Definitions

  • the heat exchange device is for example intended to be placed in a cooling train of a plant for the production of liquefied hydrocarbons, in particular a plant for liquefying natural gas.
  • the liquefaction of natural gas has many advantages in terms of transport and conditioning of hydrocarbons. An increasing amount of the natural gas produced is liquefied in significant capacity liquefaction plants.
  • the first fluid is for example propane.
  • Propane is introduced in liquid or two-phase form into the interior volume of the radiator grille, and is vaporized by recovering the calories extracted from the natural gas circulating in the bundle of tubes. Natural gas is thus precooled during its passage through the heat exchange device.
  • a device of the aforementioned type is used to cool or condense refrigerants (instead of natural gas) in refrigeration loops.
  • the heating of the first fluid generates its partial vaporization and the generation of a entrained fluid which is recompressed before being reliquefied.
  • the entrained fluid generally comprises droplets of liquid, which must be separated from the gas flow, before this is introduced into the compressor.
  • the heat exchange device is generally provided with a disengagement member, formed for example of an openwork lattice, through which the entrained fluid passes to eliminate the droplets.
  • the disengagement member is located above the volume of liquid propane, at a minimum distance from it, so as not to soak in the liquid propane.
  • the liquid propane present around the tube bundle undergoes numerous turbulences, due to its partial vaporization, which increases the minimum distance between the disengagement member and the tube bundle.
  • the size of the heat exchange device is high. Consequently, in a natural gas liquefaction installation, in particular of large capacity, the liquefaction trains occupy a large space. For example, in some units, the length of the liquefaction trains can reach several tens of meters. This is acceptable when the available ground area is large, but can be problematic in other contexts, where the available area is lower.
  • An object of the invention is to reduce the size of the heat exchange devices in an installation for producing cooled and / or liquefied fluid, without affecting their efficiency and their operation.
  • the subject of the invention is a device of the aforementioned type as in claim 1.

Description

La présente invention concerne un dispositif d'échange thermique entre un premier fluide destiné à être vaporisé et un deuxième fluide destiné à être refroidi et/ou condensé, comprenant :

  • une calandre, définissant un volume intérieur de réception du premier fluide s'étendant suivant un axe longitudinal ;
  • un faisceau de tubes disposé dans la calandre, le faisceau de tubes s'étendant longitudinalement dans le volume intérieur pour recevoir le deuxième fluide ;
  • un organe de désengagement, propre à effectuer une séparation liquide vapeur dans le fluide entraîné à partir du volume intérieur, l'organe de désengagement étant disposé au-dessus du faisceau de tubes. La présente invention concerne plus particulièrement un dispositif tel que décrit par le préambule de la revendication 1 et illustré par le document WO 01/44730A1 .
The present invention relates to a heat exchange device between a first fluid intended to be vaporized and a second fluid intended to be cooled and / or condensed, comprising:
  • a calender, defining an interior volume for receiving the first fluid extending along a longitudinal axis;
  • a bundle of tubes disposed in the shell, the bundle of tubes extending longitudinally in the interior volume to receive the second fluid;
  • a disengagement member, suitable for effecting a liquid vapor separation in the entrained fluid from the interior volume, the disengagement member being disposed above the bundle of tubes. The present invention relates more particularly to a device as described by the preamble of claim 1 and illustrated by the document WO 01 / 44730A1 .

Le dispositif d'échange thermique est par exemple destiné à être placé dans un train de refroidissement d'une installation de production d'hydrocarbures liquéfiés, en particulier une installation de liquéfaction de gaz naturel.The heat exchange device is for example intended to be placed in a cooling train of a plant for the production of liquefied hydrocarbons, in particular a plant for liquefying natural gas.

La liquéfaction du gaz naturel présente de nombreux avantages en termes de transport et de conditionnement des hydrocarbures. Une quantité croissante du gaz naturel produit est liquéfiée dans des installations de liquéfaction de capacités significatives.The liquefaction of natural gas has many advantages in terms of transport and conditioning of hydrocarbons. An increasing amount of the natural gas produced is liquefied in significant capacity liquefaction plants.

Pour pré-refroidir le gaz naturel, un dispositif d'échange thermique du type précité est fréquemment utilisé. Dans ce cas, le premier fluide est par exemple du propane. Le propane est introduit sous forme liquide ou diphasique dans le volume intérieur de la calandre, et est vaporisé en récupérant les calories extraites du gaz naturel circulant dans le faisceau de tubes. Le gaz naturel est ainsi pré-refroidi lors de son passage dans le dispositif d'échange thermique.To pre-cool natural gas, a heat exchange device of the aforementioned type is frequently used. In this case, the first fluid is for example propane. Propane is introduced in liquid or two-phase form into the interior volume of the radiator grille, and is vaporized by recovering the calories extracted from the natural gas circulating in the bundle of tubes. Natural gas is thus precooled during its passage through the heat exchange device.

En variante, un dispositif du type précité est utilisé pour refroidir ou condenser des fluides réfrigérant (en lieu et place du gaz naturel) dans des boucles de réfrigération.Alternatively, a device of the aforementioned type is used to cool or condense refrigerants (instead of natural gas) in refrigeration loops.

Le réchauffage du premier fluide engendre sa vaporisation partielle et la génération d'un fluide entraîné qui est recomprimé avant d'être reliquéfié.The heating of the first fluid generates its partial vaporization and the generation of a entrained fluid which is recompressed before being reliquefied.

Le fluide entraîné comporte généralement des gouttelettes de liquide, qui doivent être séparées du flux gazeux, avant que celui-ci ne soit introduit dans le compresseur.The entrained fluid generally comprises droplets of liquid, which must be separated from the gas flow, before this is introduced into the compressor.

À cet effet, le dispositif d'échange thermique est généralement muni d'un organe de désengagement, formé par exemple d'un treillis ajouré, à travers lequel le fluide entraîné passe pour éliminer les gouttelettes.To this end, the heat exchange device is generally provided with a disengagement member, formed for example of an openwork lattice, through which the entrained fluid passes to eliminate the droplets.

L'organe de désengagement est situé au-dessus du volume de propane liquide, à une distance minimale de celui-ci, afin de ne pas tremper dans le propane liquide. De plus, le propane liquide présent autour du faisceau de tubes subit de nombreuses turbulences, du fait de sa vaporisation partielle, ce qui augmente la distance minimale entre l'organe de désengagement et le faisceau de tubes.The disengagement member is located above the volume of liquid propane, at a minimum distance from it, so as not to soak in the liquid propane. In addition, the liquid propane present around the tube bundle undergoes numerous turbulences, due to its partial vaporization, which increases the minimum distance between the disengagement member and the tube bundle.

Compte tenu des capacités de refroidissement nécessaires à la liquéfaction, l'encombrement du dispositif d'échange thermique est élevé. Par suite, dans une installation de liquéfaction de gaz naturel, notamment de grande capacité, les trains de liquéfaction occupent un espace important. Par exemple, dans certaines unités, la longueur des trains de liquéfaction peut atteindre plusieurs dizaines de mètres. Ceci est acceptable lorsque l'emprise au sol disponible est importante, mais peut poser problème dans d'autres contextes, où l'emprise disponible est plus faible.Given the cooling capacities necessary for liquefaction, the size of the heat exchange device is high. Consequently, in a natural gas liquefaction installation, in particular of large capacity, the liquefaction trains occupy a large space. For example, in some units, the length of the liquefaction trains can reach several tens of meters. This is acceptable when the available ground area is large, but can be problematic in other contexts, where the available area is lower.

Un but de l'invention est de diminuer la taille des dispositifs d'échange thermique dans une installation de production de fluide refroidi et/ou liquéfié, sans nuire à leur efficacité et à leur fonctionnement.An object of the invention is to reduce the size of the heat exchange devices in an installation for producing cooled and / or liquefied fluid, without affecting their efficiency and their operation.

Dans tout ce qui suit, les termes « amont » et « aval » s'entendent par rapport au sens normal de circulation d'un fluide dans le dispositif d'échange thermique.In all that follows, the terms “upstream” and “downstream” are understood with respect to the normal direction of circulation of a fluid in the heat exchange device.

Un premier dispositif 10 d'échange thermique selon l'invention est illustré par la figure 1, dans une installation 12 de production de fluide, en particulier une installation de liquéfaction de gaz naturel.A first heat exchange device 10 according to the invention is illustrated by the figure 1 , in a fluid production installation 12, in particular a natural gas liquefaction installation.

Le dispositif d'échange thermique 10 est destiné à placer en relation d'échange thermique un premier fluide circulant dans un cycle de réfrigération avec un deuxième fluide de l'installation 12. Le premier fluide est propre à se réchauffer et à se vaporiser au moins en partie dans le dispositif 10 pour engendrer un fluide entrainé. Le deuxième fluide est propre à être refroidi, et avantageusement liquéfié dans le dispositif 10.The heat exchange device 10 is intended to place in heat exchange relation a first fluid circulating in a refrigeration cycle with a second fluid of the installation 12. The first fluid is capable of heating and vaporizing at least partly in the device 10 for generating a entrained fluid. The second fluid is suitable for being cooled, and advantageously liquefied in the device 10.

Dans cet exemple, le premier fluide est un hydrocarbure, par exemple du propane, ou un mélange d'hydrocarbures.In this example, the first fluid is a hydrocarbon, for example propane, or a mixture of hydrocarbons.

Le deuxième fluide est avantageusement du gaz naturel ou un mélange réfrigérant. Il est sous forme gazeuse ou diphasique en amont du dispositif d'échange thermique 10. Le deuxième fluide est sous forme liquide ou diphasique ou gazeux après son passage dans le dispositif d'échange thermique 10.The second fluid is advantageously natural gas or a cooling mixture. It is in gaseous or two-phase form upstream of the heat exchange device 10. The second fluid is in liquid or two-phase or gaseous form after it has passed through the heat exchange device 10.

L'installation 12 comprend une source 14 de deuxième fluide sous forme gazeuse, disposée en amont du dispositif d'échange thermique 10, et une capacité 16 de récupération du deuxième fluide liquéfié, disposée en aval du dispositif d'échange thermique 10.The installation 12 comprises a source 14 of second fluid in gaseous form, disposed upstream of the heat exchange device 10, and a capacity 16 for recovering the second liquefied fluid, disposed downstream of the heat exchange device 10.

L'installation 12 comprend en outre un cycle de réfrigération 18, dans lequel circule le premier fluide.The installation 12 further comprises a refrigeration cycle 18, in which the first fluid circulates.

Le cycle de réfrigération 18 comprend par exemple, en amont du dispositif 10, un organe de détente 20, tel qu'une vanne de détente statique ou une turbine de détente dynamique, propre à détendre le premier fluide pour entraîner son refroidisement, et un séparateur 22 gaz/liquide, disposé entre l'organe de détente 20 et le dispositif d'échange thermique 10. Le cycle de réfrigération 18 comporte un compresseur 24, disposé en aval du dispositif d'échange thermique 10.The refrigeration cycle 18 comprises for example, upstream of the device 10, an expansion member 20, such as a static expansion valve or a dynamic expansion turbine, capable of expanding the first fluid to cause its cooling, and a separator 22 gas / liquid, disposed between the expansion member 20 and the heat exchange device 10. The refrigeration cycle 18 comprises a compressor 24, disposed downstream of the heat exchange device 10.

En référence à la figure 1, le dispositif d'échange thermique 10 est de type à calandre et faisceau de tubes.With reference to the figure 1 , the heat exchange device 10 is of the shell and tube bundle type.

Il comporte une calandre 30 allongée, un faisceau de tubes 32 disposé dans un volume intérieur 34 de la calandre 30 et un distributeur/collecteur 36, propre à distribuer le deuxième fluide dans le faisceau de tubes 32 et à le collecter à sa sortie du faisceau de tubes 32. Le faisceau de tubes est représenté schématiquement par un seul tube sur la figure 1.It comprises an elongated calender 30, a bundle of tubes 32 disposed in an interior volume 34 of the calender 30 and a distributor / collector 36, suitable for distributing the second fluid in the bundle of tubes 32 and for collecting it at its exit from the bundle of tubes 32. The bundle of tubes is represented schematically by a single tube on the figure 1 .

Le dispositif d'échange thermique 10 comporte en outre au moins une entrée inférieure 38 d'introduction du premier fluide dans le volume intérieur 34, au moins une sortie inférieure 40 de purge d'un excès de premier fluide sous forme liquide, et au moins une sortie supérieure 42 d'évacuation du flux gazeux entraîné, disposée au-dessus de la calandre 30.The heat exchange device 10 further comprises at least one lower inlet 38 for introducing the first fluid into the interior volume 34, at least one lower outlet 40 for purging an excess of first fluid in liquid form, and at least an upper outlet 42 for discharging the entrained gas flow, disposed above the grille 30.

Le dispositif d'échange thermique 10 comprend de plus un organe de désengagement 44, interposé entre le faisceau de tubes 32 et la sortie supérieure 42 pour éliminer les gouttelettes de liquide présentes dans le flux gazeux entraîné à travers la sortie supérieure 42.The heat exchange device 10 further comprises a disengagement member 44, interposed between the bundle of tubes 32 and the upper outlet 42 to eliminate the droplets of liquid present in the gas flow entrained through the upper outlet 42.

La calandre 30 s'étend suivant un axe longitudinal A-A' d'allongement, qui dans l'exemple représenté sur la figure 1, est un axe horizontal.The calender 30 extends along a longitudinal axis AA ′ of elongation, which in the example shown in the figure 1 , is a horizontal axis.

Elle présente une paroi 46 délimitant intérieurement le volume intérieur 34, une pluralité de chicanes 48 de support du faisceau de tubes 32, et dans cet exemple, une paroi interne 50 de rétention du premier fluide autour du faisceau de tubes 32, faisant saillie verticalement dans le volume intérieur 34, au voisinage de l'extrémité du faisceau de tubes 32.It has a wall 46 internally delimiting the interior volume 34, a plurality of baffles 48 for supporting the bundle of tubes 32, and in this example, an internal wall 50 for retaining the first fluid around the bundle of tubes 32, projecting vertically in the interior volume 34, in the vicinity of the end of the bundle of tubes 32.

Le faisceau de tubes 51 comporte par exemple plus de 5000 tubes.The bundle of tubes 51 comprises for example more than 5000 tubes.

Chaque tube 51 présente un diamètre interne notamment compris entre 1,6 cm (5/8 de pouce) et 3,8 cm (1.5 pouce). Les tubes 51 présentent de préférence une section circulaire. Les tubes sont dépourvus de matériau de remplissage solide, comme par exemple un packing ou du catalyseur.Each tube 51 has an internal diameter in particular between 1.6 cm (5/8 inch) and 3.8 cm (1.5 inch). The tubes 51 preferably have a circular section. The tubes are devoid of solid filling material, such as packing or catalyst.

Dans cet exemple, chaque tube 51 présente un tronçon amont 52 et un tronçon aval 54 s'étendant linéairement parallèlement à l'axe A-A', et un tronçon intermédiaire coudé 56 raccordant les tronçons 52, 54. Les tronçons 52, 54 débouchent en amont et en aval dans le distributeur/collecteur 36.In this example, each tube 51 has an upstream section 52 and a downstream section 54 extending linearly parallel to the axis AA ′, and an intermediate section angled 56 connecting the sections 52, 54. The sections 52, 54 open upstream and downstream in the distributor / collector 36.

Dans l'exemple illustré par la figure 2, les tubes 51 du faisceau de tubes 32 définissent, en section dans un plan transversal à l'axe A-A', une enveloppe 55 de contour circulaire.In the example illustrated by figure 2 , the tubes 51 of the tube bundle 32 define, in section in a plane transverse to the axis AA ′, an envelope 55 of circular outline.

En variante, comme illustré par la figure 3 ou par la figure 5, les tubes 51 définissent, en section dans un plan transversal à l'axe A-A', une enveloppe 55 de contour allongé suivant un axe B-B' horizontal. Cette enveloppe est par exemple de forme sensiblement oblongue à bord droit (voir figure 3), ou de forme pseudo trapézoïdale, avec deux bords horizontaux parallèles raccordés par deux bords de contours en forme d'arc de cercle (voir figure 5).Alternatively, as illustrated by the figure 3 or by figure 5 , the tubes 51 define, in section in a plane transverse to the axis A-A ', an envelope 55 of elongated outline along a horizontal axis BB'. This envelope is for example of substantially oblong shape with a straight edge (see figure 3 ), or of pseudo-trapezoidal shape, with two parallel horizontal edges connected by two edges of contours in the shape of an arc of a circle (see figure 5 ).

Lorsque l'enveloppe définie par les tubes 51 est allongée, la compacité du dispositif d'échange thermique 10 est améliorée, pour une hauteur donnée séparant le faisceau de tubes 32 de l'organe de désengagement 44.When the envelope defined by the tubes 51 is elongated, the compactness of the heat exchange device 10 is improved, for a given height separating the bundle of tubes 32 from the disengagement member 44.

Le distributeur/collecteur 36 comporte un compartiment amont 60 de distribution du deuxième fluide sous forme gazeuse ou diphasique et un compartiment aval 62 de collecte du deuxième fluide sous forme liquide ou diphasique.The distributor / collector 36 includes an upstream compartment 60 for distributing the second fluid in gaseous or two-phase form and a downstream compartment 62 for collecting the second fluid in liquid or two-phase form.

Le compartiment amont 60 est raccordé d'une part à la source 14 de deuxième fluide, et d'autre part, aux tronçons amont 52 des tubes 51.The upstream compartment 60 is connected on the one hand to the source 14 of second fluid, and on the other hand, to the upstream sections 52 of the tubes 51.

Le compartiment aval 60 est raccordé d'une part, aux tronçons aval 54 des tubes 51 et d'autre part, à la capacité 16 de collecte du deuxième fluide sous forme liquide ou diphasique.The downstream compartment 60 is connected on the one hand, to the downstream sections 54 of the tubes 51 and on the other hand, to the capacity 16 for collecting the second fluid in liquid or two-phase form.

L'entrée inférieure 38 est piquée verticalement sous la calandre 30, et débouche vers le haut en regard du faisceau de tubes 32. Elle est propre à introduire le premier fluide sous forme liquide ou diphasique par débordement dans le volume intérieur 34. Elle est raccordée en amont à l'organe de détente 20, avantageusement à travers le séparateur liquide/gaz 22.The lower inlet 38 is stitched vertically under the grille 30, and opens upwards opposite the bundle of tubes 32. It is capable of introducing the first fluid in liquid or two-phase form by overflow into the interior volume 34. It is connected upstream of the expansion member 20, advantageously through the liquid / gas separator 22.

La paroi de rétention 50 présente une hauteur supérieure à la hauteur du faisceau de tubes 32. Elle est propre à retenir le premier fluide introduit par l'entrée inférieure 38 pour immerger sensiblement totalement le faisceau de tubes 32 dans le premier fluide.The retention wall 50 has a height greater than the height of the bundle of tubes 32. It is capable of retaining the first fluid introduced by the lower inlet 38 to immerse the bundle of tubes 32 substantially completely in the first fluid.

La sortie inférieure 40 est piquée verticalement sous la calandre 30, à l'opposé du faisceau de tubes 32 par rapport à la paroi de rétention 50.The lower outlet 40 is stitched vertically under the shell 30, opposite the bundle of tubes 32 with respect to the retention wall 50.

Le premier fluide liquide n'ayant pas été vaporisé dans le volume intérieur 34 est propre à s'écouler par débordement au-dessus de la paroi de rétention 50, et à s'évacuer à travers la sortie inférieure 40.The first liquid fluid which has not been vaporized in the internal volume 34 is able to flow by overflowing above the retention wall 50, and to be evacuated through the lower outlet 40.

La sortie supérieure 42 est piquée verticalement au-dessus de la calandre 30, de préférence en regard du faisceau de tubes 32, à l'opposé de l'organe de désengagement 44 par rapport au faisceau de tubes 32. Elle est raccordée en aval au compresseur 24.The upper outlet 42 is stitched vertically above the calender 30, preferably opposite the bundle of tubes 32, opposite the disengagement member 44 relative to the bundle of tubes 32. It is connected downstream to the compressor 24.

L'organe de désengagement 44 est destiné à éliminer les gouttelettes présentes dans le fluide entraîné au-dessus du faisceau de tubes.The disengagement member 44 is intended to eliminate the droplets present in the fluid entrained above the bundle of tubes.

Il est interposé horizontalement entre le faisceau de tubes 32 et la sortie supérieure 42, au-dessus du faisceau de tubes 32. Il s'étend avantageusement sur toute la longueur de la calandre 46.It is horizontally interposed between the bundle of tubes 32 and the upper outlet 42, above the bundle of tubes 32. It advantageously extends over the entire length of the calender 46.

Une hauteur minimale h1 est maintenue entre les tubes 51 du faisceau de tubes 32 et l'organe de désengagement 44. Cette hauteur est par exemple supérieure à 600 mm.A minimum height h1 is maintained between the tubes 51 of the bundle of tubes 32 and the disengagement member 44. This height is for example greater than 600 mm.

L'organe de désengagement 44 comporte au moins une cloison ajourée formée d'un treillis ayant une structure en caillebotis 70, telle qu'illustrée par la figure 7 ou d'un assemblage de lamelles parallèles 72, par exemple en forme de chevrons, telle qu'illustrées par la figure 8.The disengagement member 44 comprises at least one perforated partition formed by a trellis having a grating structure 70, as illustrated by the figure 7 or an assembly of parallel strips 72, for example in the form of rafters, as illustrated by the figure 8 .

La cloison ajourée définit un réseau d'alvéoles 74, permettant le passage du flux d'entraînement gazeux chargé de gouttelettes, et la collecte des gouttelettes à la périphérie des passagesThe perforated partition defines a network of cells 74, allowing the passage of the gaseous drive flow charged with droplets, and the collection of droplets at the periphery of the passages.

Dans l'exemple représenté sur la figure 2, l'organe de désengagement 44 comporte une première cloison longitudinale ajourée 80 située à une première hauteur, et une deuxième cloison longitudinale ajourée 82, disposée à l'écart verticalement de la première cloison longitudinale ajourée 80 à une deuxième hauteur au-dessus de la première hauteur.In the example shown in the figure 2 , the disengagement member 44 comprises a first perforated longitudinal partition 80 located at a first height, and a second perforated longitudinal partition 82, disposed vertically away from the first perforated longitudinal partition 80 at a second height above the first height.

L'organe de désengagement 44 comporte en outre une troisième cloison longitudinale ajourée 84 espacée horizontalement de la première cloison 80, à la même hauteur que la première cloison 80.The disengagement member 44 further comprises a third perforated longitudinal partition 84 spaced horizontally from the first partition 80, at the same height as the first partition 80.

Les cloisons longitudinales 80, 82, 84 sont formées par des plaques ajourées s'étendant horizontalement sur toute la longueur de la calandre 30.The longitudinal partitions 80, 82, 84 are formed by perforated plates extending horizontally over the entire length of the calender 30.

La première cloison 80 et la deuxième cloison 84 délimitent entre elles un espace intermédiaire 86 couvert vers le haut par la deuxième cloison 82.The first partition 80 and the second partition 84 delimit between them an intermediate space 86 covered upwards by the second partition 82.

La largeur de la deuxième cloison 82 est supérieure à celle de l'espace intermédiaire 86. Ainsi, au moins une partie latérale de la deuxième cloison 82 s'étend en regard de la première cloison 80, et au moins une partie latérale de la deuxième cloison 82 s'étend en regard de la troisième cloison 84.The width of the second partition 82 is greater than that of the intermediate space 86. Thus, at least one lateral part of the second partition 82 extends opposite the first partition 80, and at least one lateral part of the second partition 82 extends opposite the third partition 84.

La première cloison 80 est raccordée à la deuxième cloison 82 par une première paroi pleine inclinée 88. La troisième cloison 84 est raccordée à la deuxième cloison 82 par une deuxième paroi pleine inclinée 89.The first partition 80 is connected to the second partition 82 by a first inclined solid wall 88. The third partition 84 is connected to the second partition 82 by a second inclined solid wall 89.

Ainsi, selon l'invention, dans chaque plan transversal perpendiculaire à l'axe longitudinal A-A', l'organe de désengagement 44 comporte au moins deux régions 90, 92, 94 de passage de fluide disjointes, et au moins une région intermédiaire 98, 99 empêchant le passage de fluide.Thus, according to the invention, in each transverse plane perpendicular to the longitudinal axis A-A ', the disengagement member 44 comprises at least two regions 90, 92, 94 of disjointed fluid passage, and at least one intermediate region 98, 99 preventing the passage of fluid.

Dans l'exemple représenté sur la figure 2, au moins une première région 90 de passage de fluide est délimitée sur la première cloison ajourée 80, une deuxième région 92 de passage de fluide est délimitée sur la deuxième cloison ajourée 82, et une troisième région 94 de passage de fluide est délimitée sur la troisième cloison 84. La deuxième région de passage de fluide 92 est située au-dessus de la première région de passage de fluide 90 et de la troisième région de passage de fluide 94 en étant totalement disjointe de ces régions 90, 94.In the example shown in the figure 2 , at least a first region 90 of fluid passage is delimited on the first perforated partition 80, a second region 92 of fluid passage is delimited on the second perforated partition 82, and a third region 94 of fluid passage is delimited on the third partition 84. The second fluid passage region 92 is situated above the first fluid passage region 90 and the third fluid passage region 94 while being totally separated from these regions 90, 94.

Les régions intermédiaires 98, 99 empêchant le passage de fluide sont délimitées respectivement par les parois pleines 88, 89.The intermediate regions 98, 99 preventing the passage of fluid are delimited respectively by the solid walls 88, 89.

La deuxième région de passage de fluide 92 étant déportée verticalement par rapport aux régions de passage de fluide 90, 94, il est possible de remonter l'organe de désengagement 44 dans la calandre 30, sans diminuer la surface ajourée disponible pour le passage du flux entraîné.The second fluid passage region 92 being offset vertically relative to the fluid passage regions 90, 94, it is possible to reassemble the disengagement member 44 in the calender 30, without reducing the perforated surface available for the passage of the flow driven.

Le dispositif d'échange thermique 10 est donc plus compact, tout en conservant des propriétés adéquates d'élimination des gouttelettes présentes dans le flux entraîné.The heat exchange device 10 is therefore more compact, while retaining adequate properties for eliminating droplets present in the entrained flow.

Un procédé d'échange thermique, mis en oeuvre à l'aide du dispositif 10 selon l'invention, va maintenant être décrit.A heat exchange process, implemented using the device 10 according to the invention, will now be described.

Dans ce procédé, le deuxième fluide sous forme gazeuse est amené depuis la source 14 jusqu'au compartiment de distribution 60 du distributeur/collecteur 36. Le premier fluide est réparti entre les tubes 51 du faisceau de tubes 32 et circule successivement dans le tronçon amont 52, dans le tronçon intermédiaire coudé 56, puis dans le tronçon aval 54.In this process, the second fluid in gaseous form is brought from the source 14 to the distribution compartment 60 of the distributor / collector 36. The first fluid is distributed between the tubes 51 of the bundle of tubes 32 and flows successively in the upstream section 52, in the bent intermediate section 56, then in the downstream section 54.

Lors de ce passage dans le faisceau de tubes 32, le deuxième fluide se refroidit et se condense par échange thermique sans contact avec le premier fluide situé à l'extérieur des tubes 51 du faisceau 32 dans le volume intérieur 34.During this passage through the bundle of tubes 32, the second fluid cools and condenses by heat exchange without contact with the first fluid situated outside the tubes 51 of the bundle 32 in the interior volume 34.

Le deuxième fluide est collecté sous forme liquide dans le compartiment de collecte 62, puis est évacué hors du dispositif 10 jusqu'à la capacité 16.The second fluid is collected in liquid form in the collection compartment 62, then is discharged from the device 10 until the capacity 16.

Simultanément, du premier fluide sous forme liquide ou diphasique, obtenu par détente à travers l'organe de détente 20 est introduit en continu par l'entrée inférieure 38 dans le volume intérieur 34. Le premier fluide forme un bain de liquide, dans lequel sont immergés les tubes 51 du faisceau de tubes 32.Simultaneously, the first fluid in liquid or two-phase form, obtained by expansion through the expansion member 20 is introduced continuously through the lower inlet 38 in the internal volume 34. The first fluid forms a bath of liquid, in which the tubes 51 of the bundle of tubes 32 are immersed.

Les calories issues du deuxième fluide, collectées par le premier fluide provoquent l'évaporation partielle du premier fluide autour du faisceau de tubes 32 et le dégagement d'un flux entraîné au-dessus du faisceau de tubes 32.The calories from the second fluid, collected by the first fluid cause the first fluid to partially evaporate around the bundle of tubes 32 and the release of a flow entrained above the bundle of tubes 32.

Le flux entraîné est constitué majoritairement de gaz, mais comporte éventuellement des gouttelettes de liquide en amont de l'organe de désengagement 44.The entrained flow consists mainly of gas, but possibly includes droplets of liquid upstream of the disengagement member 44.

Lors du passage dans l'organe de désengagement 44, le flux entraîné traverse les régions de passage de fluide 90, 92, 94 des cloisons ajourées 80, 82, 84. Les gouttelettes de liquide sont retenues par la structure des cloisons 80, 82, 84, de sorte que le flux entraîné est totalement gazeux dans l'espace aval de récupération 100 situé à l'opposé du faisceau de tubes 32 par rapport à l'organe de désengagement 44.When passing through the disengagement member 44, the entrained flow passes through the fluid passage regions 90, 92, 94 of the perforated partitions 80, 82, 84. The liquid droplets are retained by the structure of the partitions 80, 82, 84, so that the entrained flow is completely gaseous in the downstream recovery space 100 situated opposite the bundle of tubes 32 relative to the disengagement member 44.

Le flux entraîné est ensuite extrait par la sortie supérieure 42 pour être amené jusqu'au compresseur 24.The entrained flow is then extracted through the upper outlet 42 to be brought to the compressor 24.

Dans le volume intérieur 34, l'excès de premier fluide non évaporé s'écoule par débordement à partir de la paroi de rétention 50 jusqu'à la sortie inférieure 40, avant d'être recyclé.In the internal volume 34, the excess of first non-evaporated fluid flows by overflow from the retention wall 50 to the lower outlet 40, before being recycled.

La présence d'un organe de désengagement 44 présentant des régions de passage de fluide disjointes améliore donc la compacité du dispositif d'échange thermique 10, sans nuire à la capacité d'élimination des gouttelettes de liquide dans le fluide entraîné, et en maintenant une distance suffisante entre le faisceau de tubes 32 et l'organe de désengagement 44.The presence of a disengagement member 44 having separate fluid passage regions therefore improves the compactness of the heat exchange device 10, without affecting the capacity for eliminating droplets of liquid in the entrained fluid, and maintaining a sufficient distance between the bundle of tubes 32 and the disengagement member 44.

Une variante de dispositif 10 non conforme à l'invention, représentée sur la figure 4, diffère du dispositif 10 représenté sur la figure 2 en ce que les cloisons longitudinales 80, 82 s'étendent verticalement, parallèlement l'une à l'autre sur toute la longueur de la calandre 30. La paroi pleine 88 s'étend horizontalement sous les cloisons 80, 82 pour obturer vers le bas l'espace aval 100.A variant of device 10 not in accordance with the invention, shown in the figure 4 , differs from the device 10 shown in the figure 2 in that the longitudinal partitions 80, 82 extend vertically, parallel to one another over the entire length of the calender 30. The solid wall 88 extends horizontally under the partitions 80, 82 to close down the downstream space 100.

La paroi pleine 88 fait saillie latéralement de part et d'autre des parois 80, 82, pour forcer le flux entraîné à se déplacer latéralement vers l'extérieur de la calandre 30, puis à effectuer un coude pour atteindre les cloisons ajourées 80, 82.The solid wall 88 projects laterally on either side of the walls 80, 82, to force the entrained flow to move laterally towards the outside of the grille 30, then to make an elbow to reach the perforated partitions 80, 82 .

Comme précédemment, les cloisons ajourées 80, 82 délimitent respectivement dans chaque plan transversal à l'axe A-A', une première région de passage de fluide 90 et une deuxième région de passage de fluide 92 disjointes. Les régions 90, 92 s'étendent ici verticalement.As previously, the perforated partitions 80, 82 respectively delimit in each plane transverse to the axis A-A ', a first region of fluid passage 90 and a second region of fluid passage 92 disjoint. The regions 90, 92 here extend vertically.

La première région de passage de fluide 90 et la deuxième région de passage de fluide 92 sont raccordées l'une à l'autre par une région pleine 98 horizontale, située en regard du faisceau de tubes 32.The first fluid passage region 90 and the second fluid passage region 92 are connected to each other by a solid horizontal region 98, located opposite the bundle of tubes 32.

Le fonctionnement du dispositif 10 représenté sur la figure 4 est analogue à celui du dispositif 10 représenté sur la figure 2.The operation of the device 10 shown in the figure 4 is similar to that of the device 10 shown in the figure 2 .

Une autre variante de dispositif 10 non conforme à l'invention est illustrée par les figures 5 et 6.Another variant of device 10 not in accordance with the invention is illustrated by the Figures 5 and 6 .

À la différence du dispositif 10 représenté sur la figure 1, le dispositif 10 représenté sur les figures 5 et 6 comporte une cheminée 110 faisant saillie verticalement au-dessus de la calandre 30.Unlike the device 10 shown in the figure 1 , the device 10 shown in the Figures 5 and 6 comprises a chimney 110 projecting vertically above the grille 30.

La cheminée 110 est de forme sensiblement cylindrique d'axe vertical C-C'. Elle débouche dans le volume intérieur 34, au-dessus du faisceau de tubes 32.The chimney 110 is of substantially cylindrical shape with a vertical axis C-C '. It opens into the interior volume 34, above the bundle of tubes 32.

La sortie supérieure 42 est ménagée à l'extrémité libre de la cheminée 110.The upper outlet 42 is formed at the free end of the chimney 110.

L'organe de désengagement 44 est contenu dans la cheminée 110.The disengagement member 44 is contained in the chimney 110.

Dans cet exemple, l'organe de désengagement 44 comporte une cloison ajourée 80 cylindrique d'axe vertical, de préférence coaxiale avec la cheminée 110. Il comporte une paroi pleine 88 fermant la cloison ajourée 80 vers le haut, et une paroi pleine annulaire 89 raccordant un bord inférieur de la cloison ajourée 80 à la périphérie de la cheminée 110.In this example, the disengagement member 44 comprises a perforated partition 80 cylindrical with a vertical axis, preferably coaxial with the chimney 110. It comprises a solid wall 88 closing the perforated partition 80 upwards, and a solid annular wall 89 connecting a lower edge of the perforated partition 80 to the periphery of the chimney 110.

La cloison ajourée cylindrique 80 débouche vers le bas en regard du faisceau de tubes 32, à l'intérieur de la paroi pleine annulaire 89.The cylindrical perforated partition 80 opens downward facing the bundle of tubes 32, inside the annular solid wall 89.

Comme précédemment, dans au moins un plan transversal perpendiculaire à l'axe A-A', visible sur la figure 5, la cloison ajourée 80 délimite une première région de passage de fluide 90 et une deuxième région de passage de fluide 92 disjointes. Les régions 90, 92 sont ici verticales.As before, in at least one transverse plane perpendicular to the axis AA ′, visible on the figure 5 , the perforated partition 80 delimits a first region of fluid passage 90 and a second region of fluid passage 92 separated. The regions 90, 92 are here vertical.

La paroi intermédiaire 88 délimite une région intermédiaire pleine 98 raccordant les régions 90, 92.The intermediate wall 88 delimits a solid intermediate region 98 connecting the regions 90, 92.

Par ailleurs, le faisceau de tubes 32 définit une enveloppe allongée horizontalement, ici de forme pseudo trapézoïdale.Furthermore, the bundle of tubes 32 defines a horizontally elongated envelope, here of pseudo-trapezoidal shape.

Dans une variante (non représentée) du dispositif 10 de la figure 3, l'organe de désengagement 44 comprend une unique cloison longitudinale ajourée 80 s'étendant horizontalement. L'organe de désengagement 44 ne comporte pas, dans au moins un plan perpendiculaire à l'axe longitudinal A-A', au moins deux régions de passage de fluide disjointes et au moins une région intermédiaire empêchant le passage de fluide.In a variant (not shown) of the device 10 of the figure 3 , the disengagement member 44 comprises a single perforated longitudinal partition 80 extending horizontally. The disengagement member 44 does not comprise, in at least one plane perpendicular to the longitudinal axis A-A ', at least two disjointed fluid passage regions and at least one intermediate region preventing the passage of fluid.

Dans une variante, illustrée par la figure 9, le faisceau de tubes 32 est un faisceau de tubes multicourants. Les tubes 51 d'une première région 200 du faisceau 32 sont raccordés à une source 202 de mélange réfrigérant. Les tubes 51 d'une deuxième région 204 sont raccordés à la source 14 de gaz naturel.In a variant, illustrated by the figure 9 , the bundle of tubes 32 is a bundle of multicurrent tubes. The tubes 51 of a first region 200 of the beam 32 are connected to a source 202 of refrigerant mixture. The tubes 51 of a second region 204 are connected to the source 14 of natural gas.

Dans cet exemple, les régions 200, 204 sont situées l'une au-dessus de l'autre.In this example, the regions 200, 204 are located one above the other.

En variante, représentée sur la figure 10, les régions 200, 204 sont situées côte à côte.Alternatively, shown in the figure 10 , regions 200, 204 are located side by side.

Dans le cinquième dispositif 10 selon l'invention, illustré sur la figure 11, les tubes 51 sont des tubes droits qui traversent la calandre 30 parallèlement à son axe A-A'.In the fifth device 10 according to the invention, illustrated on the figure 11 , the tubes 51 are straight tubes which pass through the calender 30 parallel to its axis AA ′.

Dans une variante, la cloison ajourée est formée d'une mousse métallique.In a variant, the perforated partition is formed from a metallic foam.

Dans une autre variante, la cloison ajourée comporte une paroi délimitant des ouvertures et une mousse métallique positionnée sur les ouvertures de la paroi.In another variant, the perforated partition comprises a wall delimiting openings and a metal foam positioned on the openings of the wall.

La mousse métallique est par exemple une mousse d'aluminium telle que la mousse Duocel® commercialisée par la société ERG Aerospace Corporation.The metallic foam is for example an aluminum foam such as the Duocel® foam sold by the company ERG Aerospace Corporation.

En outre, comme visible manifestement sur les figures, l'espace aval 100 de récupération de gaz, situé à l'opposé du volume intérieur par rapport à l'organe de désengagement 44 est délimité d'une part, par les régions de passage de fluide, et d'autre part, par la ou par chaque région empêchant le passage de fluide.In addition, as clearly visible in the figures, the downstream space 100 for recovering gas, located opposite the interior volume with respect to the disengagement member 44 is delimited on the one hand, by the regions of passage of fluid, and on the other hand, by or by each region preventing the passage of fluid.

Comme indiqué plus haut, cet espace aval 100 contient un fluide exclusivement gazeux ayant traversé les régions de passage de fluide.As indicated above, this downstream space 100 contains an exclusively gaseous fluid having passed through the fluid passage regions.
