Definitions

  • tanks of the kind described Such tanks will be referred to hereinafter as "tanks of the kind described”.
  • a tank of the kind described comprising continuous skirt means extending downwardly withrespect to and in the region of the periphery of the base of the inner container, and continuous flange means extending upwardly from the base of the outer container and radially within the skirt means, the free edge of the skirt means being lower than the free edge of the flange means to provide a vapour lock between the base insulation and the space between the inner and outer walls of the tank in the event of a leak from the wall of the inner container to limit the amount of liquid reaching the base insulation.
  • the tank may be cylindrical and the skirt means and flange means annular.
  • the skirt means may be of a diameter greater than the diameter of the inner container.
  • a bedding layer 23 of sand Beneath the inner container base 12 is a bedding layer 23 of sand and beneath the bedding layer of sand 23 is a barrier sheet 24 of steel having a skirt 25 extending downwardly and continuously around the periphery of the barrier sheet 24.
  • a base insulation layer 26' of foamed glass in block form, or other suitable insulation material surrounded by a'ring of lightweight insulating concrete blocks 26 and, radially inwardly of the skirt 25, a flange 27 extends continuously and upwardly from the vapour barrier 15.
  • the vapour barrier 15 and the flange 27 are conveniently of steel so that the flange 27 can be secured to the vapour barrier by welding although other means may be used.
  • the flange 27 extends above the base of the skirt 25 with the result that, if a leak occurs in the wall 11 of the inner container causing liquid to occupy the space between the wall 11 and the vapour barrier 15, when liquid begins to permeate the base insulation it is warmed and produces a vapour pressure which causes the combination of the skirt 25 and flange 27 to act as a vapour lock to prevent further entry of liquid from the space between the wall 11 and the vapour barrier 15 into the base insulation. In this way, wide spread contamination of the base insulation by the liquid is prevented.
  • a layer 28 of wall foam insulation is provided on the inside of the vapour barrier 15.
  • a further advantage of the vapour lock arrangement is that since the liquid level in the inner container would always be greater or equal to the liquid in the annular space between the wall 11 and the vapour barrier 15, there would be no danger of vapour pressure in the base insulation lifting the inner container base 12. The vapour pressure beneath the barrier 24 cannot exceed the pressure caused by liquid contained in the inner container 11.
  • Figure 3 shows a bracket arrangement for securing the inner container to the foundations.
  • a bolt 29 is set in the foundations and passes through the vapour barrier 15 and the barrier sheet 24, sealing welds being made between the bolt 29 and the vapour barrier and barrier sheet.
  • a nut 30 applies pressure to a flange 31 secured to the inner container to hold down the inner container for example to resist forces from events such as earthquakes.
  • Figure 4 illustrates a base edge detail of a modified tank of the type shown in Figures 1, 2 and 3.
  • barrier sheet 24 1 extending further out beyond the periphery of the inner container than was the case in the embodiment of Figures 1 to 3 and the liquid barrier is extended close to outer containment wall 14. This arrangement reduces the area over the base slab that cold temperatures could apply and could ease design on the concrete beneath the outer containment wall 14 .
  • FIG. 8 A further embodiment of a tank, generally indicated at 60, is shown in Figure 8.
  • the tank 60 has an inner container 61 conveniently of steel with a dome roof.
  • An insulation layer 62 covers the wall and roof of the inner container 61.
  • the inner container 61 is seated, in a similar way to the embodiment of Figure 3, on a base insulation layer 63, suitably of foamed glass with a barrier 64 of steel or other suitable material between the base insulation 63 and the base of inner container 61.
  • the barrier 64 has a downturned peripheral skirt 65 and a flange 66 extends from outer base 67, the skirt 65 and flange 66 providing a vapour lock in the way hereinbefore described.
  • a bund wall 68 extends around the outside of the inner container 61 to prevent widespread liquid spillage in the event of a leak.
