Definitions

  • the present invention relates to a distillation column comprising at least one cross-corrugated packing module comprising a plurality of strips with their channel orientations inverted from one strip to the next, the strip being made of a sheet material and being of the type comprising corrugations that form alternately first main peaks directed along a first direction and second main peaks directed along the opposite direction, the corrugations defining channels, each channel lying between two first or second adjacent main peaks forming edge peaks of the channel, and each channel having two channel legs that are joined together by a top main peak, the channels having a general orientation that is inclined to a general flow direction of the said liquid, the strip furthermore comprising at least one inverted portion which lies entirely within the cross section of one of the channels and which joins together the two channel legs, the inverted portion comprising a first intermediate peak oriented-in the opposite direction to the top main peak of the channel.
  • packing is understood to mean a device intended for mixing a phase and/or for bringing several phases flowing co-currently or countercurrently into contact with one another.
  • a heat and/or mass exchange and/or a chemical reaction may in particular take place in the packing.
  • One particular application of the invention lies in the columns separating gas mixtures, especially air distillation columns.
  • modules comprise corrugated metal sheets placed vertically, the corrugations of which sheets are oblique with respect to a general fluid flow direction in the installation and are inclined alternately, generally crossed at 90°, from one sheet to another.
  • the packing modules are slipped into the distillation column so that the sheets of one module are angularly offset with respect to the sheets of an adjacent module about the axis of the column, generally by 90° from one module to another.
  • a packing strip of this type is known from document EP-A-1 029 588, the corrugations of which form peaks and valleys joined together by corrugation legs defining channels.
  • This strip includes inverted portions, also called “serrations”, which lie within each channel, each inverted portion forming a single intermediate peak. The inverted portion defines an angle of 90° with each corrugation leg to which it is joined.
  • this strip When this strip is manufactured by bending a thin flat metal sheet, the material forms tears or pleats.
  • the finished packing strip therefore deviates from its desired geometrical shape, thereby reducing the mass or heat exchange performance of the finished strip.
  • the object of the present invention is to alleviate the above drawbacks and to propose a packing strip that is easy to manufacture from a thin flat metal sheet and results in substantial heat and/or mass exchange.
  • the subject of the invention is a column according to claim 1 .
  • the strip of the column according to the invention includes one or more of the following features:
  • the subject of the invention is also a process for manufacturing a strip made of folded metal sheet, of the type comprising corrugations that form alternately first main peaks directed along a first direction and second main peaks directed along the opposite direction, the corrugations defining channels, each channel lying between two first or second adjacent main peaks forming edge peaks of the channel, and each channel having two channel legs that are joined together by a top main peak, the channels having a general orientation that is inclined to a general flow direction of the said liquid, the strip furthermore comprising at least one inverted portion which lies entirely within the cross section of one of the channels and which joins together the two channel legs, the inverted portion comprising a first intermediate peak oriented in the opposite direction to the top main peak of the channel, the inverted portion furthermore including a second intermediate peak oriented in the direction of the top main peak, as defined above, characterized in that the process comprises the following step:
  • FIG. 1 is a schematic view, in longitudinal section, of a mass and/or heat exchange column according to the invention, comprising cross-corrugated packing modules;
  • FIG. 2 is a plan view of part of a packing strip of a column according to the invention.
  • FIG. 3 is a perspective view of part of the strip of FIG. 2 ;
  • FIG. 4 is a sectional view of the strip along the line IV-IV of FIG. 2 , on a larger scale.
  • FIG. 1 shows a mass and/or heat exchange column EC according to the invention, having a vertical general axis X-X.
  • the column EC is for example a cryogenic distillation column, especially an air distillation column.
  • the column EC comprises, at its upper end UE, a liquid inlet LI emerging in a liquid header LH which distributes the liquid over the cross section of the column EC, and a vapour outlet VO. At its lower end LE, it comprises a vapour inlet VI and a liquid outlet LO.
  • the column EC furthermore includes a cylindrical shell S.
  • the column EC defines a general fluid flow direction D f , which runs vertically.
  • a packaging module PM 1 which favours the spreading of the liquid transversely to the X-X axis, is placed in the shell S directly below the header LH.
  • a module PM 1 is known per se and is for example a packing module comprising a cross-corrugated packing with perforations or striations.
  • a plurality of packing modules PM 2 according to the invention is placed in the shell S beneath the module PM 1 .
  • a bottom support BS holds the packing modules PM 1 , PM 2 in place.
  • Each packing module PM 2 comprises a multitude of corrugated packing strips 2 .
  • the strips 2 have a mid-plane P (see FIG. 4 ) lying parallel to the general direction D f .
  • the strips 2 of a module PM 2 are placed against one another and in such a way that the planes P lie parallel to one another.
  • the planes P of the packing strips of two adjacent modules PM 2 are angularly offset about the X-X axis, preferably by approximately 90°.
  • FIG. 2 shows part of a packing strip 2 .
  • the strip 2 has two parallel edges, an upper edge 4 and a lower edge 6 , which lie perpendicular to the direction D f .
  • the strip 2 also has corrugations 8 which form alternately first main peaks 10 , directed in one direction (see FIG. 4 ) relative to the general mid-plane P of the strip 2 , and second main peaks 12 , directed in the opposite direction relative to the plane P.
  • the second peaks 12 form valleys.
  • the corrugations 8 form identical but alternately inverted channels 14 , each channel lying between two first 10 or two second 12 main peaks.
  • the channels 14 are open alternately in one of the two aforementioned directions and then in the other.
  • the intermediate main peak 12 or 10 forms the top main peak of the channel 14 in question, whereas the two adjacent peaks 10 or 12 form the channel edge peaks.
  • Two adjacent main peaks 10 , 12 are joined together by a channel leg 16 of straight section.
  • the channels 14 , and consequently the peaks 10 , 12 lie along a channel direction D c that is inclined at an angle ⁇ to the edges 4 , 6 (see FIG. 2 ).
  • the directions D c of two adjacent strips 2 of a module PM 2 are inverted one with respect to the other.
  • each channel 14 has a first circular arc 18 of radius of curvature r 1 , which forms the top main peak 10 .
  • a main straight section 20 of the channel leg 16 is joined tangentially to this circular arc 18 on either side of the latter.
  • This straight section 20 has a length d 1 measured between the join 24 (see below) and the circular arc 18 .
  • the two straight sections 20 make an angle ⁇ between them.
  • the strip 2 furthermore includes, in each channel 14 , a multitude of identical inverted portions 22 .
  • FIG. 4 shows one of these inverted portions 22 .
  • the inverted portion 22 lies entirely within the cross section of the channel 14 , that is to say that the portion of the strip 2 , which lies inside the thickness e of the corrugation legs 16 , does not form part of the inverted portion 22 .
  • the inverted portion 22 joins the two legs 16 of the channel 14 together and is joined to them at two joins 24 . It forms a first intermediate peak 26 directed in the opposite direction to the top peak 10 of the channel, and two intermediate peaks, a second intermediate peak 28 and a third intermediate peak 30 , which are oriented in the direction of the top main peak 10 and lie on either side of the intermediate peak 26 .
  • the cross section of the inverted portion 22 comprises three circular arcs 32 , 34 , 36 .
  • the circular arcs 34 , 36 have the same radius of curvature r 2 and form the second 28 and third 30 intermediate peaks, whereas the circular arc 32 has a radius of curvature r 3 (>r 2 ) and forms the first intermediate peak 26 .
  • Extending between the circular arc 32 and each of the circular arcs 34 , 36 is a straight section 38 of the inverted portion 22 , which straight portion is joined tangentially to each of the circular arcs 32 , 34 , 36 .
  • the straight sections 38 have the same length d 2 .
  • the circular arcs 34 , 36 are joined tangentially to the channel legs 16 . As a consequence, there is little stressing of the metal sheet during deformation.
  • Each of the two straight sections 38 makes an angle a with the adjacent corrugation leg 16 .
  • the developed length of the inverted portion 22 is identical to the developed length of the two main straight sections 20 and of the circular arc 18 .
  • the material is not stretched, or only slightly so, during bending.
  • the channel 14 has a height h which is measured between the top main peak 10 of the channel and a plane Q defined by the two adjacent main peaks 12 .
  • the first intermediate peak 26 lies approximately at the location of the barycentre B of the cross section of the channel. It is at this point that there is the highest concentration of mass or the highest temperature of a gas flowing in the channel 14 . Consequently, the strip 2 results in substantial heat and/or mass exchange.
  • channel 14 and the inverted portion 22 are symmetrical with respect to a plane of symmetry A, perpendicular to the planes P and Q, the plane of symmetry being defined by the top main peak 10 and the first intermediate peak 26 .
  • the radii of curvature r 1 , r 2 , r 3 of the corrugation 8 and of the inverted portion 22 are preferably at least 1 mm and in particular at least 2 mm, thereby making it easier to form the inverted-portion 22 without material rupture.
  • the strip 2 according to the invention is manufactured according to a process comprising the following steps:
  • the strip 2 Owing to the presence of at least one second intermediate peak, the strip 2 is only slightly deformed at the joins 24 . There is therefore little likelihood of the strip 2 tearing at these joins. Because the developed length of the corrugation 8 is the same as that of the inverted portion 22 between the joins 24 , the finished strip 2 is smooth and has a thickness e which is approximately the same over its entire surface. In addition, a risk of the strip 2 fracturing during bending is low.
  • step (b) is carried out before step (a).
  • steps (b) and (c) are carried out at the same time. Thus, it is unnecessary to synchronize the cutting and bending tools for the inverted portion.
  • the intermediate peak 26 is placed close to the barycentre B of the cross section of the channel 14 , for example at a distance from this point B of less than 0.20 times the height h of the channel 14 .
  • the intermediate peak 26 remains within a high concentration or high temperature region.
  • the packing strip 2 also includes the following features:
  • the invention also relates to a cryogenic distillation installation and in particular to an air distillation installation comprising at least one packing module as defined above.
