Description
Title: Device for storing, filling, recirculating, and emptying of liquid products
The present invention relates to a device for storing, filling, recirculating, and emptying of liquid products.
In the chemical industry, toxic and/or hazardous liquid are typically stored in large above-ground vertical storage tanks. In many cases the tanks are placed in tank pit with a bund wall, to mitigate the maximum evaporative area in case of a tank failure, and to avoid further spread of the hazardous liquid (e.g. to mitigate fire from spreading). Above ground storage tanks (AST) may store and contain fuels or other chemicals at industrial facilities such as airports, refineries, depots, factories etc. One concern with such tanks is the possibility that the tank may develop a leak which is not readily discernible through normal methods of inventory control or visual inspection.
Significant environmental concerns arise with leaks which are relatively minor when viewed over a short period of time. Such leaks, when left undetected and unrepaired, often result in very substantial leakage over a long period of time. The problem of leak detection becomes even more acute as the size of the storage tank increases since, as may be envisioned, minor leakage from such tanks will cause only a small change in the level of the liquid in storage. This is particularly true in tanks greater than about 2 meter in diameter. Also, in above-ground tanks, changes in ambient conditions, such as temperature and wind, can affect the level of the liquid in the tank.
It is also known that small tanks are sometimes placed in special collector trays of steel concrete or steel construction. A disadvantage is that any leakage in these collector tanks goes entirely unnoticed so that in the event of a leakage in the tank there is no adequate protection to prevent the liquid from seeping into the soil. It is also known to provide a second steel sheet bottom, mainly in domestic tanks for fuel oil, so that, in the event of a leakage of the first bottom, the second bottom prevents the liquid from spilling out of the tank until the second bottom also springs a leak.

German Gebrauchsmuster DE 17 75 987 relates to a collecting tray on containers for flammable liquids, wherein the collecting tray is provided with a water drain pipe which has a pipe section forming the highest point of the water drain pipe, which is arranged below the upper edge of the collecting tray and above the inlet opening of the pipe located in the collecting tray. Such collecting tray serves to collect the liquid running down the outer casing when escaping from the container due to leaks, breaks or other damage.
There is international legislation developed esp. after the Buncefield incident, wherein a tank at the Buncefield oil storage depot was being filled with petrol. The tank was filled up completely, the petrol overflowed through vents at the top, and formed a vapour cloud near ground level, which ignited and exploded. National norms in The
Netherlands to describe the storage of hazardous (incl. flammable) and/or toxic liquids are disclosed in for example PGS-29. PGS 29 applies to installations with at least one vertical cylindrical above-ground steel tank, the bottom of which rests on a foundation.
The directive applies during the entire life phase of the tank.
An object of the present invention is to provide an environmentally safe and fire-safe construction for storing, filling, recirculating, and emptying of liquid products.
The present invention thus relates to a device for storing, filling, recirculating and emptying of liquid products, the device comprising a primary tank and at least one secondary tank, wherein the at least one secondary tank is located within the primary tank, the secondary tank comprises a secondary liquid, wherein the annular space between the primary tank and the at least one secondary tank is filled with a primary liquid, wherein the primary liquid present in the annular space functions as a storage medium for any leakage of secondary liquid from the at least one secondary tank into the primary liquid present in the annular space.
On basis of the above device the object of the present invention is achieved.
The present inventors have found that hazards are now managed in a more intrinsic safe way. A possible failure of the secondary tank, for example by corrosion, production flaw, external influences will have less severe impact because the secondary liquid is diluted, and optionally neutralized in the primary liquid present in the annular space between the primary tank and the at least one secondary tank. In a situation where the secondary liquid will not be dissolved in the primary liquid, the secondary liquid having a higher density than the primary liquid will sink and thus there will be a kind of a “shield” created for the secondary liquid.
The term “at least one secondary tank” includes embodiments wherein two or more secondary tanks are located within the primary tank. In the event of a leakage of the secondary tank the secondary liquid is being diluted in the primary liquid resulting in a much lower vapour pressure, leading to much lower safety contours.
In an example the at least one secondary tank is made of a flexible material that is resistant to the contents of the at least one secondary tank.
In an example the at least one secondary tank is made of a polymer material, chosen from the group of polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), polyphenylene oxide (PPO), polysulfone (PSU), polyether ether ketone (PEEK), polyimide (Pl) and epoxy resins, or combinations thereof.
In an example the primary tank is made of a material chosen from the group steel, concrete, fiberglass reinforced plastic (FRP), polyethylene (PE) and polypropylene (PP), or combinations thereof, wherein especially the material is coated or provided with a liner to improve their chemical resistance. Examples of materials for a liner are stainless steel liner, polyvinyl chloride (PVC) liner, polyurethane (PU) liner, rubber liner, such as EPDM (ethylene propylene diene monomer), polyethylene (PE) liner, polyvinylidene fluoride (PVDF) liner, polytetrafluoroethylene (PTFE) liner, perfluoroalkoxy alkanes (PFA) liner and butyl liners, especially PE and PVDF. These liner materials offer high strength, corrosion and leakage resistance, durability and are suitable for storing various liquids, including acids, alkali, and petroleum products.
The primary tank can be made of low cost materials because the primary tank will only be in contact with the primary liquid, i.e. a normal non-toxic non-hazardous liquid. The primary tank is only made resistant for the event of a leakage of the secondary tank, for exposure of the secondary liquid that will come into contact with the primary liquid.
In an example the density of the secondary liquid is higher than the density of the primary liquid. This will have the effect that the secondary tank will stay in place within the primary tank.
In an example the secondary liquid is a toxic and hazardous liquid, wherein the toxic and hazardous liquid originates from a flow battery, especially a hydrogen- bromine flow battery, more especially an aqueous mixture of HBr and Br.
In an example the primary liquid comprises water, wherein the primary liquid 5 may further comprise one or more additives for neutralizing the secondary liquid.
These additives may be added to the primary liquid in case of a leakage from the secondary tank, i.e. in the event the secondary liquid will contact the primary liquid in the annular space.
In an example the primary tank is open to the atmosphere.
In an example the primary tank is provided with a cover to prevent evaporation of the primary liquid to the atmosphere. In addition, such a cover will also have a positive effect on the heat losses of the primary liquid to the atmosphere.
The primary liquid can also be used to regulate the temperature of the secondary liquid. For example, the temperature of the primary liquid can be controlled via an external cooling-heating circuit and the primary liquid present in the annular space will transfer its heat energy via heat transmission to the secondary liquid present in the secondary tank. According to such a system the temperature of the secondary liquid present in the secondary tank can be indirectly, i.e. via a heat transfer mechanism, increased or decreased.
In an example both the secondary tank and the primary tank are under pressure for releasing any vapours from the secondary tank and the primary tank to a pressure system.
In an example the secondary tank is closed to the atmosphere.
In an example the secondary tank is provided with means for releasing any vapours from the secondary tank.
In an example the secondary tank is provided with a wet scrubber, wherein any vapours released from the secondary tank are fed to the wet scrubber and a wash liquid from the wet scrubber is returned to the secondary tank. In a wet scrubber a wash liquid is contacted with the vapours released from the secondary tank and contaminants from the vapours are washed out, collected in the wash liquid, and subsequently returned to the secondary tank. The result is a vapor stream that is depleted from any contaminants. Such an embodiment can be implemented in the situation of the cross-over of a flow battery construction as shown in WO 2023/121454 in the name of the present applicants.
In an example the at least one secondary tank is provided with one or more connecting means for fastening the at least one secondary tank to the primary tank.
In an embodiment where the secondary tank is made from a polymer as mentioned above, the secondary tank is attached with connecting means to the primary tank where the annular space below, around and above the secondary tank will be ensured.
In an example the at least one secondary tank is provided with means for storing, filling, recirculating, and emptying of secondary liquid of the at least one secondary tank.
The present construction of a secondary tank located within the primary tank will have the benefit that now a group of construction materials for the secondary tank will become available, but these materials have not been proven to be suitable to produce large scale above ground tanks from. Examples of such a group of construction materials having a superior chemical resistance towards certain chemical components are fluoropolymers for storage of acidic and oxidative liquids, for example hydrobromic acid with bromine.
In an example where the secondary liquid is a toxic and hazardous liquid, e.g. a liquid originating from a hydrogen-bromine flow battery, especially an aqueous mixture of HBr and Br, the inner tanks or bags, namely the secondary tank(s), are made of material with high chemical resistance to HBr and Br2. However, bromine (in a form of Bry) may diffuse/permeate through the material of the secondary tank. This should normally not be an issue, but if the secondary tank were to rest directly on the bottom of the primary tank, bromine could accumulate between the primary tank and the secondary tank. Such accumulation may lead to corrosion of the primary tank. In order to prevent such accumulation the inventors found a solution for this. In an embodiment a flow of the primary liquid in a space between the primary tank and the secondary tank is ensured by the application of open structures on the bottom of the primary tank. The result of these open structures is that water as an example of the primary liquid may flow through the space under the secondary tank, i.e. the space between the primary tank and the secondary tank. Such flow of primary liquid prevents a build-up of bromine and prevents corrosion of the primary tank, too. Traces of bromine in the primary liquid will be measured and the primary liquid can be replaced by a new amount of primary liquid, if needed. An example of an open structure is a grid made of PE, PVC or PVDF. Such a grid is provided with sufficient open spaces for the primary liquid to flow underneath the secondary tank.
In an example a grid is positioned in an area between the underside of the at least one secondary tank and the bottom of the primary tank, the grid being provided with open spaces enabling a flow of the primary liquid in that area.

Secondary tanks 21, 39, 40 and 41 comprise a secondary liquid 23, 45, 46 and 47, wherein the space between primary tank 24 and secondary tanks 21, 39, 40 and 41 is filled with a primary liquid 44, wherein primary liquid 44 present in the annular space functions as a storage medium for any leakage of secondary liquid 23, 45, 46 and 47 from secondary tanks 21, 39, 40 and 41 into primary liquid 44 present in the annular space. Primary tank 24 is covered with tank cover 42. Liquid 25 from one or more production units is sent to each of secondary tanks 21, 39, 40 and 41, wherein in this figure only the connection with secondary tank 41 is shown. Each of secondary tanks 21, 39, 40 and 41 is also connected to one or more external product units 26, wherein in this figure only the connection with secondary tank 41 is shown. An exchange between a liquid and vapor stream 35, 36, 37 and 38 is shown for secondary tanks 21, 39, 40 and 4, respectively. Stream 35, 36, 37 and 38 is sent to scrubber 34, 33, 32, 31, respectively. Each scrubber 34, 33, 32, 31 is provided with scrubber liquid 30, 29, 28, 27, respectively. From each scrubber 34, 33, 32, 31 a stream depleted from contaminants is collected and sent for further processing as stream 43. Reference number 22 is a grid provided with open spaces for primary liquid 44 to flow underneath tanks 21, 39, 40 and 41. Grid 22 can consist of individual separate grids positioned between the underside of tanks 21, 39, 40 and 41 the bottom of primary tank 24.
An example of a secondary liquid is a mixture of HBr and Hz. And example of a secondary tank is an electrolyte storage. From Figure 2 one will recognize that each secondary tank is connected to a separate process unit, i.e. the scrubber. Each secondary tank has a subsystem with its own scrubber to remove and purify the hydrogen gas that accumulates in the secondary tank. The scrubber liquid also comes from the same unit and returns to the secondary tank. The secondary liquid, i.e. electrolyte with HBr/Br2 also circulates over this unit. The hydrogen return can be combined since the hydrogen storage of various process units may also be shared.
