Definitions

  • the present invention relates to an installation for separating a gas mixture by distillation and, in particular, by cryogenic distillation.
  • cryogenic distillation installations a set of distillation columns is enclosed in a cold box in order to isolate it from the ambient heat.
  • the height of the cold box is generally determined by the height of the longest column.
  • argon of less than 1 ppm of oxygen by cryogenic way, it is necessary to install up to 250 trays in the argon column which makes the cold box very high and poses instability problems. It also contains a lot empty spaces which must be filled with insulating material.
  • DE-A-2633272 describes a double column with a low column pressure in two sections, the head of the two sections being at the same height.
  • the purpose of the present invention is to make the cold boxes more compact and reduce the empty spaces inside.
  • a separation installation of a gaseous mixture by distillation comprising at least two columns, the heads of two of the columns being at the same height, characterized in that minus two of the columns have the same height.
  • Figure 1 shows a double column 1 consisting of a column medium pressure 2 and a low pressure column 3, thermally connected by a reboiler-condenser.
  • An argon column in two sections 5A, 5B is supplied with a fluid enriched with argon from the lower column pressure.
  • the heads of the two sections of the argon 5 column and the column low pressure 3 are on the same level.
  • a liquid nitrogen storage 7 is located in the space below the argon column.
  • the cold box 9 contains the double column 1, the argon column 5 and the storage 7.
  • Figure 2 shows a double column 1, the lower column of which pressure is in two sections 3A, 3B.
  • the heads of the two sections 3A, 3B are at the same level.
  • the tank of second section 3B is supplied with overhead gas from the first section 3A and liquid is returned from the tank of the second section to the head of the first section.
  • the height of the second section 3B is identical to the total height of the first section 3A and the medium pressure column 2.
  • Figure 2 could obviously be adapted to include a argon column supplied by sections 3A, 3B of the low pressure column.
  • Figure 1 could include a storage of oxygen, nitrogen or argon below section 5A.
