Description
La présente invention concerne le domaine des équipements de vaporisation de liquides cryogéniques (CO2, azote, oxygène, argon…), elle s’intéresse tout particulièrement au cas du CO2, ceci afin de les transformer à l’état gazeux avant leur utilisation.The present invention relates to the field of equipment for the vaporization of cryogenic liquids (CO 2 , nitrogen, oxygen, argon, etc.), it is particularly interested in the case of CO 2 , in order to transform them into a gaseous state before their use. .
On sait que le CO2gazeux est utilisé pour un grand nombre d’applications industrielles parmi lesquelles on trouve des applications en alimentaire et notamment l’enrichissement des serres au CO2, l’anesthésie de volailles et des porcs au CO2, la carbonatation des boissons, le traitement des eaux etc….It is known that gaseous CO 2 is used for a large number of industrial applications among which there are applications in food and in particular the enrichment of greenhouses with CO 2 , the anesthesia of poultry and pigs with CO 2 , the carbonation beverages, water treatment, etc.
Typiquement, on sait que les fabricants de boissons ne peuvent pas utiliser du CO2trop « chaud », le CO2est généralement injecté dans l'eau à une température voisine de 2°C. Et l’on sait qu’en cas de CO2trop « chaud » la qualité de carbonatation ne sera pas optimale (ni optimale ni acceptable).Typically, we know that beverage manufacturers cannot use too “hot” CO 2 , CO 2 is generally injected into water at a temperature close to 2°C. And we know that if the CO 2 is too "hot", the carbonation quality will not be optimal (neither optimal nor acceptable).
On sait alors que différentes solutions techniques sont utilisées pour réaliser une telle vaporisation, notamment du CO2liquide, et l’on connaît notamment des équipements mettant en œuvre un échange thermique entre le CO2liquide et de l’eau (ou tout autre fluide tel huile, mélange d’eau glycolée ...etc.). On considérera dans ce qui suit pour des raison de simplicité les échangeurs cryogène/eau.We then know that different technical solutions are used to carry out such a vaporization, in particular of liquid CO 2 , and we know in particular of equipment implementing a heat exchange between liquid CO 2 and water (or any other fluid such as oil, mixture of glycol water, etc.). In what follows, for reasons of simplicity, cryogen/water exchangers will be considered.
Un tel équipement nécessite un apport d’énergie en continue pendant la vaporisation du gaz.Such equipment requires a continuous supply of energy during the vaporization of the gas.
Reste que de tels équipements font apparaître les problématiques suivantes :However, such equipment raises the following issues:
- l’échangeur utilisé est dimensionné pour éviter que l’eau ne puisse congeler à l’intérieur de l’échangeur, donnant lieu ainsi à une limite basse de dimensionnement. En effet, dans un tel équipement, les échangeurs de chaleurs permettent l'échange entre le CO2liquide (à -20°C, 20bar par exemple) et l'eau. On va donc dimensionner l'échangeur pour le maximum de débit de CO2et une température minimale d'eau à 10-15°C (ou moins). Par la suite, pour le même débit maximum de CO2,et une température basse de l’eau, l’échangeur est dimensionné pour qu’il n'y ait pas de risque de voir l'échangeur bouché par la congélation de l'eau pendant l'échange. En revanche, le CO2en sortie devient plus chaud, dès que la température de l'eau augmente.the exchanger used is dimensioned to prevent the water from freezing inside the exchanger, thus giving rise to a low dimensioning limit. Indeed, in such equipment, the heat exchangers allow the exchange between the liquid CO 2 (at -20°C, 20bar for example) and the water. We will therefore size the exchanger for the maximum CO 2 flow rate and a minimum water temperature of 10-15°C (or less). Subsequently, for the same maximum flow rate of CO 2 , and a low water temperature, the exchanger is sized so that there is no risk of seeing the exchanger clogged by the freezing of the water during the exchange. On the other hand, the CO 2 at the outlet becomes hotter as soon as the temperature of the water increases.
- selon le débit de gaz (CO2) à produire, et la consommation du site utilisateur en aval, pour des températures d’eau dépassant certaines limites (30°C dans certains cas) pour un débit donné d’eau, la température du CO2peut suivre la température d'entrée d’eau, qui peut atteindre jusqu’à 90°C (voire plus si c’est de la vapeur). En effet, l’eau est traditionnellement fournie par le site utilisateur lui-même, c’est l’eau que l’on qualifie la plupart du temps « d’eau de process », c’est l’eau qu’il utilise dans son procédé de production avec une température spécifique. Le site dépense de l'énergie pour refroidir l'eau, afin de pouvoir l'utiliser dans son procédé (refroidissement des machines, compresseurs, ...etc.). L’équipement de vaporisation va refroidir cette eau, en vaporisant le CO2, qui va être consommé par le site pour une application donnée, une carbonatation par exemple (double gain d'énergie).depending on the flow of gas (CO 2 ) to be produced, and the consumption of the downstream user site, for water temperatures exceeding certain limits (30°C in certain cases) for a given flow of water, the temperature of the CO 2 can follow the water inlet temperature, which can reach up to 90°C (or more if it is steam). Indeed, the water is traditionally provided by the user site itself, it is the water that is most of the time qualified as "process water", it is the water that it uses in its production process with a specific temperature. The site spends energy to cool the water, in order to be able to use it in its process (cooling of machines, compressors, etc.). The vaporization equipment will cool this water, by vaporizing the CO 2 , which will be consumed by the site for a given application, carbonation for example (double energy gain).
- on peut alors observer une surchauffe du CO2produit, dont la température peut alors poser des problèmes d’application chez les sites utilisateurs, dès qu’elle dépasse 15°C dans certains cas.we can then observe an overheating of the CO 2 produced, the temperature of which can then pose problems of application at the user sites, as soon as it exceeds 15°C in certain cases.
- les échangeurs actuels de vaporisation (y compris celui évoqué plus haut, d’échange thermique avec de l’eau), ne permettent pas d’ajuster, et notamment de baisser la température du gaz, par exemple du CO2, obtenu en sortie d’équipement.the current vaporization exchangers (including the one mentioned above, heat exchange with water), do not make it possible to adjust, and in particular to lower the temperature of the gas, for example CO 2 , obtained at the outlet of 'equipment.
Un des objectifs de la présente invention est alors de proposer une solution aux problématiques évoquées ci-dessus.One of the objectives of the present invention is then to propose a solution to the problems mentioned above.
Comme on le verra plus en détails dans ce qui suit, la présente invention propose d’injecter un gaz liquide dans le gaz obtenu en sortie de l’équipement de vaporisation, équipement de type mettant en œuvre un échangeur thermique cryogène liquide/eau.As will be seen in more detail in the following, the present invention proposes injecting a liquid gas into the gas obtained at the outlet of the vaporization equipment, equipment of the type implementing a liquid/water cryogenic heat exchanger.
On ajoutera préférentiellement dans le gaz obtenu en sortie de vaporiseur le même gaz liquide que celui qui doit être vaporisé (par exemple du CO2liquide dans le CO2gazeux de sortie pour un vaporiseur de CO2liquide).The same liquid gas as that to be vaporized will preferably be added to the gas obtained at the vaporizer outlet (for example liquid CO 2 in the gaseous CO 2 outlet for a liquid CO 2 vaporizer).
Cette injection peut être faite par une régulation automatique pour ajuster finement la température de sortie du gaz, elle peut également être effectuée par l’adoption d’un réglage fixe.This injection can be done by automatic regulation to finely adjust the gas outlet temperature, it can also be done by adopting a fixed setting.
Il s'agit du dosage entre CO2gazeux, après vaporisation, et CO2liquide. On pourrait le faire, automatiquement, à titre d’exemple, par une vanne progressive sur l'alimentation de CO2liquide, pour assurer un bon dosage et contrôler la température définitive de CO2.This is the proportioning between gaseous CO 2 , after vaporization, and liquid CO 2 . This could be done automatically, for example, by a progressive valve on the liquid CO 2 supply, to ensure a good dosage and control the final CO 2 temperature.
On peut, également, le faire manuellement, par exemple par un orifice calibré sur l'arrivée de CO2liquide, si on veut limiter uniquement la température du CO2gazeux.It can also be done manually, for example by a calibrated orifice on the arrival of liquid CO 2 , if it is desired to limit only the temperature of the gaseous CO 2 .

- Stockage de CO2liquideLiquid CO 2 storage
- CO2liquideliquid CO2
- CO2gazCO 2 gas
- Echangeur CO2/eauCO 2 /water exchanger
L’invention pourra par ailleurs adopter l’un des modes de mise en œuvre suivants :The invention may also adopt one of the following modes of implementation:
- le site utilisateur possède une source de vapeur d’eau qu’il souhaite valoriser et l’on utilise alors cette source de vapeur pour vaporiser le cryogène liquide, par exemple le CO2, cela selon l’une des mise en œuvre suivante :the user site has a source of water vapor that it wishes to use and this source of vapor is then used to vaporize the liquid cryogen, for example CO 2 , according to one of the following implementations:
- en injection directe dans l’échangeur 4 de la figure 1 annexée ;- by direct injection into the exchanger 4 of the appended figure 1;
- ou bien à l’aide d’un échangeur additionnel, en ajoutant une boucle d’échange eau/vapeur comme illustré dans la figure 3
On reconnaît sur la figure 3 les éléments d’installation suivants :Figure 3 shows the following installation elements:

Les avantages de la présente proposition technique peuvent être résumés ainsi :The advantages of this technical proposal can be summarized as follows:
- le refroidissement du gaz et l’ajustement de sa température en sortie de l’équipement de vaporisation.the cooling of the gas and the adjustment of its temperature at the outlet of the vaporization equipment.
- une meilleure utilisation du gaz par le site utilisateur (puisque typiquement certains sites utilisateurs, certains procédés, seraient fortement perturbés par l’arrivée d’un gaz par exemple d’un CO2trop chaud, et donc dans l’impossibilité de produire).better use of the gas by the user site (since typically certain user sites, certain processes, would be greatly disturbed by the arrival of a gas, for example CO 2 that is too hot, and therefore unable to produce).
- une meilleure stabilisation du procédé du site utilisateur, notamment pour les applications de carbonatation des boissons.better stabilization of the user site process, especially for beverage carbonation applications.
