Des exemples de réalisation de l'invention vont maintenant être décrits en regard des dessins annexés, sur lesquels :

  • la Figure 1 représente schématiquement, en vue de dessus, un premier mode de réalisation de l'installation suivant l'invention;
  • la Figure 2 est une vue analogue d'un deuxième mode de réalisation de l'installation suivant l'invention; et
  • la Figure 3 représente schématiquement, en perspective, une partie d'un agencement préféré d'un module de ces installations.
Examples of embodiments of the invention will now be described with reference to the appended drawings, in which:
  • Figure 1 shows schematically, in top view, a first embodiment of the installation according to the invention;
  • Figure 2 is a similar view of a second embodiment of the installation according to the invention; and
  • Figure 3 shows schematically, in perspective, part of a preferred arrangement of a module of these installations.

L'installation représentée à la Figure 1 comprend un module ou groupe de compression d'air 1, deux bouteilles d'épuration d'air (dessication-décarbonatation) par adsorption 2A, 2B à fonctionnement alterné, un module "chaud" 3, un module "froid" 4, une double colonne de distillation 5, et un ensemble de tuyaux de liaison rectilignes 6.The installation represented in FIG. 1 comprises an air compression module or group 1, two air purification bottles (desiccation-decarbonation) by adsorption 2A, 2B with alternating operation, a "hot" module 3, a "cold" module 4, a double distillation column 5, and a set of straight connecting pipes 6.

Chacun des sous-ensembles ci-dessus est représenté de façon très schématique, mais tous leurs constituants sont, en soi, classiques, et leurs liaisons ainsi que leur fonctionnement correspondent à ce que l'on rencontre habituellement dans les installations de distillation d'air à double colonne. On ne décrira donc les éléments 1 à 6 que de façon sommaire.Each of the above sub-assemblies is represented very schematically, but all their constituents are, in themselves, conventional, and their connections as well as their functioning correspond to what is usually encountered in air distillation installations. double column. Elements 1 to 6 will therefore only be described in a summary manner.

Ainsi, le module 1 comprend, sur un socle 7, un moteur électrique 8 entraînant un compresseur principal 9, et les réfrigérants intermédiaires 10 du compresseur. Le refoulement de ce dernier aboutit à un raccord 11 de sortie du module 1.Thus, the module 1 comprises, on a base 7, an electric motor 8 driving a main compressor 9, and the intermediate refrigerants 10 of the compressor. The discharge of the latter leads to a connector 11 for output of the module 1.

Les bouteilles 2A, 2B sont des bouteilles d'adsorption classiques, munies chacune de deux raccords, respectivement 12A, 12B.The bottles 2A, 2B are bottles conventional adsorption, each provided with two connections, respectively 12A, 12B.

Le module 3 comprend une ossature parallélépipédique 13 dans laquelle sont fixés l'ensemble des éléments "chauds" de l'installation autres que le module de compression et les bouteilles d'épuration : le réfrigérant final 14 du compresseur, relié à un raccord d'entrée 15 disposé en regard du raccord 11, et un groupe frigorifique 17 monté en série avec le réfrigérant 14, un réchauffeur 18 de gaz de régénération de l'adsorbant, la conduite 19 d'évacuation du gaz résiduaire de la colonne, muni d'un silencieux 20, et également l'ensemble des organes de contrôle, de commande et d'instrumentation relatifs aux éléments 14 à 20, schématisé en 21. Le module 3 comporte encore deux raccords 22A, 22B pour chaque bouteille 2A, 2B respectivement, et des raccords 23 de liaison avec le module froid 4, au nombre de trois dans cet exemple.The module 3 comprises a parallelepipedic frame 13 in which are fixed all the "hot" elements of the installation other than the compression module and the purification bottles: the final refrigerant 14 of the compressor, connected to a connection of inlet 15 disposed opposite the connector 11, and a refrigeration unit 17 mounted in series with the coolant 14, a heater 18 for adsorbent regeneration gas, the pipe 19 for evacuating the residual gas from the column, provided with a silencer 20, and also all the control, command and instrumentation members relating to the elements 14 to 20, shown diagrammatically at 21. The module 3 also has two connections 22A, 22B for each bottle 2A, 2B respectively, and connections 23 for connection with the cold module 4, three in number in this example.

Le module 4 comprend la ligne d'échange thermique principale 24, constituée de plusieurs corps d'échangeurs parallélélipédiques du type à plaques brasées, un sous-refroidisseur 25, les accessoires froids de l'installation telle que des pompes cryogéniques 26 et des turbines 27, et l'ensemble des organes de contrôle, de commande et d'instrumentation relatifs aux éléments 24 à 27, schématisé en 28. Le module 4 comporte encore des raccords 29 d'entrée/sortie de la ligne d'échange thermique, en nombre égal aux raccords 23 et disposés en regard de ceux-ci, et des raccords 30 de liaison à la colonne 5. L'ensemble des éléments 24 à 30 sont montés dans une ossature parallélépipédique 31. L'ensemble des parties froides des éléments froids (échangeurs 24 et 25, corps de vannes cryogéniques, pompes 26, turbines 27, etc) sont isolées thermiquement, par exemple au moyen de perlite.The module 4 comprises the main heat exchange line 24, consisting of several bodies of parallelelipedic exchangers of the brazed plate type, a sub-cooler 25, the cold accessories of the installation such as cryogenic pumps 26 and turbines 27 , and all of the control, command and instrumentation members relating to elements 24 to 27, shown diagrammatically at 28. The module 4 also includes fittings 29 for input / output of the heat exchange line, in number equal to the connections 23 and arranged opposite them, and of the connections 30 for connection to the column 5. All of the elements 24 to 30 are mounted in a parallelepiped frame 31. All of the cold parts of the cold elements ( heat exchangers 24 and 25, cryogenic valve bodies, pumps 26, turbines 27, etc.) are thermally insulated, for example by means of perlite.

On comprendra que, suivant, l'installation considérée, les éléments des modules 3 et 4 peuvent varier en type et en nombre. De plus, ces modules comportent toutes les conduites de liaison de leurs éléments les uns aux autres, avec les vannes automatiques et/ou commandées à distance correspondantes.It will be understood that, depending on the installation considered, the elements of modules 3 and 4 may vary in type and number. In addition, these modules include all the connecting pipes from their elements to each other, with the corresponding automatic and / or remote-controlled valves.

La colonne 5 est une double colonne comprenant une colonne moyenne pression surmontée d'une colonne basse pression, avec un vaporiseur-condenseur principal qui met en relation d'échange thermique la vapeur de tête (azote) de la colonne moyenne pression et le liquide de cuve (oxygène) de la colonne basse pression. Cette double colonne, dont la hauteur est considérablement supérieure à celle des modules 3 et 4, est isolée sous vide par une paroi cylindrique 32 d'où émergent des raccords 33 en nombre égal aux raccords 30 et disposés en regard de ceux-ci.Column 5 is a double column comprising a medium pressure column surmounted by a low pressure column, with a main vaporizer-condenser which brings the overhead vapor (nitrogen) of the medium pressure column into contact with heat exchange liquid. low pressure column tank (oxygen). This double column, the height of which is considerably greater than that of modules 3 and 4, is vacuum-insulated by a cylindrical wall 32 from which emerge fittings 33 equal in number to the fittings 30 and arranged opposite them.

La Demanderesse a constaté que même pour des installations de taille importante, par exemple produisant plusieurs centaines de tonnes par jour d'oxygène, même du type à vaporisation d'oxygène liquide sous pression, il est possible de réaliser de la manière décrite plus haut des modules 3 et 4 de forme générale parallélépipédique dont les dimensions extérieures permettent le transport routier.The Applicant has found that even for large installations, for example producing several hundred tonnes per day of oxygen, even of the type with vaporization of liquid oxygen under pressure, it is possible to carry out in the manner described above. modules 3 and 4 of generally parallelepiped shape whose external dimensions allow road transport.

Ainsi, sur le site, il suffit de positionner les sous-ensembles 1, 2A, 2B, 3, 4 et 5, puis de relier les raccords correspondants par les tuyaux droits 6.Thus, on the site, it suffices to position the sub-assemblies 1, 2A, 2B, 3, 4 and 5, then to connect the corresponding fittings by the straight pipes 6.

Pour les installations de taille relativement modérée ou petite, et/ou de conception simplifiée, on peut même, comme représenté sur la Figure 2, réunir les modules 3 et 4 en un module unique 103 transportable par route, ce module contenant tous les éléments nécessaires au fonctionnement de l'installation, montés dans une ossature parallélépipédique 113 équipée de tous les raccords 15, 22A, 22B et 30, l'ensemble des organes de contrôle, de commande et d'instrumentation étant rassemblés d'un côté du module, en 121. L'assemblage sur site est alors encore plus simple que dans le cas de la Figure 1.For installations of relatively moderate or small size, and / or of simplified design, it is even possible, as shown in Figure 2, to combine modules 3 and 4 into a single module 103 transportable by road, this module containing all the necessary elements during operation of the installation, mounted in a parallelepipedic frame 113 equipped with all fittings 15, 22A, 22B and 30, all of the control, command and instrumentation members being assembled on one side of the module, at 121. The assembly on site is then even simpler than in the case of Figure 1.

Comme représenté sur la Figure 3, le ou chaque module 3, 4 ou 103 peut comporter sur une face, dans sa partie inférieure, un compartiment 34 très facile d'accès où sont regroupés l'ensemble des organes de contrôle, de commande et d'instrumentation 21, 28 ou 121. En particulier, dans le module froid 4 ou dans le module unique 103, représentés sur la Figure 3, la ligne d'échange thermique 24 peut surplomber pour partie le sous-refroidisseur 25 et pour partie le compartiment 34.As shown in Figure 3, the or each module 3, 4 or 103 may have on one side, in its lower part, a compartment 34 very easy to access where are grouped all the control, command and control elements. instrumentation 21, 28 or 121. In particular, in the cold module 4 or in the single module 103, represented in FIG. 3, the heat exchange line 24 can partly overhang the sub-cooler 25 and partly the compartment 34.

De plus, dans l'installation de la Figure 1, on peut disposer les ensembles 21 et 28 dans des compartiments en vis-à-vis ouverts l'un vers l'autre, et prévoir entre eux, entre les modules 3 et 4, un poste de travail 35 ayant un accès direct à tous les organes de contrôle, de commande et d'instrumentation de l'installation.In addition, in the installation of FIG. 1, the assemblies 21 and 28 can be placed in facing compartments open towards one another, and provide between them, between the modules 3 and 4, a work station 35 having direct access to all the control, command and instrumentation bodies of the installation.

Bien entendu, l'installation comporte en outre les divers équipements habituels liés à l'alimentation en courant électrique, en eau de refroidissement et éventuellement en gaz auxiliaires, ces équipements étant reliés aux composants correspondants des modules décrits ci-dessus.Of course, the installation also includes the various usual equipment linked to the supply of electric current, cooling water and possibly auxiliary gas, this equipment being connected to the corresponding components of the modules described above.

Par ailleurs, notamment dans le cas d'installations de petite taille, on peut envisager de monter les bouteilles d'épuration 2A, 2B dans l'ossature unique ou dans l'une au moins des deux ossatures, et/ou le groupe de compression 1 dans l'ossature unique ou dans l'ossature "chaude".Furthermore, in particular in the case of small installations, it is possible to envisage mounting the purification bottles 2A, 2B in the single framework or in at least one of the two frameworks, and / or the compression group. 1 in the single frame or in the "hot" frame.
