Definitions

  • the present invention relates to a cryogenic distillation unit, in particular air distillation of the type comprising on the one hand a distillation apparatus comprising at least one cryogenic distillation column and at least one exchanger heat, and on the other hand means of thermal insulation of this device, the distillation device being arranged in a double-walled enclosure whose inter-wall contains a solid insulator.
  • a cryogenic distillation unit in particular air distillation of the type comprising on the one hand a distillation apparatus comprising at least one cryogenic distillation column and at least one exchanger heat, and on the other hand means of thermal insulation of this device, the distillation device being arranged in a double-walled enclosure whose inter-wall contains a solid insulator.
  • Such a unit is known from US-A-4 038 060. It applies for example to oxygen production units on board platforms oil at sea or on barges.
  • US-A-4038060 describes an apparatus for the cryogenic distillation of a radioactive gas which prevents dangerous leaks by surrounding the device with a filled double wall of perlite and using an adsorbent inside the inner shell to adsorb radioactive gases in the event of an accident.
  • cryogenic distillation columns and all associated equipment (heat exchangers, cryogenic pumps, cryogenic valves, connecting pipes, etc.) operating at low temperature are arranged in a "cold box", generally of rectangular shape, filled with loose insulation such as expanded perlite.
  • This insulation protects thermally each constituent both of the outside temperature and that of the other constituents having a different temperature.
  • This type of material holds its insulation qualities with both a low thermal conductivity ( ⁇ 0.05 w / m ° C) and a high pressure drop, favorable towards the convection phenomenon.
  • Offshore oil platforms produce waste gases. For some economic and environmental reasons, it becomes more and more necessary to recover these gases.
  • One method is to convert them to more hydrocarbons. heavy, in liquid form and therefore more easily transportable, by the process Fischer-Tropsch, which consumes large amounts of oxygen.
  • the invention therefore aims to provide a cryogenic distillation unit including effective protection against cryogenic fluid leakage.
  • the invention relates to a cryogenic distillation unit according to the claim 1.
  • the air distillation unit 1 shown in the Figures 1 and 2 essentially comprises an enclosure 2 to double wall in the interior space 3 of which are arranged a double air distillation column 4, heat exchangers 5, connecting pipes 6 and cryogenic accessories such as cryogenic pumps 7, cryogenic valves 8, etc.
  • Column 4 consists of two columns of distillation, medium pressure and low respectively pressure, as is well known in the art. These two columns 4A and 4B are arranged side by side, as shown see it in Figure 2, but they were brought back in the median plane in Figure 1 for clarity of the drawing. Of more, the distillation unit includes of course all the usual accessories and equipment.
  • Enclosure 2 has a double envelope.
  • the envelope interior 9 includes a flat bottom 10, a side wall cylindrical 11 and a domed roof 12, and is made of steel stainless.
  • the outer casing 13 includes a flat bottom 14, a cylindrical side wall 15 and a domed roof 16, and is made of carbon steel.
  • the bottom 14 can also be made of stainless steel.
  • the components arranged in space 3 are carried by feet 19 which cross with a watertight seal bottom 10 and rest on bottom 14.
  • the insulator 17 supports the inner envelope 9, but it is the bottom 14, and therefore the base 20, for example consisting of a frame steel, on which this base is placed, which support the weight of the components of the unit located inside enclosure 2.
  • this base 20 is fixed to the support structure 21, for example a metal bridge of oil or barge platform, through piles 22 which provide an air gap 23 between them.
  • An access chimney 24, closed by a plug removable 25, passes through the flysheet 12, 16 of the enclosure 2 and leads to components requiring maintenance, such as pumps 7 and valves 8.
  • Each component operating at a temperature different from that of column 4 is provided with insulation additional 26 in the form of swaddling with a glass wool or the like.
  • insulation additional 26 in the form of swaddling with a glass wool or the like.
  • a pipe 27 for supplying dry nitrogen gas to the room temperature, fitted with control valves 28, allows maintain space 3 and the inter-wall under a slight overpressure of the enclosure. This allows on the one hand to inert these volumes, and on the other hand to avoid in them the appearance condensation phenomena likely to put them in depression.
  • the roofs 12 and 16 are each equipped with a valve 29 of pressure limitation. Note that the cylindrical shape and dome of the enclosure promotes its resistance to overpressure.
