Definitions
- the present invention relates to the field of cryogenic liquid filling processes, such as liquid nitrogen, a downstream reservoir, from an upstream storage.
- Such filling operations can be found, for example, for filling tanks in trucks used for transporting and dispensing heat-sensitive products, such as pharmaceuticals and food products.
- one of the techniques used in this type of truck uses one (or more) heat exchanger (s) located (s) inside the enclosure, in which is circulated a cryogenic fluid the enclosure is also provided with an air circulation system (fans) putting this air in contact with the cold walls of the exchanger, thereby cooling the air inside the cold room of the truck, the cryogenic fluid supplying the exchanger (s) comes from a cryogenic tank traditionally located under the truck, which must therefore be filled regularly as touring.
- cryogenic fluid for example liquid nitrogen
- the tank is filled downstream, such as the tank of a truck, the upstream storage being under pressure.
- cryogenic fluid in the liquid phase at the bottom of the tank and in the gaseous phase at the top of the tank, this storage being adapted to firstly feed the reservoir to be filled downstream with liquid which is withdrawn at bottom of the storage, and secondly to be supplied from the outside in fluid.
- low storage pressure that is to say, the maximum pressure reached at the top of the tank is generally less than about 4 bar absolute, typically 1.5 bar relative pressure at the top of the storage, but there are also in this technical field storage up to 17 bar for a downstream use pressure of, for example, 4.5 bar.
- cryogenic pump In order to proceed with the rapid transfer of the fluid between this upstream storage and such a downstream reservoir to be filled, it is possible to envisage using a cryogenic pump to increase the upstream pressure during the transfer to the cryogenic reservoir situated downstream.
- cryogenic pumps may present disadvantages in terms of cost, maintenance obligations, and specific operational constraints such as cold setting before use.
- a cryogenic pump indeed comprises rotating parts that require specific maintenance.
- Another solution has been proposed which consists in using an intermediate transfer capacity which will be pressurized before the final transfer to the downstream reservoir. This solution then involves the use of an additional reservoir, resulting in a congestion constraint and a mode of operation that will depend greatly on the downstream process (pressurization before use and filling management when empty). .).
- Another solution has been proposed which consists in maintaining the cryogenic storage upstream at the operating pressure during the transfer, but it is known that, because of the behavioral characteristics of the cryogenic fluids, under these conditions the fluid will tend to move to the equilibrium temperature at the storage pressure, which will give rise to the creation of diphasic during the transfer therefore to a reduction of the flow rate related to the presence of the gas in the flow.
- the filling station consists of a simple manual valve.
- a hose for the transfer of liquid nitrogen connects the filling station (i.e. the manual valve) and the tank.
- the gas created during the injection is discharged from the tank to the outside in an uncontrolled manner.
- the operator decides to end the filling when, visually, he detects liquid particles in the gases discharged from the tank. After interrupting the filling, the hose is purged by the operator.
- the gas outlet line of the tank is opened or closed by means of a manual valve on the tank.
- This valve allows complete opening / closing.
- the manual valve is opened, the gas is evacuated and the tank is at atmospheric pressure.
- a filling station through which passes a first path connecting the storage tank to fill and allowing the transfer of cryogenic liquid storage tank, and a second path connecting a gas outlet of the tank at the station. filling and allowing to bring the gases to be evacuated from the tank to the filling station where they can be discharged to the outside;
- the station comprises means for detecting the presence of the cryogenic ion in the gas brought back to the station, the detection information being used to allow the filling to stop automatically when the tank is considered to be full;
- the second channel connecting a gas outlet of the tank to the filling station, is provided with an overflow device, a pressure regulator set to an upstream pressure set point value which makes it possible to reach a minimum but above all fixed pressure inside the tank; , necessary for further use of the reservoir considered without the need for implementation of a pressure rise system.
- the discharge device sets the gas head pressure of the reservoir which is filled to the utilization value, for example 2.5 bar, so the differential pressure between the upstream storage and the reservoir is imitated since the pressure in the reservoir is fixed.
- the present invention thus wishes to propose a new technical solution for filling cryogenic liquid (such as liquid nitrogen) of a downstream reservoir, from an upstream storage, to solve the technical disadvantages listed above.
- cryogenic liquid such as liquid nitrogen
- This solenoid valve on the gas return is "normally closed” (NF) it allows to depressurize as much as necessary the tank and thus to obtain a desired Delta P pressure difference, including maximum, where a maximum flow.
- the pressure in the upstream storage can be lowered if necessary to usual values, for example 2.9 bar.
- the solenoid valve makes it possible to adjust the pressure of the reservoir to be filled to a desired pressure, for each reservoir that is present at the filling, this final pressure is not fixed (which was created by the overflow device) it may be different from one tank to another that must be filled, depending on the application of the cryogen stored in this tank in particular.
- the final pressure of the filled tank can typically vary from 1 to 4.5 bar, but most often it ranges from 1 to 2.5 bar.
- the Delta P between upstream and downstream is an important parameter, especially to promote a high flow, so we look for a high Delta P, with a downstream pressure (reservoir) very low or close to 0 bar relative.
- the present invention thus relates to a process for filling with a cryogenic liquid a reservoir, from an upstream storage, filling during which a portion of the cryogenic liquid is converted into a gas phase in the reservoir, and where it is carried out, during the filling, at the evacuation of at least a portion of the gas thus formed, where there is a filling station through which passes a first path connecting the storage tank and allowing the transfer of cryogenic liquid storage tank, and a second channel connecting a gas outlet of the tank to the filling station and to bring the gas to be discharged from the tank to the filling station where they can be discharged to the outside, the station comprising means detecting the presence of cryogenic liquid in the gas brought back to the station, the detection information being transmitted to an acquisition unit and of data processing internal or not to the station, able to allow the automatic stop of the filling when the tank is considered as full, and characterized in that the second gas return line to the station is devoid of a discharge but is provided with a solenoid valve or several solenoid valves
- the invention also relates to a cryogenic liquid filling plant of a tank, from an upstream storage, filling during which a portion of the cryogenic liquid is converted into a gas phase in the tank, and where it is carried out, during filling, at the evacuation of at least a portion of the gas thus formed, where:
- the installation includes a filling station
- the installation comprises a first fluid path passing through the filling station, connecting the storage tank and allowing the transfer of cryogenic liquid storage tank;
- the installation comprises a second fluidic channel connecting a gas outlet of the tank to the filling station and making it possible to return the gases to be discharged to the filling station;
- the station comprises means for detecting the presence of cryogenic liquid in the gas brought back to the station,
- the installation comprises a data acquisition and processing unit able to receive the detection information from said detection means, and according to the information received, to order the automatic shutdown of the filling when the received information indicates that the tank is full, and characterized in that the second gas return line to the station is devoid of discharge but is provided with a solenoid valve or several solenoid valves arranged in parallel, normally closed (s).
- the invention may furthermore adopt the one or more of the following technical characteristics:
- said detection means are constituted by a temperature probe located on said second channel, indicating an abnormally high temperature drop in the gas brought back to the station.
- a first double-fitting where a flexible portion of the first channel connecting the storage tank to the reservoir, and which is derived from a flexible portion of the second channel connecting the gas outlet of the tank to the station;
- the connection of the two double - connections ensuring the continuity of fluids on the first channel on the one hand connecting the storage to the tank, and on the second channel on the other hand, bringing the gas outlet of the tank to the station.
- said second double - connection is in fluid connection with the upper part of the tank.
- a purge line is provided, equipped with a solenoid valve, a purge line which is connected in its upstream part to said first channel connecting the storage to the tank, and to which is advantageously connected the second channel which brings back the gases to evacuate to the filling station, allowing thus to evacuate via the purge line to the outside gases evacuated from the reservoir and brought back to the station.
- the hose is purged by the opening of a solenoid valve located on a purge line which is connected in its upstream portion on said first channel connecting the storage tank.
- a sensor for detecting the correct positioning of said first double-connection on a hang-up element present on the filling station and the hook-up of said first double-connection on this element automatically starts bleeding the flexible portion of the first track connecting the storage to the first double - connection.
- the tank is present on a truck used for the transport and distribution of temperature-sensitive products, such as pharmaceuticals and food products.
- FIG. 1 shows schematically a known filling system of the tank of a refrigerated transport truck to visualize the presence of the filling station between storage and tank;
- FIG. 2 is a detailed view of the content of the filling station according to one of the embodiments of the prior art (presence of an overflow on the gas return).
- FIG. 3 is a detailed view of the contents of the filling station according to one embodiment of the present invention implementing a single solenoid valve on the gas return (gas return without a discharge).
- FIG. 4 is a detailed view of the content of the filling station according to another of the embodiments of the present invention implementing two solenoid valves in parallel on the gas return (gas return without discharge).
- FIG. 1 has two parts:
- connection of the two double-connections ensuring the continuity of fluids on the first channel on the one hand connecting the storage tank, and on the second channel on the other hand, bringing the gas outlet of the tank to the station, the second double - connection ("tank side") being in fluid connection with the upper part (“gas”) of the tank.
- FIG. 2 will examine in greater detail the content of a filling station according to the prior art which used a gas discharge overflow device.
- This FIG. 2 makes it possible to display the storage 1 of liquid nitrogen, as well as the contents of the filling station 5, as well as the lines passing through it or ending therein: the cryogenic liquid supply line
- a solenoid valve 20 and a discharge valve 21 On the second gas return pathway, the presence of a solenoid valve 20 and a discharge valve 21 is recognized. There is also a temperature sensor 23 (whose function is to detect the presence of liquid in the gas return). and thus to allow on the basis of this information the stop filling), as well as a pressure sensor 22.
- FIG. 2 also shows the means for evacuation towards the outside of the gases discharged from the reservoir and brought back to the station: a purge line 30 is present, as connected in its upstream part to the cryogenic nitrogen path, purge on which is connected the gas return path, this purge line is provided with a purge solenoid valve 31 and a silencer 33.
- valves 1 1, 24, and 32 Note also in Figure 2 the presence of manual valves "by-pass" on each of the lines, valves 1 1, 24, and 32, designed to allow emergency operation for a limited time in case of malfunction of the station .
- the temperature sensor 23 installed on the gas return line in the filling station makes it possible to detect an abnormally large fall in the temperature of this gas return. presence of liquid nitrogen in the gas return, indicating complete filling of the tank.
- This detection information is sent to the data acquisition and processing unit present in the station, which unit then orders the filling to stop (closure of the valve 10, closing of the valve 20 to avoid a loss of pressure in the tank and its inadvertent degassing).
- valve 31 on the purge line 30 must be open and therefore controlled.
- two events can be used to order the opening of this valve 31:
- the station can, for example, detect the presence of the "storage" double-connection which has been brought back after uncoupling on its hooking support on the station;
- the unit can also count the end of a time delay (for example, 2 minutes) after it (the unit) has ordered the filling to stop.
- a time delay for example, 2 minutes
- the solenoid valve 20 normally closed, being controlled according to the pressure required in the tank to evacuate gas if necessary.
- FIG. 3 which illustrates an embodiment of the invention, in which the gas return does not include a discharge device, the filling and the pressure carried out in the tank being controlled only by the sole presence of the solenoid valve. 20 (it will be seen in the context of Figure 4 that it is possible to implement preferably two parallel solenoid valves 20 and 40 on this gas return).
- filling is normally carried out until the probe 22 detects a pressure in the gas sky of the reservoir too much. high, in which case the automaton orders the opening of the solenoid valve 20 to reduce this pressure below the fixed setpoint, once this pressure is brought back below the set point the controller orders the closing of the solenoid valve 20.
- the automaton orders the closure of the solenoid valve 10 (thus stopping the arrival of cryogen).
- FIG. 4 The mode of FIG. 4 is identical almost in all respects to that of FIG. 3, except that for this mode, the gas return is provided not with only one but with two solenoid valves in parallel: XV03 / 20 and XV05 / 40.
