Definitions
- This invention is concerned with improvements in and relating to packing elements for use in fluid-fluid contact apparatus.
- a wide variety of packing elements has been proposed for use in fluid-fluid contact apparatus. Examples of these include Raschig rings. Pall rings, Tellerette rings and Mini-rings. Such elements are used, for example, in apparatus such as distillation columns, reaction towers, gas scrubbing apparatus and the like.
- the present invention provides a packing element comprising an open-ended tubular member having a row of perforations extending around the member adjacent each end of the member.
- the perforations are relatively small and in this regard differ markedly from the apertures commonly found in packing rings.
- the perforations may be of any desired cross-section, polygonal or curvilinear, but are typically and conveniently circular in cross-section.
- the diameter of the perforations will, to some extent, depend upon the size of the element, larger elements having larger perforations and smaller elements having smaller perforations.
- the dimensions of the perforations may be expressed as a percentage of the length of the tubular member; for example they may be from 1 to 5%, of the overall length of the tubular member.
- the perforations are suitably from 1 to 5 mm in diameter, preferably from 2 to 4 mm in diameter.
- the spacing between centres of the perforations in the rows will also depend upon the size of the packing element and thus may be expressed in terms of the diameters of the perforations, in which case the spacing is suitably from 2 to 5 diameters.
- the rows of perforations may be single rows or may comprise two or more rows, in which case perforations in adjacent rows may be staggered.
- the end rows of perforations are suitably, in terms of perforation diameters are suitably from 1 to 5 diameters from the ends.
- the tubular member forming the body of the packing element may be of any desired cross-section, polygonal or curvilinear, but is generally circular in cross-section, that is the tubular member takes the form of a hollow cyclinder.
- the tubular member takes the form of a hollow cyclinder.
- the ratio of the diameter of the tubular member to its height or length may be unity, as in the case of conventional raschig or Pall rings. However it is generally preferred that the ratio of diameter to height be greater than unity, suitably at least from 1.5 :1 and preferably from 2:1 to 10:1, more preferably 2.5:1 to 5:1.
- the tubular element is preferably provided with an outwardly directed flange at each end since this serves not only to strength the ring but to improve its effectiveness, particularly in combination with the rows of perforations.
- Such flanges may extend generally normal to the surface of the tubular member or may be angled with respect to that plane so that the rim of the flange extends beyond the end of the tubular member both radially and longitudinally.
- the tubular members are suitably provided with ribs or tabs extending inwardly from the walls of the member.
- ribs or tabs which also serve to increase the available surface area of the elements, may meet (and indeed may be joined) at or about the centre of the tubular member or may extend only part-way into the member.
- the walls of the tubular member may be provided with apertures in a conventional manner and located between the rows of perforations. Such apertures will generally be of greater cross-sectional area than the perforations forming the rows and may, for example in the case of metal rings, be associated with inwardly directed tabs.
- the packing elements of the invention may be formed of any suitable material, commonly metal or plastics material. Suitable metals include mild steel, stainless steel and aluminium and its alloys. Suitable plastics materials include polypropylene and nylon.
- the packing elements of the invention may be employed in a wide variety of fluid-fluid contact apparatus, such as distillation or fractionation columns or gas scrubbing apparatus.
- the elements will, as is generally the practice, be supported upon liquid-pervious supports and may be stacked in an ordered array.
- the elements of the invention are particularly suitable for dumpiag into the apparatus and thus will generally be used in a so-called "dumped" array.
- Figure 1 is a side view of a packing element in accordance with the invention.
- FIG 2 is a plan view of the elements shown in Figure 1.
- a packing element in accordance with the invention comprises a tubular member 1 provided with flanges 2 at its ends and rows of perforation 3 adjacent each end.
- Tubular member 1 is further provided with apertures 4 from which spring inwardly directed tabs 5.
- Agent LAMB, John, Baxter; Marks & Clerk, 57/60 Lincoln's Inn Fields, London WC2A 3LS (GB).
- a packing element comprises an open-ended tubular member (1) having a row of perforations (3) adjacent each e of the member.
