[0001] This invention relates to a cryogenic tank and a method of supplying such a tank.

[0002] More specifically, the present invention relates to a mobile cryogenic tank for transporting cryogenic fluids, particularly liquefied hydrogen or liquefied helium, the mobile cryogenic tank comprising an inner shell for containing the cryogenic fluid, an outer shell positioned around the inner shell, a space defined between the two shells, the space containing insulation, the first shell having a cylindrical overall shape extending along a central longitudinal axis, the central longitudinal axis being horizontally oriented when the tank (1) is in transport and use configuration, the tank including a set of temperature sensors for measuring the temperature of the fluid in the inner shell.

[0003] The present invention relates in particular to semi-trailers or ISO containers for transporting cryogenic fluids, wherein the semi-trailers or ISO containers transport liquefied gases (where the upper part is a fairly large gas phase that can occupy, for example, from 10% to more than 90% of the inner shell volume).

[0004] The transported fluid may be, for example, helium, hydrogen, natural gas, or any other gas or mixture.

[0005] This mobile tank is designed to supply liquid stations with a wide variety of characteristics (e.g., to fill stationary storage tanks).

[0006] It is difficult to know the level and thermodynamic conditions of the fluid (liquid) being transported. However, knowing this is crucial for allowing efficient delivery to multiple stations.

[0007] The purpose of this invention is to overcome all or some of the shortcomings of the prior art described above.

[0008] Therefore, the main feature of the can according to the invention, conforming to the general definition given even in the above preamble, is that the set of temperature sensors is located on the outer surface of the inner shell and measures the temperature of the shell, the set of temperature sensors including a lower sensor positioned at the lower end of the inner shell below the central longitudinal axis, the set of temperature sensors further including a plurality of intermediate sensors distributed on two lateral faces of the inner shell on each side of the central longitudinal axis, the plurality of intermediate sensors being vertically distributed between the lower end of the inner shell below the central longitudinal axis and the upper end of the inner shell above the central longitudinal axis.

[0009] Furthermore, embodiments of the present invention may have one or more of the following features:

[0010] - This set of temperature sensors is located in the central part between the two longitudinal ends of the tank.

[0011] - The multiple intermediate sensors include two sets of sensors, each set having three to ten sensors. These two sets of sensors are located on two opposite lateral surfaces on each side of the central longitudinal axis of the inner shell, and the sensors are vertically spaced apart from each other between the lower and upper ends of the inner shell.

[0012] - Each of these two sets of intermediate sensors includes four, five, six, seven, or eight sensors.

[0013] - This set of temperature sensors includes an upper sensor positioned at the upper end of the inner housing above the central longitudinal axis.

[0014] This temperature sensor group comprises multiple sensor clusters located at two different longitudinal positions along the longitudinal direction. Each of these temperature sensor clusters includes multiple intermediate sensors distributed on two lateral faces of the inner shell on each side of the central longitudinal axis, and vertically distributed between the lower end of the shell below the central longitudinal axis and the upper end of the shell above the central longitudinal axis.

[0015] The tank includes an electronic data storage and processing component with a microprocessor and / or computer, the electronic component being connected to the set of temperature sensors and configured to receive temperature values ​​measured by the sensors and determine at least one of the following: the temperature of the fluid in the tank, the liquid level in the tank, and the liquid volume in the tank.

[0016] - The tank includes a pressure sensor for measuring the pressure inside the shell.

[0017] - The tank includes a set of pipes equipped with multiple valves, which connect to the inner shell and open to the outside of the tank for filling and emptying the inner shell.

[0018] - The tank includes at least one intermediate sensor located at a vertical position on the inner shell, which corresponds to the maximum liquid level to which liquid is being added to the tank, and in particular to the liquid level at which adding liquid to the tank stops, for example, between 90 and 98%, and in particular 94%, of the water volume of the inner shell.

[0019] The present invention also relates to a method for supplying cryogenic fluid to a plurality of cryogenic fluid storage and use stations, the supply to said stations being carried out via at least one mobile cryogenic tank according to any of the features described above or below, wherein each of these fluid storage and use stations includes a liquefied gas fluid storage tank configured to store the cryogenic fluid under defined thermodynamic pressure and temperature conditions, the method comprising: measuring the temperature and pressure of the cryogenic fluid in the mobile cryogenic tank; reading the defined thermodynamic temperature and pressure conditions in each of the liquefied gas fluid storage tanks of these stations; and delivering the cryogenic fluid to the stations in a corresponding fluid volume depending on the cryogenic fluid temperature and pressure measured in the mobile cryogenic tank and the defined thermodynamic temperature and pressure conditions in each of the liquefied gas fluid storage tanks of these stations.

[0020] Based on other possible distinguishing features:

[0021] The method includes sequentially delivering cryogenic fluid to a first station and then to a second station. Before delivering the cryogenic fluid to the first station, the method includes the following steps: increasing the pressure in the mobile cryogenic tank by deterministically adding energy, i.e., by extracting some fluid, heating it, and then re-injecting it into the mobile cryogenic tank; the method includes the following steps: after delivering the cryogenic fluid, calculating future pressure and temperature equilibrium conditions in the mobile cryogenic tank based on the aforementioned amount of added energy and the temperature and pressure of the cryogenic fluid in the mobile cryogenic tank; the method includes: interrupting the delivery of cryogenic fluid to the first station if the calculated future pressure and temperature equilibrium conditions in the mobile cryogenic tank are higher than the determined thermodynamic temperature and pressure conditions of the storage tank at the second station.

[0022] The delivery of cryogenic fluid to the station is performed in chronological order, which is determined based on the temperature and pressure of the cryogenic fluid in the mobile cryogenic tank and the determined thermodynamic temperature and pressure conditions of each liquefied gas fluid storage tank at the station.

[0023] The present invention may also relate to any alternative apparatus or method that includes any combination of the above or following features within the scope of the claims.

[0024] Other features and advantages will become clear from the following description given with reference to the accompanying drawings:

[0025] [ Figure 1 A schematic partial side view of a first example of a can according to the invention is shown.

[0026] [ Figure 2 A schematic partial cross-sectional view is shown, illustrating another example of a can according to the invention.

[0027] [ Figure 3 A schematic partial side view of a second example of a can according to the invention is shown.

[0028] [ Figure 4 The diagram shows a partial view illustrating an example of supplying cryogenic fluid to a station via a mobile tank.

[0029] The mobile cryogenic tank 1 includes an inner shell 2 designed to contain cryogenic fluids. The inner shell 2 (e.g., having an overall cylindrical shape) defines the fluid storage volume. For example, the inner shell 2 includes a cylindrical portion with a circular cross-section (made of a shell ring of stainless steel or any other suitable material compatible with the stored fluid), with a bent end welded to the end of the cylindrical portion.

[0030] The tank 1 also includes an outer shell 3, which is positioned around the inner shell 2 and defines a space between the two shells 2 and 3. The outer shell 3 may be made of, for example, carbon steel, stainless steel, or aluminum, and may be reinforced, if appropriate, with rings welded to the inner and / or outer sides. The retention system for holding the inner shell 2 in the outer shell 3 may involve a connector at the longitudinal end and / or a set of retention arms. For example, the inner shell 2 is held and supported in the outer shell 3 by a cylindrical member or strap made of stainless steel, fixed at the rear and movable at the front (front and rear refer to the longitudinal ends) to allow the inner shell 2 to contract freely during cooling.

[0031] Typically, this space contains insulation 4: vacuum and / or insulating materials such as multilayer insulation (MLI), or any other suitable insulator.

[0032] The inner wall can be filled with multiple layers of insulating material and can be placed under vacuum, then sealed with a check valve that seals the pump outlet. An auxiliary check valve can be provided to measure the vacuum and may allow further pumping. Preferably, a safety device is provided to prevent any accidental overpressure within the inter-wall space. A stainless steel outlet plate can be provided in the lower part of the rear end cover for the passage of the tubing connected to the inner shell 2.

[0033] The outer shell 3 can have a similar shape to the inner shell 2.

[0034] The first shell 2 has a cylindrical overall shape extending along a central longitudinal axis A, for example, the cylindrical portion (preferably a rotating cylinder) extends about a symmetrical central axis A. When the can 1 is in use configuration, this central longitudinal axis A is horizontal (or substantially horizontal, as it can be slightly tilted if needed). This means that the can 1 is oblong and of the "horizontal" type (as opposed to a fixed vertical can).

[0035] The outer casing 3 can be mounted on a chassis with independent supports. This chassis may include connectors (brackets) and can be connected to a running gear equipped with braking devices, wings, and skirts conforming to current relevant standards. Other possible supports may include retractable landing gear and semi-trailer fifth wheels fitted with standardized kingpins.

[0036] Tank 1 includes a set of temperature sensors for measuring the temperature of the fluid in the inner shell 2. These temperature sensors are located on the outer surface of the inner shell 2 and indirectly measure the temperature of the fluid by measuring the temperature of the outer surface of the shell 2.

[0037] Therefore, these temperature sensors are preferably installed between the inner shell (on the outer skin) and the separator 4.

[0038] This set of temperature sensors includes a lower sensor 5 located at the lower end of the inner shell 2, below the central longitudinal axis A. This lower sensor 5 is, for example, located on the bottom generatrix of the cylindrical wall. Therefore, this lower sensor 5 measures the temperature at the lowest point of the inner shell 2 (which theoretically is always in the liquid phase).

[0039] This temperature sensor set further includes multiple intermediate sensors 6, which are distributed on two lateral surfaces of the inner shell 2 on each side of the central longitudinal axis A. The multiple intermediate sensors 6 are vertically distributed between the lower end of the shell located below the central longitudinal axis A and the upper end of the inner shell 2 located above the central longitudinal axis A.

[0040] Furthermore, this set of temperature sensors preferably includes at least an upper sensor 7 positioned at the upper end of the inner shell 2 above the central longitudinal axis A. The upper sensor 7 is located, for example, on the top generatrix of the cylindrical wall, at the highest point of the inner shell 2.

[0041] Preferably, the tank 1 includes at least one intermediate sensor 6 located at a vertical position on the inner shell 2, corresponding to the maximum liquid level to which liquid is being added to the tank 1. For example, the sensor may be located at a defined height corresponding to the liquid level at which adding liquid to the tank 1 stops, such as 90% to 98%, particularly 94%, of the water volume of the inner shell 2. This temperature sensor can reliably detect when the liquid has reached its filling limit via temperature measurement. This can be used to interrupt adding liquid to the tank. If appropriate, this or these sensors can replace the aforementioned upper sensors 7(s).

[0042] The temperature sensors 5, 6, and 7 are preferably located in the central portion between the two longitudinal ends of the tank 1, that is, for example, in the middle between the front end and the rear end of the tank 1 in the longitudinal direction of the tank 1.

[0043] For example in [ Figure 1As can be seen in the image, the plurality of intermediate sensors 6 preferably include sensors located on two opposite lateral surfaces on each side of the central longitudinal axis A of the inner shell 2, and these intermediate sensors 6 are vertically spaced apart from each other between the lower and upper ends of the inner shell 2. For example, two groups of three to ten intermediate sensors 6 are each located on two opposite lateral surfaces of the inner shell 2. Figure 1 In a non-limiting example, there are five intermediate sensors 6 between the lower sensor 5 and the upper sensor 7 on each lateral surface. Of course, they can be fewer (two, three, four) or more (six, seven, eight, nine, ten, etc.).

[0044] The intermediate sensors 6 located on each side of the longitudinal axis A are, for example, symmetrically positioned, i.e., positioned at the same height. Of course, it is conceivable that the two sets of sensors 6 are arranged vertically offset.

[0045] For the inner shell 2 with a diameter between 500 and 2800 mm, especially 2400 mm, the number of intermediate sensors 6 is preferably at least five or six, and they are spaced apart from each other on the circumference by about 200 to 600 mm, especially about 500 mm. The sensors can be vertically or evenly spaced around the circumference.

[0046] For more accurate measurements, the number of sensors 6 can be increased and their spacing can be shortened to actually cover the entire height of the inner shell 2.

[0047] For example in [ Figure 1 As can be seen in the image, preferably, for example, the tank 1 includes an electronic data storage and processing component 8 having a microprocessor and / or a computer. This electronic component 8 is connected (via a wired or wireless link) to the set of temperature sensors 5, 6, 7 and is configured to receive temperature values ​​measured by the sensors.

[0048] This onboard data acquisition can use a PLC (Programmable Logic Controller) and can be downloaded when the tank returns to the central station, and / or transmitted wirelessly, for example, using GSM communication.

[0049] Installed on the tank or remotely (see [ Figure 3 This electronic component 8 (illustrating both scenarios) is configured to determine at least one of the following: the temperature of the fluid in the tank, the liquid level in tank 1, and the liquid volume in tank 1. In particular, these multiple sensors enable more precise determination of the liquid level via temperature measurement and temperature stratification in the inner shell 2.

[0050] Preferably, the electrical components (the connecting cable between the sensor and electronic component 8) are positioned within the wall space of the tank 1 and extend forward. Therefore, the outlets for the circuitry targeting component 8 located outside the tank are located at the front of the tank, preferably at the end opposite to the fluid circuit described in detail below. These electrical lead channels at the front of the tank allow them to be positioned away from potentially explosive atmospheres (flammable gas vapors).

[0051] In practice, tank 1 typically includes a set of pipes 10, 11 equipped with valves(s) 12, 13, which connect to the inner shell 2 and open to the outside of tank 1 for filling and drawing from the inner shell 2. Furthermore, tank 1 preferably includes a pressurization device to allow liquid to be drawn, heated, and re-injected into the inner shell 2 to increase the pressure within the shell 2. Such a pressurization heater may include a tube bundle (with or without fins) designed to vaporize the liquid supplied to it by gravity. The resulting gas returns to the gas phase of the inner shell 2, thereby providing the pressurization required for direct liquid delivery or starting a delivery pump. This fluid loop is preferably located at the other end of tank 1, i.e., the rear end.

[0052] A control cabinet can be installed at the rear of the tank to house and organize the safety, control, and operating accessories required for the use of tank 1, especially faucets, valves, pressure gauges, level gauges, and flow meters.

[0053] Preferably, these accessories are checked for leaks at low temperatures.

[0054] A pressure sensor 9 can be provided to measure the pressure in the inner shell 2, and its measurement value can be provided to the electronic component 8 if necessary.

[0055] [ Figure 3 Variants of the embodiments in ] and [ Figure 2 The difference in the embodiment variant is that this group of temperature sensors comprises multiple sensors 5, 6, and 7 grouped at different longitudinal positions along the longitudinal direction A. Figure 3 In the example of ], there are three groups of sensors arranged longitudinally (instead of according to [ Figure 1 (One sensor group). The three sensor groups are distributed as follows: one group in the middle, and two groups near the longitudinal ends of the inner shell 2. Of course, configurations with two, four or more sensor groups can be envisioned.

[0056] This type of tank allows for better knowledge of the distribution and temperature of the gas and liquid phases. This temperature information, in turn, enables adjustments to the flow and filling of stations supplying cryogenic fluids. This allows for the limitation of the amount of evaporated gas and the emission of gas into the atmosphere.

[0057] This allows for improved vapor-phase recovery achieved by the increased pressure when tank 1 returns to the filling center (liquid source, such as the liquefier). Understanding and controlling the temperature of the depressurized gas in the liquefier has a significant impact on the re-condensation process. This allows for optimization of the vapor-phase recirculation process.

[0058] The temperature measurement results allow for a more accurate determination of the liquid level within the inner shell 2, especially when unloading or parking tank 1 (particularly in the case of stratification within the inner shell 2).

[0059] This allows for better monitoring of the contents and improves the reliability of logistics by allowing the inspection of calculated values ​​of the delivered fluid volume.

[0060] In multi-fluid delivery streams, the measured liquid temperature has a significant impact on pressure management at the destination station. Specifically, stations 11, 12, and 13 may have relatively hotter or relatively colder fluid requirements (e.g., liquid hydrogen at -240°C, 3 bar pressure or -240°C, 9 bar pressure). Temperature measurement in mobile tank 1 allows for corresponding adjustments to the delivery sequence (e.g., from coldest to hottest). Where a station requires a relatively warmer fluid, the pressure in tank 1 can be regulated using the relatively colder fluid if needed. This allows for improved pumping efficiency at the destination station. It also improves the reliability of the stream (e.g., no ventilation is required because there is no gas generation).

[0061] These temperature measurements allow for the expectation of a pressure drop in the inner shell 2 after the driver applies the braking procedure (aimed at reducing pressure by mixing the two phases) to avoid ventilating the trailer at the delivery site.

[0062] Furthermore, in the case of continuous delivery, temperature (and, where appropriate, pressure) measurements allow for the calculation in advance of the thermodynamic equilibrium conditions in the inner shell 2 after delivery, and whether these conditions are compatible with the thermodynamic requirements of the next delivery.

[0063] Specifically, when the pressure in the mobile cryogenic tank 1 is increased by deliberately adding energy (by extracting some cryogenic fluid, heating it, and then re-injecting it into the tank) before delivering the cryogenic fluid to the first station 11, the future pressure and temperature equilibrium conditions in the inner shell 2 at the end of the cryogenic fluid delivery can be calculated based on the initial temperature and pressure conditions, and possibly the conditions in the inner shell 2 during the heating process, as well as the delivery amount. If these conditions are incompatible with the subsequent delivery to another station 12, the first delivery can be interrupted, for example, prematurely.

[0064] These calculations can be performed using equations or models based on the first law of thermodynamics, applied to the enclosed volume formed by the can.
