Definitions

  • This invention relates to new and useful improvements in bubble towers.
  • bubble towers are employed in the refining industry for fractionating hydrocarbon liquids and it has been the practice to construct such towers by mounting a plurality of bubble trays at different elevations within a cylindrical tank.
  • the hydrocarbon liquid is suitably heated and is then conducted to the tower to separate the liquid and vapors, fractional condensation of the vapors being affected by passing said vapors upwardly through the tower and contacting said vapors with a downwardly flowing liquid reflux at the multiplicity of levels, as determined by the location of the bubble trays.
  • the usual bubble trays are ordinarily constructed of metal and are supported at their marginal edge portions on an annular flange secured to the inside wall of the tank. Since there is no support for the intermediate ,or central.
  • each tray must be constructed of a relatively thick metal so as to give said tray sufllcient rigidity and strength.
  • the trays are, of course, contacted by the hydrocarbon liquid and are, therefore, subjected to the corrosive action of the acids present in said liquid and are also contacted by the vapors within the tank; for this reason, it is desirable to construct the trays of stainless steel, or other corrosion resistant metal, so as to prolong the life of said trays.
  • a metal, such as stainless steel which is resistant to corrosion is comparatively expensive and to construct a tray of this material and of sufficient thickness 'for the necessary rigidity and strength would be prohibitive because of the excessive cost.
  • the bubble trays be constructed of a relatively thin and light metal which is resistant to corrosion and it is one object of this invention to provide a bubble tower, wherein such trays may be employed, whereby the disadvantages present in the usual type of trays now in general use, are obviated.
  • An important object of the invention is to provide an improved bubble tower wherein transversely extending truss members are mounted within the tank and are adapted to support the bubble trays; the truss members serving to support each tray substantially through its entire area, whereby said tray may be constructed of a thin metal which is resistant to corrosion since REISSUED oEc 91941 the truss members give the tray the necessary rigidity and strength.
  • a particular object of the invention is to provide a bubble tower having the bubble trays supported on transverse truss members, which members are fabricated of a light metal, such as stainless steel, whereby said members are resistant to corrosion and'yet are of suflicient strength to support said tray.
  • Another object of the invention is to provide an improved bubble tower of the character described, wherein each tray floor may be constructed in sections, with improved means of fastening the sections to their supporting members; the fastening means being such that it is unnecessary to provide bolt holes in the sections and yet said sections may undergo limited movement or breathing due to thermal contraction and expansion.
  • a further object of the invention is to provide a bubble tray constructed of a relatively thin metal and which has openings therein for receiving the usual bubble cap risers, said openings being surrounded by an annular lip or flange which is formed by bending the metal of which the tray is formed; said lip not only providing a means for co-acting with the riser to hold the same in place, but also acting as a reinforcing rib to add rigidity to the tray.
  • Another object of the invention is to provide animproved bubble tower having its inner wall covered by a corrosive resistant liner and also having a plurality of bubble trays constructed of relatively thin stainless steel therein, together with improved risers and downcomers, also constructed of stainless steel, whereby all of the interior metal of the tower is non-corrosive and the life of the tower is materially increased.
  • Still another object of the invention is to provide a bubble tower, wherein the take off wells are fabricated of stainless steel and also wherein improved bubble caps constructed of stainless steel are employed on the trays of said tower.

  • the numeral III I designates a cylindrical tank which forms the shell of a bubble tower. Only a portion of said tank is shown and it is pointed out that said tank may be of any desired diameter and height. A plurality of transversely extending bubble trays are mounted at spaced elevations throughout the height of the tank in the usual manner, and said trays will vary in number according to the size of the tank. Three of the bubble trays A, B and C have been shown, but it is noted that additional trays (not shown) are located above and below the trays illustrated.
  • the operation of the bubble tower in fractionating the hydrocarbon liquid which is conducted through the trays of the tower forms no part of the present invention and any of the conventional methods of operation may be employed.
  • the invention has to do primarily with the construction of the tank and particularly with the construction and mounting of the bubble trays and, as clearly shown in Figures 1 and 4 to 8, an annular flanged ring II is secured to the inside wall of the tank III adjacent the bubble tray A.
  • This ring- is welded or otherwise secured to the tank wall and is present in all bubble tower tanks, being ordinarily employed for supporting the tray floor thereon.
  • an inner liner L which is made of a corrosive resistant material, covers said inner wall.
  • This liner is constructed of a plurality of sections Ill, each of which extend vertically between the flanged rings ll.
  • Each section is formed with vertical flanges at its edges and these flanges may be welded, or otherwise secured, to vertical ribs IDA which are fastened to the tank wall.
  • an offset [0B is formed in the member adjacent each vertical flange and such offset permits the main portion of each section between the flanges to undergo limited expansion and contraction due to temperature changes.
  • the liner L being of a corrosive resistant material, protects the wall of the tank.
  • a plurality of transversely extending trusses T are mounted within the tank.
  • the trusses have their ends secured to the flange II, as will be explained, and extend in parallel relation across the interior of the tank, whereby the tray floor may be supported thereon.
  • the trusses be of non-corrosive metal, such as stainless steel, so as to resist corrosion caused by acids present in the hydrocarbon liquid flowing through the tower and it is also desirable that said metal be relatively thin, whereby the cost thereof is held within reasonable limits and also whereby the trusses will be light in weight so as to be readily handled.
  • each truss T is fabricated of relatively thin stainless steel and includes a longitudinal top channel I! ( Figures 3 to 9) which has its flanges l3 directed downwardly.
  • a bottom angle bar H is spaced from the channel bar and is disposed centrally beneath the same, extending substantially throughout the length thereof.
  • the flanges of the channel are secured to the angle bar by inclined braces or struts I5 which have their upper ends fastened to the inner sides of the flanges l3, while their lower ends overlie and are connected to the angle.
  • the connections' between the braces or struts and the channel and angle bar are preferably made by spot welding but other means of fastening may be employed. As is clearly shown in Figures 8 and 9,'
  • braces are constructed of thin stainless steel and may be made from the same strip of material from which the channel member I2 is formed, whereby the stainless steel may be pur-' the top channel member l2 terminate adjacent the annular flange II which is secured to the inner wall of the tank. The top of said channel is flush with the top of the flange.
  • each truss T For securing the ends of each truss T to the tank wall, a pair of retaining plates l6 are secured to 'eachend of the truss ( Figures 5 and 6) and these plates are welded or otherwise secured together in abutting relation.

  • Nuts 24 are screwed onto the lower ends of said bolts and serve to clamp the longitudinal edge portions of the adjacent floor sections between the overlying washers 22 and the channel
  • Each floor section 20 is formed with a plurality of relatively large openings 25 which permit vapors from below the tray A to rise above said tray.
  • the material of which the section 20 is constructed is bent upwardly to provide an annular inclined lip or flange 26 around each opening.
