Abstract
There is provided a liquid containment system that includes a flexible balloon bladder having a holding capacity of holding at least 300 gallons of liquid. The bladder has at least one opening through which liquids are pumped into or out of the bladder. A support structure surrounds and provides lateral support to the bladder.
Description
- There is described a liquid containment system, this system was developed for use in the oil industry for holding large volumes of water required for a process known as “fracing,” but it will be appreciated it could be used for other applications.
- Canadian Patent Application No. 2,756,305 (Hindbo) entitled “Modular Enclosure System” describes an enclosure that can be rapidly deployed at remote sites. In the oil industry, liners are supported by the walls of the enclosure for liquid containment. There will now be described an alternative liquid containment system.
- There is provided a liquid containment system that includes at least one flexible balloon bladder having a holding capacity of at least 300 gallons of liquid. The at least one bladder has at least one opening through which liquids are pumped into or out of the at least one bladder. A support structure surrounds and provides lateral support to the bladder.
- Consideration was given to the use of large bladders for liquid containment and, at first, it appeared that the idea was unworkable. The reason for this is that as a height of a bladder increases the hydrostatic pressure of the liquid column increases and the bladder becomes increasingly unstable. The liquid containment system, described above, overcomes the inherent instability of the large bladders by providing a surrounding support structure. The term “large” can be a relative term. In the context of the types of applications intended, the bladder should be considered “large” when it has a holding capacity of at least 300 gallons of liquid. To provide a better indication as to actual size, the liquid containment system currently under construction has a circular support structure with a diameter of 72 feet, a height of 12 feet and a holding capacity of 792,500 gallons. It will be appreciated that the support structure need not be circular and could be made multi-sided, most likely square or rectangular.
- Once the basic concept of the liquid containment system was developed, problems of transport to remote sites had to be addressed. For transport, a plurality of panels are transported in a disassembled state and then assembled on site to form the support structure and the bladder is transportable in a folded state on a skid. It is preferred that the skid have sidewalls which enclose the skid to form a shipping container for transport. The sidewalls are movable or removable on site to facilitate access to the bladder. Preferably, the sidewalls are hinged to the skid and can simply be folded down flat.
- A second problem that had to be addressed was ease of access to the contents of the bladder. For this purpose, at least one conduit extends externally of the support structure for making a fluid flow connection with the bladder. With the skid being used to transport the bladder, it was realized that the at least one conduit could be incorporated into the skid. According to this aspect of the preferred embodiment, the skid has a first portion and a second portion. Then at least one conduit extends through the skid with a first connection at a first end of the at least one conduit positioned in the first portion and a second connection at a second end of the at least one conduit positioned in the second portion. During installation, the skid is positioned underlying at least one of the plurality of panels of the support structure with the first portion of the skid positioned within the enclosure and the second portion of the skid positioned outside the enclosure. This enables the bladder to be connected to the first connection with the second connection being positioned externally of the support structure for making a fluid connection with the bladder.
- These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein:

reference numeral 10, will now be described with reference toFIGS. 1-6 h. An alternative embodiment, generally identified byreference numeral 100, will be described with respect toFIG. 7 throughFIG. 10 . - Referring to
FIG. 1 ,liquid containment system 10 includes aflexible balloon bladder 12. This is a “large” bladder that has a holding capacity of at least 300 gallons of liquid.Bladder 12 has four openings through which liquids are pumped into or out ofbladder 12. The four opening are not shown in this view and will be hereinafter described. Referring toFIG. 1 , a support structure, generally indicated byreference numeral 16, surrounds and provides lateral support tobladder 12.Support structure 16 has a diameter of 72 feet, a height of 12 feet and a holding capacity of 792,500 gallons. - Referring to
FIG. 2 ,support structure 16 was developed with a view to movingliquid containment system 10 to remote sites. For transport, a plurality ofpanels 18 are transported in a disassembled state and then assembled on site to formsupport structure 16. The manner of securingpanels 18 together to form an enclosure is known and will, therefore, not be further described. Referring toFIG. 6 h,bladder 12 is transportable in a folded state on askid 20. Referring toFIG. 5 , it is preferred that skid 20 havesidewalls 22 which encloseskid 20 to form a shipping container for transport.

Referring toFIGS. 3 and 5 , withskid 20 being used to transportbladder 12, it was realized thatconduit skid 20. Althoughskid 20 is illustrated inFIGS. 3 and 5 withoutbladder 12 being shown, it must be understood that it is intended that bladder be secured with adhesive to skid 20, so it is not removable. Referring toFIG. 4 ,skid 20 has afirst portion 32 to which a portion ofbladder 12 is secured and asecond portion 34 which does not have any portion ofbladder 12 secured to it. Each ofconduit first end second end conduit skid 20.Bladder 12 has four openings through which fluids can pass, identified byfirst connection box 36,second connection box 38,third connection box 40 andfourth connection box 42.First connection box 38 connectsfirst end 24 a ofconduit 24 withbladder 12 and has afirst extension line 44 that extends intobladder 12.Second connection box 40 connectsfirst end 26 a ofconduit 26 withbladder 12 and has asecond extension line 46 that extends intobladder 12.Third connection box 42 connectsfirst end 28 a ofconduit 28 withbladder 12.Fourth connection box 42 connectsfirst end 30 a ofconduit 30 withbladder 12. Referring toFIGS. 3 and 5 , each of second ends 24 b, 26 b, 28 b, and 30 b ofconduit connection manifolds FIG. 4 ,first end conduit first portion 32 ofskid 20.Second end conduit second portion 34 ofskid 20. Referring toFIG. 2 , during installation,skid 20 is positioned underlying one ofpanels 18 ofsupport structure 16 withfirst portion 32 ofskid 20 positioned within the enclosure defined bysupport structure 16 andsecond portion 34 ofskid 20 positioned outside enclosure defined bysupport structure 16. This enablesbladder 12 to be connected toconnection boxes connection manifolds support structure 16 to facilitate making fluid connections withbladder 12. - The manner of installation and operation of
liquid containment system 10 will now be described. Referring toFIG. 6 h,skid 20 is transported to a remote site withbladder 12 secured in position and folded. During transport, sidewalls 22 ofskid 20 are up as shown inFIG. 5 . Referring toFIG. 6 g, sidewalls 22 are lowered to provide access tobladder 12 for the purpose of unfolding it, as shown inFIG. 3 .First extension line 44 is connected tofirst connection box 38 andsecond extension line 46 is connected tosecond connection box 40. Referring toFIG. 6 f, the unfolding ofbladder 12 then commences as shown sequentially inFIGS. 6 e, 6 d, 6 c, 6 b, and lastly, 6 a. Referring toFIG. 2 ,panels 18 are assembled aroundbladder 12, withskid 20 positioned underlying one ofpanels 18 ofsupport structure 16 withfirst portion 32 ofskid 20 to whichbladder 12 is attached positioned within the enclosure defined bysupport structure 16 andsecond portion 34 ofskid 20 positioned outside enclosure defined bysupport structure 16. Connections are then made toconnection manifolds FIG. 1 ,bladder 12 is then expanded using air, liquid or a combination of air and liquid. When filled with liquid, bladder is supported bysupport structure 16. When the need forliquid containment system 10 has passed, a fluid is removed frombladder 12.Panels 18 ofsupport structure 16 are disassembled.Bladder 12 is then folded back ontoskid 20 as shown in the sequential folding illustrated inFIG. 6 a, 6 b, 6 c, 6 d, 6 e, 6 f, 6 g, and lastly, 6 h. - The manner of installation and operation of
liquid containment system 10 will now be described. Although the preferred shape for the support structure is circular, it will be appreciated that the support structure need not be circular and could be made multi-sided, most likely square or rectangular. The critical factor is that the support structure performs its intended purpose of supporting the bladder. Although a single bladder is illustrated within the enclosure, it will be appreciated that there could be two or more bladders that press against each other and receive support from a common support structure. Although it is envisage that the support structure is a plurality of panels that can be disassembled for transport, support structure could be a fixed structure that is not intended to be moved. In a fixed installation, all or a portion of the support structure could be provided by earth. This could involve mounding up the earth, excavating into the earth or taking advantage of naturally occurring topographical features. Although four openings into the bladder have been illustrated and described, it will be appreciated that the number of openings selected will be to suit the intended application. The bladder can be made of any suitable material that can be expanded and is compatible with the liquid to be contained. - Referring to
FIGS. 7-10 ,containment system 100 is amulti-sided body 110 consisting of a plurality ofpanels 112.

Referring toFIG. 7 andFIG. 8 , whenpanels 112 are delivered on site,panels 112 are connected to formbody 110. There are a plurality of connectors known in the art for connectingpanels 112, so the panel connectors will not be described in detail. Referring toFIG. 9 , the panel connectors illustrated are simplytongues 114 protruding from one side ofpanel 112 andparallel plates 115 protruding from another side ofpanel 112. Each oftongues 114 are inserted between one of the pairs ofparallel plates 115 and a bolt dropped into aligned apertures to preventtongues 114 from being withdrawn. The panel connectors do not need to be capable of retaining liquid, asbladder 116 will retain liquid. However, this size of bladder will be unstable in the absence of support, sobody 110 plays a critical role. Referring toFIG. 10 , one ofpanels 112 used to formbody 110 isskid 118 to whichbladder 116 is secured.Bladder 116 is then unfolded in preparation for use. Once substantially unfolded, continued deployment can be assisted by gas (air or nitrogen) or by liquids. There can be asingle bladder 116 or two bladders confined bybody 110 and each other. It will be appreciated thatbladder 116 will have fittings of various kinds, such ashose connection fittings 120 to provide for hose connection and ventfittings 122 to provide for venting. Other fittings may be required, depending upon the installation. - In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded.
