Verfahren und eine Vorrichtung zum Bereitstellen von See- und/oder MeerwasserMethod and device for providing sea and / or sea water
Die Erfindung betrifft Verfahren und eine Vorrichtung zum Bereitstellen von See- und/oder Meerwasser, wobei das See- und/oder Meerwasser vorzugsweise als Kühl- und/oder Heizmedium für unterschiedlichste Prozesse verwendet wird.The invention relates to methods and a device for providing sea and / or sea water, the sea and / or sea water preferably being used as a cooling and / or heating medium for a wide variety of processes.
Prinzipiell kann das gemäß dem erfindungsgemäßen Verfahren bereitgestellte See- und/oder Meerwasser für jeden beliebigen Prozeß bzw. Anwendungszweck als Kühl- und/oder Heizmedium, sei es für Kraftwerke, Kernkraftwerke, petrochemische Anlagen, Raffinerien, Erdgasverflüssigungsanlagen, etc. verwendet werden. Bei der Verflüssigung von Erdgas werden große Mengen an Kühlmedien benötigt. Gegenwärtig sind sowohl sog. onshore- als offshore-Erdgasverflüssigungsaniagen mit einem der nachfolgenden Kühlsysteme ausgestattet:In principle, the seawater and / or seawater provided according to the method according to the invention can be used for any process or application as cooling and / or heating medium, be it for power plants, nuclear power plants, petrochemical plants, refineries, natural gas liquefaction plants, etc. Large quantities of cooling media are required for the liquefaction of natural gas. At present, both so-called onshore and offshore natural gas liquefaction systems are equipped with one of the following cooling systems:
LuftkühlsystemAir cooling system
Kühlturm-System direktes Meerwasser-System indirektes Meerwasser-SystemCooling tower system direct sea water system indirect sea water system
Für die beiden letztgenannten Systeme ist es von Vorteil, wenn See- und/oder Meerwasser mit möglichst geringer Temperatur, d. h. < 15°C, zur Verfügung steht. Oftmals ist es jedoch der Fall, daß die Temperaturen der oberen Schichten eines Sees oder Meeres zu warm sind, um als Kühlmedien verwendet werden zu können. Hingegen weist das See- oder Meerwasser aus größeren Tiefe die erforderliche geringe Temperatur auf.For the latter two systems, it is advantageous if sea and / or sea water with the lowest possible temperature, ie. H. <15 ° C, is available. However, it is often the case that the temperatures of the upper layers of a lake or sea are too warm to be used as cooling media. On the other hand, the sea or sea water has the required low temperature from a greater depth.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren sowie eine Vorrichtung zum Bereitstellen von See- und/oder Meerwasser anzugeben, mit dem ein energiefreier Transport von See- und/oder Meerwasser aus großer Wassertiefe realisiert werden kann.The object of the present invention is to provide a method and a device for providing sea and / or sea water, with which an energy-free transport of sea and / or sea water from a great depth of water can be realized.
Dies wird gemäß dem erfindungsgemäßen Verfahren zum Bereitstellen von See- und/oder Meerwasser dadurch erreicht, daß das See- und/oder Meerwasser mittels des Siphonprinzips hochgepumpt wird. Die erfindungsgemäße Vorrichtung zum Bereitstellen von See- und/oder Meerwasser umfaßtThis is achieved according to the inventive method for providing sea and / or sea water in that the sea and / or sea water is pumped up by means of the siphon principle. The inventive device for providing sea and / or sea water comprises
a) wenigstens eine See- und/oder Meerwasserentnahmeleitung (1 , 2), deren Einlaßöffnung in einer Tiefe h 3 unter dem See- oder Meeresspiegel liegt, deren höchster Punkt in einer Tiefe h 1 unter dem See- oder Meeresspiegel liegt, und deren Auslaßöffnung in einer Tiefe h 2 unter dem See- oder Meeresspiegel liegt, wobei h 1 < h 2 < h 3,a) at least one sea and / or sea water extraction line (1, 2), the inlet opening of which is at a depth h 3 below sea or sea level, the highest point of which is at a depth h 1 of sea or sea level, and the outlet opening of which at a depth h 2 below sea or sea level, where h 1 <h 2 <h 3,
b) wenigstens ein Becken, in der die See- und/oder Meerwasserentnahmeleitung (1 , 2) mündet, undb) at least one basin in which the sea and / or sea water extraction line (1, 2) opens, and
c) Mittel zum Regeln (a, b) des Wasserstandes in dem Becken.c) Means for regulating (a, b) the water level in the pool.
Das erfindungsgemäße Verfahren, die erfindungsgemäße Vorrichtung sowie weitere Ausgestaltungen des- bzw. derselben, die Gegenstände von Unteransprüchen darstellen, seien anhand der Figuren 1 bis 4 näher erläutert.The method according to the invention, the device according to the invention and further refinements of the same or the same, which are the subject of subclaims, are explained in more detail with reference to FIGS. 1 to 4.
Hierbei zeigen die Figuren 1 und 2 die Anwendung des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Vorrichtung bei einem sog. onshore- Erdgasverfiüssigungsprozeß, während die Figuren 3 und 4 - jeweils in Verbindung mit Figur 2 - die Verwendung des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Vorrichtung bei einem sog. offshore-Verflüssigungsprozeß zeigen.1 and 2 show the application of the method and the device according to the invention in a so-called onshore natural gas liquefaction process, while FIGS. 3 and 4 - each in conjunction with FIG. 2 - show the use of the method and the device according to the invention show a so-called offshore liquefaction process.
Über eine Entnahmeleitung bzw. Pipeline 1 - im folgenden nurmehr Entnahmeleitung genannt - wird das See- oder Meerwasser aus einer Tiefe h 3, die relativ zu dem Seebzw. Meeresspiegel 11 gemessen wird, entnommen. See- oder Meerwasser aus einer Tiefe h 3 bis zu einigen hundert Metern weist eine gleichmäßige Temperatur zwischen 4 und 15°C auf. Die Entnahmeleitung 1 besteht aus einem Polymer-Kunststoff, wie z.B. Polyethylen, PVC, oder mit Glasfieber verstärkter Polyester. Über die Entnahmeleitung 1 wird das See- oder Meerwasser bis auf eine Tiefe h 1 unterhalb des See- bzw. Meeresspiegels 11 geführt.Via an extraction line or pipeline 1 - hereinafter referred to as the extraction line - the sea or sea water from a depth h 3, which is relative to the Seebzw. Sea level 11 is measured, taken. Sea or sea water from a depth h 3 up to a few hundred meters has a uniform temperature between 4 and 15 ° C. The extraction line 1 consists of a polymer plastic, such as Polyethylene, PVC, or polyester reinforced with glass fever. The sea or sea water is led to a depth h 1 below the sea or sea level 11 via the extraction line 1.
Der See- bzw. Meerwassereintritt der Entnahmeleitung 1 ist mit einem in der Figur 1 nicht dargestellten Filter versehen, der verhindert, daß See- oder Meeresfauna und/oder -flora in die Entnahmeleitung 1 gelangt. Um das Wachstum einer Fauna und/oder Flora innerhalb der Entnahmeleitung 1 zu beschränken bzw. zu behindern, kann über eine Leitung 8 ein geeignetes Gegenmittel, wie z. B. Hypochlohte, in die Entnahmeleitung 1 eingebracht werden. Aus diesem Grunde ist die Entnahmeleitung 1 mit einer zusätzlichen, vorzugsweise in der Entnahmeleitung 1 geführten, kleineren Leitung, über die das Gegenmittel gefördert wird, versehen.The sea or sea water inlet of the extraction line 1 is provided with a filter, not shown in FIG. 1, which prevents sea or marine fauna and / or flora reaches the extraction line 1. In order to restrict or hinder the growth of a fauna and / or flora within the extraction line 1, a suitable antidote such as, for. B. hypochlorite, are introduced into the extraction line 1. For this reason, the extraction line 1 is provided with an additional, smaller line, preferably guided in the extraction line 1, via which the antidote is conveyed.
Die Entnahmeleitung 1 ist mittels geeigneter Vorrichtungen 12, wie z. B. Zementblöcken bzw. -stützen, am See- oder Meeresgrund 13 befestigt. Der Wärmeeintrag aus dem umgebenden See- bzw. Meerwasser ist aufgrund der o.g. gewählten Materialien gering.The extraction line 1 is by means of suitable devices 12, such as. B. cement blocks or supports, attached to the lake or sea bottom 13. The heat input from the surrounding sea or sea water is due to the above selected materials low.
Über ein Notfallventil a wird das See- oder Meerwasser über Leitung 2 in ein - lediglich in der Figur 2 im Detail dargestellten - "Becken" geführt. Unter dem Begriff "Becken" ist sowohl ein Becken im eigentlichen Sinne des Wortes zu verstehen als auch, wie in den Figuren 3 und 4 ersichtlich, eine Räumlichkeit innerhalb z. B. einer Bohr- bzw. Förderinsel (Figur 3) oder eines Schiffes (Figur 4). Das bereits erwähnte Notfallventil a dient der Verhinderung der Überflutung der Becken durch See- oder Meerwasser bei einer Notfallsituation.Via an emergency valve a, the sea or sea water is led via line 2 into a “basin” - only shown in detail in FIG. 2. The term "basin" is to be understood both as a basin in the true sense of the word and, as can be seen in FIGS. 3 and 4, a space within z. B. a drilling or production island (Figure 3) or a ship (Figure 4). The already mentioned emergency valve a serves to prevent the pool from being flooded by sea or sea water in an emergency situation.
Das untere Ende der Leitung 2 befindet sich in einer Tiefe h 2 unterhalb des See- bzw. Meeresspiegels 11. Während die Tiefe h 1 typischerweise zwischen 2 und 3 m beträgt, wird die Tiefe h 2 in einem Bereich zwischen 5 und 15 m unterhalb des See- bzw. Meeresspiegels 11 gewählt. Dadurch wird der Druckabfall innerhalb der Entnahmeleitung 1 kompensiert und das über die Entnahmeleitung 1 entnommene See- oder Meerwasser strömt, ohne daß der Einsatz einer Pumpe notwendig wäre, in das Becken. Der Stand des See- oder Meerwassers in dem Becken ist selbstregelnd. Allerdings kann alternativ mittels eines Regelventils b, das mit einer Meßvorrichtung 3 für den Wasserpegel in der Becken verbunden ist (dargestellt durch die strichpunktierte Linie), wird der Pegelstand des See- oder Meerwassers 4 innerhalb des Beckens geregelt.The lower end of the line 2 is at a depth h 2 below the sea or sea level 11. While the depth h 1 is typically between 2 and 3 m, the depth h 2 is in a range between 5 and 15 m below the Sea or sea level 11 selected. As a result, the pressure drop within the extraction line 1 is compensated for and the sea or sea water withdrawn via the extraction line 1 flows into the basin without the need for a pump. The level of sea or sea water in the pool is self-regulating. However, alternatively, by means of a control valve b, which is connected to a measuring device 3 for the water level in the basin (represented by the dash-dotted line), the level of the sea or sea water 4 is regulated within the basin.
Die Abmessungen des in der Figur 2 dargestellten Beckens sind sowohl vom benötigten Platzbedarfs des Equipments - auf das im folgenden noch näher eingegangen wird - innerhalb des Beckens, als auch von dem Erfordernis des Ausgleichs des Druckverlustes innerhalb der Entnahmeleitung 1 abhängig. Dies bedeutet, daß bei einer entsprechenden Tiefe h 3, in die die Entnahmeleitung 1 hinabreicht, eine entsprechende Tiefe h 2 zur Kompensation des Druckverlustes innerhalb der Entnahmeleitung 1 zu wählen ist.The dimensions of the basin shown in FIG. 2 depend both on the space required for the equipment - which will be discussed in more detail below - within the basin, and on the need to compensate for the pressure loss within the extraction line 1. This means that at a corresponding depth h 3 into which the extraction line 1 sufficient to choose a corresponding depth h 2 to compensate for the pressure loss within the extraction line 1.
Innerhalb des Beckens ist eine Reinigungsvorrichtung 5 vorgesehen, bei der es sich vorzugsweise um einen rotierenden Korbfilter oder Korbrechen, der mögliche Partikel von einem Eintritt in das noch zu beschreibende Kühlsystem abhält, handelt. Mittels wenigstens einer Pumpe 7 wird das See- oder Meerwasser über Leitung 6 den Wärmetauschern 9, wie sie in der Figur 1 dargestellt sind, mit dem benötigten Druck, typischerweise zwischen 2 und 5 bar, zugeführt. In diesen Wärmetauschern 9 - wobei es sich unter Umständen auch um lediglich einen Wärmetauscher handeln kann, wird das gepumpte See- oder Meerwasser gegen ein oder mehrere abzukühlende Medien angewärmt. Prinzipiell kann das gepumpte See- oder Meerwasser bzw. ein Teilstrom desselben selbstverständlich auch zum Anwärmen von Medien, die eine niedrigere Temperatur als das See- oder Meerwasser aufweisen, verwendet werden.A cleaning device 5 is provided within the basin, which is preferably a rotating basket filter or basket rake that prevents possible particles from entering the cooling system to be described. By means of at least one pump 7, the sea or sea water is fed via line 6 to the heat exchangers 9, as shown in FIG. 1, with the required pressure, typically between 2 and 5 bar. In these heat exchangers 9 - which may also be just one heat exchanger, the pumped sea or sea water is warmed against one or more media to be cooled. In principle, the pumped sea or sea water or a partial flow of the same can of course also be used for heating media which have a lower temperature than the sea or sea water.
Neben der erwähnten Abkühlung von z. B. zu verflüssigendem Erdgas kann das Seeoder Meerwasser auch der Abkühlung der Verbrennungsluft von Gasturbinen dienen. Durch eine derartige Abkühlung der Verbrennungsluft wird die Leistung der Gasturbinen erhöht, was eine Erhöhung der Produktionskapazität zur Folge hat.In addition to the cooling of z. B. natural gas to be liquefied, the sea or sea water can also be used to cool the combustion air of gas turbines. Cooling the combustion air in this way increases the power of the gas turbines, which results in an increase in the production capacity.
Nach erfolgter Kühlung und/oder Erwärmung des bzw. der zu kühlenden und/oder anzuwärmenden Medien in dem oder den Wärmetauschern 9 wird das erwärmte und/oder abgekühlte See- oder Meerwasser über Leitung 10 wieder in den See bzw. das Meer zurückgeführt. Die Rückführleitung 10 besteht im wesentlichen aus den gleichen Materialien wie die Entnahmeleitung 1. Die Rückführleitung 10 reicht bis zu einer Tiefe h 4, die vorzugsweise zwischen 10 und 30 m beträgt, unterhalb des Seebzw. Meeresspiegels. Am Ausgang dieser Rückführleitung 10 ist im Regelfall ebenfalls eine in der Figur 1 nicht dargestellte Schutzvorrichtung, die das Eindringen von Seeoder Meeresfauna und/oder -flora verhindert, vorgesehen.After cooling and / or heating of the media or media to be cooled and / or heated in the heat exchanger (s) 9, the heated and / or cooled sea or sea water is returned via line 10 to the lake or the sea. The return line 10 consists essentially of the same materials as the extraction line 1. The return line 10 extends to a depth h 4, which is preferably between 10 and 30 m, below the lake or. Sea level. At the exit of this return line 10, a protective device, which is not shown in FIG. 1 and which prevents the ingress of sea or marine fauna and / or flora, is generally also provided.
In der Figur 3 ist eine sog. offshore-Anwendung des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Vorrichtung bei einer Bohr- bzw. Förderinsel dargestellt. Das in der Figur 2 dargestellte Becken ist hierbei z. B. an einer der Stelzen der Bohrbzw. Förderinsel unterhalb des Meerwasserspiegels vorzusehen.FIG. 3 shows a so-called offshore application of the method according to the invention or the device according to the invention in a drilling or production island. The basin shown in Figure 2 is z. B. on one of the stilts of Bohrbzw. To provide a production island below the sea water level.
Wie in der Figur 4 dargestellt, können das erfindungsgemäße Verfahren sowie die erfindungsgemäße Vorrichtung ebenfalls z. B. auf einem Tankschiff für verflüssigtes Erdgas, das einen Erdgasverflüssiger aufweist, angewendet werden. Das in der Figur 2 dargestellte Becken ist in diesem Falle innerhalb des Schiffes, jedoch unterhalb des Meerwasserspiegels vorzusehen.As shown in Figure 4, the inventive method and the inventive device can also z. B. on a tanker for liquefied Natural gas containing a natural gas liquefier can be used. In this case, the basin shown in FIG. 2 is to be provided inside the ship, but below the sea water level.
Das erfindungsgemäße Verfahren sowie die erfindungsgemäße Vorrichtung sind vor allem dann vorteilhaft anwendbar, wenn die Oberflächentemperatur des Wassers relativ hoch ist. Auch im Hinblick auf ökologische Gesichtspunkte weisen das erfindungsgemäße Verfahren sowie die erfindungsgemäße Vorrichtung Vorteile gegenüber den zum Stand der Technik zählenden Verfahren und Vorrichtungen auf, da die Temperaturdifferenz zwischen der Oberfiächentemperatur und der Temperatur des zurückgeführten Wassers vergleichsweise gering ist. Desweiteren hat die Verwendung von kälterem Wasser als Kühl- und/oder Heizmedium den Vorteil, daß aufgrund der niedrigeren Wassertemperatur sowohl die Korrosion als auch die Verschmutzung innerhalb der Leitungen und Wärmetauscher verlangsamt bzw. reduziert werden.The method according to the invention and the device according to the invention can be used advantageously in particular when the surface temperature of the water is relatively high. The method according to the invention and the device according to the invention also have advantages over the methods and devices belonging to the prior art, since the temperature difference between the surface temperature and the temperature of the returned water is comparatively small. Furthermore, the use of colder water as a cooling and / or heating medium has the advantage that both the corrosion and the pollution within the lines and heat exchangers are slowed down or reduced due to the lower water temperature.
Mittels des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Vorrichtung läßt sich bei bestehenden Anlagen die Produktionskapazität erhöhen, während bei Neuanlagen eine deutliche Reduzierung der Investitionskosten erzielt werden kann. By means of the method according to the invention or the device according to the invention, the production capacity can be increased in existing systems, while a significant reduction in investment costs can be achieved in new systems.
