Description

Storage installation for liquified gases
The present invention relates to the stowage arrangement of liquid gas.The liquid gas here is meant such as boiling point under a barometric pressure such as LNG Liquefied natural gas and is lower than zero degree, through continuing the gas that cooling can be liquefied.
Such gas can be housed in the rock cave that is called as the storehouse, ground of cutting.Another program is to be housed in the gas holder.This gas holder can be laid in below ground or above also can the above part below ground in part ground.If the device place wholly or in part below ground, the liquid gas of storage can reach in more than the phreatic surface or below.The barometric pressure on liquid gas surface is about a bars absolute, and is slightly high usually, as 1.1 bars absolute.In liquid gas inside, the pressure nature increases along with the intensification of the degree of depth, but still can be lower than presumable phreatic air pressure on every side.The low temperature of gas can keep by conventional art, just, with the liquid state of congealing into again of (gaseous state) gas input refrigerator more than the liquid level, presents back in the gas holder again.
People have attempted storage liquid gasification in concrete-lined rock cave is arranged.Gas can be isolated by thermal-protective material appended in the concrete liner, or in some cases, can directly enclose thermal-protective material on rock and isolates without the steel wall.Evidence owing to the shrink grading difference of different material in cooling procedure, can produce and adhere to problem incessantly, and the danger that causes thermal-protective material to come off is arranged.If liquid gas need not be by the membrane sealed of speciality steel in addition, this storage facilities will be easy to leak, and produce extra-pay then.
More than ground or following gas holder can be steel structure or cast and lining cutting steel layer by concrete.Because common iron can become fragile at low temperatures, can only use very expensive special rolling-mill section.This cost is a serious unfavorable factor making this device.
Storage installation for liquified gases based on the present invention has not only solved the problems referred to above, and at the storage device of the cost that is lower than storage solution gasification under subzero 45 situations about spending well below aforesaid various (in the steel gas holder).
Device according to this invention is such: gas holder is surrounded by rock or concrete layer, and itself is cast by concrete, can be heat insulation.Its feature is that gas holder is all or part of and is surrounded by packing material.Packing material is heat insulation, and has seal, in the space between gas holder and rock or concrete casing.
The sealing effect realizes by packing material.This can only pass through above-mentioned packing material, or at the internal layer of stuffing, skin and/or centre add that one or several only oozes film.
This invention equipment that makes can place the rock cave of digging cutter, or in loose soil, can part during loosening the soil partly on the face of land, or fully on the face of land.Here " loosening the soil " is meant any non-physical material, as soil, sandy soil, sandstone beach, grit layer or their mixture.Loosen the soil can place equipment around, or in loosening the soil, make the groove place apparatus.When shell was sealed gas holder, this shell can absorb the pressure in the stuffing, and the medium around equipment will not rely on so for example loosens the soil, or the part atmosphere that partly loosens the soil, or all was atmosphere.
When packing material has seal, can use clay, and can add thermal-protective material.Typical additive is loose Leca.Add that this material can be avoided in gas holder or outside add special thermal-protective coating more in addition, or significantly reduce the thickness of thermal-protective coating.When temperature when zero degree drops to a certain degree, clay can expand, thereby sticks to firmly all the time between rock or shell and the concrete gas holder.But make gas holder negative excessively for fear of the expansion because of clay, and/or make the shell pressurized, the shim that can add a kind of " material of can crushing " is between clay and gas holder, or between clay and shell.This " material of can crushing " can be cracked under certain pressure, prevents that then high pressure from transferring on gas holder and/or the shell.If thermal-protective coating places between packing material and the concrete, this insulator just can serve as " material of can crushing ".
Packing material can be natural also processing.Because stuffing itself should play airtight effect, its permeability should be minimum, and stuffing plays the effect of locking device as barrier film like this.Typical natural material is exactly the clay that adds a large amount of particles.Typical rapidoprint is Powdered or the clay of spherical shape (bentonite clay), and the lime powder that adds entry therein and fully grind, industrial slag, light ash (as volcanic ash), silica dust etc.Though this not necessarily, helps the thermal insulation of stuffing.Insulator can place the internal layer or the skin of gas holder, and is preferably dilatable in subzero, and this is not a necessary condition certainly.
After device started, (in fact, as long as the device operational temperature will descend) just can heat stuffing during temperature stabilization.If stuffing is a clay, or similarly can become fragile and be easy to cracked material at low temperatures, its temperature in whole or in part should be controlled at more than the uniform temperature, and just stuffing is transferred to more than the temperature of fragility by plasticity.Equally, if stuffing contains one or more layers film, should be controlled at temperature and be higher than more than the temperature that film can become fragile.This heating process makes that the alternative condition of thin-film material is not a harshness so.For example, the steel of common grade, just the special rolling-mill section of non-costliness is also applicable.
When stowage arrangement injection liquid gas operates, outer rock or the shell of gas holder, presumable insulator, stuffing and cold air can slowly cool off, zero warm face is passed to shell by repertory and is therefore considered time factor, and adding insulator is favourable to start-up course.When device was enabled, liquid gas can evaporate because of the heat leak of object (being the concrete gas holder, presumable insulator, stuffing on every side and rock skin) on every side.Remove steam, add condensing air, the evaporation of pressurized gas can make the temperature of ambient body continue to descend.Have only when the temperature of object drops to a certain degree around, evaporation just can reach minimum degree, and makes device be in steady-working state.The required time of this temperature-fall period can shorten greatly because of add insulator in stuffing.Shorten starting time and have very big economic value for the huge equipment of these investments.
Adding insulator can make stuffing and rock or shell not need to bear the low temperature that does not have under the insulator situation.The airtight problem of liquid gas also can be avoided like this.
In certain stability range, can not shrink or cracked between the stuffing of gas holder and rock or shell.Low excessively to make stuffing transfer fragility to by viscosity cracked then in order to prevent temperature, and film is become fragile, and can dispose heating element, as vacuum tube, water pipe, heating element, mixes temperature transducer again.So just can heat effectively, avoid stuffing and film cracked or become fragile because of low temperature.Heating almost reaches at device just to be carried out when stablize operating state, because if add affiliation prolongation starting time when starting.
This device has very high Security.Have outside gas holder under packing material and the presumable phreatic situation, because stuffing can be not cracked, film also has closing function, concrete gas holder and presumable insulator and (or) crack in the shell can't cause outwards gas leakage or inwardly leak.
With the steel gas holder, except cost saving, it can also guarantee that in concrete gas holder potential fracture can not cause the leakage of any liquid state or gaseous product, because stuffing on every side and presumable film and underground water have sealing process, has prevented further to external leakage.
The insulator of concrete gas holder can be external also can be built-in.Because can produce the crack in the concrete gas holder, therefore under any circumstance thermal-protective material must be can not be stored thing to permeate, and can not react with it.
Below will be described the device that designs according to this invention with legend.In appended figure, Fig. 1 to 5 has showed the gas holder that places the rock cave, and Fig. 6 to 9 has showed the gas holder that places concrete casing.
