SPECIFICATION
Portable Fuel Storage and Dispensing Tank
This invention concerns a portable fuel storage and dispensing tank, and more particularly relates to an above-ground tank for petroleum products at a station providing a dispensing service for motor vehicles.
Traditionally, in the United Kingdom, storage of petroleum products at dispensing points is effected in tanks mounted beneath ground level, and only on very rare occasions, for instance temporary sites associated with an itinerant exhibition or on sites only used spasmodically, has aboveground storage been contemplated, mainly because of the hazard presented by such installations.
Modern day requirements, resulting from extension of the motoring population, the need for stations in remote parts, the increasing tendency to provide unmanned stations, and the temporary location of sites resulting from local conditions, such as diversion during large-scale construction or repair works, is likely to result in an increased demand for portable fuel storage and dispensing tanks. Local authorities are naturally and rightly concerned that sites embodying such above-ground tanks should have a high safety factor and this invention relates to a tank which it is believed exhibits this requirement.
According to the present invention a portable fuel storage and dispensing tank comprises a double-skin container rigidly mounted within an outer protective housing, the two skins of the container being spaced from one another, with an inert insulating material filling the space between the two skins, and the protective housing embodying reinforcing members to afford mechanical protection to the containers.
Preferably the outer protective housing is carried on a supporting raft adapted for mounting on a suitable foundation laid at ground level.
Conveniently, if it is desired to store and dispense different grades of fuel, the inner of the two containers is divided into an appropriate number of compartments by one or more membranes, each compartment being provided with its own filling, dispensing and venting means. One or more pumps and auxiliary equipment may be accommodated within the outer housing, in a chamber constructed with appropriate safety features.
The invention will now be further described by way of example with reference to the accompanying drawings, in which:—
Figure 1 is a side elevation, partly broken away for ease of illustration of a tank according to the present invention;
Figure 2 is a corresponding plan view;
Figure 3 is a vertical section taken along the line III—III of Figure 1, and
Figure 4 is a schematic flow diagram applicable to the tank of Figures 1 to 3.
As shown by Figures 1 and 2 a fuel storage and dispensing tank comprises a fuel container 10
formed by an inner skin 12 defining the actual fuel storage volume and an outer skin 14 spaced from skin 12. The intervening space 16 is filled with an inert insulating material, such as "Perlite (R.T.M.)". In the illustrated embodiment the container 10 is divided centrally by a membrane 18 to provide two separate compartments 20 and 22 intended to contain differently rated fuels, i.e. one of a higher octane than the other. Obviously, by the provision of additional membranes or dividing walls, any desired number of separate compartments may be obtained. Both skins 12 and 14 are constructed from mild steel plate, and preferably skin 14 is thicker, possibly even twice as thick, as skin 12. For instance skid 12 may be manufactured from 6 mm plate and skin 14 from 12 mm plate with a spacing of 25 mm between for the inert insulating material.
Spaced from, and surrounding fuel container 10 is an outer protective housing 24 suitably braced with reinforcing members 26. Housing 24 may be prefabricated from mild steel plate, for instance 6 mm plate. Container 10 is carried within housing 24 on mild steel cradles 28. Provision is made at one end of housing 24 for a chamber 30 to accommodate pumping and other equipment and access to this chamber is by means of lockable doors 32. This chamber 30 can also house fill and drain connections, fire extinguishes and an earthing connection. Housing 24 may be provided with a protective and/or decorative canopy 34. Valved drains 36 may be provided at each end of housing 24 and the whole unit may be carried on a supporting raft 38 resting on suitable foundations. The unit can be transported as a module to any suitably prepared site.
Access to container 10 is through one of two lockable covers 40 in the roof of housing 24 which when opened reveal manhole tops 42 associated one with each fuel compartment 20 and 22 and lifting eyes 44. Airvents are provided in housing 24 to reduced internal condensation.
Conveniently housing 24 is provided with a motorway type crash barrier (not shown) around it to obviate possiblity of damage in the event of a vehicle colliding with it.
The manholes 42 may each incorporate fill and drain connections as well as delivery, dip and vent. A spare connection may also be embodied.
A typical flow diagram is shown in Figure 4 wherein compartments 20 and 22 are shown schematically, dispensing from compartment 20 being by way of pipe 46 and from compartment 22 by way of pipe 48. Each of these pipes has a slam shut valve 50 operated by a fusible link (against fire hazard) and a magnetic valve 52 (to prevent syphoning) energised to open. Fuel is supplied from bulk vehicle unloading point 54 through a screw down non-return valve 56 and a pump 58 (in chamber 30) to a 3-way valve 60 fed through a non-return valve 62. Operation of valve 60 determines whether fuel fed to the tank goes into compartment 20 by way of pipe 64 or to compartment 22 by way of pipe 66. Both pipes

64 and 66 have plugged drain connections 68. Vent pipes 70 from each fuel compartment terminate in pressure vacuum relief valves 72 (liquid shut out) because these vent lines must 5 pass vapour only and shut off it liquid fuel attempts to travel along them, for instance as a result of overfilling of either compartment.
It is a general requirement that any container for dangerous liquids shall be mounted within or 10 surrounded by a bund, that is an outer retaining element which, in the event of damage to the container resulting in leakage of the liquid therefrom, is capable of retaining the maximum contents of the container without spillage beyond 15 the boundaries of the bund. In the construction described, the bund is formed by outer protective housing 24 which is internally sealed in its lower half, apart from drains 36, to a height such that the internal volume of that lower half is 20 sufficiently great to retain the entire contents of both compartments of container 10 in the event of rupture or other damage thereto. In other words the internal volume of housing 24, up to say the lower edge of doors 32, is in excess of the 25 maximum capacity of a container 10 (more specifically of the compartments 20 and 22 defined by inner skin 14).
