Definitions

  • the present invention relates to an apparatus and a method for separating air by cryogenic distillation.
  • the first arrangement makes it possible to obtain improved energy performance as it saves loss of pressure in the gas return pipes (predominant effect) and energy from the liquid return pumps.
  • the difference in pressure between the average pressure column and the low pressure column is typically less than 2 bar absolute pressure, which necessitates the installation of a pump for raising liquid in the case where sections of the low pressure column are installed above the average pressure column.
  • an apparatus for separating air comprising a first distillation column capable of operating at an average pressure, a second distillation column capable of operating at a low pressure, a third distillation column capable of operating at a low pressure or at the low pressure, a first condenser-vaporizer, a second condenser-vaporizer arranged in the bottom of the second column, a pipe for supplying air at least to the first column, a pipe for supplying a nitrogen-enriched liquid from the head of the first column to the head of the third column, at least one pipe for supplying liquid from the bottom of the third column to the first condenser-vaporizer, a pipe for supplying a liquid from the bottom of the first column to the third column, a pipe for supplying liquid from the first condenser-vaporizer to the second column, a pipe for supplying overhead gas from the second column to the bottom of the third column, the first, second and third columns being arranged side-by-side, possibly all being arranged on a floor surface
  • the second column contains at least a third condenser-vaporizer placed above the second condenser-vaporizer.
  • An apparatus element for example a liquid oxygen vaporizer, capable of operating at a cryogenic temperature, may be arranged below one of the columns and wherein the two other columns and the element are placed directly on the floor surface.
  • Pressurization means may be connected to the bottom of the second column and to the liquid oxygen vaporizer.
  • the first condenser-vaporizer may be above the first column and connected to the head of the first column to permit reboiling by a gas from the first column.
  • the apparatus comprises just one pump connected to two of the columns.
  • the pump may be connected to the two pipes for supplying liquid from the bottom of the second column to the first condenser-reboiler.
  • a gas pipe may connect the first condenser to the bottom of the third column.
  • the head of the second column and/or the third column may be at a lower level than the first condenser-reboiler and preferably lower than the head of the first column.
  • the packing densities in the first column may be lower than the packing densities of the second column and/or of the third column.
  • the third column does not contain a condenser-reboiler.
  • the second column may also contain a third condenser-reboiler in addition to means for exchanging heat and material arranged above the third condenser-reboiler.
  • the pipe for supplying overhead gas from the second column to the bottom of the third column may be connected to a pipe for gas vaporized in the first condenser-reboiler.
  • the apparatus element is preferably a liquid oxygen vaporizer, arranged below the third column.
  • the difference in pressure between the operating pressure of the first column and the pressure of at least one of the second and third columns is preferably less than 3 bar, preferably 2.5 bar, preferably 2 bar.
  • the difference in pressure between the operating pressure of the top of the second column and the bottom of the third column may be less than 1 bar, preferably less than 0.5 bar, preferably less than 0.2 bar.
  • the apparatus comprises a first column 1 operating at an average pressure, a second column 2 operating at a low pressure and a third column 3 operating at a low pressure which is slightly less than that of the second column 2 , the low pressure columns preferably operating at a difference in pressure of less than 500 mbar (and preferably 200 mbar) measured between the bottom of the column 3 and the top of the column 2 .
  • the difference in pressure between the average pressure column 1 and the low pressure column 2 or 3 , measured in the middle of each column is less than 3 bar, preferably 2.5 bar, preferably 2 bar.
  • the three columns 1 , 2 , 3 are placed on the floor surface 27 , but the third column 3 is raised as a product vaporizer 11 is placed below said column. It is naturally possible to place the vaporizer 11 elsewhere and to place the column 3 directly on the floor surface 27 .
  • the floor surface 27 consists of a concrete base or other planar surface.
  • a compressed air flow 33 which is purified and cooled is passed into the bottom of the first column 1 where it is separated, forming an oxygen-enriched flow 25 and a nitrogen-enriched flow.
  • the oxygen-enriched flow 25 is passed to a lower level of the third column 3 .
  • the nitrogen-enriched flow condenses in the overhead condenser 9 of the first column.
  • Said condenser 9 is cooled by a flow of liquid 23 pumped from the bottom of the third column 3 and pressurized by a pump 13 which is also placed on the floor surface 27 .
  • the vaporized liquid 17 from the condenser 9 is mixed with an overhead gas 15 of the second column 2 to form a gaseous flow 19 which supplies the bottom of the third column 3 .
  • the head of the column of the second column 2 is supplied by a liquid 21 from the condenser 9 .
  • the second column 2 contains one or two, or more, reboilers, including a bottom reboiler 5 and possibly an intermediate reboiler 7 .
  • Said reboilers may be heated up by any suitable means, including an air flow, whether cold compressed or not, or a nitrogen flow, whether cold compressed or not.
  • a flow of gaseous or liquid oxygen 29 is withdrawn at a low level of the second column 2 .
  • Said flow of liquid may be pressurized by a pump (not shown) and passed to the vaporizer 11 to form a pressurized gaseous flow.
  • a liquid nitrogen flow 35 is expanded in a valve and passed to the head of the third column 3 and a nitrogen-enriched gaseous flow 31 is withdrawn at the head of the third column 3 .
  • the head of the third column 3 is lower than the head of the first column 1 , thus facilitating this transfer by gravitational flow.
  • FIG. 1 shows a condenser 9 which is a bath vaporizer
  • FIG. 2 shows a film vaporizer 9
  • the flow 21 withdrawn from the condenser is a two-phase flow and passed to the head of the second column as in FIG. 1 . No flow 17 is produced.
  • FIGS. 3 and 4 are variants of FIGS. 1 and 2 , respectively showing the case where the vaporizer 11 is absent or placed elsewhere other than below one of the columns. In this case, the three columns rest directly on the floor surface 27 .
  • FIGS. 5 and 6 respectively show variants of FIGS. 1 and 2 , where the second column contains just one reboiler, the bottom reboiler 5 .
  • the second column is naturally shorter.
  • the bottom reboiler 5 may be heated by nitrogen or air, which is possibly compressed, or possibly cold compressed.
  • the first pump is the pump 13 used for raising liquid from the bottom of the third column to the overhead condenser of the first column.
  • the second pump used in the case where the oxygen is required in pressurized form, is used to pressurize the liquid oxygen.
  • the difference in pressure between the columns should suffice to entrain the liquid.
  • the first column 1 contains relatively low packing densities (for example a density of 250 to 500 m 2 /m 3 ) and the second and/or third column contains relatively high packing densities (600 to 1000 m 2 /m 3 ) in order to achieve the highest possible first column 1 , and the lowest possible second and/or third column 2 , 3 so that the flow may take place by gravitational force between the vaporizer located above the first column to the second and/or to the third column.
  • the passage of the liquids in the pipes 21 , 35 is facilitated in this manner.
