Definitions

  • the present invention relates to a heat exchanger intended for the vaporization of a liquid by heat exchange with a second fluid, as defined in the preamble of claim 1. It applies in particular to installations for the distillation of l 'air.
  • the liquid oxygen which is in the bottom of the low pressure column is vaporized by heat exchange with the nitrogen gas taken off at the head of the medium pressure column.
  • the temperature difference between oxygen and nitrogen made necessary by the structure of the heat exchanger imposes the operating pressure of the medium pressure column. It is therefore desirable that this temperature difference is as small as possible, in order to minimize the expenses linked to the compression of the air to be treated injected into the medium pressure column.
  • a heat exchanger of the type comprising a parallelepiped body formed by an assembly of parallel vertical plates defining between them a multitude of flat passages, means for distributing the liquid in two stages in a first set of passages, provided at the upper end of each of these passages, and means for sending the second fluid into the remaining passages (FR-A-2 007 887).
  • the two distribution stages are obtained the first thanks to an oblique wave, the second thanks to holes.
  • a double distribution of the liquid comprising a final distribution by means of holes is also provided in FR-A-2 017 807.
  • the object of the invention is to provide a heat exchanger of the same type which is better suited to the actual operating conditions of air distillation installations.
  • the subject of the invention is a heat exchanger of the aforementioned type as defined in claim 1.
  • Another subject of the invention is an installation for separating air by distillation, of the type comprising a first distillation column operating under relatively high pressure, a second distillation column operating under relatively low pressure, and a heat exchanger allowing to put the liquid oxygen in the tank of the second column in heat exchange relation with the nitrogen gas at the top of the first column, characterized in that the heat exchanger is as defined above, and in that that the installation comprises supply means for supplying liquid oxygen to said predistribution openings, and means for supplying gaseous nitrogen to said remaining passages.
  • FIG. 1 illustrates a possibility of installing an oxygen-nitrogen heat exchanger in an air distillation installation of the double column type.
  • This installation comprises a medium pressure column 1 at the bottom of which the air to be treated is injected, under a pressure of the order of 6 bars absolute.
  • the oxygen-enriched liquid which is collected in the tank of column 1 is sent under reflux in the middle of the height of a second column (not shown), called the low pressure column, which operates slightly above atmospheric pressure.
  • the nitrogen gas which is at the head of column 1 is brought into heat exchange relationship with the liquid oxygen collected in the bottom of the low pressure column; the resulting condensed nitrogen serves as reflux in column 1 and in the low pressure column, while the resulting vaporized oxygen is returned to the bottom of the low pressure column.
  • the exchanger 2 consists of a sealed envelope 3, the main height of which contains a set of parallel plates 4 of shape rectangular aluminum, with a length of the order of 1 to 1.5 m and a height of the order of 3 to 6 m, between which waves also made of aluminum are fixed by brazing.
  • the space located above the plates 4 contains a liquid oxygen bath 5 supplied by a line 6 coming from the tank of the low pressure column and provided with a pump (not shown).
  • the latter can be controlled by a level regulator of the bath 5, which is shown diagrammatically by a level measurement tube 6A, or, as a variant, by a flow regulator.
  • a pipe 7 for returning oxygen vaporized above the bath 5 to the bottom of the low pressure column, resulting from the heat inputs at the pump and the pipes.
  • the set of plates 4 is supplied at its upper part with gaseous nitrogen by a horizontal feed box 8 which communicates by a pipe 9 with the head of the medium pressure column 1.
  • the evacuation of the condensed nitrogen takes place at the base of the plates 4 by a horizontal collecting box 10 which communicates by a pipe 11 with a guarded channel 12 disposed at the head of the column 1.
  • On the box 10 is stuck a pipe 13 for discharging the incondensable rare gases.
  • a pipe 14 connects the tank of the low pressure column to the space located in the casing 3 below the plates 4. This pipe penetrates vertically into this space through the bottom point of the casing 3, and its upper end is surmounted by a conical deflector 15. Also from the bottom of the casing 3 there is a pipe 16 intended to bring excess liquid oxygen to the bottom of the low pressure column.
  • the casing 3 has a parallelepiped shape.
  • the plates 4 define a multitude of passages intended alternately for the flow of oxygen (passages 17) and for the flow of nitrogen (passages 18). Over most of their height, the passages 17 and 18 each contain a wave 19 consisting of a corrugated perforated aluminum sheet with vertical generators.
  • the waves 19 of the nitrogen passages end, at the top as well as the bottom, before the waves 19 of the oxygen passages.
  • these waves of the passages 18 are extended by oblique waves of nitrogen collection (not shown) which lead to the entry of the manifold 10.
  • these same waves 19 are extended by oblique waves 20 of nitrogen distribution which emerge at the outlet of the feed box 8.
  • the nitrogen passages 18 are closed by horizontal bars 21.
  • each nitrogen passage comprises a liquid oxygen tank 22 containing a vertical wave 23 made of perforated aluminum sheet, with vertical generators, the thickness and pitch of which are clearly greater than those of waves 19.
  • the waves 23 have only a function of spacers between the plates 4, so as to allow the assembly of the exchanger by a single brazing operation.
  • the tanks 22 are open upwards to communicate with the liquid oxygen bath 5.
  • the waves 19 of the oxygen passages 17 extend downwards to the lower end of the plates 4, so that these passages are open down. These waves extend upwards to the upper edge of the bars 21, then are extended by a lining 24.
  • the latter consists of a wave of the "serrated" type which is illustrated in more detail in FIG. 6.
  • the wave 24 is an unperforated aluminum sheet with horizontal generators (so-called "hard way” arrangement with respect to the flow of liquid oxygen).
  • each horizontal or pseudo-horizontal facet 25 of the wave 24 is provided with a puncture 26 offset upwards by a quarter of a wave step.
  • the width of the punctures 26, measured along a generatrix of the wave, is of the same order as the distance which separates each of them from the two adjacent punctures located on the same facet 25.
  • each plate 4 comprises, above the lining 24, a horizontal row of holes 27 arranged at regular intervals over the entire length of the exchanger, the holes of the successive plates being arranged at the same height but in a staggered arrangement. As a variant, these holes could moreover be provided only in every second plate.
  • the oxygen passages are closed by horizontal bars 28, arranged at the upper end of the plates 4. To avoid the risk of obstruction of certain holes 27 by waves 23, these are interrupted for a short height at the level of said holes.
  • the regulating device of the pump for supplying the exchanger 2 with liquid oxygen maintains above the plates 4 a level of the bath 5 sufficient to overcome the various pressure drops which oppose the flow of oxygen.
  • the height of liquid oxygen above the plates 4 is for example of the order of 20 cm.
  • Liquid oxygen fills the reservoirs 22 and passes through the holes 27, at a flow rate defined by the passage section of the latter and by the height of liquid which overcomes it. As this height is constant in steady state, the flow of liquid oxygen is that supplied by the pump for raising this liquid.
  • the holes 27 therefore ensure a rough predistribution of the liquid oxygen all along the passages 17, and the liquid oxygen thus pre-distributed reaches the lining 24, which ensures a fine distribution over the entire length of each passage 17.
  • Liquid oxygen thus enters waves 19 by flowing perfectly uniformly over all the walls (waves 19 and plates 4) of the passages assigned to it, that is to say by forming on these walls a continuous descending film.
  • the nitrogen gas arrives in the exchanger through the box 8 and the distribution waves 20, then flows down along the passages 18. In so doing, it gradually gives up heat to the oxygen. liquid which is in the adjacent passages 17, so that the oxygen vaporizes and that, simultaneously, the nitrogen condenses.
  • the condensed nitrogen is collected in the box 10 and flows through the pipe 11 into the channel 12.
  • this liquid overflows from the channel and falls into reflux in the medium pressure column after a portion has been withdrawn through a pipe 11A to ensure the reflux of the low pressure column. This creates suction in the passages 17, which ensures the circulation of nitrogen.
  • the liquid oxygen flow rate is adjusted so as to guarantee an excess of liquid oxygen over the entire height of the plates 4.
  • a total vaporization of the oxygen in a region of the passages 17 would lead to this location at a concentration of acetylene dissolved in liquid oxygen, which could cause a local explosion.
  • this risk of explosion it would also result in a drop in performance of the exchanger by neutralization of the non-wetted surface. This risk is limited thanks to the high efficiency of the fine distribution provided by the lining 24.
  • the bars 21 which upper limit the passages 18 are arranged at the upper end of the plates 4, like the bars 28.
  • the holes 27 are removed and replaced by vertical holes 29 drilled at regular intervals in the bars 28, all along these.
  • the liquid oxygen in the bath 5 flows through the holes 29, at a flow rate corresponding to that of the pump for raising the liquid oxygen, and is thus predistributed over the entire length of the passages 17; these liquids then fall onto the lining 24 located just below (this lining has been shown very schematically in FIG. 3).
  • the lining 24 ensures a uniform fine distribution of the liquid oxygen over the entire length of the passages 17, and this liquid then flows along the waves 19 and the corresponding walls 4.
  • the heat exchange between oxygen and nitrogen begins during the passage of liquid oxygen through the linings 24, which are at the same level as the nitrogen gas distribution waves 20.
  • the holes 29 of the bars 28 instead of being of a constant diameter over the entire height of these bars, can have a diameter widened in the greater part of their height by a counterbore 29A made from the bottom.
  • FIG. 5 shows that similar holes can also be obtained by perforating the upper core 30 of U-shaped profiles constituting the bars 28.
  • the advantage of these two embodiments lies in the fact that the useful part of the holes 29, which defines the liquid oxygen passage section is short and therefore less subject to the appearance of blockages or undesirable vaporization.
  • the vaporized oxygen is evacuated from below at the same time as the excess liquid oxygen.
  • the vaporized oxygen is free to escape both from the top and from the bottom.
  • the exchanger of FIG. 6 is identical to that of FIG. 2 from the bottom of the plates 4 to the level of the upper edge of the bars 21 which limit the nitrogen passages 18 above.
  • each plate 4 has a horizontal row of holes 31. Above these, the plates 4 extend over a significant height, up to a level higher than that of the surface free from the liquid oxygen bath 5.
  • waves - spacers 32 with vertical generators similar to waves 23 in FIG. 2.
  • a free space 33 is provided at the holes 31, above the waves 19, and this space is surmounted, from bottom to top by the lining 24 previously described, by a bar 28 with holes 29 similar to those of FIG. 3, and by a wave-spacer 34 similar to waves 32 but with horizontal generatrices .
  • the bath 5 is fed laterally by a feed box 35 located above the box 8 and opening into the spaces occupied by the waves 34.
  • the bars 36 which close on this side the oxygen passages 17 extend upwards only up to the level of the upper edge of the bars 28.
  • the bath 5 overcomes the bars 28 and, as in FIG. 1, the liquid oxygen flows through the holes 29 in the lining 24, which distributes it uniformly in a fine manner, then trickles through the passages 17 in exchange for heat with the nitrogen contained in the passages 18.
  • the vaporized oxygen can be evacuated either downwards, as previously, or upwards through the holes 31 and the spaces containing the waves 32, as indicated by arrows on the figure 6.
  • the nitrogen circuit is conventional. It can therefore be replaced by other known types of nitrogen circuits, in particular by those described in patent FR-A-2 431 103 of the applicant.
  • one or more heat exchangers according to the invention can be installed inside a double air distillation column whose low pressure column is superimposed on the medium pressure column.
