Definitions

  • the present invention relates to a tank for liquefied petroleum gas, consisting of a clean air tank says resting on feet supported on a base.
  • Air tanks especially tanks large volume sphericals are used for the storage of liquefied petroleum gas (also known as G.P.L.). These tanks have a number of disadvantages, too are they replaced wherever possible by tanks under an earth slope. However, these tanks under slopes have a significantly lower capacity than that of spheres and require certain deviations from controls periodicals required.
  • liquefied petroleum gas also known as G.P.L.
  • the spherical reservoir is the solution ideal in terms of reducing floor space and the cost of implementation and maintenance.
  • the present invention aims to allow the production of aerial tanks, in particular for liquefied gas protected.
  • the invention relates to a tank of the type defined above, characterized in that it comprises an envelope comprising a skirt and a blanket forming a spacing containment filled with an inert atmosphere.
  • the protective cover of the aerial tank provides protection equivalent to that which a slope, i.e. equivalent protection of one meter embankment thickness where the thickness is the smallest. It provides access to the entire tank, which is not not possible in the case of a tank under slope.
  • the invention allows to build new tanks, meeting the regulations or to bring existing tanks into conformity.
  • the footprint of the installations according to the invention by comparison with those of tanks under slope, is much lower and better suited for sites with high density of occupation. Finally, the overall cost of such tank is significantly lower than that of a tank under Bank.
  • the invention also makes it possible to conserve the tanks existing aerials without having to dismantle or dismantle them replace with new tanks, while having after putting in place of the protective casing, a compliant installation to regulations. This represents a considerable saving.
  • the invention relates to a tank large dimensions, intended for the storage of petroleum gas liquefied.
  • This tank consists of the spherical tank aerial 1 proper, carried by feet 2 resting on a base 12 formed, for example, of a concrete ring.
  • This tank 1 with its feet 2 is surrounded by a reinforced concrete envelope composed of a cylindrical skirt 3 occupying much of the height of tank 1 and ending at its upper edge by an annular tie rod 4 receiving a dome 5 formed of radiating ribs 51 supported on the tie rod annular 4.
  • the top of the dome 5 is occupied by a skylight 6 also serving as support for the corresponding ends ribs 51.
  • This skylight 6 forming a manhole is closed by a cover 7.
  • Figure 2 shows in perspective the structure of the cylindrical skirt 3, of the annular tie rod 4 and the shape of the ribs 51 of the dome, as well as that of the skylight 6.
  • the envelope formed by the skirt 3 and the dome 5 is at a certain distance from the contour of the reservoir 1 and its feet 2. This distance is that made necessary for the installation of formwork elements used for manufacturing skirt 3, tie rod 4 and dome 5.
  • the skirt 3 has an access door watertight 8 provided with a porthole 9 and preceded by an airlock to allow access to the interior of the containment without deteriorate inerting.
  • the enclosure delimited by the reinforced concrete envelope around the spherical tank 1 contains an inert atmosphere, for example of N 2 or CO 2 gas.
  • This enclosure is monitored by monitoring equipment. control consisting of a temperature detector 10 and a detector 11 connected to a control unit 60. Other monitoring and control equipment is constituted by a low level detector 13, of liquid, of a gas detector 14 and a low level oxygen detector, 15. The detectors, low, are supplemented by a detector 16 of high level and a high level oxygen detector 17.
  • Low and high liquid level detectors detect a possible leak of liquefied gas inside the containment.
  • valve depressurization 20 In the upper part, where the skylight is located 6 constituting a manhole, is a valve depressurization 20. This valve is remotely controlled by from station 60. There is also a calibration valve of sphere 21.
  • the containment itself is provided with upper part of a pressure relief valve 30 and a valve depressurization 31.
  • the spherical tank has a delivery valve 22 connected to the outside by a pipe 23. This delivery valve extracts liquefied gas of the tank.
  • the bottom of the enclosure has a low point 40 in which the end 41 arrives a pumping line 42 for pumping the liquid from leakage possibly accumulated inside the enclosure.
  • This pumping line 42 is connected to a pump 43.
  • the control station 12 which receives the various monitoring and control information, acts on a central blanket 61 which supplies the inert gas inside the enclosure as shown schematically in line 62.
  • the reservoir according to the invention is carried out in the in the case of new equipment, by construction and implementation place of the spherical tank 1 then the installation of the envelope.
  • the cylindrical skirt 3 is preferably constructed with a sliding formwork allowing the work to be poured practically continuously.
  • the skirt 3 is secured to the crown of the existing base 12, by means of a resin mortar without shrinkage.
  • the annular tie rod 4 is made using a formwork particular analogous to slippery or climbing formwork.
  • the ribs 51 of the dome are prefabricated. These ribs are self-supporting. They are keyed in the tie ring 4 and skylight 6.
  • the ribs 51 receive prefabricated slabs which are installed on the ribs.
  • the skylight 6 is cast on site so as to key all the radiating ribs 51.
  • the formwork used to make the skylight 6 can rest on top of the spherical tank 1.
  • the skylight 6 leaves in its center a manhole for access to the equipment located on top of the sphere.
  • the interior of the envelope formed by the skirt 3, the ring rod 4 and dome 5 with skylight 6, can be coated with a paint ensuring or completing the seal.
  • the assembly thus produced constitutes protection equivalent to protection under an earth slope with a thickness 1 meter, against projectiles and fire.
  • the envelope helps contain any leaks gas G.P.L. in the event of overfilling by overfilling of the tank or of a rupture of a tapping at the base of the tank for liquid phase or pipe leak.
  • Confined gas can be recovered in liquid phase through piping 41, 42 and pump 43 to be transferred to other storage means.
  • the space inside the envelope is made inert by introducing and maintaining an inert gas such as CO 2 or N 2 .
  • This inert atmosphere is continuously monitored by measuring the oxygen content.
  • This inerting system operates and is controlled automatically by the control station 60 acting on the inerting station 61.
