Description
Die Betankungseinrichtung besteht im wesentlichen aus den folgenden Kompo nenten:The refueling device essentially consists of the following compos nenten:
- - Speicherbehälter 20 - Storage tank 20
- - Druckfördertank 19 - Pressure delivery tank 19
- - Ventilbox 80 - valve box 80
- - Befüllschlauch 15 - filling hose 15
- - Kompressorkreislauf- compressor circuit
- - LNG-Konditionierungs- und Druckaufbaueinrichtung- LNG conditioning and pressure build-up facility
Funktionsweise:Functionality:
-
1. Befüllen des Vorlagebehälters
Aus dem Speicherbehälter 20 strömt über Ventil 1, Leitung 16 und Ventil 2 aufgrund der Höhendifferenz LNG in den Druckfördertank 19. Die Gas räume der Behälter 20 und 19 sind durch Öffnen von Ventil 3 kurzge schlossen. Bei einem bestimmten Füllstand im Druckfördertank 19 werden Ventil 1, 2, 3 geschlossen. Die Flüssigkeit im Druckfördertank 19 wird anschließend über Ventil 34 konditioniert, das heißt auf einen bestimmten Dampfdruck gebracht. Hierzu perlt warmes Gas durch die Flüssigkeit und gibt hierbei seine Kondensationswärme an die Flüssigkeit ab. Ist dieser Vorgang abgeschlossen, wird der Druckfördertank 19 auf einen bestimmten Druck aufgedrückt. Bei Erreichen dieses Druckes kann der Betankungsvorgang be ginnen. 1.Fill the storage container
Due to the height difference LNG flows from the storage container 20 via valve 1 , line 16 and valve 2 into the pressure delivery tank 19 . The gas spaces of the containers 20 and 19 are short-circuited by opening valve 3 . At a certain fill level in the pressure delivery tank 19 , valves 1 , 2 , 3 are closed. The liquid in the pressure delivery tank 19 is then conditioned via valve 34 , that is brought to a certain vapor pressure. For this purpose, warm gas bubbles through the liquid and releases its heat of condensation to the liquid. When this process is complete, the pressure delivery tank 19 is pressed to a certain pressure. When this pressure is reached, the refueling process can begin. -
2. Anschließen des Befüllschlauches an das Fahrzeug
Nachdem das Erdungskabel und das Signalübertragungskabel am Fahrzeug an geschlossen sind, kann der Füllschlauch 15 an die Fahrzeugkupplung 100 angekuppelt werden. Sowohl das fahrzeugseitige als auch das tankstellensei tige Kupplungsteil sind selbstabsperrende Kupplungen. Somit entfällt das Spülen des Schlauches 15 mit Inertgas. Beim Kupplungsvorgang wird kein Fremdgas (Luft) mit eingeschlossen.2. Connect the filling hose to the vehicle
After the grounding cable and the signal transmission cable on the vehicle are closed, the filling hose 15 can be coupled to the vehicle coupling 100 . Both the vehicle-side and the petrol station-side coupling part are self-locking couplings. This eliminates the need to purge the hose 15 with inert gas. No extraneous gas (air) is included in the coupling process.

1. Kaltfahren des Schlauches
Über Ventil 4, 5, 6, 7 und 1 strömt Flüssigkeit durch den Schlauch 17, Ventilbox 80, Schlauch 15, Ventilbox 80, Schlauch 18 zuück in die Flüssigphase des Speicherbehälters 20. Die fahrzeugseitigen Ventile 105 und 106 sind geschlossen.1. Cold running the hose
Via valves 4 , 5 , 6 , 7 and 1 , liquid flows through the hose 17 , valve box 80 , hose 15 , valve box 80 , hose 18 back into the liquid phase of the storage container 20 . The vehicle-side valves 105 and 106 are closed. - 2. Bei Erreichen eines eingestellten Temperaturschaltpunktes TIS/95 wird Ventil 7 und 1 geschlossen, das fahrzeugseitige Ventil 105 geöffnet und die Flüssigkeit strömt über Kupplung 16 in den zu befüllenden Fahrzeugtank. Gleichzeitig wird die Füllmenge mittels des Mengenmeßgerätes 85 gemes sen.2. When a set temperature switching point TIS / 95 is reached, valves 7 and 1 are closed, the vehicle-side valve 105 is opened and the liquid flows via coupling 16 into the vehicle tank to be filled. At the same time, the filling quantity is measured by means of the quantity measuring device 85 .

3. Gasrückgang aus dem Fahrzeugtank
Besitzt der Fahrzeugtank einen zu hohen Druck, so kann dieser über Kupplung 16, Schlauch 15, Ventil 8 und 9, Schlauch 18 und Ventil 1 in die Flüssigphase des Speicherbehälters 20 entlastet werden. Hierzu wird am Fahrzeug Ventil 105 geschlossen und Ventil 106 geöffnet. Die hierbei in den Speichertank zurückströmende Menge wird vom Mengenmeßgerät 90 gemessen. Über eine Differenzbildung zwischen Mengenmeßgerät 85 und 90 kann die Nettomenge bestimmt werden, welche in den Fahrzeugbehälter gefüllt wird. Hierdurch wird die Mengenmessung eichfähig.3. Gas decrease from the vehicle tank
If the vehicle tank has too high a pressure, this can be relieved into the liquid phase of the storage container 20 via the coupling 16 , hose 15 , valve 8 and 9 , hose 18 and valve 1 . For this purpose, valve 105 on the vehicle is closed and valve 106 is opened. The quantity flowing back into the storage tank is measured by the quantity measuring device 90 . The difference between the quantity measuring device 85 and 90 can be used to determine the net quantity which is filled into the vehicle container. This enables the quantity measurement to be verified. -
4. Kaltfahren eines warmen Fahrzeugbehälters
Mittels abwechselndem Befüllen (Punkt 2) und Gasrückgang (Punkt 3) eines warmen Fahrzeugbehälters (intermittierender Betankungsbetrieb) kann dieser abgasfrei kaltgefahren und befüllt werden (z. B. bei Inbetriebnahme des Fahr zeugbehälters).4. Cold driving a warm vehicle container
By alternately filling (point 2) and decreasing gas (point 3) a warm vehicle container (intermittent refueling operation), it can be cold-filled and filled without exhaust gases (e.g. when the vehicle container is started up).
- 1. Ventilbox 50 mit integrierten Mengenmeßgeräten 85, 90 für Gas- und Flüssigphase zur Bildung der Netto-Befüllmenge (Eichfähigkeit des Systems, Minimierung des Wärmeeintrages in das Medium durch Mengenmessung).1. Valve box 50 with integrated quantity measuring devices 85 , 90 for gas and liquid phase to form the net filling quantity (calibration capability of the system, minimization of heat input into the medium by quantity measurement).
- 2. Ventilschaltung der Ventilbox, die ein Kaltfahren des Schlauches in gekuppel tem Zustand (Kupplung ist mit Fahrzeug verbunden) zuläßt.2. Valve circuit of the valve box, which cools the hose in coupled condition (clutch is connected to the vehicle).
-
3. Rückführung des Gasrückgangs in die Flüssigphase des Speicherbehälters
Dies ermöglicht ein abgasfreies Betanken des Fahrzeuges sowie ein abgasfrei es Kaltfahren eines auf Umgebungstemperatur befindlichen Fahrzeugbehäl ters. Die Flüssigkeitsmenge im Speichertank ist immer so bemessen, daß kein unerwünschter Druckanstieg im Speicherbehälter 20 durch Aufnahme der Kondensationswärme erfolgt.3. Return of the gas return to the liquid phase of the storage tank
This enables an exhaust-free refueling of the vehicle and an exhaust-free cold driving of a vehicle container located at ambient temperature. The amount of liquid in the storage tank is always such that there is no undesirable increase in pressure in the storage container 20 due to the absorption of the heat of condensation.
Mittels eines Kompressors 29 kann aus der Gasphase des Speicherbehälters 20 Gas (Boil-Off) gezogen werden und in Flaschenbündel 21 gedrückt wer den. Hierdurch wird der Druck im Speicherbehälter 20 abgesenkt und somit dessen Standzeit erhöht.By means of a compressor 29 , gas (boil-off) can be drawn from the gas phase of the storage container 20 and pressed into bottle bundles 21 . This lowers the pressure in the storage container 20 and thus increases its service life.
