Definitions

  • the invention relates to an artificial, underground cavern for storing gaseous natural gas according to the preamble of claim 1 and a method for its production.
  • natural caverns It is known to store natural gas under high pressure and low temperature in natural caverns.
  • these natural caverns consist, for example, of salt caverns, exhausted gas fields, so-called aquifer caverns or porous rocks at greater depths in the order of several hundred or even several thousand meters.
  • the invention is based on the formation of an artificial, underground cavern for the storage of natural gas under high pressure, in the order of 100 to 200 bar at a low temperature in the order of approximately -50 to -70 ° C, which gas-tight against surrounding rock and which can be created in an economical manner.
  • Fig. 1 shows a schematic representation of an embodiment of an underground, horizontally arranged cavern, while the
  • 1a to 1f show the various stages in the production of the gas-tight cover layer of the cavern, including the cavern in the state of natural gas storage.
  • FIG. 2 shows a schematic representation of an embodiment of a subterranean, horizontally arranged cavern modified compared to FIG. 1, while the
  • 2a to 2g show the various stages in the production of the gas-tight cover layer of the cavern, including the cavern in the state of natural gas storage.
  • the cavern 1 shown in Fig. 1 is tunnel-shaped and, for example, at a depth of 150 to 200 m in the surrounding rock, e.g. Granite blasted out. Although this horizontal arrangement of the cavern is particularly advantageous, the invention also encompasses e.g. vertically formed caverns.
  • the cavern is not arranged at a depth that ensures that the storage pressure withstands the hydrostatic head of the water contained in the surrounding rock.
  • a cladding 2 is introduced at a short distance from the cavern wall of, for example, approximately 2 to 10 cm, and ends at a short distance from the cavern base area of, for example, 10 centimeters.
  • This formwork 2 can be made of steel, aluminum or plastic, for example. Its wall thickness is determined in accordance with the hydrostatic water pressure in method step 2 described later (see FIG. 1b).
  • the formwork itself which in most cases is composed of several pieces, in particular is welded together, cannot be produced for the prints mentioned.
  • this formwork does not have to be gas-tight, but instead can have cracks and smaller holes, for example, which, as described below, are closed with the measures according to the invention, so that when natural gas is stored, the required gas tightness is secured against the surrounding rock.
  • the cavern 1 is closed off from the outside atmosphere by means of a pin 4 inserted into a bore 3, which e.g. can consist of metal or possibly also of plastic. Depending on the design of the cavern, in principle several pins can also be arranged.
  • the pin 4 is penetrated by three lines 5, 6 and 7.
  • the line 5 which is firmly fixed in the journal, ends in the gap space 8 formed by the cavern 1 and casing 2. It serves to supply water or to vent the gap space 8.
  • the line 7 is movable, ie slidably mounted in the pin 4 and penetrates the formwork 2.
  • This line serves either water or gas or remove liquid refrigerant from cavern 1 or introduce water or liquid refrigerant into it.
  • the line 7 is pushed into the lower region of the storage space 9 in a first process step (see FIG. 1a) and water is introduced through it until the storage space 9 and the surrounding gap space 8 are completely filled with water.
  • the pressure in the cavern corresponds to the sum of the atmospheric pressure and the hydrostatic height of the water in the cavern.
  • the temperature in the cavern space is approximately 4 ° C.
  • the cavern In the second process step (see FIG. 1b), water is pressed out of cavern 1 with the aid of natural gas, the cavern being under a pressure of approximately 20 bar.
  • the natural gas is introduced through line 6 and extracts water from the cavern through line 7, the end of which is in its lowest position.
  • Line 5 is closed, so that the gap space 8 remains filled with water.
  • the interior of the cavern is at approximately ambient temperature. It depends on the temperature of the natural gas injected.
  • the Formwork 2 At the end of this step, the Formwork 2 withstand the hydrostatic pressure of the water accumulated in the gap space 8.
  • the line 7 is moved upwards so far that its end lies above the water level of the water w located above the base area of the cavern, but still occupies a position in the lower region of the storage space 9.
  • liquid refrigerant k e.g. Propane
  • liquid refrigerant k e.g. Propane
  • Other hydrocarbons such as e.g. Ethane or ethylene
  • refrigerants such as Ammonia, freons and the like are not suitable for environmental or cost reasons.
  • the liquid refrigerant is introduced at ambient temperature, and since a pressure of approximately 20 bar is maintained in the cavern, the refrigerant will not start to boil.
  • the fourth method step can now begin (see FIG. 1d).
  • Natural gas is drawn off from the storage space 9 through line 6, and the refrigerant k in the lower storage space 9 begins to boil, as a result of which the temperature in all parts flooded by the refrigerant drops below 0 ° C., so that the water level is above the base area of the Cavern 1 and the corresponding water w located in the lower part of the gap space 9 freezes to ice e.
  • the storage space 9 is flooded with liquid refrigerant k.
  • the liquid refrigerant k which is continuously introduced through line 7, should boil immediately when it exits into the storage space 9, in order to avoid reheating at any point within the cavern 1.
  • the line 7 is continuously shifted upwards during the flooding in such a way that the outlet of the line 7 is always above the level of the boiling refrigerant k.
  • Refrigerant vapor and some natural gas generated during the boiling process flow out through line 6.
  • the level of the refrigerant rises continuously until the storage space 9 is completely filled with boiling refrigerant.
  • it must be taken into account that the boiling temperature of the refrigerant k rises in the bottom space of the storage space 9, even if the pressure on the surface of the boiling refrigerant is kept constant. The reason for this there is the level of the hydrostatic pressure of the liquid refrigerant in the floor space.
  • the ice will still not melt unless the heat from the rock surrounding the cavern is so great that the ice begins to melt.
  • an advantageous measure consists in reducing the pressure at the level of the boiling refrigerant while the refrigerant is rising and also not dimensioning the cavern depth too great.
  • the refrigerant k is removed from the storage space 9 of the cavern 1, namely by the fact that the refrigerant is pressed through line 7 with cold natural gas, for which purpose the cold natural gas of, for example, approx. -20 to - 70 ° C is introduced through line 6.
  • the pressure at the refrigerant level k is kept low, e.g. to 1 to 2 bar in order to ensure that some refrigerant k constantly boils.
  • the formation of the ice jacket in the gap space 8 also, for example, instead of the procedure described above can only be done with cold gas. In this case, however, very large amounts of gas have to be circulated and recooled because of the relatively poor heat transfer between gas and water.
  • a seventh process step the process of storing natural gas at a pressure of approximately 60 to 150 bar and a temperature of approximately -70 ° C is explained (see FIG. 1g).
  • This natural gas can originate, for example, from a pipeline or from a plant as described in Swiss Patent Application No. 827 / 88-3.
  • the cavern is ready for storage (cf. FIG. 1g).
  • Cold natural gas is initially introduced through the line 7 pushed into the lower part of the storage space 9, for example with pipeline pressure at approximately 60 bar and approximately -70 ° C. Lines 5 and 6 are closed.
  • the methane in the natural gas is hydrated at the "open" locations of the formwork 2, ie in its cracks and small openings upon contact with the ice from the gap space 8.
  • This methane hydrate thus formed has elastic properties and seals the previously open positions gas-tight to the outside.
  • the ice in the gap space 8 is brittle at the pressure and temperature conditions mentioned.
  • the natural gas to be stored is compressed to the desired storage pressure of, for example, 150 bar and introduced into the storage space 9 through line 7. If necessary, stored natural gas is withdrawn from cavern 1 through line 6.
  • cold natural gas is taken from a refrigeration system, not shown, installed above ground and introduced through line 7 into the storage space 9, and a corresponding amount of natural gas heated therein is taken through line 6 and recirculated into the refrigeration system.
  • This measure is advantageous because it ensures that the cavern always stays cold and prevents ice from melting at any point in the "ice jacket" surrounding the storage space 9.
  • FIG. 2 shows a variant embodiment of a cavern designed according to the invention compared to the exemplary embodiment described above (see FIG. 1).
  • This embodiment offers certain advantages over the first embodiment, which mainly consist in the fact that considerably less refrigerant is required to produce a gas-tight cover for the storage space of the cavern with respect to the surrounding rock.
  • a second formwork 10 is arranged within this at a distance of a few centimeters, the ends of which are set back by a distance from the first formwork 2'.
  • This formwork corresponds in its training in terms of material and method of manufacture with the formwork 2 '.
  • two lines 11 and 12 are passed through the pin 4 ', which open into the gap space 13 formed by the two casings 2' and 10. These two lines, which are fixed in the pin 4 ', serve to fill the gap 13 with gas or liquid or to remove gas from it.
  • the cavern 1 ' is vented analogously to the first exemplary embodiment (see FIG. 1a) and filled with water for this purpose. All four lines 5 ', 6', 11 and 12 are used to displace the cavern air.
  • liquid refrigerant k is introduced into the gap space 13, namely until the water level above the base of the cavern 1 'and the lowermost part of the casing 10 are completely flooded with refrigerant.
  • the lines 5 ', 7' and 11 are closed and the lines 6 'and 12 are open to lower the pressure in the cavern 1', so that the refrigerant k boils.
  • the pressure between the gap space 13 and the storage space 9 ' is controlled in such a way that a higher level of the liquid refrigerant k in the gap space 13 than in the storage space 9' is maintained. In this case, however, the lower part of the casing 10 remains flooded with refrigerant k.
  • the water located in the bottom of the cavern 1 freezes the water in the lower part of the outer gap space 8 'to ice e.
  • liquid refrigerant k is introduced into the lower gap space 13 through line 12 at room temperature. Gas and refrigerant vapor escape through line 12 from the gap space 13 and through line 6 'from the storage space 9'.
  • the amounts of gas or vapor discharged are controlled such that the liquid level in the storage space 9 'is lower than in the gap space 13, the level of the boiling refrigerant k in the gap space 13 constantly increasing until this gap space is completely filled with boiling refrigerant. When this is reached, the water w in the outer gap space 8 'is completely frozen to ice e.
  • the pressure on the uppermost surface of the refrigerant in the gap 13 is greater than in the interior 9 ', so that the refrigerant boils in the gap 13, but not in the interior 9'.
  • FIGS. 2e and 1e shows the savings in refrigerant when using a double casing 2 ', 10 compared to a single casing 2, since with simple casing the interior 9 of the cavern 1 must be completely filled with refrigerant.
  • the liquid refrigerant from the gap space 13 and from the storage space 9 'with the help of cold natural gas at about -70 ° C through the lines 12 and 6' is pressed.
  • the Movable line 7 ' is lowered and used to suck off the refrigerant located in the bottom of the cavern 1'.
  • This method step essentially corresponds to the corresponding one of the first exemplary embodiment.
  • methane hydrate which closes the open areas in a gas-tight manner with respect to the surrounding rock.
  • FIGS. 1g and 2g further shows that more effective cooling can be achieved in a cavern with a double formwork than in a cavern with a simple formwork, since the gas velocities on the surface of the formwork 1 'are higher and therefore a better one Heat transfer is achieved.
  • the formwork can be produced in an extremely cost-effective manner, since it does not have to be made absolutely gas-tight. Even if during the time in which the reservoir is filled, due to pressure fluctuations, e.g. may be caused by earth movements or due to thermal expansion of the ice layer, e.g. As a result of heat from the surrounding rock, cracks in the casing or in the ice layer should develop, methane hydrate immediately forms again in the "open areas" due to the low storage temperature and the high storage pressure, so that gas tightness to the surrounding area also occurs during storage Rock is guaranteed.
  • the formwork In order to absorb the expansion of the water during ice formation in the gap space, it is advisable to produce the formwork from a material with elastic properties, or to bring about a sufficient elasticity of the formwork by appropriate shaping of the wall.
  • the wall can be made from corrugated sheets.
