  • the present invention relates to air distillation installations.
  • the object of the invention is to provide a flexible solution which can be used for practically all air distillation installations, up to large sizes.
  • Each framework can in particular group together all of the control, command and instrumentation organs in a lateral housing located at its lower part, the two housings facing each other and framing a work station for an operator.
  • the framework can in particular group together all of the control, command and instrumentation bodies in a lateral housing located at its lower part.
  • the installation shown in Figure 1 includes an air compression module or group 1, two air cleaning bottles (desiccation-decarbonation) by adsorption 2A, 2B with alternating operation, a "hot” module 3, a "cold” module 4, a double distillation column 5, and a set of straight connecting pipes 6.
  • the module 1 comprises, on a base 7, an electric motor 8 driving a main compressor 9, and the intermediate refrigerants 10 of the compressor.
  • the discharge of the latter leads to a connector 11 for output of the module 1.
  • the bottles 2A, 2B are bottles conventional adsorption, each provided with two connections, respectively 12A, 12B.
  • the module 3 comprises a parallelepipedic frame 13 in which are fixed all the "hot" elements of the installation other than the compression module and the purification bottles: the final refrigerant 14 of the compressor, connected to a connection of inlet 15 disposed opposite the connector 11, and a refrigeration unit 17 mounted in series with the coolant 14, a heater 18 for adsorbent regeneration gas, the pipe 19 for evacuating the residual gas from the column, provided with a silencer 20, and also all the control, command and instrumentation members relating to the elements 14 to 20, shown diagrammatically at 21.
  • the module 3 also has two connections 22A, 22B for each bottle 2A, 2B respectively, and connections 23 for connection with the cold module 4, three in number in this example.
  • the module 4 comprises the main heat exchange line 24, consisting of several bodies of parallelelipedic exchangers of the brazed plate type, a sub-cooler 25, the cold accessories of the installation such as cryogenic pumps 26 and turbines 27 , and all of the control, command and instrumentation members relating to elements 24 to 27, shown diagrammatically at 28.
  • the module 4 also includes fittings 29 for input / output of the heat exchange line, in number equal to the connections 23 and arranged opposite them, and of the connections 30 for connection to the column 5. All of the elements 24 to 30 are mounted in a parallelepiped frame 31. All of the cold parts of the cold elements ( exchangers 24 and 25, cryogenic valve bodies, pumps 26, turbines 27, etc.) are thermally insulated, for example by means of perlite.
  • modules 3 and 4 may vary in type and number.
  • these modules include all the connecting pipes from their elements to each other, with the corresponding automatic and / or remote-controlled valves.
  • Column 5 is a double column comprising a medium pressure column surmounted by a low pressure column, with a main vaporizer-condenser which brings the overhead vapor (nitrogen) of the medium pressure column into contact with heat exchange liquid.
  • low pressure column tank (oxygen) This double column, the height of which is considerably greater than that of the modules 3 and 4, is vacuum-insulated by a cylindrical wall 32 from which emerge fittings 33 equal in number to the fittings 30 and arranged opposite them.
  • modules 3 and 4 of generally parallelepiped shape whose external dimensions allow road transport.
  • modules 3 and 4 are combined into a single module 103 transportable by road, this module containing all the necessary elements during operation of the installation, mounted in a parallelepipedic frame 113 equipped with all fittings 15, 22A, 22B and 30, all of the control, command and instrumentation members being assembled on one side of the module, at 121.
  • the assembly on site is then even simpler than in the case of Figure 1.
  • the or each module 3, 4 or 103 may have on one side, in its lower part, a compartment 34 very easy to access where are grouped together all the control, command and control elements. instrumentation 21, 28 or 121.
  • the heat exchange line 24 may partly overhang the sub-cooler 25 and partly the compartment 34.
  • the assemblies 21 and 28 can be placed in facing compartments open towards one another, and provide between them, between the modules 3 and 4, a work station 35 having direct access to all the control, command and instrumentation bodies of the installation.
  • the installation also includes the various usual equipment linked to the supply of electric current, cooling water and possibly auxiliary gas, this equipment being connected to the corresponding components of the modules described above.
