Description

Installation et procédé de stockage et de distribution de liquide cryogénique Installation and method for storing and distributing cryogenic liquid
1/ invention concerne une installation et un procédé de stockage et de distribution de liquide cryogénique. 1 / invention relates to an installation and a method for storing and distributing cryogenic liquid.
1/ invention concerne plus particulièrement une installation de stockage et de distribution de liquide cryogénique, notamment d'hydrogène liquéfié, comprenant un réservoir cryogénique isolé thermiquement pour le stockage d'un gaz liquéfié en équilibre avec une phase gazeuse, un dispositif de réfrigération du fluide contenu dans le réservoir, le dispositif de réfrigération comprenant un circuit de fluide réfrigérant muni d'un échangeur de chaleur situé dans la partie inférieure du réservoir et un réfrigérateur de refroidissement du fluide réfrigérant. 1 / invention relates more particularly to an installation for the storage and distribution of cryogenic liquid, in particular of liquefied hydrogen, comprising a thermally insulated cryogenic tank for the storage of a liquefied gas in equilibrium with a gaseous phase, a device for refrigeration of the fluid contained in the reservoir, the refrigeration device comprising a refrigerant circuit provided with a heat exchanger located in the lower part of the reservoir and a refrigerator for cooling the refrigerant fluid.
L'invention concerne notamment un dispositif de stockage de liquide cryogénique (gaz liquéfié) qui est sous refroidi et maintenu sous pression pour sa distribution. The invention relates in particular to a device for storing cryogenic liquid (liquefied gas) which is subcooled and maintained under pressure for its distribution.
Ces conditions peuvent être intéressantes pour densifier un liquide tout en restant au-dessus de la pression atmosphérique ou à une pression suffisante pour effectuer le transfert du liquide vers un autre réservoir par différence de pression. These conditions can be advantageous for densifying a liquid while remaining above atmospheric pressure or at a pressure sufficient to effect the transfer of the liquid to another reservoir by pressure difference.
Il est généralement malaisé de maintenir la pression du fluide dans un tel réservoir alors que la température du liquide est sous la température d'équilibre avec la vapeur à cette pression (liquide sous-refroidi). It is generally difficult to maintain the pressure of the fluid in such a reservoir while the temperature of the liquid is below the equilibrium temperature with the vapor at this pressure (sub-cooled liquid).
Une méthode connue pour maintenir la pression dans un tel réservoir est d'injecter du gaz chaud dans la partie gazeuse (supérieure) du réservoir (quand la pression baisse). Ce gaz est souvent du liquide prélevé dans le fond du réservoir et réchauffé (échangeur atmosphérique) avant d'être injecter dans la partie haute de celui-ci. L'inconvénient de cette méthode est qu'elle génère un apport de chaleur supplémentaire qui rentre dans le stockage et qu'il faudra ensuite compenser soit par un liquéfacteur qui alimente le stockage avec du liquide, soit via un rejet vers l'extérieur sous forme de « boil-off » (gaz de vaporisation) lorsque la pression va à nouveau augmenter. A known method of maintaining the pressure in such a reservoir is to inject hot gas into the gaseous (upper) part of the reservoir (when the pressure drops). This gas is often liquid taken from the bottom of the tank and reheated (atmospheric exchanger) before being injected into the upper part of the latter. The downside of this method is that it generates an additional heat input which enters the storage and which will then have to be compensated either by a liquefier which supplies the storage with liquid, or via a discharge to the outside in the form of a "boil-off" (vaporization gas) when the pressure will rise again.
Une autre méthode connue afin de limiter la pression (quand celle-ci augmente) dans un tel réservoir est d'ajouter un échangeur de chaleur dans la partie gazeuse et/ou liquide de ce réservoir. Cet échangeur, alimenté en fluide de refroidissement, permet de refroidir et condenser les vapeurs avec une source de froid extérieure (réfrigérateur tel qu'une tête froide d'un cryo-refroidissement Gifford-Mac Mahon, un cycle frigorifique, ...). Cf. EP2772677A. Another known method for limiting the pressure (when it increases) in such a tank is to add a heat exchanger in the gaseous and / or liquid part of this tank. This exchanger, supplied with cooling fluid, allows the vapors to be cooled and condensed with an external cold source (refrigerator such as a cold head of a Gifford-Mac Mahon cryo-cooling, a refrigeration cycle, etc.). See EP2772677A.
Les solutions connues ne permettent pas de maximiser les conditions et la quantité de gaz liquéfié sous refroidi. The known solutions do not make it possible to maximize the conditions and the quantity of liquefied gas under cooled.

D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence à la figure unique qui représente une vue schématique et partielle illustrant la structure et le fonctionnement d'un exemple de réalisation d'une installation selon l'invention. Other features and advantages will become apparent on reading the description below, made with reference to the single figure which represents a schematic and partial view illustrating the structure and the operation of an exemplary embodiment of an installation according to invention.
L'installation 1 de stockage et de distribution de liquide cryogénique, notamment de d'hydrogène liquéfié, comprenant un réservoir 2 cryogénique isolé thermiquement exemple pour le stockage d'un gaz liquéfié en équilibre avec une phase gazeuse. Par exemple, le réservoir est un réservoir à double enveloppe avec un vide entre les deux enveloppes. Classiquement le réservoir 2 est muni au moins d'une conduite 8 de soutirage de liquide. The installation 1 for storing and distributing cryogenic liquid, in particular liquefied hydrogen, comprising a thermally insulated cryogenic tank 2, for example, for the storage of a liquefied gas in equilibrium with a gaseous phase. For example, the tank is a jacketed tank with a vacuum between the two jackets. Conventionally, the reservoir 2 is provided with at least one pipe 8 for withdrawing liquid.
L'installation 1 comprend classiquement un dispositif de réfrigération du fluide contenu dans le réservoir 2. Le dispositif de réfrigération comprend un circuit 3 de fluide réfrigérant (notamment une boucle) muni d'un échangeur de chaleur 4 logé dans la partie inférieure du réservoir 2. Le dispositif de réfrigération comprend en outre un réfrigérateur 4 (de préférence extérieur au réservoir 4) assurant le refroidissement du fluide réfrigérant qui est mis en circulation dans le circuit 3 et notamment dans l'échangeur 4 de chaleur (par exemple via une pompe oi équivalent). The installation 1 conventionally comprises a device for refrigerating the fluid contained in the reservoir 2. The refrigeration device comprises a refrigerant fluid circuit 3 (in particular a loop) provided with a heat exchanger 4 housed in the lower part of the reservoir 2 The refrigeration device further comprises a refrigerator 4 (preferably outside the tank 4) ensuring the cooling of the refrigerant which is circulated in the circuit 3 and in particular in the heat exchanger 4 (for example via an equivalent oi pump).
Selon une particularité avantageuse, le dispositif de réfrigération comprend un mécanisme 9 permettant le déplacement et de positionnement vertical de l'échangeur 4 de chaleur dans le réservoir 2 parmi une pluralité de positions verticales déterminées. C'est-à-dire que l'échangeur 4 de chaleur est monté de façon mobile dans le réservoir 2. According to an advantageous feature, the refrigeration device comprises a mechanism 9 allowing the movement and vertical positioning of the heat exchanger 4 in the tank 2 among a plurality of determined vertical positions. That is to say, the heat exchanger 4 is movably mounted in the tank 2.
L'échangeur 4 de chaleur est disposé dans la partie basse (dans la phase liquide) du réservoir 2 et peut être positionné à une distance suffisante de l'interface liquide-vapeur afin de conserver une stratification du liquide entre cette surface et l'échangeur 4 de chaleur. The heat exchanger 4 is placed in the lower part (in the liquid phase) of the tank 2 and can be positioned at a sufficient distance from the liquid-vapor interface in order to maintain a stratification of the liquid between this surface and the exchanger. 4 heat.
Cette stratification permet de garder le liquide sous- refroidi entre l'échangeur 4 de chaleur et la partie basse du réservoir tout en conservant un équilibre liquide-vapeur à l'interface gaz-liquide et donc de conserver la pression dans le réservoir 2. This stratification makes it possible to keep the liquid sub-cooled between the heat exchanger 4 and the lower part of the tank while maintaining a liquid-vapor balance at the gas-liquid interface and therefore to maintain the pressure in the tank 2.
Un fluide réfrigérant plus froid que le fluide contenu dans le réservoir 2 peut être mis en circulation dans l'échangeur 4 de chaleur. De cette façon, il est possible de réduire la température du liquide stocké sous sa température d'équilibre. Dans le cas d'un stockage d'hydrogène, de l'hélium peut être utilisé comme fluide réfrigérant. A refrigerant that is colder than the fluid contained in the tank 2 can be circulated in the heat exchanger 4. In this way, it is possible to reduce the temperature of the stored liquid below its equilibrium temperature. In the case of hydrogen storage, helium can be used as a refrigerant fluid.
La quantité de liquide se trouvant sous le niveau de l'échangeur 4 de chaleur va se refroidir par convection naturelle. La partie de liquide se trouvant au-dessus de l'échangeur 4 de chaleur va se stratifier entre la température sous-refroidie et la température d'équilibre avec la phase vapeur à l'interface liquide/vapeur (cette température d'équilibre dépendant de la pression dans le réservoir 2). La position verticale de l'échangeur 4 de chaleur peut être commandée automatiquement en fonction du niveau de liquide dans le réservoir 2 pour conserver uniquement une distance minimale déterminée de stratification entre l'échangeur 4 de chaleur et la surface du liquide. Par exemple cette distance peut être comprise entre 15cm et plusieurs mètres et de préférence entre 20cm et un mètre. Ceci permet de maximiser le volume de liquide sous-refroidi (au niveau et en dessus de l'échangeur 4 de chaleur). The quantity of liquid located below the level of the heat exchanger 4 will be cooled by natural convection. The part of liquid located above the heat exchanger 4 will stratify between the sub-cooled temperature and the equilibrium temperature with the vapor phase at the liquid / vapor interface (this equilibrium temperature depending on the pressure in the tank 2). The vertical position of the heat exchanger 4 can be controlled automatically as a function of the liquid level in the tank 2 in order to maintain only a determined minimum distance of stratification between the heat exchanger 4 and the surface of the liquid. For example, this distance can be between 15cm and several meters and preferably between 20cm and one meter. This makes it possible to maximize the volume of sub-cooled liquid (at and above the heat exchanger 4).
Par exemple, un organe 6 de contrôle comprenant un ordinateur ou un microprocesseur peut piloter et commander la position verticale de l'échangeur 4 de chaleur. Cet organe 6 de contrôle peut éventuellement contrôler également la pression et/ou la température dans le réservoir et notamment le dispositif 5 de réfrigération. For example, a control member 6 comprising a computer or a microprocessor can control and control the vertical position of the heat exchanger 4. This control member 6 can optionally also control the pressure and / or the temperature in the tank and in particular the refrigeration device 5.
Pour permettre son déplacement vertical, l'échangeur 4 de chaleur 3 peut être relié au circuit 3 via des tuyauteries souples et/ou flexible afin de permettre son déplacement dans le liquide en fonction du niveau de liquide. To allow its vertical displacement, the heat exchanger 4 3 can be connected to the circuit 3 via flexible and / or flexible pipes in order to allow its displacement in the liquid as a function of the liquid level.
Le positionnement de l'échangeur 4 de chaleur peut être réalisé par exemple via un ou des flotteurs 7 reliés à l'échangeur 4 de chaleur. Dans le cas d'un réservoir 2 stockant de l'hydrogène, du fait de la densité de l'hydrogène liquide (environ 70 kg/m3), le flotteur 7 devra avoir une densité plus faible pour permettre sa fonction. L'hélium sous faible pression permet d'être inférieur à cette densité (entre 2 et 5 kg/m3) à cette température. Les tuyaux d'alimentation/distribution de l'échangeur 4 de chaleur peuvent également faire office de flotteur(s). Pour cela ces derniers peuvent avoir un diamètre et une masse optimisées dans ce but. The positioning of the heat exchanger 4 can be achieved for example via one or more floats 7 connected to the heat exchanger 4. In the case of a tank 2 storing hydrogen, due to the density of the liquid hydrogen (approximately 70 kg / m3), the float 7 must have a lower density to allow its function. Low pressure helium makes it possible to be less than this density (between 2 and 5 kg / m3) at this temperature. The supply / distribution pipes of the heat exchanger 4 can also act as float (s). For this, the latter can have a diameter and a mass optimized for this purpose.
Le fluide stocké dans le réservoir 2 peut le cas échéant être maintenu sous forme supercritique (c'est-à-dire dans un état thermodynamique au-delà des pression et températures critiques). Dans ce cas les désignations « liquide » et « gaz » sont moins pertinentes et peuvent être remplacées « fluide à grande densité » et « fluide à densité plus faible ». The fluid stored in the reservoir 2 can, if necessary, be maintained in supercritical form (that is to say in a thermodynamic state beyond critical pressures and temperatures). In this case the designations "liquid" and "gas" are less relevant and can be replaced "high density fluid" and "lower density fluid".
