Structural panel intended to form part of a cold box of a separation device

Abstract

Structural panel intended to form part of a cold box of a low-temperature distillation separation device, comprising at least one chamber made from carbon steel or chrome and nickel alloy steel, with a rectangular or non-rectangular, optionally isosceles, trapezoid cross-section, having a roof and/or bottom sloping at an angle of between 45° and 60° relative to the panel and one open face, the open face being positioned on the inner face of the structural panel.

1 . A structural panel configured to form part of a cold box of a low-temperature distillation separation device, comprising at least one chamber made from carbon steel or stainless steel, the panel having a cross-section, having a roof and/or bottom sloping at an angle of between 45° and 60° relative to the panel and one open face, the open face being positioned on the inner face of the structural panel. 
     
     
         2 . The panel according to  claim 1 , containing at least one accessory selected from the group consisting of a manual valve, an automatic valve, a flow meter, a valve shutter or other instrumentation means, a pipe spool connected to the accessory, and combinations thereof. 
     
     
         3 . The panel according to  claim 1 , in which the chamber comprises at least one means for handling the chamber and at least one permanent or temporary support to support the at least one pipe spool and/or the at least one accessory during the transport phases and the connection to the structural panel. 
     
     
         4 . The panel according to  claim 1 , in which the chamber is fastened to the panel by welding or bolting, preferably on the ground before lifting. 
     
     
         5 . The panel according to  claim 1 , in which the chamber comprises at least one perforated face covered with a material that is impermeable to a particular insulation material, for example to perlite, but permeable to a flushing gas. 
     
     
         6 . The panel according to  claim 1 , in which the chamber contains rock wool and/or aerogel. 
     
     
         7 . The panel according to  claim 1 , wherein the cross-section is selected from the group consisting of rectangular, non-rectangular, isosceles, and trapezoidal. 
     
     
         8 . A cold box of a low-temperature distillation separation device, comprising at least four vertical walls, at least one of which comprises the panel according to  claim 1 , the cold box being filled with an insulation material and containing at least one element of the device configured to operate at a low temperature or at a cryogenic temperature. 
     
     
         9 . The cold box according to  claim 8 , further comprising at least one distillation column and/or at least one heat exchanger. 
     
     
         10 . A method for assembling a cold box of a low-temperature distillation separation device, comprising at least four panels to be arranged vertically around one element configured to operate at a low temperature or at a cryogenic temperature, wherein the wall of at least one panel is provided with a chamber made from carbon steel or chrome and nickel alloy steel, having a roof and/or bottom sloping at an angle of between 45° and 60° relative to the panel and one open face, by fastening the open face to the inner face of the panel. 
     
     
         11 . The method according to  claim 9 , wherein the chamber is fastened to the panel in a workshop. 
     
     
         12 . The method according to  claim 9 , wherein the chamber is fastened to the panel on the installation site of the cold box. 
     
     
         13 . The method according to  claim 9 , wherein the chamber is fastened to the panel on the construction site of the cold box. 
     
     
         14 . The method according to  claim 9 , wherein the panels are fastened together once the chamber is fastened to the panel. 
     
     
         15 . The method according to  claim 9 , wherein the cross-section is selected from the group consisting of rectangular, non-rectangular, isosceles, and trapezoidal.
