- a tank In order to connect lines to a tank, a tank is usually provided with nozzles, are flanged to the lines. For safety reasons, it would be better to weld cables to a tank. In a conventional tank, however, this can not be done regularly in practice. For safety reasons, it is also advisable not to pass lines through a tank bottom or through side walls of the tank. Otherwise, a corresponding leak in the line in the tank area will cause the liquid in the tank to drain due to gravity.

- Storage implies both the meanings “storage”, ie “filling”, as well as “outsourcing”, ie removal, as well as “holding” or "containing”.
- a tank of a means of transport is filled with liquefied gas, such as LNG, by heating the liquefied gas and pumping it into the tank after heating.
- liquefied gas such as LNG
- heating it is meant that stored liquefied gas is not merely pumped from a storage tank into the transport medium tank. Instead, liquefied gas is actively heated from the storage tank and is heated to the transport tank.
- An active heating in the context of the invention is when the liquefied gas originating from the storage tank is supplied with controlled heat, for example by mixing boil-off gas with the liquefied petroleum gas or by heating the liquefied gas originating from the storage tank with a heat exchanger and heating it Heat exchanger enters the transport tank.
- the invention accordingly relates to a method for storing cryogenic liquefied petroleum gas in a tank of a means of transport, in particular a ship, comprising the steps of: removing liquefied gas from a storage tank, in particular from a stationary storage tank, heating the withdrawn liquefied gas, filling the tank of the means of transport the heated LPG by pumping the liquefied gas into the tank of the transport.
- LNG is stored in a storage tank at a temperature of less than -161 0 C, so as to be able to store LNG at normal pressure.
- the storage temperature of LNG in a ship's tank usually also at less than -161 0 C.
- a system for filling and / or emptying a tank of a ship with LNG is provided for carrying out the method, for example with a tank for the tank
- design pressure also called design pressure
- design pressure is at least 5 bar g (bar gauge), preferably at least 10 bar g
- the tank being provided with a cryogenic liquified gas inlet and an outlet for unloading the tank , wherein the inlet comprises means for heating LNG.
- the invention thus also relates to a system for storing cryogenic liquefied petroleum gas for a means of transport, in particular for a ship, comprising: a transport medium tank for storing liquefied gas, an inlet device, for the removal of liquefied gas from a storage tank, in particular from a stationary storage tank, Means for heating the withdrawn liquefied gas, and a filling device for the tank of the means of transport with a pump for pumping the heated liquefied gas into the tank of the means of transport; as well as one
- Means of transport in particular a ship, with such a system.
- the temperature of the liquefied gas present in the transport medium tank is preferably above the boiling point of the liquefied gas at normal pressure.
- liquid gas can be taken immediately after filling, so after refueling about the ship, so as to be able to supply a drive with fuel gas.
- a ship can continue its journey immediately after refueling without having to use a pump for the fuel supply.
- the liquefied gas has been heated by at least 10 0 C so as to arrive at a desired bearing pressure.
- a temperature difference is regularly conducive to immediately a sufficiently high bearing pressure in the
- the bearing pressure in such a ship's tank is preferably at least 3 bar absolute; a pressure of more than 5 bar absolute or even 8 bar absolute can also be beneficial. So before that was the
- gas present in the ship's tank is added to the liquefied gas during filling, which is introduced into the ship's tank.
- the liquefied gas is not only heated, but condensed advantageous in the vessel's tank gas at the same time.
- the supply of the gas is preferably carried out in the supply line, via which the liquefied petroleum gas is pumped into the ship's tank.
- the feed advantageously takes place outside the ship's tank, specifically in a process space. Gas is thus sucked out of the ship's tank via a second line and pressed into the line, via which the liquid gas is pumped into the ship's tank.
- the originating from the ship's tank gas is mixed with the liquefied gas, in particular by means of a z. B. static mixer mixed.
- the mixer is also advantageously located in a process room.
- the LPG Since with the help of the gas located approximately in the vessel tank, the LPG may only be heated by about 0.5 0 C to 1 ° C and a heating of 0.5 0 C to 1 ° C may not be sufficient, the LPG is at a preferred embodiment, at least in addition to a heat exchanger heated.
- the heat exchanger is preferably also outside the ship's tank and in particular in one
- the liquid gas is pumped into it by means of a pump, namely with a pressure which is above the bearing pressure in the tank.
- the bearing pressure in the tank is 3 bar absolute
- the liquefied gas is pumped absolutely into the tank at a pressure of more than 3 bar, for example at a pressure of 4 bar absolute.
- gas originating from the transport medium tank is added to the liquid gas which is pumped into the transport tank, this gas is injected into the liquid gas at a pressure which is above the liquid pressure of the liquefied gas to be heated.
- This gas pressure is, for example, 5 bar absolute (bar a) when the liquid pressure of the liquefied gas to be heated is 4 bar absolute.
- a ship tank In order to be able to fill a ship tank particularly quickly with liquefied gas, it is preferably filled via only one supply line. If liquefied petroleum gas is to be refueled, then only one line (tank line) must be connected and removed after refueling, what the for refueling required time required. The speed with which one
- Transport tank can be filled with LPG is limited only by the cross section of the tank line and the pressure at which the LPG is pumped into the tank. It is therefore possible to pump liquid gas into the tank at high speed, so that the means of transport can be refueled quickly.
- a transport medium tank in particular a ship tank, in which heated LPG is located, is preferably taken from LPG by opening a valve of a withdrawal line.
- the overpressure in the transport tank then ensures that the liquid is pushed out through the withdrawal line out of the tank and can be supplied to the drive as the ship.
- the extraction line extends approximately in a ship, preferably through a vessel tank top through to the bottom of the
- valves with which a sampling line is to be closed or opened housed in a pressure vessel.
- the relevant valves are adjacent to the transport tank.
- valves If a leak occurs behind the valves when viewed from the tank, the valves are closed immediately. It can then get no more liquid gas from a tank in the lines of the system and leak through a leak. If, however, a leak occurs in a valve which is arranged adjacent to the tank and through which a withdrawal line can be opened or closed, there is no possibility of being able to close the withdrawal line and prevent further escape of liquefied gas. This difficulty is solved by the additional pressure vessel, which shields such a valve to the outside. If a leak occurs in such a valve, then the extraction line can not be closed. The leaking liquefied gas then passes into the pressure vessel, which then ensures that liquefied gas can not damage the ship beyond that.
- the valve of the extraction line is located advantageously outside the transport tank, in particular of the ship's tank, in particular in a process space.
- the extraction line advantageously has a relatively thin cross-section compared to the conduit through which the transporting agent tank is filled.
- a large cross-section of the line, through which the tank is filled, advantageously allows fast refueling of a ship. Since the removal is much slower, this is sufficient for a small cross section for this
- the withdrawal conduit is disposed within the conduit through which liquid gas is pumped approximately into the vessel's tank. This reduces the number of lines leading into the tank separated from each other. The risk of a leak is thus minimized further.
- the double tube thus provided extends advantageously only up to the top of the tank. All that is needed is the bottom of the tank
- the ship's tank is provided with a line through which gas can be removed from it.
- the line therefore preferably flows into the vessel tank from above and does not extend further into the tank.
- the conduit is connected to a heat exchanger and preferably also to a compressor to heat and compress the gas so that it can be used to propel the vessel.
- This line therefore always leads to the drive, for example, to be able to use boil-off gas for the drive.
- boil-off gas is used for the drive, then a pressure is initially given by the warm-up during refueling. If necessary, this pressure is either by recirculation of hot gas from a compressor of the system or by suction of gas to
- the said process space is outside the transport tank, in particular the
- Ship tanks arranged. This particular has a preferably made of stainless steel tub.
- the above-mentioned devices which are preferably arranged in the process space, are located in or above the tub. Occurs in these devices, a leak, it is collected leaking liquefied gas from the tub and can not continue to be destructive.
- the process room can also be open but also completely closed.
- the transport tank comprises only two lines which are connected thereto. This reduces the risk of leakage occurring. Preferred are the lines welded to the tank, which is manageable due to the small number of lines in practice. The security is thereby further increased.
- valves of the liquid lines closest to the transport tank are enclosed by a collecting container whose design pressure is higher than that of the respective tank. This greatly minimizes the possibility of leakage of liquid into the process space.
- Such valves are basically remote-controlled.
- lines connected to the transport tank are each provided with an enclosed shut-off valve, for example with the aforementioned remotely controllable valves with collecting container.
- These lines and connections are preferably made fully welded. So it lacks neck, to a line
- Liquefied gas in the vessel tank is at least 3 bar absolute.
- System for filling and / or discharging a tank of a ship with LNG with a tank for the storage of LNG, whose design pressure is at least 5 bar g, preferably at least 10 bar g, the tank having a cryogenic liquified gas inlet and an outlet for discharging the tank, the inlet comprising means for heating LNG.
- the means for heating LNG comprises a heat exchanger and / or means for adding gas from the tank to the LNG pumped into the tank.
- Pressure vessel for opening and closing at least one
- the invention can, as mentioned, not only for ships, but also for the drive of other mobile systems, ie means of transport are used, such as for the propulsion of aircraft or land vehicles. Instead of a ship's tank is then about the tank about an aircraft. Generalizing here is placed on transport tanks.

- the outgoing gas is passed through a heat exchanger 7, in order to heat the gas when needed can.
- the gas is in two compressors 8 introduced, which are able to compress the gas in the desired manner. If inexpensive oil-lubricated compressors 8 are used, the gas is then passed through the oil separator 9. The oil separated here can be returned to the compressors 8. For redundancy reasons, two compressors are provided in order to be able to continue driving in the event of a compressor failure.
- the gas is introduced through a cooler 10 into a buffer volume 11.
- the cooler if necessary, cools the gas to a temperature that is required by the consumer.
- the buffer volume 11 serves to bridge, if in the short term not enough fuel (LPG or Boil-off Gas) can be removed from the tanks 1.
- the gas is either forwarded via the line 12 to the consumer or via the line 13 into the mixer 6 into it.

- the embodiment shown in Figure 2 also still includes level gauge 23. Although there is then a third compound which leads into the tank. But since this is not connected to external lines, this is not a problem and does not hinder the construction of the system further.
- the level indicator of the level gauge is located in the process room. This can also be accommodated in a separate container.
- the present invention can be provided by reducing the pressure in a ship's tank 1 immediately a desired amount of gas, since the pressure prevailing in the tank overpressure for the liquefaction of the gas is needed.
- the bearing pressure in the vessel tank is above the pressure required by the consumer, no compressor is required to provide the gas pressure needed by the consumer. It then suffices a reducing valve, with which the gas pressure can be lowered if necessary suitably. For example, if the bearing pressure in the tank is 6 bar a and requires one
- the ship's tanks 1 can be insulated with insulating material or by vacuum. In-tank pumps are not used because they are not needed.
- the system according to the invention is robust and less susceptible to interference. Wear parts lie outside the tank and are therefore easy to reach without having to go through the tank.
- FIG. 3 shows a flowchart for the essential steps of the invention
- LNG is taken from a stationary storage tank located on land 31. After removal and before LPG is pumped into the tank of a ship, the LPG is heated by means of a heat exchanger 32. After heating, the
- Liquefied petroleum gas is pumped into a tank of the ship to be used as fuel for a propulsion system
