Definitions

  • the invention relates to the design of liquefied gas tanks, in particular to those which transport ships have.
  • Such reservoirs are already known, for example from French Patent No. 1,298,204, which comprise a sealed triple wall first delimiting the enclosure containing the liquefied gas, but also two safety and thermal insulation enclosures, generally filled with thermally insulating material.
  • the invention consists essentially in replacing this liquid with a body normally in the gaseous state and capable of SUBLIMING under the effect of a lowering of the temperature, and thus of taking the solid state, without going through the state liquid.
  • This substitution makes it possible to obtain numerous new and unexpected results compared to those obtained by the prior art, as set out below.
  • the simplicity of the invention does not therefore make it obvious, and allows it to be patentable compared to known art.
  • This sealing fluid is largely in the gas phase and comprises at least one body which, under a determined pressure at least equal to the gas pressure of the liquefied gas contained in the main enclosure, has a point (temperature) of SUBLIMATION on the one hand, lower than the temperature prevailing in service in the secondary enclosure, on the other hand, greater than the temperature of the liquefied gas contained in the main enclosure, while the pressure prevailing in the secondary enclosure is, in addition, effectively maintained equal to said determined pressure, the secondary enclosure being, moreover, connected to a pressure regulator for selective supply of gas.
  • the primary and secondary chambers are pressurized by admission of pressurized gas.
  • Liquefied methane and gas supplies are provided by the means described below.
  • a conduit 10 plunges to the bottom of the main enclosure 9 and is connected to a distributor 11 with three positions, to which are moreover connected two other conduits 12 and 13, one, 12, possibly connected to a station for storing a methane deposit, before loading the tank, the other, 13, connected to a pump 14 for discharging the tank.
  • a conduit 15 connects the primary enclosure 7 to a distributor 16 with three positions, while a source of liquid nitrogen under gas pressure 17 is connected to said distributor 16 by a conduit 18, and, that a discharge conduit to atmosphere 19 is connected to this distributor.
  • a conduit 20 connects the secondary enclosure 8 to a distributor 21 with three positions, while a source of compressed carbon dioxide 22 is connected to the distributor 21 by a conduit 23, and, that a discharge conduit to the atmosphere 24 is connected to this distributor.
  • FIG. 4 An alternative embodiment is shown in Figure 4.
  • a conduit 33 connects the secondary enclosure 8 to a distributor 34 with three positions, a flowmeter 35 being disposed on this conduit.
  • a source of compressed nitrogen 36 is connected to the distributor 34 by a conduit 37, a conduit 38 for discharge to the atmosphere being connected to this distributor.
  • the distributor 34 is provided with a voluntary control 39 for adjusting its position, but also with a return spring 40 and an automatic adjustment cylinder 41, which is connected to the conduit 33. In the absence action on the voluntary control 39, the combined antagonistic effects of the spring 40 and the normal pressure exerted on the jack 41, the distributor 34 is maintained in its second position. If, on the other hand, an abnormal drop in pressure occurs in the secondary enclosure 8, the effect of the spring becomes preponderant and places the distributor 34 in its first position.
  • FIG. 2 The configuration of FIG. 2 is that in which the primary barrier 5 has suffered slight damage, such as a crack 44 which allows liquefied methane to seep into the primary enclosure 7.
  • the liquefied methane accumulates at the bottom of this enclosure primary 7, up to a level 45.
  • the temperature of the part of the secondary barrier wetted by methane lowers to approximately - 160 ° C., and, in contact with this part, a thick layer 42 of carbon dioxide comes solidify by sublimation and release its latent heat.
  • the tank damage can be more serious, so that one arrives at the configuration of FIG. 3.
  • the crevice 46 in the primary barrier 5 lets a significant quantity of liquefied methane flow into the secondary enclosure up to a level 47.
  • a greater quantity of carbon dioxide solidifies, in a very thick layer 43, in a similar manner to the previous layer 42, but by impregnating a large part of the thermally insulating material and releasing more heat.
  • the secondary barrier 6 has a temperature, after a certain time, and in certain external circumstances, below the sublimation point of carbon dioxide, without however going down to ⁇ 160 ° C., temperature liquefied methane. Then, under these circumstances and in these places, a thin layer 31 of carbon dioxide in the solid state is deposited, which, moreover, is perfect for thermal insulation.
  • the distributor 21 and the source 22 allow the supply of the secondary enclosure 8 with carbon dioxide in the gaseous state.
  • the layer 42, 43 blocks any cracks in the secondary barrier 6 and heat has been produced during the condensation of carbon dioxide.
  • the double shell 4 has been protected from very low temperatures which would have made the steel constituting it fragile.
  • a first detection means is constituted by the pressure gauge 25. At the moment when the solid layer 42, 43 is formed, a relative vacuum tends to settle at the interior of the secondary enclosure 8, a vacuum precisely detected by monitoring the indications of the pressure gauge 25.
  • This new pressurization can, moreover, be carried out automatically by the distributor 34.
  • the jack 41 no longer maintains this distributor in its second position, the spring 40 placing then the distributor in its first position.
  • the gussets and fixing elements of the primary barrier 5 and secondary barrier 6 constitute, on the one hand, the weak zones of said barriers, on the other hand, thermal bridges. Because of this last characteristic, a deposit of solid carbon dioxide frost is deposited on these elements from the time of normal tank service. This frost therefore already provides, on the one hand, additional thermal insulation at the gussets and the like, on the other hand, additional sealing around these fastening elements, and therefore, in the weakest areas. primary and secondary barriers, this from the time of normal service. In the event of damage, the remedial remedy is already in place, at least partially.
