  • the present invention relates to a frame panel intended to form part of a cold box of a separation apparatus and to a cold box comprising such a panel.
  • the units for separation by distillation at low temperature, or even cryogenic temperature comprise at least one distillation column which is arranged in an insulating structure called a cold box (BF).
  • the cold box is a metal enclosure generally having a substantially parallelepipedal shape so as to provide around the column and its pipes a predetermined insulation thickness.
  • the insulation used is generally perlite.
  • a low temperature is a temperature below 0 ° C, or even below -100 ° C.
  • the present invention deals with boxes internal to a LF, housing at least one accessory chosen from the following group: manual valve, automatic valve, flowmeter, valve, sensor or other instrumentation means.
  • the accessory generally requires access for maintenance operations but is connected to the piping of the distillation columns and / or the heat exchangers of a device for separation by distillation at low temperature, or even cryogenic temperature.
  • the mixtures to be separated include air or air gases for the ASUs (double main column or argon column) but also a synthesis gas comprising hydrogen and carbon monoxide, an ammonia synthesis gas comprising nitrogen and hydrogen, a mixture comprising carbon dioxide, oxygen and nitrogen or a mixture comprising carbon dioxide and hydrogen.
  • the cold boxes can be assembled on site or prefabricated in the workshop.
  • one of the methods commonly used is to pre-assemble the column with piping elements and accessories in a manufacturer's workshop and insert it into a metal enclosure, with a section integrating the future insulation thicknesses all around the column as described in EP 0 913653 A1 .
  • This assembly, pre-assembled in a horizontal position, called a package unit or in English “package unit” is then transported and installed on the final construction site.
  • At least one accessory of the BF chosen from the following group: valve manual, automatic valve, flowmeter, valve, sensor or other means of instrumentation etc ... requiring its installation in an independent box fixed on the internal walls of the BF, is installed in an accessory box, of parallelepiped shape but with roof and / or bottom faces inclined between 45 ° and 60 ° horizontally in order to avoid the perlite sloping and loss of insulation performance.
  • the caisson itself is installed in the package in order to allow it to be thermally insulated, generally with rock wool, once the installation on the construction site is completed and before the start of the BF which itself is filled with a powdery perlite type insulation.
  • the entire assembly of the BFs is carried out on the construction site. That is to say that all the pipes of the BF must be installed one by one and connected to the vertical distillation column or / and to other columns, to / cryogenic exchangers or / and to pumps or / and turbines at a height ranging from the ground to about 60m.
  • the accessories manual or automatic valves, flowmeters, valves, various sensors etc.
  • These accessory boxes can be located on any internal face of the BF at a height varying between the ground and approximately 60 m. These boxes are of the same type as those installed in the packages and house the accessories seen previously.
  • one of the challenges is to significantly reduce the installation time and planning risks of the BF by limiting construction activities as much as possible while ensuring a level of quality comparable to the manufacture of packages unites in workshop.
  • the present invention proposes, on the one hand, to design a box housing the various accessories (manual or automatic valves, flow meters, valves, various sensors, etc.) and to have it manufactured in a unit. builder's workshop.
  • the distillation column can be partially equipped, in the manufacturer's workshop, with some of its pipes, such as obviously those which will have to be connected. to the accessory boxes so as to completely reconstitute the piping network once the accessories box is attached to its structural panel in place and after welding of the pipe interfaces of said box with the pipe sections previously installed on the distillation column.
  • This casing will then be shipped, like the distillation column fitted with some of its pipe sections, to the construction site.
  • This box will have at least one open face which will subsequently be in contact with the frame panel of the BF.
  • This box the structure of which will be in carbon or stainless steel, will preferably be provided with handling means (in English “lifting lugs") in order to handle it in order to connect it by welding or by bolting to the inside face of a frame panel.
  • handling means in English "lifting lugs"
  • connection of the box to the frame panel should preferably be on the ground, at human height or else requiring only a small mobile scaffolding, before lifting and final installation of the frame panel around the distillation column in order to minimize the risks and reduce the generally very expensive work at height.
  • the object of the present invention is to provide an assembly means making it possible both to maintain the quality criteria of pre-assembly in the workshop of elements requiring high quality control (typically the entire cryogenic part), while greatly limiting the problems and transport costs to the construction site and facilitate their installation on the construction site of the Cold Boxes mounted on site.
  • a frame panel intended to form part of a cold box of a separation apparatus by distillation at a low temperature
  • at least one casing made of carbon steel or of stainless steel for example. example comprising chrome and nickel, with rectangular or non-rectangle trapezoidal section, possibly isosceles, having a roof and / or a bottom inclined at an angle of between 45 ° to 60 ° with respect to the panel and an open face, the open face being positioned on the interior face of the framing panel.
  • a cold box of a separation apparatus by distillation at a low temperature comprising at least four vertical walls, at least one of which is constituted by or comprises a panel as described above. above, the cold box being filled with insulation and containing at least one element of the apparatus intended to operate at a low temperature, or even at a cryogenic temperature.
  • the cold box preferably contains at least one distillation column and / or at least one heat exchanger.
  • a method of mounting a box cold of a separation apparatus by distillation at a low temperature comprising at least four panels to be arranged vertically around an element intended to operate at a low temperature, or even at a cryogenic temperature, in which the wall is fitted with at least one panel of a box of carbon steel or chromium and nickel alloy with rectangular or non-rectangle trapezoidal section, possibly isosceles, having a roof and / or a bottom inclined at an entrance angle 45 ° to 60 ° to the panel and an open face, fixing the open face to the interior face of the frame panel.
  • the box can be fixed to the panel in a workshop or at the site of installation and / or construction of the cold box.
  • the panels are fixed together once the box is attached to the panel.
  • a panel 5 of a cold box of a distillation air separation apparatus is shown; the cold box may contain a column and / or a heat exchanger.
  • An element 3 to be insulated is illustrated as being surrounded by perlite 15.
  • Attached to the interior face of the panel 5 is a casing 1 made of carbon steel or chromium and nickel alloy (stainless steel). It has a roof at an angle of 60 ° relative to a vertical plane, which is that of panel 5. The bottom is inclined at 45 ° relative to the panel. Other angles between 45 ° and 60 ° are possible.
  • the box 1 has an open face, the open face being positioned on the interior face of the frame panel 5.
  • Inside the box 1 is at least one accessory 9 which can be a manual valve, an automatic valve, a flowmeter, a valve or a sensor.
  • the accessory is connected, if necessary, to the outside of the cold box through the panel 5 and a sleeve 8 to its actuator 10.
  • the box section is trapezoidal. In the figure, it is a non-rectangle and non-isosceles trapezoid, since the roof is tilted at 60 ° vertically and the bottom is tilted 45 ° vertically. It is also possible that the two angles are the same. Otherwise the roof and / or the bottom may be perpendicular to the panel, in which case the section is in the shape of a rectangular trapezoid.
  • At least one wall of the box 1 may be perforated, for example by being made of mesh or of expanded metal 18.
  • the mesh is covered with a material impermeable to a particulate insulator, the box of which is filled, for example with perlite 15 but permeable to sweep gas. This allows the purge gas, eg nitrogen, which circulates in the perlite 15 to circulate in the chamber to prevent the formation of ice packs or the accumulation of other impurities.
  • a distillation column 3 is placed in a cold box consisting of eight angle panels 5.5A having an L-shaped section. Only four of the panels are visible in the figure.
  • the panels 5.5A each have a box 1 fixed to the inner wall. Obviously the panels of the cold box do not necessarily carry a box. This is again a case in carbon steel or chrome and nickel alloy (stainless steel). It has a roof at an angle of 60 ° relative to a vertical plane, which is that of panel 5. The bottom is inclined at 45 ° relative to the panel.
  • the box or boxes contain rock wool and the cold box is filled with perlite in use.
  • Column 3 is lined with pipes and can be connected to an accessory present in one of the boxes.
  • the boxes 1 can be fixed to the 5.5A panels by welding or bolting. It is preferable to fix the box to the panel 5A on the ground and then to lift the panel 5A into position above the panel 5. However, it is possible to put the box in place subsequently on its frame panel after lifting said panel by a opening in the roof of the BF or sliding it from the outside through one face of a framing panel using the walkways of the BF.
  • the figure 2 shows that the boxes are in place before attaching the cold box panels together.
  • the figure 3 shows the detail of the box 1 with its accessories such as manual valve, automatic valve, flowmeter, valve, sensor as well as at least one pipe section 23 connected to the accessory.
  • accessories such as manual valve, automatic valve, flowmeter, valve, sensor as well as at least one pipe section 23 connected to the accessory.
  • the actuator 10 of the valve 9 protruding to the outside and wire 21 for connecting instrumentation in the future.
