Abstract

There is described a new concept for liquid products storage, comprising flexible cushions in which the products are stored, immersed in an aqueous environment inside an impermeable bag, and surrounded by a steady tank, which may be buried, semi-buried or aerial, forming thus a storage system equivalent to a triple wall system. The system emphasizes the aspects of absence of air, absence of product vapour, absence of loss through evaporation, no pollution of the air, soil and water table as well as the total impossibility of fire and explosion. The system presents two aqueous environments, with automatic displacement of water from one environment to the other, every time the products are added or removed from the cushions.

Description

ECOLOGICAL STORAGE OF LIQUIDS 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.
This new concept is meant to be used in any product storage system and to any volume. In order to simplify the exposition and to make it easily under¬ stood, we shall be taking as an example (also for the drawings) the storage of alcohol and liquid products of petroleum in Service Stations.
On the drawings that go along with and are part of this report, 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. When 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) ;
- the product outlet pipeline (5), for the Service Sta¬ tion supplying pumps;
- the flexible link (6) of the cushion (1) with the inlet pipeline (3) and the outlet pipeline (5).
For each cushion (1) there must be an inlet pipeline (3), an outlet pipeline (5) and a flexible link (6). To make it simple fig 1 and fig 2 are showing only one inlet pipeline (3), one outlet pipeline (5) and one flexible link (6), relating to only one cushion
(1).
Fig 1 and fig 2 also show:
- the aqueous environment (7) where the cushions (1) are kept; - the soil (9) and the underground tank (8), which contains the aqueous environment (7). 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;
- the upper aqueous environment (10), in fig 2 situ¬ ated over the tank (8) ;
- the bundwall (11), which holds the upper aqueous en¬ vironment (10). To simplify it was adopted a conven- tional earth bundwall. Its geometrical configuration, however, can be anyone. It can even be located in an- other place instead of over the tank (8);
- the 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);
- the safety valve (14) of the tank (8), to be used in case of vacuum occurrence;
- the suction pipeline (15) to evacuation of product (2) , in case of a rupture on the cushion (1) . As the products get into the cushions (1), they will be increasing their space in the tank (8), automatically pushing same volume from the aqueous en¬ vironment (7) to the upper aqueous environment (10), through the connection water tube (12) and its passing valve (13). Inverse process occurs when products (2) are being removed from the cushions (1) .
When all the cushions (1) are filled with their maximum storing capacity, they will be occupying the total vertical height of the tank (8) and the bottom of the lower cushion (1) will be touching the bottom of the tank (8), as shown on fig. 3, fig. 4 and fig. 5.
When the cushions (1) are filled with prod¬ ucts (2) they are pushed up (F) due to the Archimedes effect, since in the case of this description (storage in Service Station) the products (alcohol, gasoline and diesel) are of lower densities than the aqueous environment.
Fig. 6 shows detail B of fig. 2 in an amplify¬ ing way. In fig. 6 the following details are shown:
- the vertical wall (8.1) of the tank (8);
- the tank lid (8.2);
- the flexible cushion (1);
- the products (2) ; - the aqueous environment (7);
- the upper aqueous environment (10); - the soil (9) .
Fig. 6 also shows the following parts, which, to simplify, were not presented in fig. 1 and fig. 2:
- the internal tank bag (16), covering the whole inte- rior of the tank (8) ;
- the draining pipeline (17) made of a duct with holes, installed inside the tank (8) and placed between the vertical wall (8.1) of the tank (8) and the internal tank bag (16) ; - the draining suction pipeline (18), linked to the draining pipeline (17) with its valve (19) in the ex¬ ternal border;
- the impermeable blanket (31) of the upper aqueous en¬ vironment (10). The tank (8), the internal bag (16) and the cushions (1) operate as a storage system of triple wall. In case of an incidental disruption of the inter¬ nal bag (16), 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).
In case of an incidental product (2) leakage from the flexible cushion (1), the spilled product, which is less dense than the aqueous environment, will rise up to reach the top of the internal bag (16) and will be naturally conducted to the suction pipeline (15) mouth - shown on fig. 2 - due to a small slope on the tank lid (8.2). The product incidentally leaked will be then retired through the suction pipeline (15). This new storage concept will warrant there¬ fore:
- absence of losses through evaporation, once there is no contact between the products and the air;
- no possibility of air, soil or water table pollution, on account of this being a system with no external drainage communication, with no vapour of products and also being a system in which can be easily re¬ tired in case of a spillage; - no possibility of fire and explosion, since there is no vapour from the products, due to the absence of air in the system.
In the hypothesis of a leakage through the in¬ ternal bag (16), without any human action to prevent it (through the draining suction pipeline (18)) - fig. 6 - and also followed by a leakage through the tank wall, the aqueous environment (7) will drain to the soil (9), opening automatically the safety valve (14) - fig. 1 and fig. 2 - making the upper aqueous environ¬ ment (10) to come down to the aqueous environment (7). In case no human action is definitely taken, all the aqueous environment (7) and the upper aqueous environ¬ ment (10) will then flow to the soil (9), forcing the flexible cushions (1) (due to the gravity action and to the non-existence of the Archimedes effect anymore) to change their position in the upper part of the tank (8), for the inferior part of the tank, as shown on fig. 7.
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.
As previously said, 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. In case of a leakage of the whole aqueous environment (7) and the whole up- per aqueous environment (10), there will be 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. Depending on the capacity, diameter and maximum height of the cushions, 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. In the hypothesis of a leakage through the in¬ ternal bag (16), without any human action to prevent it - fig. 6 - and also followed by a leakage through the tank walls, 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.
Returning to fig. 2, 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. In a situation of too many light products, and too much stored product, 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:
- water motor-pump (22);
- valve (23); - delivery pipeline (24) from the water pump (22)
- delivery pipeline (27) from the water tank; - suction motor-pump (28);
- valve (29) and valve (30).
With the starting of the motor-pump (22), the opening of the valve (23) and the closing of the valve (13) and the valve (26), it is possible to withdraw the aqueous environment (7) from inside the tank (8) and pump it to the water tank located, for example, on the roof of the Service Station office. With this proc¬ ess, a depression is created inside the tank (8) and the product will be sucked from the lorry through the product inlet pipeline (3), with the same outflow as the one of the water-pump (22). If at any moment, for any reason, the unloading product outflow from the lorry becomes lower than the water outflow from the aqueous environment (7) inside the tank (8), the safety valve (14) will be automatically set in motion, avoid¬ ing formation of vacuum inside the tank (8) .
By closing valves (13) (23) and by opening val¬ ves (26) (29), the water from the water tank above the office, passing through the delivery pipeline (27), will fall in the extension (25) of the water connecting tube (12), so pressurising the aqueous environment (7) of the tank (8), thus increasing the outflow of the product (2) from the cushions (1) to the supplying pumps of the Service Station, through the product out¬ let pipeline (5).
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.
On a normal process of operation, and without the utilization of water motor-pump (22) and also with¬ out the utilization of water delivery pipeline from the water tank above the office of the Service station, 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.
As it was previously described, in case of product (2) leakage from the cushions (1) , since the product (2) is lighter than the aqueous environment (7), it will go up to the tank lid (8.2) so that it can be sucked by the suction motor-pump (28) through the suction pipeline (15).
