Description

La présente invention est relative à un appareil de refroidissement et d'épuration d'air destiné à une unité de distillation cryogénique d'air. Dans un appareil de séparation d'air par distillation cryogénique, l'air est comprimé dans un compresseur et ensuite refroidi par échange de chaleur directe avec de l'air dans une tour de refroidissement. L'air refroidi est ensuite épuré. Les épurations dans les unités de séparation d'air permettent de retirer principalement l'eau et le CO2 de l'air avant l'entrée dans l'unité de distillation cryogénique, placée dans une boîte froide. Un ensemble de vannes et tuyauteries permettent le transit de l'air à épurer et l'azote impur qui sert à la io régénération des bouteilles d'épuration. Cet ensemble de vannes et tuyaux est posé «à plat» au sol et y présente un encombrement important. Le rapport de la hauteur et la longueur de l'ensemble est proche de 1 Lors de l'installation de cet ensemble de vannes et tuyaux à l'intérieur d'un nouveau bâtiment (pour des raisons de très grand froid ou chaud ou tout 15 autre) il est intéressant de réduire la largeur de cet ensemble pour réduire la largeur du bâtiment à construire. De même pour l'installation de cet ensemble dans un bâtiment existant (plutôt long et pas large) réduire la largeur de cet ensemble tuyauteries et vannes peut aider considérablement. Un des moyens de réduire la largeur de cet ensemble est, par 20 l'intermédiaire d'une conception des tuyauteries différente, d'allonger cet ensemble. Le rapport entre la hauteur et la largeur de l'ensemble devient très inférieur à 1. De ce fait l'entraxe de ces bouteilles d'épuration liées à cet ensemble va aussi s'allonger. 25 Selon l'invention, la tour de refroidissement d'air par contact direct avec l'eau est installée entre les deux bouteilles d'épuration. Selon un objet de l'invention, il est prévu un appareil de refroidissement et d'épuration d'un débit d'air comprenant une tour de refroidissement par contact direct avec de l'eau, deux bouteilles d'épuration, ayant chacune un axe 30 vertical, une conduite pour envoyer de l'eau à la tour de refroidissement, une conduite pour envoyer de l'air à la tour de refroidissement, une conduite pour envoyer de l'air refroidi de la tour aux bouteilles d'épuration, caractérisé en ce qu'il comprend un ensemble de vannes et de tuyaux permettant de relier les deux bouteilles à la tour de refroidissement, cet ensemble étant situé à l'intérieur d'un bâtiment et les deux bouteilles et la tour étant à l'extérieur du bâtiment, les deux bouteilles et l'ensemble étant placés de part et d'autre d'un mur du bâtiment, les bouteilles étant placés le long du mur et la tour étant disposée entre les deux bouteilles. Selon d'autres caractéristiques facultatives de l'appareil : - le centre de la tour vu d'en haut est située sur la ligne médiane entre les centres des deux bouteilles vu d'en haut ; - les centres des deux bouteilles et de la tour vu d'en haut forment une io ligne droite ; - les centres des deux bouteilles et de la tour vu d'en haute forment un triangle à angle obtus ; - le bâtiment contient également au moins un compresseur et/ou au moins une turbine et/ou au moins une colonne à distiller ; 15 - le rapport entre la dimension de l'ensemble dans le sens vertical et la dimension dans le sens horizontal est inférieur à 1 ; - le mur constitue le mur le plus long du bâtiment, le bâtiment étant de section rectangulaire ; - le rapport entre la longueur du mur et la largeur du bâtiment est de 20 préférence supérieur à 2. Selon un autre objet de l'invention, il est prévu un appareil de séparation d'air comprenant un appareil de refroidissement et d'épuration tel que décrit ci-dessus. L'invention sera décrite en plus de détail en se référant à la figure. Dans 25 la Figure 1 est illustré un appareil selon l'invention. L'appareil comprend une tour de refroidissement 1 par contact direct avec de l'eau, deux bouteilles d'épuration 3A, 3B pour épurer l'air en eau et en CO2 et un bâtiment 5 contenant au moins un ensemble 7 de tuyaux et de vannes pour permettre l'air provenant de la tour 1 d'être envoyé aux bouteilles 30 3A, 3B. Certains des tuyaux de l'ensemble 7 traversent le mur 9 du bâtiment 5. Le mur 9 est le mur le plus long du bâtiment 5 qui est de section rectangulaire. Le rapport entre la longueur du mur 9 et la largeur du bâtiment est de préférence supérieur à 2. The present invention relates to an air cooling and purification apparatus for a cryogenic air distillation unit. In a cryogenic distillation air separation apparatus, the air is compressed in a compressor and then cooled by direct heat exchange with air in a cooling tower. The cooled air is then purified. The purges in the air separation units mainly remove water and CO2 from the air before entering the cryogenic distillation unit, placed in a cold box. A set of valves and pipes allow the transit of the air to be purified and the impure nitrogen which serves for the regeneration of the purification bottles. This set of valves and pipes is placed "flat" on the ground and has a large footprint. The ratio of the height and length of the assembly is close to 1 When installing this set of valves and pipes inside a new building (for reasons of very hot or cold weather or any 15 other) it is interesting to reduce the width of this set to reduce the width of the building to build. Likewise for the installation of this set in an existing building (rather long and not wide) reducing the width of this whole pipework and valves can help considerably. One of the ways to reduce the width of this assembly is, through a different piping design, to lengthen this assembly. The ratio between the height and the width of the assembly becomes much smaller than 1. As a result, the spacing of these cleaning bottles related to this set will also lengthen. According to the invention, the cooling tower of air by direct contact with water is installed between the two purification bottles. According to one object of the invention, there is provided an apparatus for cooling and purifying an air flow comprising a cooling tower by direct contact with water, two purification bottles, each having an axis Vertical, a conduit for supplying water to the cooling tower, a conduit for supplying air to the cooling tower, a conduit for supplying cooled air from the tower to the purification bottles, characterized in that it comprises a set of valves and pipes for connecting the two bottles to the cooling tower, this assembly being located inside a building and the two bottles and the tower being outside the building. building, the two bottles and the assembly being placed on either side of a wall of the building, the bottles being placed along the wall and the tower being disposed between the two bottles. According to other optional features of the apparatus: - the center of the tower seen from above is located on the center line between the centers of the two bottles seen from above; the centers of the two bottles and the tower seen from above form a straight line; - the centers of the two bottles and the tower seen from above form a triangle with an obtuse angle; the building also contains at least one compressor and / or at least one turbine and / or at least one distillation column; The ratio between the dimension of the assembly in the vertical direction and the dimension in the horizontal direction is less than 1; - the wall constitutes the longest wall of the building, the building being of rectangular section; the ratio between the length of the wall and the width of the building is preferably greater than 2. According to another object of the invention, there is provided an air separation apparatus comprising a cooling and purification apparatus such as as described above. The invention will be described in more detail with reference to the figure. In Figure 1 there is illustrated an apparatus according to the invention. The apparatus comprises a cooling tower 1 by direct contact with water, two purifying bottles 3A, 3B for purifying air in water and CO2 and a building 5 containing at least one set 7 of pipes and valves to allow air from the tower 1 to be sent to the bottles 30 3A, 3B. Some of the pipes of the assembly 7 pass through the wall 9 of the building 5. The wall 9 is the longest wall of the building 5 which is of rectangular section. The ratio between the length of the wall 9 and the width of the building is preferably greater than 2.

Le rapport entre la dimension de l'ensemble 7 dans le sens vertical et la dimension dans le sens horizontal est inférieur à 1. Les deux bouteilles 3A, 3B et la tour sont disposées le long du mur 9 de sorte que leurs centres vus d'en haut forment une ligne droite parallèle au mur. The ratio between the dimension of the assembly 7 in the vertical direction and the dimension in the horizontal direction is less than 1. The two bottles 3A, 3B and the tower are arranged along the wall 9 so that their centers seen from at the top, form a straight line parallel to the wall.

La tour est disposée sur la ligne médiane entre les deux bouteilles. La tour 1 peut être légèrement plus proche ou plus loin du mur 9 que les deux bouteilles 3A, 3B de sorte que les centres de la tour et des deux bouteilles forment un triangle à angle obtus. io 30 The tower is arranged on the center line between the two bottles. The tower 1 may be slightly closer to or further from the wall 9 than the two bottles 3A, 3B so that the centers of the tower and the two bottles form an obtuse angle triangle. io 30
