BeschreibungDescription
Die Erfindung betrifft ein System zur Entladung von Gastankschiffen, insbesondere für die Löschung unter Druck verflüssigter Gase.The invention relates to a system for unloading gas tankers, in particular for unloading gases liquefied under pressure.
Die Druckbehälter der Gastankschiffe können üblicherweise auf zwei verschiedene Arten geleert werden. In den Tanks befindet sich unter Druck verflüssigtes Gas in zwei Phasen. Einer flüssigen und einer gasförmigen Phase. Die erste Möglichkeit zur Entleerung der Behälter besteht darin, den Druck in den Behältern durch Zuführung von Gas im gasförmigen Aggregatzustand zu erhöhen und somit Gas im flüssigen Aggregatzustand zu einer Förderpumpe zu drücken. Wesentliches Merkmal einer solchen Anlage ist das Vorhandensein eines Gaskompressors zur Druckerhöhung und einer Boosterpumpe die meist zentral an Deck angeordnet ist.The pressure vessels of gas tankers can usually be emptied in two different ways. The tanks contain liquefied gas under pressure in two phases: a liquid and a gaseous phase. The first way to empty the containers is to increase the pressure in the containers by adding gas in the gaseous state and thus press gas in the liquid state to a feed pump. The key feature of such a system is the presence of a gas compressor to increase the pressure and a booster pump, which is usually located centrally on deck.
Die zweite Möglichkeit zur Entleerung der Behälter ist die Verwendung von Tauchpumpen. Hier sind die Pumpen direkt in der Flüssigphase installiert und fördern ohne zusätzliche Zuführung von Gas das Produkt aus den Tanks. Wesentliches Merkmal ist hier, dass jeder Behälter mit einer Pumpe ausgestattet werden muß. Die Aufgabe der Erfindung besteht darin die bekannten Systeme zur Entleerung von Druckbehältern auf Gastankschiffen zu verbessern.The second option for emptying the containers is to use submersible pumps. Here, the pumps are installed directly in the liquid phase and pump the product out of the tanks without additional gas supply. The key feature here is that each container must be equipped with a pump. The aim of the invention is to improve the known systems for emptying pressure vessels on gas tankers.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung ergeben sich aus den zugehörigen Ansprüchen 2 bis 5.According to the invention, this object is achieved by the features of claim 1. Advantageous embodiments of the device according to the invention emerge from the associated claims 2 to 5.
Die Erfindung beinhaltet demnach System zur Entladung von Gastankschiffen, insbesondere zur Löschung unter Druck verflüssigter Gase, wobei das System mindestens zwei auf dem Schiff angeordnete aus Druckbehältern bestehende Ladetanks umfasst, wobei mindestens ein Ladetank mit einer Pumpe ausgestattet ist und mindestens ein weiterer Ladetank ohne Pumpe vorgesehen ist, wobei von einem Tank eine Saugleitung für eine aus dem Tank abzusaugende Gasphase abgeht, die über einen Kompressor und einer Druckleitung für das verdichtete Gas mit dem anderen Tank verbunden ist. Ferner ist eine Leitung zur Ableitung einer flüssigen Phase vomThe invention therefore includes a system for unloading gas tankers, in particular for unloading gases liquefied under pressure, wherein the system comprises at least two cargo tanks arranged on the ship consisting of pressure vessels, wherein at least one cargo tank is equipped with a pump and at least one further cargo tank is provided without a pump, wherein a suction line for a gas phase to be sucked out of the tank extends from one tank, which is connected to the other tank via a compressor and a pressure line for the compressed gas. Furthermore, a line for discharging a liquid phase from the
zweiten Tank in den ersten Tank vorgesehen, wobei am ersten Tank eine Leitung zur Förderung der Flüssigkeit durch die Pumpe an eine Landanlage vorgesehen ist. Nach einem besonderen Merkmal der Erfindung können auf dem Schiff mehrere Tanks der ersten Art mit einer beliebigen Anzahl Ladetanks der anderen Art kombiniert sein. Die Behälter der ersten Art sind vorzugsweise vakuumfest ausgebildet. Nach einem weiteren Merkmal dient der Ladetank der ersten Art als Gasspender für den Kompressor. Die Pumpe ist bevorzugt als Tauchpumpe ausgeführt.second tank in the first tank, wherein a line is provided on the first tank for conveying the liquid through the pump to a land facility. According to a special feature of the invention, several tanks of the first type can be combined on the ship with any number of cargo tanks of the other type. The containers of the first type are preferably designed to be vacuum-tight. According to a further feature, the cargo tank of the first type serves as a gas dispenser for the compressor. The pump is preferably designed as a submersible pump.
Die vorliegende Erfindung besteht demnach in einer neuen Kombination an sich bekannter Anordnungen. Dabei wird mindestens ein Tank mit einer Tauchpumpe ausgerüstet. Die nicht mit Pumpen ausgerüsteten Behälter werden mittels der o.a. Drukkerhöhung in Behälter mit Tauchpumpen geleert. Dadurch wird eine Einsparung in der Pumpeninvestition sowie eine größere Flexibilität erreicht.The present invention therefore consists of a new combination of known arrangements. At least one tank is equipped with a submersible pump. The containers not equipped with pumps are emptied into containers with submersible pumps by means of the above-mentioned pressure increase. This results in savings in pump investment and greater flexibility.
Die Erfindung soll anhand der nachfolgenden Beschreibung von bevorzugten Ausführungsbeispielen unter Bezugnahme auf der zugehörigen Figur näher erläutert werden. Es zeigen:The invention will be explained in more detail in the following description of preferred embodiments with reference to the accompanying figure. Shown are:
Figur: 1 ein System zur Entladung von Gastankschiffen in schematischer Darstellung. Figure 1: A system for unloading gas tankers in a schematic representation.
Das erfindungsgemäße System besteht im wesentlichen aus den Komponenten: Ladetank 1 mit Tauchpumpe 3, Ladetank 2, Kompressor 5 und einem Rohrleitungssystem zur Verrohrung.The system according to the invention essentially consists of the following components: cargo tank 1 with submersible pump 3, cargo tank 2, compressor 5 and a pipe system for piping.
In der Figur 1 ist das System dargestellt, welches aus 2 Druckbehältern in Form der Ladetanks 1 und 2 besteht. Das System besteht aus mindestens einem Behälter des Typs 1 kombiniert mit einer beliebigen Anzahl von Behältern des Typs 2. Der Kompressor 5 saugt über eine Saugleitung 4 aus dem Ladetank 1 die Gasphase ab und drückt das verdichtete Gas über die Druckleitung 6 auf den Ladetank 2. In Behälter 2 wird der Druck erhöht, in Behälter 1 abgesenkt. Aufgrund der Druckdifferenz strömt die Flüssigphase aus Behälter 2 über die Flüssigleitung 7 in den Behälter 1 . Aus diesem wird die Flüssigkeit mit einer Pumpe 3 über die Abgabeleitung 8 zu einer Landanlage 9 gefördert. Die Förderung durch die Pumpe 3 kann durch eine Deepwellpumpe ( Pumpe im Tank; Motor außerhalb, über eine durch die Tankwan-Figure 1 shows the system, which consists of 2 pressure vessels in the form of cargo tanks 1 and 2. The system consists of at least one type 1 vessel combined with any number of type 2 vessels. The compressor 5 sucks the gas phase out of the cargo tank 1 via a suction line 4 and presses the compressed gas onto the cargo tank 2 via the pressure line 6. The pressure in vessel 2 is increased and in vessel 1 it is reduced. Due to the pressure difference, the liquid phase flows from vessel 2 via the liquid line 7 into the vessel 1. From there, the liquid is pumped by a pump 3 via the discharge line 8 to a land system 9. The pumping by the pump 3 can be carried out by a deepwell pump (pump in the tank; motor outside, via a through the tank wall).

dung geführte Welle verbunden) oder durch eine Submerged Pump- Tauchmotorpumpe (Pumpe und Antriebsmotor innerhalb des Tanks) erfolgen. Die in der aus Behälter 2 überströmenden Flüssigkeit enthaltene Wärmemenge verhindert die Auskühlung des Behälters 1 durch die entzogene Verdampfungswärme. Die alternativ vakuumfeste Auslegung des Tanks 1 ermöglicht den Betrieb des Systems bei niedrigen Produkttemperaturen. Das Absenken des Behälterinnendrucks unter den atmosphärischen Druck gestattet hierbei dessen Verwendung als sicheren Gasspender für den Kompressor.The pumping can be carried out by a submerged pump (pump and drive motor inside the tank). The amount of heat contained in the liquid flowing out of tank 2 prevents the tank 1 from cooling down due to the extracted heat of evaporation. The alternative vacuum-tight design of tank 1 enables the system to be operated at low product temperatures. Lowering the pressure inside the tank below atmospheric pressure allows it to be used as a safe gas dispenser for the compressor.
