Definitions
- the invention relates to a pressurized gas storage installation with a tank which is arranged to store gases at an internal pressure of the tank, a membrane, pressure-tight, arranged on the inner wall of the tank, a structural wall arranged to the outside of the tank, a crack control device and a drainage installation integrated into the structural wall, in accordance with the preamble of claim 1.
- Such an installation is known from US 2001/0002969 A1.
- This installation comprises a pressurized gas storage tank, using a waterproof steel membrane for storing gas at an internal pressure of the tank, and a mechanically stable structural wall disposed outside the tank.
- a crack control device is present in the form of a mesh type network and a drainage installation, which are integrated into the structural wall.
- the mesh type network allows cracks to be managed over a large area so that large cracks are divided into a plurality of small cracks.
- the object of the present invention is to propose an installation according to the preamble of claim 1, in which, with a relatively thin structural wall, and in the presence of surrounding rocks that are not very resistant, the effect of a leak on the stability of the surrounding rocks is relatively weak.
- the crack control device comprises a number of crack control elements, which are constructed and arranged so that cracks formed in the structural wall extend in preferential directions from the membrane to the drainage installation, and in that the drainage installation is formed permeable to gases at least in permeability zones arranged in the preferred direction of the cracks.
- an underground reservoir of pressurized gas is generally sized taking into account the targeted or feasible storage pressure, the geomechanical properties of the rock mass considered, the depth of the reservoir, and finally the section of the reservoir.
- the section of the tank is decisive for the calculation of the minimum depth of storage.
- the storage depth must be as low as possible while respecting a high safety factor.
- the pressure In the case of a high-pressure gas leak, the pressure must not be propagated in the rock mass. This propagation would result in a drastic increase in the active section which would then exert much greater efforts on the rock mass towards the surface, which could cause a failure of this one.
- the choice of the depth of storage would then be distorted. It is therefore imperative to ensure that in the event of a leak, the leakage pressure drops drastically as soon as the pavement is crossed and does not propagate in the rock mass. Since, according to the invention, the gas leaks are deaerated under pressure, the risk of the pressure propagating in the rock mass is eliminated. So we can size the burial depth by taking into account the tank section and avoid the obligation to bury the tank much deeper. This avoids a significant additional cost of the installation. Indeed a deeper burial implies an additional cost of civil works to dig a reservoir deeper.
- the zones of permeability may consist of recesses, constituting a simple and effective solution
- At least a plurality of cracks control elements may be disposed adjacent to permeability zones of the drainage device, thereby improving the guidance of leaks to the drainage device,
- At least a plurality of crack control elements can be firmly attached to the drainage device by means of respectively at least one fixing, to ensure their position, especially at the time of installation of said reservoir ,
- the crack control elements may comprise a guide section extending at least in portions between the drainage device and the structural wall, constituting a simple and effective solution,
- the guide section of at least a plurality of crack control elements may be constituted by a flat plate, constituting a simple and effective solution, - said installation may comprise rupture initiation recesses made in the surrounding rock. , thus making it possible to promote the distribution of cracks, and to avoid the formation of a smaller number of larger openings potentially very damaging,
