  • This invention relates to storage tanks where heat gain or loss is to be avoided and cost is reduced. More particularly, this invention is concerned with means of increasing the storage capacity, without increasing the size, of an insulated storage tank for storing liquids at low temperatures, such as liquefied gases stored at about atmospheric pressure or slightly above atmospheric pressure.
  • a conventional tank for storing liquefied gases at about atmospheric pressure or slightly thereabove consists of a metal shell having an essentially flat metal bottom, an essentially vertical wall, usually cylindrical, and a metal roof, generally sloped in the form of a conical section or in the form of a domed roof, supported by the wall.
  • the bottom rests on an insulated base and the wall is externally insulated.
  • the roof is also usually insulated externally.
  • Insulating the roof is costly since it is difficult to shape the insulation to the roof contour and to make it weathertight'. This problem was considered and met by an improved insulated tank as shown in Sattelberg et al. U.S. Pat. 3,352,443 which eliminates the insulation from the roof and adds an insulated ceiling suspended from the inside of the noninsulated roof. The suspended insulated ceiling hangs from the sloped metal roof and extends to approximate contact with the metal wall to thereby provide a totally insulated storage space.
  • an improved enclosed andlor insulated storage tank which coniprises a metal shell having an insulated metal bottom, an insulated metal wall, a sloped metal roof, a metal canopy member extending from near the top of the wall inwardly and upwardly and terminating in spaced relationship from the roof, and an insulated ceiling suspended from the inside of the roof having its periphery adjacent to, and conforming with, the internal peripheral terminus of the metal canopy, and insulation between the canopy member and the roof.
  • the metal canopy member comprises an upwardly and inwardly directed extension of the. metal wall and raises the height to which a liquid can be stored in the tank significantly above the level to which it could be raised if the metal wall lacked such an internal extension.
  • the metal canopy member in some respects might be considered a partial internal roof since it more or less follows the general contour described by the roof to thereby provide space between it and the roof for holding and securing, insulation material in place.
  • the suspended insulated ceiling still occupies a substantial part of the area across the upper part of the tank which must be in-' sulated against heat leak in order that the temperature of a stored liquid can be controlled.
  • a tank built using the combination metal canopy member and suspended insulating ceiling will have I to l percent more usable storage capacity than a similar tank having the same metal shell, but without the metal canopy member, and having the periphery of the suspended ceiling in contact with the wall.
  • the canopy member as employed in the tank can have any suitable shape and can be fabricawd of one or more pieces. It is advisably made of metal plate of sufficient strength to withstand the stresses to which it will be subjected.
  • the term "sloping roof” is intended to include roofs having surfaces such as generated by rotating a line, curved or straight, about a vertical axis.
  • the roofs thus can be conical, semispherical, elliptical or otherwise curved with the highest point being at the axis and the lowest point at the periphery or circumference of the roof.
  • FIG. 1 is a vertical sectional view through a double-bottomed double-walled single roofed tank having a canopy member to increase storage capacity;
  • FIG. 2 is an enlarged vertical sectional view of that portion of the tank of FIG. 1 showing the wall and roof juncture area and a frustoconical section canopy extension which permits increased storage capacity in the tank;
  • FIG. 3 is a vertical sectional view similar to FIG. 2, but showing an arcuate canopy member
  • FIG. 4 is a vertical sectional view, similar to FIG. 2, showing a canopy structure having a horizontally inwardly directed element from which a vertical wall extends upwardly to thereby increase the capacity of the tank;
  • FIG. 5 shows a canopy member used on a single shell tank to increase the liquid storage capacity thereof.
  • the tank It is mounted on ring wall foundation 11. Within ring wall foundation 1! is placed compacted support material 12.
  • the tank 10 has an outer shell comprised of a bottom 13, cylindrical wall 14 and a domed roof 15.
  • tank 10 has an inner shell composed of bottom 16 and sidewall 1?. Insulation 18 is laced between outer bottom 13 and inner bottom 16. This insulation is capable of withstanding the pressure applied when the tank is fully loaded.
  • the space between outer wall 14 and inner wall 17 is insulated in part by glass fiber blankets I9 placed against the outer surface of inner wall 17 and by filling up the remainder of the space with granular insulation 20. As shown more clearly in FIG. 2, one or more insulating blankets 19 are placed against inner wall 17.
  • canopy member 21 Extending inwardly and upwardly from inner wall I! is canopy member 21, which is generally frustoconical. It is thus straight in vertical radial cross section. It can be readily formed of metal plate and joined at its lower end 22 to the top edge of inner wall 17 or at some other appropriate location along the upper portion of the inner wall. A stiffening vertical ring 23 is placed around the upper edge of canopy member 21 to make it more rigid. Other supports can be used as may be advisable.
  • a suspended ceiling 30 is supported by domed roof 15.
  • the suspended ceiling has a substantially flat horizontal deck 3! suspended by elongated members 32 from domed roof I5.
  • Elongated members 32 connect to the deck 31 and roof 15 by either brackets 33 and 34 or by direct welding to structural members on deck 31 and roof 15.
  • Granular or other insulation 35 is placed on top of deck 3
  • a gap is provided between ring member 23 and the edge of deck 31 so that contraction and expansion of each can take place freely.
  • the gap is spanned by an appropriate device such as a flexible membrane 36 in which a glass fiber blanket 37 is placed. Glass fiber blankets 38, a continuation of blankets 19, are placed in layers on top of canopy member 21 and then granular insulation 39 is placed thereon up to the bottom surface ofdomed roof 15.
  • FIG. 3 The tank structure of FIG. 3 is very similar to that described in conjunction with FIGS. 1 and 2, except that, in FIG. 3, the canopy member 40 in vertical radial cross section is arcuate and smoothly joins inner wall 17.
  • the other elements shown in FIG. 3 are the same as those described with reference to FIGS. 1 and 2.
  • the tank structure illustrated by FIG. 4 is also similar to that shown in FIG. 2 and the same elements have been identified with the same numbers as those which appear in FIG. 2.
  • the tank of FIG. 4 has a conical or domed roof 50 supported by outer wall 14. Extending inwardly in a horizontal direction is plate member SI which is joined at its outer edge 32 to the top root 30.
  • Membrane 55 spans the gap between the outer edge of deck 31 and the upper edge of cylindrical member 54 and supports a glass fiber insulating blanket 56.
  • Granular insulation 57 is piled on top of plate 51 until it reaches the roof 50 and to a height which corresponds approximately with the level of grandular insulation 35 placed on deck 31.
  • the tank structure of FIG. differs from those described with regard to FIGS. 1 to 4.
  • the tank structure of FIG. 5 has a single shell composed of bottom 16 (FIG. 1 a cylindrical wall 60 and roof 61 supported on the upper edge of wall 60. Any external shell insulation such as foamed-in-place polyurethane insulation 62 is placed around the outer surface of wall 60 and is covered by a vapor barrier such as sheet aluminum 63.
  • Canopy member 64 is joined at its lower edge 65 to wall 60.
  • the canopy member 64 extends inwardly and upwardly at an angle and terminates adjacent inner upper edge 66 of deck 67 of an insulated suspended ceiling.
  • the insulated ceiling has deck 67 suspended from roof 61 by elongated members 68 which can be joined such as by brackets 69 to deck 67 and by brackets 70 to roof 6] or such other means as is suitable.
  • Granular or any other insulation 71 is placed on top of canopy member 64 to a height sufficient to provide the necessary insulation.
  • Insulation 72 of the granular type is also placed on top of deck 67 to thereby insulate the area between the upper edge 66 of canopy member 64.
