Definitions
- the invention relates to an enclosure of a fluid catalytic cracking unit, in particular a regenerator chamber comprising an internal support device attached to the cyclones.
- the upper part contains cyclones for mechanical separation of particles suspended in a gaseous fluid, and possibly internal packing ("packing" in English) extending over the entire cross section of the chamber, and limiting the entrainment of catalytic particles, as described in WO2012022910.
- Such supports are generally attached to the side wall of the enclosure and must be able to be installed despite the congestion of the internal equipment of the enclosure, such as mechanical separation cyclones, possibly a central reactor, a gas pipe These supports are in fact most often attached to both the side wall of the enclosure and the internal equipment, usually cyclones.
- the invention aims to remedy all or part of these disadvantages by providing an enclosure of a catalytic cracking unit provided with a support device that is less sensitive to the phenomenon of differential expansion and can be installed despite reduced space available .
- a first object of the invention relates to an enclosure of a fluid catalytic cracking unit, a side wall defines an internal volume having a longitudinal axis extending in the direction of gravity or substantially in the direction of the gravity, said enclosure being provided with a plurality of mechanical separation cyclones located inside the internal volume, characterized in that it comprises, inside said internal volume, a support device secured only to the separation cyclones mechanical and comprising:
- peripheral support element extending along the side wall in a plane perpendicular to the longitudinal axis, remote from the lateral wall of a predetermined set in the plane of the support element, in particular a constant clearance
- a plurality of beams extending in the same plane as the peripheral support member, the beams being secured to the peripheral support member and at least one mechanical separation cyclone by an end or a remote attachment portion of its ends.
- the arrangement according to the invention thus makes it possible to produce a support device which is fixed solely to the mechanical separation cyclones. In other words, none of the beams is secured to the side wall of the enclosure. There is therefore no more differential expansion phenomenon between the support device and the wall of the enclosure on the one hand and between the support device and the cyclones on the other hand.
- the arrangement of the support device described allows its implementation despite the reduced available space left by the plurality of mechanical separation cyclones present in the enclosure.
- the peripheral support element may advantageously conform to the shape of the side wall of the enclosure, namely to follow the shape thereof, being separated therefrom from said predetermined clearance.
- an upper face of the support device defines a flat surface that can support robust way a grid disposed perpendicularly to the longitudinal axis of the enclosure.
- the peripheral support member extends away from the center of the enclosure. It can especially be annular.
- the beams can be secured to one or two mechanical separation cyclones, including adjacent cyclones, or even more cyclones.
- all the beams can be rectilinear.
- the support device may further comprise other beams extending in the same plane as the peripheral support member selected from one or more of the following beams:
- the support device may comprise several beams extending in the same plane as the peripheral support element and connecting other beams (including beams integral with one or more cyclones) while crossing each other, in particular at a single point, these beams being integral with each other at their point (s) crossing. This can facilitate the support of a grid by the support device and enhance the robustness of the support device.
- beams connecting other beams can meet - be integral - at a central point of the internal volume. This can make it possible to stiffen the structure of the support device.
- the support device may include a central support member extending proximate a central point of the internal volume, in the same plane as the peripheral support member.
- the support device may comprise beams extending in the same plane as the peripheral support element and each connecting one or two mechanical separation cyclones, in particular adjacent, to the central support element. This also makes it possible to obtain a robust structure of the support device. In this embodiment, some beams can also connect other beams together.
- the support device may comprise beams extending in the same plane as the peripheral support member and connecting one or two mechanical separation cyclones, in particular adjacent, to the central support member and to the peripheral support element.
- This embodiment is particularly advantageous when the enclosure has a tubular conduit located inside the enclosure and having a longitudinal axis parallel to the longitudinal axis of the inner side wall.
- the central support element can then be arranged around the tubular conduit and match the shape of this pipe being separated therefrom by a predetermined set, in particular constant, in the plane of the central support element.
- the central support member may then surround another internal equipment of the enclosure, such as a tubular reactor, a catalyst transfer line, a driving gas line or the like, without being in contact with it, from in order to avoid possible differential expansion phenomena.
- the enclosure according to the invention may furthermore comprise one or more of the characteristics mentioned below.
- At least a portion of the mechanical separation cyclones may have at least one support member shaped to support a beam end or a beam attachment portion.
- these support members may be shaped to receive and accommodate a beam end or a beam attachment portion.
- Beams may be attached to a mechanical separation cyclone at one of their ends, in particular such that a longitudinal direction of these beams passes through a central point of the separation cyclone, in the plane in which the beam extends. This can reduce the mechanical stress experienced by a cyclone supporting a beam.
- Beams may extend between two mechanical separation cyclones, in particular adjacent, and be attached to one or both mechanical separation cyclones. This can help to balance mechanical stresses experienced by a beam, especially when it is located between two cyclones, and to reinforce the robustness of the support device.
- the peripheral support member, and the central support member when present, may be formed of several portions defined in the plane of the support member by angular sectors whose center is a central point of the internal volume. . This may facilitate the installation of the peripheral support member, and any central support member, in the enclosure, in particular the relatively large peripheral support member. One end of a beam can then be attached to this support member between joined ends of two adjacent portions. This may make it easier to secure the beams to the support member.
- Each support member may have a spaced apart top wall and a bottom wall perpendicular to the longitudinal axis, between which a beam end is fixed or a beam attachment part.
- the beams can thus be maintained by means of a support member made in a simple manner.
- These spaced upper and lower walls can in particular be in the form of crowns, in the geometric sense of the term.
- Edges of the lower and upper walls of at least one support member may then be connected by a bottom wall to define a groove.
- the latter can then receive and house an end or a part of attachment of a beam.
- the support elements are made particularly simple and allow the beams to be effectively maintained.
- the peripheral support element and the central support element when present each define grooves open towards each other, which can in particular receive fixing walls for the beams.
- Each support element in particular peripheral, central or cyclone may have a plurality of fixing walls connecting the upper and lower walls, these fixing walls extending parallel to the longitudinal axis of the side wall of the enclosure.
- Each beam may then comprise at least one plane wall parallel to the longitudinal axis of the lateral wall, applied against a wall of fixing a support element, parallel to the latter and secured to the fixing wall.
- This attachment can be achieved simply by fasteners such as screw-nut assemblies, pins, rivets, etc., or by welding.
- the mechanical separation cyclones may be regularly distributed with respect to the longitudinal axis, in particular symmetrically. This allows a better distribution of mechanical stresses between the carrier cyclones of the support device.
- the beams can then also be arranged symmetrically with respect to the longitudinal axis.
- all the cyclones of the enclosure can support a beam.
- a grid may be placed on an upper face of said support device, matching the shape of the side wall, the mechanical separation cyclones and the cylindrical tubular conduit located inside the enclosure when it is present, being separated from these elements of a predetermined game, especially constant, in the plane of the support element.
- This grid can in particular support an internal lining. Such a grid does not undergo either differential expansion phenomena between the side wall and the internal (cyclones, .).
- the enclosure according to the invention may be an enclosure of a regenerator.

- FIG. 1 represents an enclosure 10 of a fluid catalytic cracking unit, here a regenerator enclosure.
- This chamber here of cylindrical shape, has a side wall 12.
- the invention is however not limited to an enclosure of particular shape.
- This lateral wall 12 delimits an internal volume 13 having a longitudinal axis X perpendicular to the plane of FIG. 1.
- the enclosure 10 is provided with a plurality of mechanical separation cyclones: a series of primary cyclones 14 and a series of secondary cyclones 16.
- Cyclones are used to separate the catalyst particles from the circulating gases in the unit. These are devices using centrifugal force to achieve a mechanical separation of particles suspended in a gas.
- the cyclones comprise an enclosure, generally substantially cylindro-conical, designed to impose a rapid rotation on the gas introduced into the body, for example by bringing the gas tangentially to the circumference of the enclosure, neighborhood of the wall. Under the effect of the centrifugal force, the solid particles taken in the vortex move towards the wall, lose their speed by friction and fall in the lower part of the apparatus, before exiting the apex of the cone.
- the gas follows the wall to the vicinity of the apex, and once cleared of particles, rises to the top to exit through a discharge pipe, which partially projects inside the enclosure.
- a cyclone usually includes:
- a separation chamber which generally comprises a cylindrical upper part and a conical lower part
- a third particle outlet pipe located in the lower part of the enclosure.
- the conical lower part 162 of the cyclone enclosure the conical lower part 162 of the cyclone enclosure, and a portion of the particle outlet duct 163.
- these cyclones 14, 16 are arranged vertically, their longitudinal axis extending substantially vertically.
- the cyclones 14, 16 are thus located inside the internal volume 13, substantially in the same horizontal plane perpendicular to the longitudinal axis X. They are here regularly distributed around the longitudinal axis X, the primary cyclones 14 being alternated With the secondary cyclones 16. In the example, four primary cyclones 14 and four secondary cyclones 16 are provided. The invention is however not limited to a particular number of cyclones, nor to a particular distribution thereof.

- This pipe 18 is here a cylindrical pipe of the same longitudinal axis X as the enclosure 10.
- the enclosure 10 has inside its volume 13 a support device 20, intended more particularly to support a grid and an internal lining.
- the support device 20 comprises:

- the beams extend radially.
- the invention is however not limited by a particular arrangement of the beams, provided that they are connected to a cyclone, and to another element of the support device, namely in this example the peripheral support element or the central support element.
- the support device is thus only fixed to the cyclones 14, 16 via the beams 206, 208, but is not fixed directly to the enclosure 10, in particular to its side wall 12.
- the elements of Peripheral and central support act as a frame for maintaining the beams and, despite the reduced available space left by the primary and secondary cyclones, the various elements of the support device 20 according to the invention can be easily set up.
- the peripheral support element 202 and the central support element 204 are respectively distant from the lateral wall 12 and the tubular reactor 18 by a predetermined clearance in the plane of these support elements.
- This clearance is preferably sufficiently small to prevent or limit the passage of the solid particles circulating inside the chamber, and advantageously high enough to accommodate the thermal expansion of the support device or possibly not to hang at an angle. . It may in particular be determined by those skilled in the art according to the characteristics of the solid particles and thermal expansion coefficients of the materials used.
- first beams 206 having a first end 206a attached to the peripheral support member 202 and a second end 206b attached to the central support member 204; these first beams also comprise one or two fixing portions 206c spaced apart from the first and second ends 206a, 206b respectively and fixed to one of the adjacent cyclones or to the two adjacent cyclones,
- second beams 208 having a first end 208a fixed to the central support member 204 or to the peripheral support member 202 and a second end 208b attached to a cyclone 14, 16, which may be a primary or secondary cyclone.
- the second beams 208 extending between a primary cyclone 14 and the peripheral support member 202 are relatively short relative to each other.
- the peripheral support element 202 is made of a number of portions 202i defined in the plane of the support elements by angular sectors of which the center is the center of the internal volume, located here on the longitudinal axis X. These portions are thus placed end to end and assembled by their ends.

- the various support members 202, 204, 210 are shaped to support either first or second beam ends, or a first beam attachment portion. To this end, they can be arranged to receive these ends or a fixing part, and have for example a complementary shape. It can thus be provided that the support members and the beam ends or beam attachment portions cooperate in a manner similar to male / female elements.
- each support member has a spaced apart upper and lower wall perpendicular to the longitudinal axis X of the side wall 12.
- the peripheral and central support members 202 thus each comprise an upper wall 212, 212 'and a bottom wall 214, 214' respectively (see FIGS. 3-5). These walls are connected by a bottom wall 216, 216 'respectively along one of their edge.
- the bottom wall extends on the side of the side wall 12, so that the upper 212, lower 214 and bottom 216 walls define a groove (see Figure 5) whose opening is directed towards the longitudinal axis X.
- the bottom wall 216 ' is located on the side of the tubular reactor 18, namely on the longitudinal axis X side, so that the opening of the groove is directed towards the side wall 12. The two grooves are thus open towards one another.

- Each support member 202, 204, 210 further has attachment walls 218 that extend perpendicularly to the upper and lower walls and join them. These fastening walls 218 extend parallel to the longitudinal axis X. They can thus bear in abutment solid flat walls of the beams also extending parallel to the longitudinal axis X. Fasteners of the rivet type, which are bolt or others can be used for fastening.
- the mechanical separation cyclones 14, 16 here also present symmetrical enclosures of revolution.
- the fixing walls 218 of the support members 210 preferably extend radially with respect to the axis of revolution of the cyclone to which they are attached, for a better resistance to mechanical stresses.
