Description

Die Erfindung betrifft ein Verfahren zum Innenreinigen eines einen Anschluss für das Zuführen von Fluid und einen Anschluss für das Abführen von Fluid aufweisenden Fluidtank, bei dem durch den Anschluss für das Zuführen von Fluid in den Fluidtank ein Primärfluid eingeleitet wird, und bei dem durch den Anschluss für das Abführen von Fluid aus dem Fluidtank ein Sekundärfluid in Form von in dem Fluidtank aufgenommenen Fluidresten und/oder mit solchen Fluidresten oder Schmutzstoffen beaufschlagtem Primärfluid abgeführt wird.The invention relates to a method for internally cleaning a fluid tank having a connection for supplying fluid and a connection for discharging fluid, in which a primary fluid is introduced through the connection for the supply of fluid into the fluid tank, and through which connection for discharging fluid from the fluid tank, a secondary fluid in the form of fluid residues accommodated in the fluid tank and / or primary fluid charged with such fluid residues or contaminants is removed.

Darüber hinaus betrifft die Erfindung eine Anlage zum Innenreinigen eines einen Anschluss für das Zuführen von Fluid und einen Anschluss für das Abführen von Fluid aufweisenden Fluidtank, die eine an den Anschluss für das Zuführen von Fluid anschließbare Leitung für das Zuführen eines Primärfluids in den Fluidtank aufweist und eine an den Anschluss für das Abführen von Fluid anschließbaren Leitung für das Abführen eines Sekundärfluids in Form von in dem Fluidtank aufgenommenen Fluidresten und/oder mit solchen Fluidresten oder Schmutzstoffen beaufschlagtem Primärfluid hat.Moreover, the invention relates to a system for internally cleaning a fluid delivery port and a fluid discharge port, which has a conduit connectable to the fluid supply port for supplying a primary fluid into the fluid tank, and a conduit connectable to the fluid discharge port for discharging a secondary fluid in the form of fluid residues received in the fluid tank and / or primary fluid impinged upon such fluid residues or contaminants.

Unter einem Fluidtank wird im Sinne der Erfindung ein geschlossener Behälter für die Lagerung, Bevorratung und/oder den Transport von gasförmigen und/oder flüssigen Medien verstanden, wie z.B. Propan, Butan, Butadien, Propen, Isobutan, Isobuten, Cyclobutan, Otto- oder Dieselkraftstoff, Biodiesel, Heizöl, Cyclobutan, Gemische dieser Medien, oder andere flüchtige, organische Verbindungen enthaltende oder aus diesen bestehende Fluide oder andere, brennbare Bestandteile enthaltende Fluide.For the purposes of the invention, a fluid tank means a closed container for the storage, storage and / or transport of gaseous and / or liquid media, such as e.g. Propane, butane, butadiene, propene, isobutane, isobutene, cyclobutane, gasoline or diesel fuel, biodiesel, fuel oil, cyclobutane, mixtures of these media, or other volatile, organic compounds containing or consisting of these fluids or other combustibles containing fluids.

Vor dem Durchführen von Wartungsarbeiten und Sicherheitsüberprüfungen an einem Fluidtank, sowie um das Aufnehmen von insbesondere wechselnden unterschiedlichen Fluiden vorzubereiten, ist bei Fluidtanks regelmäßig eine Innenreinigung erforderlich.Prior to performing maintenance and safety checks on a fluid tank, as well as to prepare for accommodating particular varying different fluids, fluid cleaning requires regular internal cleaning.

Für das Innenreinigen von Fluidtanks ist es bekannt, den Innenraum mit einem Primärfluid in Form von Inertgas, z.B. mit gasförmigem Stickstoff zu spülen, um darin aufgenommene Fluidreste und Schmutzstoffe auszutreiben. Aufgrund der für das Spülen von Fluidtanks erforderlichen großen Gasmengen ist eine solche Innenreinigung von Fluidtanks sehr kostenintensiv. Herkömmlich werden die aus einem Fluidtank entfernten Fluidreste und Schmutzstoffe keiner planmäßigen Verwertung zugeführt, sondern lediglich durch Abfackeln vernichtet.For internally cleaning fluid tanks, it is known to seal the interior with a primary fluid in the form of inert gas, e.g. to purge with gaseous nitrogen to expel contained therein fluid residue and contaminants. Due to the large quantities of gas required for flushing fluid tanks, such internal cleaning of fluid tanks is very cost-intensive. Conventionally, the fluid residues removed from a fluid tank and contaminants are not supplied to scheduled recovery, but destroyed only by flaring.

Aufgabe der Erfindung ist es, ein Verfahren für das Innenreinigen von Fluidtanks bereitzustellen, das ein kostengünstiges Innenreinigen von Fluidtanks ermöglicht, und eine Anlage für das Innenreinigen von Fluidtanks zu schaffen, die sich mit geringen Betriebskosten betreiben lässt.The object of the invention is to provide a method for the internal cleaning of fluid tanks, which allows a cost-effective internal cleaning of fluid tanks, and to provide a system for the internal cleaning of fluid tanks, which can be operated with low operating costs.

Diese Aufgabe wird zum einen durch ein Verfahren für das Innereinigen von Fluidtanks der eingangs genannten Art gelöst, bei dem das dem Fluidtank zugeführte Primärfluid auf eine für das Innenreinigen des Fluidtanks günstige Prozesstemperatur erwärmt wird. Zum anderen wird diese Aufgabe durch eine Anlage der eingangs genannten Art gelöst, die eine Konditioniereinrichtung für das Erwärmen des dem Fluidtank zugeführten Primärfluids auf eine für das Innenreinigen des Fluidtanks günstige Prozesstemperatur enthält.This object is achieved, on the one hand, by a method for cleaning internal fluid tanks of the type mentioned in the introduction, in which the primary fluid supplied to the fluid tank is heated to a process temperature which is favorable for the internal cleaning of the fluid tank. On the other hand, this object is achieved by a plant of the type mentioned, which contains a conditioning device for heating the primary fluid supplied to the fluid tank to a favorable for the internal cleaning of the fluid tank process temperature.

Wegen der Explosionsgefahr können Fluidtanks, die mit brennbaren Gasen oder Flüssigkeiten befüllt wurden, nicht mit Druckluft gespült werden. Für das Reinigen von solchen Fluidtanks mittels Spülen ist deshalb aus Sicherheitsgründen der Einsatz von chemisch inertem Primärfluid erforderlich, wie z.B. Stickstoff. Die Erfinder haben erkannt, dass die Reinigungswirkung von für das Reinigen von Fluidtanks eingesetztem Primärfluid erheblich gesteigert werden kann, indem das Primärfluid vor dem Zuführen in einen Fluidtank konditioniert, d.h. auf eine für das Reinigen und Spülen günstige Temperatur aufgewärmt wird. Indem das Primärfluid erwärmt wird, ist es insbesondere möglich, in den Fluidtanks aufgenommene Flüssigkeiten durch das Übertragen von Wärme aus dem Primärfluid zu verdampfen und aus den Fluidtanks auszutreiben.Due to the risk of explosion, fluid tanks filled with flammable gases or liquids can not be flushed with compressed air. For cleaning such fluid tanks by means of rinsing, the use of chemically inert primary fluid, such as nitrogen, is therefore necessary for safety reasons. The inventors have recognized that the cleaning effect of primary fluid used for cleaning fluid tanks can be significantly increased by conditioning the primary fluid prior to feeding it into a fluid tank, ie warming it to a temperature favorable for cleaning and rinsing. In particular, by heating the primary fluid it is possible to evaporate liquids taken up in the fluid tanks by transferring heat from the primary fluid and drive them out of the fluid tanks.

Bei einem Einsatz von gasförmigem Primärfluid für das Spülen, wie z.B. Stickstoff, werden für die Reinigung von Eisenbahn-Kesselwägen, von Tanklastwagen oder auch von Schiffstanks mit einem Tankvolumen, das häufig in der Größenordnung von 20m3 liegt, sehr große Gasmengen von 700m3 oder mehr benötigt, was zu erheblichen Kosten führt.When using gaseous primary fluid for purging, such as nitrogen, for the cleaning of railroad tank cars, tankers or even ship tanks with a tank volume, which is often in the order of 20m 3 , very large gas quantities of 700m 3 or more needed, which leads to considerable costs.

Eine Idee der Erfindung besteht deshalb auch darin, das für das Innenreinigen von Fluidtanks eingesetzte Primärfluid zu erwärmen, bevor es in den Fluidtank eingeleitet wird, um die für das Spülen eines Fluidtanks erforderliche Menge von Primärfluid zu verringern. Darüber hinaus ist es eine Idee der Erfindung, die für das Erwärmen des Primärfluids benötigte Energie aus in den Fluidtanks aufgenommenem Sekundärfluid und Schmutzstoffen zu gewinnen, die aus den Fluidtanks entfernt werden.Therefore, an idea of the invention is also to heat the primary fluid used for internally cleaning fluid tanks before it is introduced into the fluid tank in order to reduce the amount of primary fluid required for flushing a fluid tank. Moreover, it is an idea of the invention to recover the energy needed to heat the primary fluid from secondary fluid received in the fluid tanks and contaminants removed from the fluid tanks.

Erfindungsgemäß wird deshalb vorgeschlagen, das aus einem Fluidtank bei dem Spülen abgeführte Sekundärfluid wenigstens teilweise einer Einrichtung für das chemische Umsetzen des Sekundärfluids unter Freisetzen von Wärme zuzuführen, um die darin freigesetzte Wärme dann wenigstens teilweise auf das dem Fluidtank zugeführte Primärfluid zu übertragen. Mit dieser Maßnahme ist es insbesondere möglich, die für das Reinigen von Fluidtanks benötigte Zeitspanne zu verringern und auf diese Weise auch die Wartungsintervalle für z.B. Eisenbahn-Kesselwagen, Tanklastwagen oder Schifftanks zu verkürzen. Die Einrichtung für das chemische Umsetzen des Sekundärfluids kann z.B. ein Brenner sein, in dem das Sekundärfluid mit einem weiteren brennbaren Fluid verbrannt wird.According to the invention, therefore, it is proposed to at least partially supply the secondary fluid discharged from a fluid tank during purging to a means for chemically reacting the secondary fluid to release heat to transfer the heat released therein at least partially to the primary fluid supplied to the fluid tank. With this measure it is possible in particular to reduce the time required for the cleaning of fluid tanks and in this way also to reduce the maintenance intervals for e.g. To shorten railway tank cars, tank trucks or ship tanks. The means for the chemical reaction of the secondary fluid may e.g. a burner in which the secondary fluid is burned with another combustible fluid.

Von Vorteil ist es, wenn der Brenner in ein vorzugsweise als Mikrogasturbine ausgebildetes Turbinensystem integriert ist und einen Heißgasstrom erzeugt, mit dem für das Erzeugen von kinetischer Energie eine Gasturbine beaufschlagt wird, die mit einem mechanischen Energieverbraucher bewegungsgekoppelt ist. Die in dem Abgasstrom der Gasturbine enthaltene thermische Energie kann dann z.B. in der Konditioniereinrichtung zumindest teilweise auf das dem Fluidtank zugeführte Primärfluid übertragen werden.It is advantageous if the burner is integrated in a preferably designed as a micro gas turbine turbine system and generates a hot gas stream, which is acted upon for generating kinetic energy, a gas turbine, which is coupled in motion with a mechanical energy consumer. The thermal energy contained in the exhaust gas flow of the gas turbine can then be transferred, for example, in the conditioning device at least partially to the primary fluid supplied to the fluid tank.

Eine Idee der Erfindung ist es deshalb auch, ein Turbinensystem, insbesondere eine Mikrogasturbine zur Reinigung oder Spülung eines Fluidtanks mit einem Primärfluid einzusetzen, wobei das Turbinensystem einen Brenner und eine mit einem Verdichter gekoppelte Gasturbine umfasst. Dabei wird der Brenner mit einem Sekundärfluid versorgt, welches aus mit in dem Fluidtank aufgenommenen Fluidresten und/oder mit solchen Fluidresten oder Schmutzstoffen beaufschlagtem Primärfluid besteht, und es wird das von dem Turbinensystem freigesetzte Abgas einer Konditioniereinrichtung für das Konditionieren des Primärfluids zugeführt.An idea of the invention is therefore also to use a turbine system, in particular a micro gas turbine for cleaning or flushing a fluid tank with a primary fluid, wherein the turbine system comprises a burner and a compressor coupled to a gas turbine. In this case, the burner is supplied with a secondary fluid which consists of fluid residues accommodated in the fluid tank and / or primary fluid charged with such fluid residues or contaminants, and the exhaust gas released by the turbine system is supplied to a conditioning device for conditioning the primary fluid.

Um die Leistung der Gasturbine zu steigern und um die Temperatur des mit der Gasturbine erzeugten Abgasstroms zu erhöhen, ist es von Vorteil, wenn der mechanische Energieverbraucher ein Verdichter für das Verdichten von dem Brenner zugeführter Verbrennungsluft ist, wobei auf die mittels des Verdichters verdichtete Verbrennungsluft thermische Energie aus dem Abgasstrom übertragen wird. Der mechanische Energieverbraucher kann alternativ oder zusätzlich auch ein elektrischer Generator sein, der elektrischen Strom erzeugt.In order to increase the power of the gas turbine and to increase the temperature of the exhaust gas flow generated by the gas turbine, it is advantageous if the mechanical energy consumer is a compressor for compressing the combustion air supplied to the burner, wherein the combustion air compressed by the compressor thermal Energy is transferred from the exhaust stream. The mechanical energy consumer may alternatively or additionally also be an electrical generator which generates electrical current.

Darüber hinaus ist es möglich, einen entsprechenden Fluidtank mit der beim chemischen Umsetzen des Sekundärfluids freigesetzten Wärme von außen zu erwärmen, was insbesondere in der Winterzeit zu erheblichen Energieeinsparungen führen kann.Moreover, it is possible to heat a corresponding fluid tank with the heat released in the chemical reaction of the secondary fluid from the outside, which can lead to significant energy savings, especially in the winter time.

Von Vorteil ist es, in einer Anlage für das Innenreinigen von Fluidtanks einen Leitungsabschnitt vorzusehen, der die Leitung für das Abführen von Sekundärfluid aus einem Fluidtank mit der Leitung für das Zuführen von Primärfluid in den Fluidtank verbindet, um das aus dem Fluidtank abgeführte Sekundärfluid dem Fluidtank erneut zuzuführen. Auf diese Weise ist es möglich, einen Fluidtank mit Primärfluid zu beaufschlagen, das zumindest teilweise in einem Kreislauf geführt ist, so dass die für das Spülen eines Fluidtanks erforderliche Menge an Primärfluid mit dieser Maßnahme verringert werden kann.It is advantageous to provide in a system for the internal cleaning of fluid tanks, a line section, the conduit for the discharge of secondary fluid from a fluid tank communicates with the conduit for supplying primary fluid into the fluid tank to re-supply the secondary fluid discharged from the fluid tank to the fluid tank. In this way, it is possible to apply a fluid tank with primary fluid which is at least partially circulated, so that the amount of primary fluid required for flushing a fluid tank can be reduced by this measure.

Indem in diesem Leitungsabschnitt ein Wärmetauscher für das Übertragen von Abwärme aus dem Abgas der Gasturbine auf das dem Fluidkanal erneut zugeführte Primärfluid angeordnet ist, lässt sich dabei das für das Spülen eines Fluidtanks eingesetzte Primärfluid auf eine für das Reinigen günstige Prozesstemperatur konditionieren.By arranging in this line section a heat exchanger for the transfer of waste heat from the exhaust gas of the gas turbine to the primary fluid once again supplied to the fluid channel, the primary fluid used for rinsing a fluid tank can be conditioned to a process temperature which is favorable for the cleaning.

Im Folgenden wird die Erfindung anhand der in der Zeichnung in schematischer Weise dargestellten Ausführungsbeispiele näher erläutert.In the following the invention will be explained in more detail with reference to the embodiments schematically illustrated in the drawing.

Um das mit Fluidresten oder Schmutzstoffen beaufschlagte Stickstoffgas aus dem Fluidtank 12 durch die Leitung 30 in die Brennkammer 28 zu bewegen, enthält die Anlage 10 bevorzugt, aber nicht zwingend, eine als Verdichter oder Pumpe ausgebildete Saugfördereinheit 31. Der Brenner 28 hat eine Brennkammer 32, in der das mit Fluidresten oder Schmutzstoffen aus dem Fluidtank 12 beaufschlagte Stickstoffgas mit einem von außen zugeführten Brenngas und mit Verbrennungsluft verbrannt wird.The system 10 includes a micro gas turbine formed turbine system 26 with a burner 28. Via a line 30, which can be connected to the terminal 18 of the fluid tank 12, it is possible, the burner 28 in the turbine system 26 with fluid residues or polluted nitrogen gas as to supply a secondary fluid from the fluid tank 12. In order to move the nitrogen gas charged with fluid residues or contaminants from the fluid tank 12 through the conduit 30 into the combustion chamber 28, the plant 10 preferably, but not necessarily, includes a suction conveyor unit 31 designed as a compressor or pump. The burner 28 has a combustion chamber 32, in which the nitrogen gas charged with fluid residues or contaminants from the fluid tank 12 is burned with a fuel gas supplied from the outside and with combustion air.

Der Brenner 28 ist dazu bevorzugt als ein sogenannter Zweistufen-Brenner ausgebildet, der als eine erste Brennerstufe eine Pilotstufe hat, in die das Brenngas zugeführt wird, und der als eine zweite Brennerstufe eine Hauptstufe aufweist, in die das mit Fluidresten oder Schmutzstoffen beaufschlagte Stickstoffgas eingeleitet wird, um es dort in einer mittels der Pilotstufe erzeugten Brennerflamme zu verbrennen.The burner 28 is for this purpose preferably designed as a so-called two-stage burner, which has a pilot stage as a first burner stage, in which the fuel gas is supplied, and as a second burner stage has a main stage, in which introduced the pressurized with fluid residues or contaminants nitrogen gas is to burn it there in a burner flame generated by the pilot stage.

Es sei bemerkt, dass in einer modifizierten Ausführungsform der Brenner 28 für das Verbrennen von mit Fluidresten oder Schmutzstoffen aus dem Fluidtank 12 beaufschlagtem Stickstoffgas auch ein Brenner sein kann, der mit Fluidresten oder Schmutzstoffen beaufschlagtes Stickstoffgas ohne das Zuführen von zusätzlichem Brenngas verbrennt. In diesem Fall muss allerdings gewährleistet sein, dass die Fluidreste und Schmutzstoffe in dem Stickstoffgas aus dem Fluidtank 12 Verbrennungseigenschaften haben, die zumindest näherungsweise den Verbrennungseigenschaften von Brenngas entsprechen.It should be noted that in a modified embodiment, the burner 28 is for burning fluid residue or contaminants from the fluid tank 12 can also be a burner which burns nitrogen gas charged with fluid residues or contaminants without supplying additional fuel gas. In this case, however, it must be ensured that the fluid residues and contaminants in the nitrogen gas from the fluid tank 12 have combustion characteristics at least approximately corresponding to the combustion characteristics of fuel gas.

Der Brenner 28 erzeugt dabei einen Heißgasstrahl, der über einen Heißgaskanal 34 zu einer Gasturbine 36 geleitet wird. In der Gasturbine 36 wird die thermische Energie des mit dem Brenner 28 erzeugten Heißgases in kinetische Energie gewandelt, die dann auf einen mit der Gasturbine bewegungsgekoppelten Verdichter 38 und einen elektrischen Generator 40 übertragen wird. Der Verdichter dient für das Verdichten von Ansaugluft, die dem Brenner 28 durch einen Ansaugluftkanal 42 zugeführt wird. Mittels des elektrischen Generators 40 kann für ein nicht weiter dargestelltes Leitungsnetz mit elektrischen Verbrauchern elektrische Energie bereitgestellt werden.The burner 28 thereby generates a hot gas jet, which is conducted via a hot gas duct 34 to a gas turbine 36. In the gas turbine 36, the thermal energy of the hot gas generated by the burner 28 is converted into kinetic energy, which is then transferred to a compressor 38 motion-coupled to the gas turbine and an electric generator 40. The compressor is for compressing intake air which is supplied to the burner 28 through an intake air passage 42. By means of the electric generator 40 electrical energy can be provided for a not further illustrated line network with electrical consumers.

Das Abgas der Gasturbine 36 ist durch einen Abgaskanal 44 geführt. Für das Übertragen von Wärme aus dem Abgas der Gasturbine 36 auf die dem Brenner 28 zugeführte Ansaugluft enthält das Turbinensystem 26 einen Wärmetauscher 46, der Wärme aus dem Abgas der Gasturbine 36 auf die dem Brenner 28 zugeführte verdichtete Verbrennungsluft überträgt.The exhaust gas of the gas turbine 36 is guided through an exhaust passage 44. For transferring heat from the exhaust gas of the gas turbine 36 to the intake air supplied to the burner 28, the turbine system 26 includes a heat exchanger 46 that transfers heat from the exhaust gas of the gas turbine 36 to the compressed combustion air supplied to the burner 28.

Der Abgaskanal 42 des Turbinensystems 26 ist an einen Wärmetauscher 48 angeschlossen. Der Wärmetauscher 48 dient für das Konditionieren von Stickstoffgas aus dem Druckbehälter 20, das durch die Leitung 22 dem Fluidtank 12 für das Spülen von dessen Innenraum zugeführt wird. Der Wärmetauscher 48 ist für das Erwärmen von dem Druckbehälter 20 zugeführtem Stickstoffgas ausgelegt. Mittels des Wärmetauschers 48 ist es möglich, das Stickstoffgas aus dem Druckbehälter 20 von der Umgebungstemperatur auf bis zu 600°C aufzuheizen.The exhaust passage 42 of the turbine system 26 is connected to a heat exchanger 48. The heat exchanger 48 is for conditioning nitrogen gas from the pressure vessel 20, which is supplied through the conduit 22 to the fluid tank 12 for purging from the interior thereof. The heat exchanger 48 is designed for heating nitrogen gas supplied from the pressure vessel 20. By means of the heat exchanger 48, it is possible to heat the nitrogen gas from the pressure vessel 20 from the ambient temperature up to 600 ° C.

Indem der Fluidtank 12 mit aufgeheiztem Stickstoffgas gespült wird, lässt sich erreichen, dass mit einer vergleichsweise geringen Menge von Spülgas ein Fluidtank 12 mit einem großen Innenraumvolumen, wie dies z.B. bei den Fluidtanks von Eisenbahn-Kesselwagen, Tanklastwagen und Schiffen der Fall ist, wo Innenraumvolumina von bis zu 700m3 nicht ungewöhnlich sind, gespült werden kann. Das Konditionieren des in einen Fluidtank 12 eingeleiteten Primärfluids bewirkt dabei nicht nur, dass in dem Innenraum eines Fluidtanks 12 angelagerte Schmutzstoffe sich lösen, sondern auch, dass in einem Fluidtank 12 aufgenommenes Restfluid nicht nur mit dem Primärfluid verwirbelt, sondern durch die Wärmeübertragung größtenteils in einen gasförmigen Aggregatszustand überführt werden kann.By flushing the fluid tank 12 with heated nitrogen gas, it can be achieved that with a comparatively small amount of purge gas, a fluid tank 12 having a large internal volume, such as rail tank cars, tank trucks and ships fluid tanks, has interior volumes of up to 700m 3 are not uncommon, can be rinsed. The conditioning of the introduced into a fluid tank 12 primary fluid thereby not only causes dissolved in the interior of a fluid tank 12 contaminants, but also that in a fluid tank 12 recorded residual fluid swirled not only with the primary fluid, but by the heat transfer mostly in one gaseous state of aggregation can be transferred.

Das beim Spülen eines Fluidtanks 12 über die Leitung 30 mit Schmutzstoffen ausgetragene Sekundärfluid wird in dem Brenner 28 des Turbinensystems 26 mit verdichteter Verbrennungsluft unter Zufuhr von Brenngas chemisch umgesetzt. Der Brenner 28 wirkt so als eine Einrichtung für das chemische Umsetzen von Sekundärfluid in Form von Primärfluid und Restfluid und Schmutzstoffen aus dem Fluidtank 12 unter Freisetzen von Wärme.The discharged during flushing of a fluid tank 12 via the line 30 with contaminants secondary fluid is chemically reacted in the burner 28 of the turbine system 26 with compressed combustion air with the supply of fuel gas. Burner 28 thus acts as a means for chemically reacting secondary fluid in the form of primary fluid and residual fluid and contaminants from fluid tank 12 to release heat.

Mittels der Anlage 100 kann das Primärfluid durch den Fluidtank 112 zum Teil in einem Kreislauf geführt werden, so dass es diesen mehrfach durchsetzt. In einer modifizierten Ausführungsform der Anlage 100 kann anstelle der Saugfördereinheit 131 oder zusätzlich zu dieser in der Leitung 122 eine als Pumpe oder Verdichterstufe ausgebildete Druckfördereinheit vorgesehen sein.In contrast to the system 10 off Fig. 1 There are 100 in the plant Fig. 2 a conduit section 150 which connects the secondary fluid discharge line 130 from the fluid tank 112 to the primary fluid supply line 122 in the fluid tank 112. By means of the system 100, the primary fluid can be partially circulated through the fluid tank 112, so that it passes through it several times. In a modified embodiment of the system 100, instead of the Saugfördereinheit 131 or additionally be provided for this in the line 122 designed as a pump or compressor stage pressure conveying unit.

Wasser zu erwärmen oder Wasserdampf zu erhitzen, mit dem eine entsprechende Oberfläche eines Fluidtanks 12, 112 beaufschlagt wird.It should be noted that the hot exhaust gas of the turbine system 26, 126 in the systems 10, 100 can also be used to heat the fluid tank 12, 112 to be cleaned from the outside. For this purpose, it is possible to pressurize a fluid tank 12, 112 from the outside with hot exhaust gas flowing out of the exhaust gas duct 44, 144 from the gas turbine 36, 136 or with the residual heat contained in this exhaust gas, e.g. To heat water or steam to heat, with which a corresponding surface of a fluid tank 12, 112 is acted upon.
