    [0001] The present invention relates to an installation for the delivery and treatment of cryogenic liquid. The invention may relate to any type of cryogenic liquid, that is to say any liquid obtained by cooling at very low temperatures (generally below -100 ° C.) gases (pure or gas mixtures) such as, for example, nitrogen, helium or natural gas (methane). For certain uses of cryogenic liquids, the liquid is stored in a relatively large tank and means are provided for delivering relatively small amounts of liquid into containers, such as a tank of a truck or a cylinder of cryogenic liquid. . There is thus a refueling station with a storage tank and pressurized distribution means adapted to the container to be filled generally comprising a pump for transferring cryogenic liquid from the storage tank to a carboy and / or to carry out a refueling of a vehicle. In the remainder of the description, to lighten the wording, it will be assimilated transfers of liquid (from the tank to for example a carboy or dewar) to a refueling (from the tank to a tank of a vehicle). During this delivery operation (transfer or refueling), the cryogenic liquid may undergo a treatment that will change its pressure and its temperature. Indeed, especially when it comes to refueling a tank of a vehicle, the liquid must be delivered into the tank under conditions of predetermined temperature and pressure, different from the conditions prevailing in the storage tank In a refueling station, lines are used between the storage tank and the container to be filled. Since a pipe has a large surface area relative to its internal volume, a relatively large exchange surface is produced which tends to heat the cryogenic liquid and to vaporize it. In the case of a liquefied natural gas (LNG) refueling station, the gaseous gas can not be released to the open air and the refueling stations then plan to return it to the storage tank. This may be true for other cryogenic products. The gas that is introduced into the storage tank warms the liquid in the tank. The pressure inside the latter increases and when it reaches a predetermined limit, a safety valve opens to allow gas to escape. This gas is usually lost. It is therefore advisable to avoid reaching the maximum permissible pressure in the storage tanks. This problem of vaporization of the cryogenic liquid between the storage tank and the container to be filled is all the more obvious that the delivery facility is little used. Indeed, if the liquid deliveries are spaced in time, all the elements downstream of the storage tank warm up between two deliveries and it is necessary to evacuate the calories that have entered the system. In addition, for the pump and / or any fluid treatment equipment to operate in good conditions, they must work in the liquid phase. It is therefore necessary to cool these equipment before delivering cryogenic liquid.
    [0002] In refueling stations which randomly deliver small quantities of cryogenic liquid, the lines between the storage tank and the container to be filled remain filled with liquid which gradually vaporizes. The more liquid deliveries made are occasional, the more the pipes and other equipment (pump, means used for distribution, etc.) warm up between two delivery operations. Figure 1 illustrates a refueling station of the prior art. A storage tank 2 feeds, for example, a tank 4 to be filled by means of cryogenic equipment most often including a cryogenic pump 6 and another equipment 8 for treating the liquid. A first pipe 10 makes it possible to feed the pump 6 from the storage tank 2 while a second pipe 12 is provided to make a return from the pump 6 to the storage tank 2. The pump 6 also has an outlet supplying the cryogenic liquid treatment equipment 8 before this liquid is sent to the tank 4. A third pipe 14 is provided to return the equipment 8 to the storage tank 2. As illustrated, a first valve V1 is used to control the flow of liquid in the first pipe 10, a second valve V2 makes it possible to control the return of fluid from the pump 6 to the storage tank 2 via the second pipe 12, a valve V30 makes it possible to control supplying the treatment equipment 8 from the pump 6 while a valve V40 regulates the return to the storage tank 2 from the equipment 8. When the system has not realized delight (or any other delivery of liquid, transfer or refueling), it is first necessary to proceed to the cooling of the pump 6 and the equipment 8 before starting to fill the tank 4. A first step provides cooling of pump 6. Valves V1 and V2 are open, while valve V30 is closed. A closed loop between the storage tank 2 and the pump 6 is then performed. The second pipe 12 brings back to the storage tank 2 a mixture of liquid and gas. When the pump 6 is cooled, the valve V30 opens to let the liquid go to the equipment 8. The valve V1 can close gradually while the valve V40 is open to create a circuit between the storage tank 2 and the equipment 8 to allow cooling of the latter. After cooling of the equipment 8, liquid can then fill the reservoir 4. In such a refueling station, when several hours pass between two cryogenic liquid delivery operations, all the liquid remaining in the pipes after the end of the first delivery operation has time to vaporize before the start of the second delivery operation. This leads to significant gas phase gas returns to the storage tank 2.
    [0003] As is apparent from the foregoing, then there are two main sources of heat input into the storage tank: - firstly during the cooling operations of the equipment (pump and other treatment equipment (s) ), heat from this equipment is returned to the storage tank, and - after a refueling operation (or the like), the liquid remaining in the system vaporizes and returns to the storage tank, thereby realizing another source of heating of the liquid stored in the tank.
    [0004] The present invention therefore aims to limit the gaseous input into the storage tank. For this purpose, the present invention proposes a cryogenic liquid delivery installation from a storage tank comprising: cryogenic equipment for delivering and / or treating cryogenic liquid from the storage tank to a container to be filled. According to the present invention, this installation comprises an intermediate chamber that can be supplied with cryogenic liquid from the storage tank without passing through the cryogenic equipment, the cryogenic equipment can be supplied with cryogenic liquid either by the storage tank, or by the intermediate chamber, and a connection for driving fluid leaving the cryogenic equipment to the intermediate chamber. The intermediate chamber provided here can then be used to collect the vapors from a cooling operation of the cryogenic equipment and thus prevent any return of vapors, and therefore heat, to the storage tank. The intermediate chamber can be used for storage of this heat recovered during the cooling operation and be supplied to the container to be filled. In fact, in the vast majority of cases, the containers to be filled must preferably contain a saturated liquid and the heat inputs are less critical at the container to be filled, which is necessarily much smaller than the size of the tank, that 'at the level of the tank. It is proposed that the intermediate chamber is arranged in such a way with respect to the storage tank that cryogenic liquid can be transferred from the storage tank to the intermediate chamber by gravity. Liquid can then be transferred directly from the storage tank to the intermediate chamber without a pump or other transfer equipment. To allow better control including pressure and / or temperature within the intermediate chamber, the latter is advantageously equipped with a cooling system and / or a vaporizer in a closed circuit with the intermediate chamber, the vaporizer being connected upstream to a lower zone of the intermediate enclosure.
    [0005] In an installation according to the present invention, the cryogenic equipment preferably comprises a cryogenic pump. This pump can then be used to transfer liquid to the container to be filled but also to empty the intermediate chamber. An advantageous embodiment then provides that the cryogenic pump is disposed inside the intermediate enclosure. The intermediate chamber then allows both to store cryogenic liquid and maintain the cold pump. A degassing line can be provided to allow degassing of a container to be filled towards the intermediate chamber. In this way, degassing of this container in the direction of the storage tank is avoided. To allow an effective purge at the end of the cryogenic liquid delivery operation, an installation according to the present invention advantageously has a low point between the storage tank and the cryogenic equipment. The idea is then to discharge a maximum of liquid in the pipes of the installation after the delivery of liquid to the storage tank, in still liquid form to minimize the heat input into the tank. An advantageous variant provides that the installation is designed to present downstream of the low point a slope of the same direction towards the container to be filled. The present invention also provides a method for delivering a cryogenic liquid from a storage tank to a container to be filled, through cryogenic equipment for delivering and / or treating cryogenic liquid from the storage tank. to the container to be filled, 25 characterized in that it comprises the following steps: a) partial filling of an intermediate chamber with cryogenic liquid from the storage tank, b) cooling of the cryogenic equipment by feeding the l cryogenic liquid cryogenic equipment and returning the fluid leaving the equipment at least partially in the intermediate chamber, c) after cooling of the cryogenic equipment, delivery of cryogenic liquid to the container to be filled from the intermediate enclosure and / or storage tank.
    [0006] In a method according to the invention, the cryogenic fluid delivery step is for example carried out by adjusting the pressure in the intermediate chamber so as to push cryogenic liquid to the container to be filled.
    [0007] It can also be provided in a method according to the invention that a step of regulating the temperature and / or pressure is carried out in the intermediate chamber after cooling of the cryogenic equipment. Details and advantages of the present invention will become more apparent from the following description, given with reference to the accompanying diagrammatic drawing, in which: FIG. 1 schematically illustrates a cryogenic liquid delivery installation of the prior art, and FIG. 2 schematically illustrates a cryogenic liquid delivery installation according to the present invention.
    [0008] FIG. 2 shows an installation having a structure similar to that of FIG. 1. Similar elements are here again found, which are then designated with the same references as in this FIG. 1. A FIG. storage 2 of cryogenic liquid which feeds a container to be filled (which will be assumed to be a tank 4 throughout the rest of this description) via a cryogenic pump 6 and a cryogenic treatment equipment 8. A first pipe 10 makes it possible to feed the pump 6 from the storage tank 2 while a second pipe 12 is provided to make a return from the pump 6 to the storage tank 2. The pump 6 also has an outlet supplying the cryogenic liquid treatment equipment 8 before this liquid is sent to the tank 4. The storage tank 2 is a cryogenic tank adapted to contain a liquid at a very low temperature such as for example liquefied natural gas, or another gas in liquid form such as nitrogen or hydrogen. Means known to those skilled in the art and not described herein are associated with this storage tank 2 to prevent the pressure inside thereof from exceeding a predefined limit. When the tank contains liquefied natural gas, no gas should be discharged into the atmosphere and suitable means are also provided to prevent unwanted release. The tank 4 to be filled is here for example a tank of a vehicle such as a truck or the like but it could also be for example a container such as a dewar or a cylinder.
    [0009] To deliver cryogenic liquid to the tank 4, it is not necessary to provide a pump such as the pump 6 which is optional. Depending on the desired temperature and pressure conditions at the tank 4, it may be possible to have only equipment 8 adapted for the delivery of cryogenic liquid with the usual components equipping a distribution device as they are known. those skilled in the art and not described in detail here (check valve, pressure regulator, sealing means, ...). The cryogenic equipment 8, and possibly also the pump 6, also generally comprise control and control means. It is also generally provided means for, on the one hand, to adapt the pressure and / or the temperature of the liquid and, on the other hand, to ensure that the pump only admits liquid and that it does not work partially in the gas phase. The pump 6 and the cryogenic equipment 8 are fed from the storage tank 2 by the first pipe 10 which extends towards the tank 4. The second pipe 12 is in turn intended to return the storage tank 2 to the storage tank 2. vapors from the vaporization of the cryogenic liquid within the pump 6. Figure 2 illustrates a return of the second pipe 12 in the lower part of the storage tank 2 but could also provide a return to the top of the latter. As illustrated in FIG. 2, the first pipe 10 comprises a low point 16 (illustrated by a star) disposed between the storage tank 2 and the cryogenic assembly formed by the pump 6 and the cryogenic equipment 8. A valve V1 on the first pipe 10, arranged here between the storage tank 2 and the low point 16, makes it possible to control the flow rate of cryogenic liquid in the first pipe 10. Such a valve may for example be disposed directly at the outlet of the storage tank 2. In most cases, the storage tanks are provided with the origin of such a valve V1 which may be called for example the outlet valve of the tank. Preferably, the low point 16 is connected directly, or only via the valve V1, to the storage tank 2. The first pipe 10 has a constant slope, without rising, between the storage tank 2 and the low point 14. In an advantageous embodiment (not corresponding to the illustrated embodiment), the first pipe 10 may be a vertical pipe from the tank to the low point 16 which is then under the storage tank 2. Downstream of the point 16 down to the tank 4, the first pipe 10 preferably has no relative low point, that is to say that it is always inclined with a slope of the same direction, so that all the liquid content in the first pipe 10 is attracted by gravity to the low point 16. This continuous slope between the low point 16 and the tank 4 is symbolized by an inclined arrow 18 in Figure 2. A valve V2 is also provided on the second conduit e 10 to control and regulate the gas flow to the storage tank 2. Usually, such a valve is disposed near the storage tank 2 and usually equips the original storage tank 2. Note on FIG. 2 the presence of an intermediate chamber 20 forming a buffer between the storage tank 2 and the tank 4. This intermediate enclosure 20 is a cryogenic container intended to contain cryogenic liquid at very low temperature and under predetermined pressure conditions. . In a conventional manner, the cryogenic liquid in the intermediate chamber 20 is in equilibrium with a gaseous phase. The liquid phase is at the bottom of the intermediate chamber 20 and the gas phase at the top.
    [0010] The intermediate chamber 20 may be supplied with cryogenic liquid by a bypass 22 of the first pipe 10 located upstream of the cryogenic pump 6. The flow in this branch 22 is controlled by a valve V3. A network of pipes is provided to allow the evacuation of the cryogenic liquid which vaporizes during the operation of the described system. In an original way, it is proposed to conduct the vapors collected in this network, at least initially, to the intermediate chamber 20.
    [0011] Thus there is first of all a bypass of the second pipe 12, controlled by a valve V4, at the outlet of the pump 6.A valve V5 is provided to control the degassing of the cryogenic equipment 8. It is also planned to return to the intermediate chamber 20 the vapors contained in the tank 4. A valve V10 is provided on the corresponding degassing pipe. The pipes comprising the valves V4, V5 and V10, in the embodiment illustrated in Figure 2, lead to a collector 24 which brings the collected vapors to the bottom of the intermediate chamber 20. These vapors are introduced by a ramp 26 in the liquid in the intermediate chamber 20. Here we could also consider reintroducing the vapors collected in the upper part of the intermediate chamber 20, that is to say in the part of this chamber generally containing fluid in the gas phase. To allow possible degassing of the intermediate chamber 20, a pipe connects the upper part of the intermediate chamber 20 to the storage tank 2. A valve V7 regulates the flow in this pipe. Here again, FIG. 2 represents a pipe opening at the top of the storage tank 2, but it is quite possible here to introduce the fluid in the gas phase essentially coming from the intermediate chamber in the lower part (containing liquid) of the storage tank 2. A vaporizer 28 is associated with the intermediate chamber 20. It is intended to vaporize, when necessary, liquid in the intermediate chamber 20 to reintroduce it under gaseous form. A valve V6 controls the supply of liquid to the vaporizer 28. In FIG. 2 illustrating a preferred embodiment, the gas phase fluid leaving the vaporizer 28 can be reintroduced to the upper part of the intermediate chamber 20, that is, that is to say in the zone thereof intended to contain fluid in gaseous phase, or in the lower part of this chamber, in the zone thereof intended to contain liquid. A valve V8 controls the introduction of the fluid from the vaporizer 28 in the upper part of the intermediate chamber 20 and a valve V9 controls the introduction of the fluid from the vaporizer 28 into the lower part of the intermediate chamber 20. For introduction in the lower part of the intermediate chamber 20, it can be provided that the fluid from the vaporizer 28 is introduced into the manifold 24. The vaporizer 28 can be used to increase the temperature and / or the pressure within the intermediate chamber 20. There is also provided a cooling system 30 illustrated schematically in FIG. 2 to enable the temperature and / or the pressure in the intermediate chamber 20 to be reduced. Finally, the presence of a control valve is noted. V11 between the pump 6 and the equipment 8. The operation of the cryogenic liquid delivery installation described above is for example the following. Before performing a refueling (or transfer) operation, as mentioned above, the system is cooled according to a procedure adapted to the pump 6 and the cryogenic equipment 8. This procedure is intended in particular to ensure proper operation of the pump (and / or other equipment) integrated in the cryogenic equipment. As indicated above, the presence of a pump is here optional and the invention can be implemented without the pump 6. Before putting the pump 6 and the equipment 8 in temperature, it is proposed to transfer cryogenic liquid from the storage tank 2 to the intermediate chamber 20. Preferably, this transfer of liquid is carried out by gravity. The valves V1 and V3 of the system are then open. In order to allow degassing of the system, the valve V2 and V4 and / or the valve V7 are also opened, thus allowing the vapors to return to the storage tank 2. The intermediate enclosure 20 is for example filled approximately halfway, for example between 1/3 and 2/3 of its liquid capacity. To cool the pump 6, liquid is sent into it (liquid can pass through the pump even when it is not started) and the flow out of it, first of all essentially gas then more and more liquid, is sent (via the second pipe 12 and the bypass with the valve V4 and via the manifold 24 and the ramp 26) in the bottom of the intermediate chamber 20. The vapors condense by passing through the liquid while increasing the temperature within the intermediate chamber 20. During this cooling operation of the pump 6, the valves V1 and V4 are open. For degassing of the system, valve V7 is advantageously open. At this point, it is expected that the valve V11 is closed. When the pump 6 is cooled and is in condition for nominal operation, it can then be started. The valve V11 is then open and liquid is sent to the equipment 8 which can be cooled in turn. Valves V1, V11 and V5 are open. As explained above, vapors are condensed within the intermediate chamber 20 and the temperature therein increases. Degassing can be envisaged (valve V7 open).
    [0012] When all the elements are in normal conditions (in particular temperature) of functioning, the refueling of the tank 4 can begin. The preferred embodiment illustrated here provides that the vapors from the degassing of the tank 4 are conducted to the intermediate chamber 20. The valve V10 is then open to allow this degassing.
    [0013] As explained above, when the latter begins, the temperature in the intermediate chamber 20 will then be further increased. The liquid used to fill the tank 4 preferably comes from the intermediate chamber 20. To fill the tank 4, the valve V1 is then closed and valves V3 and V11 open.
    [0014] It may be noted here that if the pressure in the intermediate chamber 20 is sufficient, it is unnecessary to provide a pump to fill the tank 4. It is also possible to start filling the tank 4 without using the pump 6 if the pressure is sufficient then turn on the pump 6 when the pressure in the intermediate chamber drops. It is also possible to use the vaporizer 28 to maintain in the intermediate chamber 20 a sufficient pressure to push the liquid out of the intermediate chamber 20. In this case, the pump 6 can be used at the end of refueling for empty the intermediate chamber. It will be taken care to close the valve V3 sufficiently early to avoid any injection of gas phase fluid in the pump 6. If there is not enough liquid in the intermediate chamber 20 to fill the tank 4, before the intermediate chamber 20 is empty, the valve V1 is opened and the valve V3 is closed. Refueling is then performed from the storage tank 2 directly. The liquid filling the tank 4 being mainly from the intermediate chamber 20, it can be provided to change the temperature and / or the pressure within this intermediate chamber 20 before starting the refueling. A measurement of the temperature and of the pressure in the intermediate chamber 20 is then carried out before the beginning of the refueling. If necessary, these parameters (temperature and pressure) can be adapted, in particular using the vaporizer 28 and / or the system. Cooling 30. It then acts on valves V6 and V8 and / or V9 to increase the pressure and / or temperature in the enclosure, the cooling system for its part to reduce the temperature and / or pressure. Once the transfer has been made, the first line 10 is filled with liquid from the storage tank 2 to the cryogenic equipment outlet while the second degassing line 12 contains a mixture of liquid and gas. The invention also proposes to limit as much as possible the vaporization of the liquid in the system after a liquid delivery operation. It then proposes to purge the system by pushing a maximum of liquid to the storage tank 2 before it vaporizes. To perform the purge, it is proposed, once the tank 4 filled as desired, to operate the vaporizer 28. The valve V6 is open, valves V7 and V9 closed. The valves V1 and V3 are open to allow the liquid remaining in the system to be pushed back to the storage tank 2. In order also to discharge the liquid located at the pump 6 and the equipment 8, it is then possible to close valve V3 and open valves V4 and V5. The configuration of the system with the low point 16 will then allow the pipes containing liquid to be purged by means of the vapors which will push the liquid towards the storage tank 2. In effect, the liquid contained in the first pipe 10 descends through gravity towards the low point 16. It should be noted here that the distal ends of the first pipe 10 and the second pipe 12 are closed. In the design of the first pipe 10, it will preferably be ensured that no liquid "trap" is left in such a way that all the liquid can descend advantageously towards the low point 16. Fatally, because of the inevitable thermal losses in all 5 system, liquid in the system will vaporize. Fluid will therefore go from the liquid phase to the gas phase. The gas phase fluid will accumulate from the highest zones in the system. With the system closed, as liquid vaporizes, the pressure will increase and the fluid in the liquid phase is pushed back through the valve V1 into the storage tank 2. The purge phase can be ends when there is no fluid in the liquid phase at the low point 16 and the gaseous phase thus reaches the low point 16. Once the purge of the system is completed, the valves V1 and V3 remain closed until the next liquid delivery. As an alternative embodiment (not shown), it is possible to provide for the pump 6 to be installed inside the intermediate enclosure 20. In fact, it is usual to place a cryogenic pump, such as the pump 6, in the inside a thermally insulated enclosure. In this embodiment, a cryogenic enclosure 20 can then be saved with respect to the embodiment illustrated in FIG. 2. It may be noted that in this embodiment (pump in the intermediate enclosure), the additional cost of a installation according to the present invention is very limited compared to a similar installation of the prior art. Another alternative embodiment provides that the valve V3 is a distributor with associated control means that allows for dynamic mixing between the liquid from the storage tank 2 and the liquid of the intermediate chamber 20. Certain variant allows in particular to achieve a "mixing valve" and therefore to adjust the temperature of the liquid sent to the tank 4 to fill. Another variant within the reach of the skilled person is to replace the storage tank which is shown very schematically in Figure 2 by a thermosiphon tank. In this case, the pipes comprising the valves V2 and V4 are for example connected to the upper part of the intermediate chamber 20 and make it possible to ensure the degassing produced in the embodiment of FIG. 2 by the valve V7. As a purely illustrative and nonlimiting numerical example, numerical values are indicated below with reference to FIG. 2. The pump 6 is placed in an enclosure to keep it cool, especially when it is not working. Only rapid cooling is necessary before each use. The cryogenic liquid used is liquefied natural gas.
    [0015] In the storage tank, the pressure is for example 3 bar and the temperature of -146 ° C. In a first step, 130 liters of liquefied natural gas are transferred to the intermediate chamber 20. This liquid comes to cool the intermediate chamber and the 130 I are then found in said chamber at 6 bar and -134 ° C. A second step is then provided to cool the pump. 130 l of liquefied natural gas are still in the intermediate chamber but at a pressure of 10.5 bar and a temperature of -123 ° C. The temperature increases here because of the heat provided by the cooling of the pump. A third step provides for the cooling of the equipment 8. It is then added liquefied natural gas in the intermediate chamber 20 which contains for example 2601 liquefied natural gas. The pressure increases further to reach 14 bar and the temperature rises to -116 ° C.
    [0016] The next step is then to empty the intermediate chamber 20 with the pump 6. This operation is stopped shortly before completely emptying the intermediate chamber. The last step is a system purge step in which as much liquid as possible is returned to the storage tank again. The present invention thus makes it possible to avoid to a large extent that the heat coming from the cooling of the various components (pump and / or various equipment) is introduced - especially in the form of vapors - into the storage tank. In this way, the cryogenic liquid in this tank remains cold longer. The heat recovered during cooling operations is recovered to be sent to the container to be filled where it is often necessary to saturate the liquid. In addition, the container to be filled on the one hand, of reduced size and, secondly, to be emptied rather quickly (a few days maximum in general), the problems of heat input are less critical. The invention as described also allows to replace in a cryogenic fluid delivery system, after a liquid delivery operation from a storage tank to a container, the residual liquid by gas. In this way, the introduction of gas into the storage tank is limited, the residual fluid being reintroduced in liquid form into the storage tank. In this way, the vaporisation of cryogenic liquid is limited.
    [0017] The heat inputs into the system are also limited in this way and the liquid in the storage tank remains cold enough to ensure good storage conditions over a longer period. The system and / or the method according to the present invention also makes it possible, in particular in the case where the cryogenic liquid is liquefied natural gas, to limit the losses of natural gas by limiting the pressure increase in the storage tank and of this makes the number of trips of the safety valve associated with this tank. Of course, the present invention is not limited to the embodiment of the installation illustrated in the drawing, the variants mentioned in the foregoing description and the method described above. It also relates to all the variants within the scope of those skilled in the art within the scope of the claims below.
