Description
La présente invention est relative à un appareil de séparation d’air comprenant au moins un élément souterrain.The present invention relates to an air separation apparatus comprising at least one subterranean element.
Les unités de séparation d’air sont actuellement arrangées de façon horizontale avec peu ou pas d’équipements qui se superposent. L’empreinte au sol est en général grande ce qui crée des coûts de terrain de génie civil et de montage. II a déjà été proposé dans le passé des modes d’arrangement modulaire pour facilité le transport et le montage. Toutefois ils se calquent sur l’organisation actuelle d’une unité de séparation d’air.The air separation units are currently arranged horizontally with little or no overlapping equipment. The footprint is generally large which creates field costs for civil engineering and assembly. It has been proposed in the past of modular arrangement modes for ease of transport and assembly. However, they rely on the current organization of an air separation unit.
Selon un objet de l’invention, il est prévu un appareil de séparation d’air par distillation cryogénique comprenant au moins une colonne de distillation, une unité de compression d’air d’alimentation, une unité d’épuration d’air comprimé, une unité d’échange thermique indirect dans lequel au moins un éléments est disposé sous le sol, cet élément pouvant être choisi dans le groupe : une partie inférieure de la colonne de distillation, l’unité de compression d’air d’alimentation, l’unité d’épuration d’air comprimé, l’unité d’échange thermique indirect, une unité de compression d’un produit de l’appareil, une pompe, une turbine, une tour de refroidissement, un groupe frigorigène, un sous-refroidisseur, au moins un stockage de liquide provenant de la distillation, une unité de surpression d’air.According to an object of the invention, there is provided a cryogenic distillation air separation apparatus comprising at least one distillation column, a feed air compression unit, a compressed air purification unit, an indirect heat exchange unit in which at least one element is disposed under the ground, this element being selectable from the group: a lower part of the distillation column, the supply air compression unit, the compressed air purification unit, the indirect heat exchange unit, a unit for compressing a product of the apparatus, a pump, a turbine, a cooling tower, a refrigerant group, a sub-unit cooler, at least one liquid storage from the distillation, an air booster unit.
Selon d’autres objets facultatifs : une partie supérieure de la colonne de distillation est à l’air libre, l’appareil comprend au moins une prise d’air situé au niveau du sol relié à l’unité de compression d’air d’alimentation disposé sous le sol. le filtre d’air est situé au niveau du sol. au moins un bâtiment administratif et/ou au moins une salle de contrôle et/ou un magasin de pièces détachées est situé au niveau du sol et/ou une unité de refroidissement d’air par lavage à l’eau. l’au moins un élément disposé sous le sol se trouve à une profondeur d’au moins 5 m, voire d’au moins 10m, en dessous de la surface. au plus 20%, voire 10% de la hauteur de la colonne de distillation se trouve en dessous du sol.According to other optional objects: an upper part of the distillation column is in the open air, the apparatus comprises at least one air intake located at ground level connected to the air compression unit of feeding arranged under the ground. the air filter is located at ground level. at least one administrative building and / or at least one control room and / or a spare parts store is located at ground level and / or a water-cooling unit. the at least one element disposed under the ground is at a depth of at least 5 m, or even at least 10 m, below the surface. no more than 20%, or even 10% of the height of the distillation column is below the ground.
La présente invention permet de libérer de l’espace au sol, grâce à la création d’au moins un niveau en sous sol où est disposé au moins un élément de l’appareil de séparation d’air. II en résulte un enfouissement d’au moins un équipement dont l’accès est permis par une cage d’escalier du style de celle desservant les parkings souterrains. De par sa taille la boîte froide contenant la colonne de distillation reste en majorité apparente et aérienne. Sur la surface ainsi libérée et à l’aplomb de certains équipements de l’usine par exemple, des prises d’air, des filtres, des cheminées peuvent prendre place.The present invention frees space on the ground, through the creation of at least one level in the basement where is disposed at least one element of the air separation apparatus. This results in a burial of at least one equipment whose access is allowed by a stairwell of the style of the one serving the underground car parks. Due to its size, the cold box containing the distillation column remains mostly visible and aerial. On the surface thus released and in line with certain equipment of the factory for example, air intakes, filters, chimneys can take place.
Par exemple les bâtiments administratifs, salles de contrôle, un magasin de pièces détachées, accès seront eux aussi disposés sur la surface libérée et communiqueront avec la partie technique sous terraine. L’invention sera décrite de manière plus détaillée en se référant à la figure qui illustre des appareils selon l’invention.For example administrative buildings, control rooms, a spare parts store, access will also be arranged on the released surface and will communicate with the technical part underground. The invention will be described in more detail with reference to the figure which illustrates apparatus according to the invention.
Au sol l’appareil comprend la partie supérieure d’une colonne de distillation, la partie inférieure constituant au plus 20% de la hauteur, voire au plus 10% de la hauteur, étant enfouie sous terre. L’appareil comprend également au sol un bâtiment administratif, au moins une salle de contrôle et un magasin de pièces détachées est situé au niveau du sol ainsi qu’une unité de refroidissement d’air comprimé par lavage à l’eau. A un niveau d’au moins 5m, voire au moins 10m sous la surface sont localisés l’unité de compression d’air d’alimentation, l’unité d’épuration d’air comprimé, l’unité d’échange thermique indirect, éventuellement une unité de compression d’un produit de l’appareil, une pompe, une turbine, une tour de refroidissement, un groupe frigorigène, un sous-refroidisseur, au moins un stockage de liquide provenant de la distillation, une unité de surpression d’air.On the ground the apparatus comprises the upper part of a distillation column, the lower part constituting not more than 20% of the height, or even not more than 10% of the height, being buried underground. The apparatus also includes an administrative building on the ground, at least one control room and a spare parts store is located at ground level and a unit for cooling compressed air by washing with water. At a level of at least 5m, or even at least 10m below the surface are located the supply air compression unit, the compressed air purification unit, the indirect heat exchange unit, optionally a unit for compressing a product of the apparatus, a pump, a turbine, a cooling tower, a refrigerant group, a sub-cooler, at least one liquid storage from the distillation, a booster unit of 'air.
Ces éléments sont localisés, avec l’isolation qui convient, dans une salle par exemple au troisième sous-sol.These elements are located, with the appropriate insulation, in a room for example the third basement.
