Definitions

  • This invention is a new concept for products liq ⁇ uid storage, having protection against pollution as well as fire and explosion.
  • the different liquid prod- ucts are stored in different flexible cushions, kept into an aqueous environment.
  • the product with less den ⁇ sity must be kept into the superior cushion and so suc ⁇ cessively up to the product with the greatest density which is kept into the bottom cushion.
  • the liquid prod- uct volume into each cushion varies from zero until its maximum limit, according to the simple variation of di ⁇ ameter and height of the cushion. Inside each cushion there is only liquid product, without the presence of air, thus eliminating the presence of product vapour, and consequently the loss through evaporation as well as risk of fire and explosions.
  • a variable range of products can be used in the making of the flexible cushions, like rubber, plastic and so on, but it must be chemically resistant to the product contained inside.
  • the shape of the cushions may have every de ⁇ sired form, like circular section, square, rectangular and so on. To simplify this report (as well as the drawings) we shall here show the cushions always with circular section.
  • fig 1 and fig 2 give a global vi ⁇ sion of this new concept of storage, in which fig 1 shows the upper view and fig 2 shows a vertical section through line A-A of the fig 1.
  • - 2 - Fig 1 and fig 2 show the flexible cushions (1), four of them, in which the liquid products are stored.
  • This system can be used with any number of cushions.
  • the cushion (1) is filled with product (2), the bottom of the cushion (1) goes automaticaly down, in ⁇ creasing the height of the cushion (1) , and reducing its diameter and, consequently, increasing its capac ⁇ ity.
  • Fig 1 and fig 2 also show: - the product inlet pipeline (3), with the inlet seal ⁇ ing valve (4) ;
  • Fig 1 and fig 2 also show:
  • a vertical underground tank (8) of circular section To make it sim ⁇ ple it was adopted a vertical underground tank (8) of circular section.
  • the tank however, can have any de ⁇ sired configuration, and can be undeground, semi- underground or aerial;
  • connection water tube (12) which communicates the aqueous environment (7) with the upper aqueous envi ⁇ ronment (10), with its passage valve (13), its exten- sion (25) and the valve (26);
  • Fig. 6 shows detail B of fig. 2 in an amplify ⁇ ing way. In fig. 6 the following details are shown:
  • Fig. 6 also shows the following parts, which, to simplify, were not presented in fig. 1 and fig. 2:
  • the tank (8), the internal bag (16) and the cushions (1) operate as a storage system of triple wall.
  • the aqueous environment (7) will pene ⁇ trate into the draining pipeline (17), being thus imme- diately detected and collected through the draining suction pipeline (18).
  • the flexible cushions (1) can be made and assembled in an unique set, in which the bottom of one cushion is the cover of the below one, as shown on fig. 1 and fig. 2, or in separated cushions, as shown on fig. 8.
  • the system also allows the use of a set of cushions as well as separate cushions, admiting the addition of new cushions, in cases like the coming out of a new product or even the replacement of one cushion for another with greater capacity.
  • the Archimedes effect when the cushions (1) are placed in an aqueous environment (7), the Archimedes effect generates a vertical force (F) - fig. 2 - which acts on them from bottom to top.
  • a vertical force (G) acting from top to bottom due to the own weight of the cushions (1) and of the products (2) , as shown on fig. 7.
  • the cushions (1) must resist not only chemi ⁇ cally to the products (2) stored inside, but also to the traction efforts due to the force (F) when in an aqueous environment (7), or the force (G) in the ab ⁇ sence of the aqueous environment.
  • the traction efforts on the cushions, due to the force (F) or (G) can be great, raising therefore the cost of the cushions.
  • This new concept of storage also admits the breaking up of the forces F or G, through the separa ⁇ tion of the cushions in different sets as shown on fig. 9.
  • Fig. 9 shows a storage system with only two different sets of cushions, each having 3 cushions.
  • the 3 upper cushions are placed in the superior part of the tank, pressed against the tank lid (8.2), due to Ar ⁇ chimedes effect.
  • the 3 inferior cushions are placed in the superior part of the inferior half of the tank, pressed against a false roof (20) that is placed in the middle of the tank, supported by the tank vertical wall (8.1) and by pillars (21) that exist inside the tank.
  • the aqueous environment (7) will then drain to the soil (9), opening automatically the safety valve (14) and making the upper aqueous environment (10) to come down to the aqueous environment (7). If no human action is definitely taken, all the aqueous environment (7) and the upper aqueous environment (10) will flow to the soil (9) , forcing the flexible cushions (1) to go down, due to action of gravity and the non-existence of the Archimedes effect, as shown on fig. 10. The set of the 3 upper cushions will be displaced on the false roof (20) and the set of the 3 inferior cushions will be displaced on the bottom of the tank (8) .
  • This new concept of storage has also the addi ⁇ tional facility of offering greater operational capac ⁇ ity with less physical capacity, for, since the cush ⁇ ions do not have open spaces (spaces with air) there is no therefore, the idle space that exists in the conven ⁇ tional storage systems; they are, so, able to reach their maximum capacity with the most different volumes of each product, as shown on the example on the fig. 3, fig. 4 and fig. 5.
  • This feature allows the reduction of about 35 % of the total physical capacity of the tank (8) , without changing the operational capacity of the system.
  • the position of the valve (4) should be higher than the elevation of the product (2) (due to the Archimedes effect) when occurring the maximum storage of lighter products.
  • the product unloading from the lorry to the cushions (1) through the valve (4) and the product inlet pipe- line (3) may have its outflow reduced. This outflow can be increased with the use of a conventional motor-pump connected to the valve (4) , sucking from the lorry to the cushions.
  • Fig. 11 representing the enlarged C detail of the fig. 2, shows all the components belonging to fig. 2 and adds the following which were not shown on fig. 2, as a way of simplifying that figure:
  • the safety valve (14) will be automatically set in motion, avoid ⁇ ing formation of vacuum inside the tank (8) .
  • This device will allow the supplying Service Station pumps to work without private motor-pumps. In case of an accident with the supplying Service Station pumps, and consequent leakage of product, the same will cease by the closing of the valve (29) or the closing of the valve (26), or the closing of both valves. It is important to point out that the closing of the valve (26) will prevent the entering of water in the aqueous environment (7), and when there is no water entering, there will be no possibility for the product to come out.
  • the aqueous environment (7) will communicate with the upper aqueous environment (10) through the opened valve (13). Always when a certain volume of product is unloaded into the cushions, the same volume of water will auto- matically be displaced to the upper aqueous environment (10), and vice-versa.

Abstract

Nouveau mode de stockage de produits liquides dans des coussins souples immergés dans un milieu aqueux à l'intérieur d'un sac imperméable, et entourés d'un réservoir robuste enterré, à moitié enterré ou aérien, formant ainsi un système de stockage équivalent à un système à trois parois. Ce système assure notamment l'absence d'air, l'absence de vapeurs des produits, et l'absence de pertes dues à l'évaporation, et il exclut toute pollution de l'air, du sol et de la nappe phréatique ainsi que tout risque d'incendie et d'explosion. Le système comporte deux milieux aqueux et l'eau passe automatiquement de l'un des milieux à l'autre chaque fois que l'on introduit des produits dans les coussins ou qu'on les extrait de ceux-ci.
