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.
  • the invention also relates to an installation for liquefying hydrocarbons, comprising at least one liquefaction train, the liquefaction train comprising a device as described above.
  • the disengagement member does not necessarily include in at least one plane perpendicular to the longitudinal axis, at least two regions of disjoint fluid passage and at least one intermediate region preventing the passage of fluid.
  • upstream and downstream are understood with respect to the normal direction of circulation of a fluid in the heat exchange device.
  • 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.
  • 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.
  • the first fluid is a hydrocarbon, for example propane, or a mixture of hydrocarbons.
  • 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.
  • 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.
  • the installation 12 further comprises a refrigeration cycle 18, in which the first fluid circulates.
  • 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.
  • the heat exchange device 10 is of the shell and tube bundle type.
  • the bundle of tubes is represented schematically by a single tube on the figure 1 .
  • 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.
  • 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.
  • the calender 30 extends along a longitudinal axis AA ′ of elongation, which in the example shown in the figure 1 , is a horizontal axis.
  • 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.
  • the bundle of tubes 51 comprises for example more than 5000 tubes.
  • 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.
  • 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.
  • 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.
  • 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 ).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the lower outlet 40 is stitched vertically under the shell 30, opposite the bundle of tubes 32 with respect to the retention wall 50.
  • 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.
  • 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.
  • the disengagement member 44 is intended to eliminate the droplets present in the fluid entrained above the bundle of tubes.
  • 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.
  • 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 .
  • the 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.
  • 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.
  • 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.
  • the longitudinal partitions 80, 82, 84 are formed by perforated plates extending horizontally over the entire length of the calender 30.
  • the first partition 80 and the second partition 84 delimit between them an intermediate space 86 covered upwards by the second partition 82.
  • the width of the second partition 82 is greater than that of the intermediate space 86.
  • 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.
  • 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.
  • the disengagement member 44 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.
  • first region 90 of fluid passage is delimited on the first perforated partition 80
  • second region 92 of fluid passage is delimited on the second perforated partition 82
  • 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.
  • the intermediate regions 98, 99 preventing the passage of fluid are delimited respectively by the solid walls 88, 89.
  • 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.
  • the heat exchange device 10 is therefore more compact, while retaining adequate properties for eliminating droplets present in the entrained flow.
  • 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.

  • 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.
  • 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.
  • the entrained flow consists mainly of gas, but possibly includes droplets of liquid upstream of 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.
  • the entrained flow is then extracted through the upper outlet 42 to be brought to the compressor 24.
  • the excess of first non-evaporated fluid flows by overflow from the retention wall 50 to the lower outlet 40, before being recycled.
  • 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.
  • 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.
