lubricating oil 113 is supplied to the tilting pad plain bearings 104. For discharging the lubricating oil 113 from the Kippsegmentgleitlagern 104, the turbocompressor 102 has an oil return manifold 106 which is connected to the oil return line 109 is connected. Furthermore, the oil supply system 107 has an oil tank 110 which is filled with the lubricating oil 113. For filling the oil tank 110, a filler neck 111 is provided on the oil tank 110. In the oil tank 110, an oil pump 112 is installed, with which the lubricating oil 113 is conveyed to the Kippsegmentgleitlagern 104 via the oil supply line 108 and the oil supply manifold 105.

Herkömmlich ist die Turboverdichtereinheit 101 im Freien untergebracht, so dass die Turboverdichtereinheit 101 den Außentemperaturen ihres Standorts ausgesetzt ist. Ist die Turboverdichtereinheit 101 in einer Tundra angesiedelt, sind die Außentemperaturen zumindest zeitweise derart niedrig, dass das Schmieröl 113 für den Betrieb des Turboverdichters 102, d.h. der Schmierung der Kippsegmentgleitlager 104, nicht brauchbar ist. Deshalb ist die Turboverdichtereinheit 101 mit Einrichtungen versehen, die es ermöglichen, dass die Turboverdichtereinheit 101 auch bei den niedrigen Außentemperaturen betrieben werden kann. Diese Einrichtungen sind eine Wärmeisolierung 114 (in Fig. 2 schematisch dargestellt), mit der die Ölzuführleitung 108 wärmeisoliert ist. Ferner weist der Öltank 110 eine Ölheizung 115 auf, mit der das Schmieröl 113 in dem Tank 110 auf eine notwendige Betriebstemperatur aufgeheizt wird. Die Ölheizung 115 wird herkömmlich mit elektrischem Strom betrieben.Conventionally, the turbocompressor unit 101 is housed outdoors, so that the turbocompressor unit 101 is exposed to the outside temperatures of its location. If the turbocompressor unit 101 is located in a tundra, the outside temperatures are at least temporarily so low that the lubricating oil 113 is not usable for the operation of the turbocompressor 102, ie the lubrication of the tilting pad plain bearings 104. Therefore, the turbocompressor unit 101 is provided with means for allowing the turbocompressor unit 101 to operate even at the low outside temperatures. These facilities are a thermal insulation 114 (in Fig. 2 shown schematically), with which the oil supply line 108 is thermally insulated. Furthermore, the oil tank 110 has an oil heater 115, with which the lubricating oil 113 is heated in the tank 110 to a necessary operating temperature. The oil heater 115 is conventionally powered by electric power.

Das Vorsehen der Wärmeisolierung 114 und der Ölheizung 115 ist aufwändig in der Herstellung der Turboverdichtereinheit 101 und kostenintensiv. Fällt bei niedrigen Außentemperaturen die Ölheizung 115 aus, so kann das Schmieröl 113 in dem Öltank 110 nicht mehr auf die notwendige Betriebstemperatur gebracht werden, so dass die Turboverdichtereinheit 101 abgeschaltet werden muss. Abhilfe könnten hier entsprechende sicherheitsrelevante Einrichtungen schaffen, um die Ölheizung 115 ausfallsicher zu gestalten. Diese Einrichtungen erfordern einen erhöhten Engineering-Aufwand bei der Planung und beim Bau der Chemieanlage, sowie erhöhte Investitionsaufwendungen.The provision of the heat insulation 114 and the oil heater 115 is expensive in the production of the turbo compressor unit 101 and costly. If the oil heater 115 fails at low outside temperatures, the lubricating oil 113 in the oil tank 110 can no longer be brought to the required operating temperature, so that the turbocompressor unit 101 has to be switched off. Remedy could provide appropriate safety-relevant facilities to make the oil heater 115 fail-safe here. These facilities require increased engineering effort in the design and construction of the chemical plant, as well as increased capital expenditures.

Aufgabe der Erfindung ist es, eine winterfeste Turboverdichtereinheit und ein Verfahren zur Winterfestmachung der Turboverdichtereinheit zu schaffen, die bei niedrigen Außentemperaturen sicher betreibbar ist, wobei der Engineering-Aufwand und die Investitionskosten gering sind.The object of the invention is to provide a winter-proof turbocompressor unit and a method for winterizing the turbocompressor unit, which is safe to operate at low outside temperatures, the engineering effort and investment costs are low.

Die erfindungsgemäße winterfeste Turboverdichtereinheit weist einen Turboverdichter und eine Ölversorgungsanlage zum Versorgen des Turboverdichters mit einem Schmieröl auf, wobei das Schmieröl ein Tieftemperaturöl ist und der Turboverdichter und die Ölversorgungsanlage für den Betrieb mit dem Tieftemperaturöl eingerichtet sind.The winterized turbocompressor unit according to the invention has a turbocompressor and an oil supply system for supplying the turbo-compressor with a lubricating oil, wherein the lubricating oil is a cryogenic oil and the turbocompressor and the oilsupply system are set up for operation with the cryogenic oil.

Erfindungsgemäß wird das Tieftemperaturöl in der Turboverdichtereinheit mit dem Turboverdichter und der Ölversorgungsanlage zum Versorgen des Turboverdichters mit dem Tieftemperaturöl als das Schmieröl verwendet, wobei der Turboverdichter und die Ölversorgungsanlage für den Betrieb mit dem Tieftemperaturöl eingerichtet sind.According to the invention, the cryogenic oil in the turbocompressor unit with the turbocompressor and the oilsupply system for supplying the turbo-compressor with the cryogenic oil is used as the lubricating oil, the turbocompressor and the oilsupply system being arranged for operation with the cryogenic oil.

Das erfindungsgemäße Verfahren zur Winterfestmachung der Turboverdichtereinheit mit dem Turboverdichter und der Ölversorgungsanlage zum Versorgen des Turboverdichters mit dem Schmieröl weist den Schritt auf: Einfüllen des Tieftemperaturöls in die Ölversorgungsanlage als das Schmieröl.The method according to the invention for winterizing the turbocompressor unit with the turbocompressor and the oil supply system for supplying the turbocompressor with the lubricating oil comprises the step of: charging the cryogenic oil into the oil supply system as the lubricating oil.

Das Schmieröl ist vom Typ des Tieftemperaturöls, dessen minimal mögliche Betriebstemperatur niedriger ist als die eines herkömmlichen Schmieröls. Daher kann das Tieftemperaturöl bei niedrigeren Temperaturen zum Betreiben der Turboverdichtereinheit verwendet werden, als es mit dem herkömmlichen Schmieröl möglich wäre. Derart niedrige Temperaturen sind beispielsweise die Außentemperaturen in einer kalten Klimazone, beispielsweise einer Tundra während den Wintermonaten. Die Turboverdichtereinheit braucht nicht mit Maßnahmen zur Erwärmung und/oder Warmhaltung des Schmieröls ausgestattet zu sein, wie beispielsweise eine Ölheizung, die das Schmieröl auf Temperatur halten könnte, und/oder eine Wärmeisolierung von Ölleitungen. Daraus ergeben sich ein geringer Aufwand beim Engineering der Turboverdichtereinheit und geringe Investitionskosten. Ferner braucht beim Betrieb der Turboverdichtereinheit auf eine zu niedrige Temperierung des Schmieröls keine Rücksicht genommen zu werden, so dass der Betrieb der Turboverdichtereinheit einfach ist.The lubricating oil is of the type of cryogenic oil whose minimum possible operating temperature is lower than that of a conventional lubricating oil. Therefore, the lower temperature oil can be used at lower temperatures to operate the turbocompressor unit than would be possible with the conventional lubricating oil. Such low temperatures are, for example, the outside temperatures in a cold climatic zone, such as a tundra during the winter months. The turbo compressor unit does not need measures for heating and / or keeping warm the Lubricating oil to be equipped, such as an oil heater, which could keep the lubricating oil to temperature, and / or thermal insulation of oil lines. This results in a low effort in engineering the turbo compressor unit and low investment costs. Furthermore, when operating the turbocompressor unit, it is unnecessary to take into consideration a too low temperature control of the lubricating oil, so that the operation of the turbocompressor unit is simple.

Bevorzugt ist das Tieftemperaturöl ein Öl nach ISO VG 46 und hat einen tiefen Stockpunkt bei -54°C und eine Tauglichkeit als Schmieröl bei bis zu 20°C.Preferably, the low temperature oil is an oil according to ISO VG 46 and has a low pour point at -54 ° C and a suitability as a lubricating oil at up to 20 ° C.

Die Turboverdichtereinheit, die mit dem Tieftemperaturöl betrieben ist, kann somit vorteilhaft bis zu einer Außentemperatur von bis zu -20°C sicher betrieben werden, ohne dass zusätzliche Maßnahmen, wie beispielsweise eine Wärmeisolierung von Ölleitungen und/oder eine Ölheizung vorgesehen zu werden brauchen.The turbocompressor unit, which is operated with the cryogenic oil, can thus be advantageously operated safely up to an outside temperature of up to -20 ° C, without additional measures, such as a heat insulation of oil lines and / or oil heating need to be provided.

Ferner ist das Tieftemperaturöl ein Öl nach ISO VG 46 und hat einen tiefen Stockpunkt unter -54°C und eine Tauglichkeit als Schmieröl bei bis zu -30°C.Furthermore, the low temperature oil is an oil according to ISO VG 46 and has a low pour point below -54 ° C and a suitability as a lubricating oil at -30 ° C.

Somit kann die Turboverdichtereinheit mit dem Schmieröl bei einer Außentemperatur bis zu -30°C betrieben werden, ohne dass zusätzliche Maßnahmen, wie beispielsweise eine Wärmeisolierung von Ölleitungen und/oder eine Ölheizung vorgesehen zu werden brauchen.Thus, the turbo compressor unit can be operated with the lubricating oil at an outdoor temperature up to -30 ° C, without additional measures, such as heat insulation of oil lines and / or oil heating need to be provided.

Im Folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels der Turboverdichtereinheit unter Bezugnahme auf die schematischen Zeichnungen beschrieben. Es zeigt

In the following, the invention will be described with reference to a preferred embodiment of the turbocompressor unit with reference to the schematic drawings. It shows
Fig. 1
an embodiment of the turbocompressor unit according to the invention and
Fig. 2
a conventional turbocompressor unit.

Wie es aus Fig. 1 ersichtlich ist, weist eine Turboverdichtereinheit 1 einen Turboverdichter 2 auf, der einen Rotor 3 zum Verdichten von Gas aufweist. Der Rotor 3 ist mittels Lager 4 gelagert. Die Lager 4 sind Kippsegmentgleitlager, die zu deren Schmierung mit Schmieröl 13 versorgt sind. Die Schmierölversorgung wird bewerkstelligt durch eine Zuführung des Schmieröls 13 durch eine Ölzuführsammelleitung 5 und eine Abführung des Schmieröls durch eine Ölrückführsammelleitung 6.Like it out Fig. 1 As can be seen, a turbocompressor unit 1 has a turbocompressor 2, which has a rotor 3 for compressing gas. The rotor 3 is supported by bearings 4. The bearings 4 are Kippsegmentgleitlager, which are supplied to the lubrication with lubricating oil 13. The lubricating oil supply is accomplished by supplying the lubricating oil 13 through an oil supply manifold 5 and discharging the lubricating oil through an oil return manifold 6.

Die Turboverdichtereinheit 1 weist ferner zur Versorgung der Lager 4 mit dem Schmieröl 13 eine Ölversorgungsanlage 7 mit einer Ölzuführleitung 8 und einer Ölrückführleitung 9 auf. Die Ölzuführleitung 8 ist mit der Ölzuführsammelleitung 5 schmierölleitend verbunden, und die Ölrückführleitung 9 ist mit der Ölrückführsammelleitung 6 schmierölleitend verbunden. Die Ölversorgungsanlage 7 weist einen Öltank 10 auf, an den sowohl die Ölzuführleitung 8 als auch die Ölrückführleitung 9 angeschlossen sind. Der Öltank 10 weist eine Füllung mit dem Schmieröl 13 und einen Einfüllstutzen 11 auf, durch den das Schmieröl 13 in den Öltank 10 eingefüllt worden ist. Ferner weist der Öltank 10 eine Ölpumpe 12 auf, die zum Fördern des Schmieröls 13 in die Ölzuführleitung 8 in den Öltank 10 eingebaut ist.The turbocompressor unit 1 also has an oil supply system 7 with an oil supply line 8 and an oil return line 9 for supplying the bearings 4 with the lubricating oil 13. The oil supply pipe 8 is connected to the oil supply manifold 5 lubricating oil, and the oil return line 9 is connected to the oil return manifold 6 lubricating oil. The oil supply system 7 has an oil tank 10, to which both the oil supply 8 and the oil return line 9 are connected. The oil tank 10 has a filling with the lubricating oil 13 and a filler neck 11, through which the lubricating oil 13 has been filled in the oil tank 10. Further, the oil tank 10 has an oil pump 12 installed to supply the lubricating oil 13 to the oil supply pipe 8 in the oil tank 10.

Unter Betreiben der Ölpumpe 12 wird das Schmieröl 13 aus dem Öltank 10 angesaugt und in die Ölzuführleitung 8 gefördert. Von der Ölzuführleitung 8 wird das Schmieröl 13 in die Ölzuführsammelleitung 6 gefördert und an die Lager 4 zu deren Schmierung gebracht. Von den Lagern 4 läuft das Schmieröl 13 in die Ölrückführsammelleitung 6 und in die Ölrückführleitung 9, um dann in den Öltank 10 zurückzugelangen. Dadurch wird von der Ölpumpe 13, der Ölzuführleitung 8, der Ölzuführsammelleitung 5, der Ölrückführsammelleitung 6, der Ölrückführleitung 9 und dem Öltank 10 ein Ölkreislauf gebildet.Under operation of the oil pump 12, the lubricating oil 13 is sucked from the oil tank 10 and conveyed into the oil supply 8. From the oil supply line 8, the lubricating oil 13 is fed into the oil supply manifold 6 and brought to the bearings 4 to the lubrication. From the bearings 4, the lubricating oil 13 runs in the oil return manifold 6 and in the oil return line 9 to then return to the oil tank 10. Thereby, by the oil pump 13, the oil supply 8, the oil supply manifold 5, the oil return manifold 6, the Oil return line 9 and the oil tank 10 formed an oil circuit.

Das Schmieröl 13 ist ein Tieftemperaturöl, beispielsweise das Öl "Shell Corena AS, ISO VG 46".The lubricating oil 13 is a cryogenic oil, for example the oil "Shell Corena AS, ISO VG 46".

In der Turboverdichtereinheit 1 sind insbesondere weder die Ölzuführleitung 8 noch die Ölrückführleitung 9 wärmeisoliert vorgesehen. Ferner ist in dem Öltank 10 eine Ölheizung nicht vorgesehen.In the turbocompressor unit 1, in particular, neither the oil feed pipe 8 nor the oil return pipe 9 are provided in a heat-insulated manner. Further, oil heating is not provided in the oil tank 10.

Beim Umwälzen des Schmieröl 13 in dem Ölkreislauf hat es in dem Öltank 10 aufgrund dessen Volumen eine gewisse Verweilzeit. In der Regel ist die Verweilzeit derart lang, dass das Schmieröl 13 in dem Öltank 10 die Umgebungstemperatur des Öltanks 10 annimmt. Passiert das Schmieröl 13 die Lager 4, so wird aufgrund von Reibungseffekten in den Lagern 4 das Schmieröl 13 in den Lagern 4 erwärmt. Das dadurch erwärmte Schmieröl 13 wird dann via der Ölrückführsammelleitung 6 und der Ölrückführleitung 9 zurück in den Öltank 10 geführt. Dort kühlt sich das erwärmte Schmieröl 13 wieder auf die Umgebungstemperatur des Öltanks 10 ab.When circulating the lubricating oil 13 in the oil circuit, it has a certain residence time in the oil tank 10 due to its volume. In general, the residence time is so long that the lubricating oil 13 in the oil tank 10 assumes the ambient temperature of the oil tank 10. If the lubricating oil 13 passes the bearings 4, the lubricating oil 13 in the bearings 4 is heated due to friction effects in the bearings 4. The thus heated lubricating oil 13 is then fed via the oil return manifold 6 and the oil return line 9 back into the oil tank 10. There, the heated lubricating oil 13 cools down again to the ambient temperature of the oil tank 10.

Dadurch, dass das Schmieröl 13 einen tiefen Stockpunkt bei -54°C hat, ist der Turboverdichter 2 bis zu einer Umgebungstemperatur der Turboverdichtereinheit 1 bei bis zu - 20°C Umgebungstemperatur sicher und schadenfrei betreibbar. Somit ist die Turboverdichtereinheit 1 in einer Klimazone sicher betreibbar, in der die Umgebungstemperatur nicht unter -20°C abfällt.Because the lubricating oil 13 has a low pour point at -54 ° C., the turbocompressor 2 can be operated safely and without damage up to an ambient temperature of the turbocompressor unit 1 at up to -20 ° C. ambient temperature. Thus, the turbocompressor unit 1 is safe to operate in a climatic zone in which the ambient temperature does not drop below -20 ° C.
