Description

Apparatus and method for seperating air in low teperature
The present invention relates to a kind of device and method of low temperature air separating, this device comprise that a compressed machine and purifier lead to the input channel of Distallation systm by main heat exchanger and from Distallation systm by product pipeline to main heat exchanger, above-mentioned Distallation systm has a rectifying column at least, the filling of subregion at least of at least one rectifying column orderly filler.
A lot of similarly air separation units and relevant method thereof have been known.The disclosed air separation unit that has the parts of producing argon among disclosed double tower air separation unit or the EP-A-0377117 among disclosed single tower air separation unit, the EP-A-0316768 among the EP-A-0241817 for example.In addition, in the specification of EP-A-0377117, also disclosed in rectifying column of air separation unit and pure argon column and loaded a kind of orderly filler.
A kind of air separation unit that orderly filler is housed has also been described in EP-A-0321163, wherein, the lower pressure column of two-stage air separation unit filler is housed to the small part section.With only compare this method and reduced pressure drop with the tower of conventional rectifiying plate, therefore, its operating pressure is lower under identical product technology condition, thereby has reduced energy consumption, but has improved the manufacturing expense of rectifying column.
In view of the above, task of the present invention is that to begin the method that part mentioned with this specification be that improve on the basis, so that it is more favourable than above-mentioned technology economically, especially cost of equipment is lower.
The technical scheme that solves above-mentioned task is that the interior filler of part section that is seated in rectifying column is made up of the folded sheet that is arranged parallel to each other, folding thin slice is made by paper tinsel shape material, have the hole on it, adjacent thin slice is always contacted, and has smooth surface at first substantially between two flangings.
The notion of above-mentioned " smooth " (except the flanging) is meant the situation that does not have smart rough injustice at sheet surface, in fact refer to the projection and the embossing (referring to the arbitrary liquified mixt in liquid air or the constituent of air herein) that do not exist the influence of the mobile generation significant of working fluid on the sheet surface, rill or embossing that the lines degree of depth obviously surpasses paper tinsel thickness particularly can not occur.Preferably the deviation of the unevenness that under any circumstance allows is less than paper tinsel thickness, and it is slightly a little bit smaller to can be compared to paper tinsel thickness most, and the paper tinsel thickness of making thin slice preferably is about 0.1-0.2mm usually less than 1mm.
Also can exist to teach skill effect not have the less coarse uneven part of material impact at the used smooth filler of air separation unit of the present invention, this coarse uneven part for example can be caused by manufacturing process.
Herein, the smooth performance of sheet surface is crucial, and it should be because of porose not being affected on the thin slice.For example can go out above-mentioned hole by brill, cutting or Milling Process, the hole is evenly distributed or non-uniform Distribution at sheet surface, and the ratio in hole for example can be 5% to 40%, preferably is about 15% to 20%.
The specific area of employed filler is generally 350m in the air separation unit of the present invention 2/ m 3To 750m 2/ m 3Adopt the specific area height to 1200m in some applications 2/ m 3Or higher filler is favourable.What should propose emphatically at this is that the present invention is applied to German patent application P ... method and apparatus in (internal document H 92/30=H 1929) is especially favourable.Sheet fold can be become the shape (being folded into zigzag) on more sharp-pointed limit, perhaps also can be folded into the shape (corrugated) on not too sharp-pointed limit, can also be folded into other shape.
From many disclosed documents, learn, similar with its feature of laminar orderly filler usually to the filler that the present invention uses.But, be used for other purposes (for example being used for the separation of hydrocarbon) and be well known that by the folding mass transfer parts that form of the metal forming of punching.In open source literature early, once inquired into the surface texture (for example DE-C-2722424 or DE-B-2722556) of thin slice, only mentioned a kind of sheet surface fine structure (rill) for liquid distribution particular importance on sheet surface.
For a period of time, people have begun in cryogenic technique particularly to use in air separation and are mainly used in other so far and separate the purpose filler, but just well-known fillers is used for air separation technology unalterablely, in EP-A-0321163 european patent application prospectus even mention the special construction shape of filler and air separation is irrelevant.
The present invention has developed a kind of filler that is specially adapted for air separation.In the substantive test digital proof of carrying out on the experimental rig of a costliness obtaining under the condition of commercial air separation, when air rectifying, the routine techniques scheme of the distribution effect of meticulous rill is obsolete.With expect opposite, smooth porose filler is poor unlike the centrifugation of same nature rill filler, surprisingly be the separating effect of this filler even better.
Compare with the rill filler, adopt filler of the present invention except that manufacturing expense is low, also reduce the height of the rectifying column (one or several) of having loaded this filler, perhaps under same height, improved the purity of product and/or increased output, therefore reduced the expense of whole air separation unit.
The filler thin slice is preferably made by sheet metal.Preferably preferentially select for use substantially to be the sheet metal of aluminium, for example aluminium alloy or be essentially the sheet material of fine aluminium.Also the available copper sheet alloy is made thin slice except that aluminium.In second kind of modification, thin slice mainly is made of copper.
Usually, the used filler of the present invention or in the high oxygen concentration compression method used also available plastics of other filler for example the PTFE polytetrafluoroethylene (PTFE) make.In addition, also useful ceramics or glass material for example nonmetal oxide or metal oxide and nonmetal oxide mixture or be coated with the last layer above-mentioned material and make this class filler because they are nonflammable.
If it is that high-pressure tower and lower pressure column are then very favourable that the Distallation systm of air separation unit of the present invention has a double tower.In this case, preferably filling material in the part section of the lower pressure column in air separation unit of the present invention especially loads the filler with smooth surface in this part section or in one of part section.
If Distallation systm has a crude argon column, the present invention can bring benefit especially.In the ordinary course of things, crude argon column is connected with the lower pressure column of twin-stage tower by at least one argon conveyance conduit, certainly crude argon column also can be used for the single-stage tower that nitrogen oxygen separates and be connected.
In this class air-separating plant of the present invention, if at least a portion section of crude argon column filling filler or even be favourable at most of section device filler of crude argon column.Best, use as the described smooth filler of claim 1 characteristic at least in part therein.
Under the situation of double tower air separation, also can filler be set at least a portion section of high-pressure tower.Preferably also use or only use smooth filler herein.
In addition, the invention still further relates to a kind of method by the described low temperature air separating of claim 13-23, air separation unit described above carries out work according to this method.
Below in conjunction with accompanying drawing, use embodiments of the invention, the present invention will be described in more detail.Apparatus and method shown in Figure 1 are according to being illustrated as two stage rectification; But the present invention also can be used for the main air separation method, equally also can be used for the above rectificating method of two-stage.That should emphatically point out is the German patent application P that also can be used in the same time period ... object lesson during the explanation of (internal document H 92/30=H 1929) is received.
