Definitions

  • the invention relates to a plant for gas separation according to claim 1. Particularly preferred embodiments are described in the subclaims.
  • Both mounting variants described in the prior art have the disadvantage that the enclosure must be built under an unnecessarily high material consumption with very high mechanical stability.
  • the entire combination of separation column and enclosure is brought into the vertical position.
  • the enclosure and its connection to the separation column must be made so stable that they can absorb the entire weight of the separation column during the erection process.
  • This stability requirement is well above the stability requirements for later operation of the plant.
  • the envelope is used for thermal insulation and therefore only has to absorb the wind loads. Due to the unnecessarily high stability during the erection process, the consumption of material for the envelope is therefore significantly higher than would be required for stationary operation.
  • the different temperatures must be taken into account when installing and constructing such systems.
  • the assembly takes place in the warm state (ambient temperature) while gas separation during the actual operation of the system, eg. As in a plant for air separation, prevail in some parts of the plant cryogenic temperatures (60-80 K), while other parts are much warmer.
  • the prevailing different temperatures result in different material expansions, which come into play in particular with accessories such as piping, instruments, inlets and outlets and / or fittings.
  • These different temperature expansions must be taken into account in design and assembly, especially with regard to the positioning of the parts. This increases especially the design effort in externally accessible parts considerably.
  • the present invention is therefore based on the object, a method for assembling a system for gas separation in such a way that a simple installation on site while minimizing the design effort and the material cost of the enclosure over the prior art is guaranteed.
  • the present object is achieved by a gas separation plant according to claim 1 of the application.
  • the basic idea of the invention is to transport the prefabricated column to the construction site and at least partially carry out the assembly of accessories, such as, for example, pipelines, inlets and outlets, fittings, valve seats and / or instruments.
  • the installation of the accessories is carried out according to the invention on the upper half of the lateral surface facing away from the bottom of the separation column.
  • the accessories are attached to pipe bridge modules, which consist of a cuboid, cylindrical or oval cylindrical frame.
  • the assembly of the pipe bridge modules, as well as the assembly of the attached accessories, can take place wholly or partly in the workshop or directly on site at the construction site.
  • the mounting of the accessories allows a horizontal position of the separation column almost at ground level.
  • the separation column must only be scaffolded at the height of its diameter.
  • Parallel to this, at least partial prefabrication of the wrapper is in its vertical orientation, leaving the upper side of the wrapper open.
  • the pre-assembled separation column can then be erected in its vertical orientation and lifted through the upper, open side into the enclosure. Subsequently, the remaining accessories, if not previously mounted, attached, the envelope completed and closed.
  • the prefabrication of the side surfaces of the envelope takes place before the introduction of the separation column to a height of one third of the total height, more preferably up to half the total height.
  • the pressure test and / or quality inspection of the separation column and / or the X-ray inspection of the welds in the horizontal orientation of the separation column before erecting done.
  • all essential and to be tested parts are easily accessible, so that the test can be done with little effort.
  • This axis is located in the assembly method according to the invention on the upper half of the lateral surface in horizontal storage.
  • the positioning of the pipe bridge modules along a single axis further simplifies the design of the plant.
  • the pipe bridge modules specify the position of all accessories.
  • the attachment of the pipe bridge modules along an axis allows mounting in the horizontal orientation of the separation column before the erection in the vertical end position.
  • the linkage of the frame, which make up the pipe bridge modules made of chrome-nickel steel.
  • the design proves to be cube-shaped frame.
  • a foreclosure is attached to the pipe bridge modules, wherein the foreclosure surrounds flanged components and / or instruments, which are accessible from outside the enclosure, and wherein the foreclosure a volume to the components and / or instruments forms, which is not filled with insulating material (perlite).
  • the partition is an arbitrary hollow body around the flanged accessories, which is suitable to form a volume around the flanged accessories, which is not filled with insulating material (perlite) in the space between the enclosure and separation column.
  • insulating material perlite
  • This partition can be advantageously attached to the pipe bridge modules. By the partition, a cavity is formed around the flanged accessories, which also represents a cavity insulation.
  • the foreclosure is expediently filled in rigid areas, preferably about 400 mm, behind the gas-tight access in the enclosure (for example, a manhole) with glass wool.
  • the separation column is formed by an air separation column.
  • This may, for example, be a double air separation unit having a pressure column, a low pressure column and a main condenser.
  • the casing is the wall of a coldbox whose voids are filled with insulating powder (Perlite) before the system is put into operation.
  • FIG. 1 shows a separation column (1) with pipe bridge modules (2a-2d), which is installed according to the assembly method according to the invention in a gas separation plant.
  • the separation column (1) is prefabricated in a workshop and equipped with pipe bridge modules (2a-d).
  • the separation column (1) is stored horizontally, so that the tube bridge modules (2a-d) along an axis parallel to the preferred axis of the separation column (1) on the upper half of the shell.
  • the installation of the pipe bridge modules (2a-d) can be done wholly or partly in the factory or on the construction site.
  • the assembly of the accessories is carried out at least partially with horizontal storage of the separation column (1) to the pipe bridge modules (2a-d).
