Definitions

  • the subject of the present invention is a storage installation of a liquefied gas under pressure in a pressure enclosure and a process for storing a liquefied gas under pressure in such a pregnant.
  • FIG. 1 there is shown such an installation of known type which is constituted by the cryogenic resistance enclosure at the pressure 12 in which the liquefied gas 14 is stored.
  • the installation also includes a withdrawal tube 16 at the bottom of the tank and a safety valve 18 connected to the upper part of enclosure 12.
  • the installation is also equipped with a system 20 for detecting the level of liquid 22 in the tank.
  • This system 20 provides the percentage of the height of the enclosure occupied by the liquid and it is based on a differential measurement of pressure. This measurement controls the filling of the enclosure as soon as this percentage drops below 30%.
  • a first object of the invention is to provide an installation for storage of a liquefied gas under pressure which makes it possible to lower the cost especially with regard to the amount of metal used for the realization of the pressure enclosure while of course maintaining security conditions strictly equivalent to those provided by standards.
  • the invention is based on the one hand on the fact that the inventors have demonstrated that as long as the amount of liquid of liquefied gas contained in the tank is at least equal to 10%, the temperature of the enclosure wall remains much lower than the temperature ambient generally taken as a calculation parameter and that, more precisely, this temperature remains below at least - 50 ° C and more precisely at -80 ° C.
  • the determination calculations, especially the thickness of the wall of the pressure vessel are made from this temperature, which leads to thicknesses very significantly reduced and therefore a decrease in the quantity of steel use.
  • the installation is planned in such a way that if the actual temperature of the enclosure wall exceeds the temperature taken into account in the calculations, the valve is automatically controlled to drop the pressure inside the enclosure at a pressure substantially lower than that which was taken in account for the calculation of the wall thickness, whereby this increase in temperature is offset by decrease in pressure as to the stresses to which the wall of the enclosure is subject.
  • the quantity G is the temperature itself inside the pressure vessel.
  • the quantity used is the percentage of the height of liquid contained in the pressure resistance enclosure, height which is directly like have established the inventors in relation to the external temperature of the wall of the enclosure.
  • This variant of implementation has the advantage to use a liquid level detector in the resistance chamber the pressure that already exists in most installations.
  • Another object of the invention is to provide a method of storage of liquefied gas under pressure in an enclosure.
  • the liquid filling rate is between 30 and 100% since, in normal operation, the enclosure is filled as soon as the liquid filling rate is less than 30%. With this rate of filling, the enclosure wall remains at a temperature which does not never rises above -130 ° C. The inventors also observed that even if the filling rate becomes 10%, the temperature of the enclosure wall never rises above -80 ° C.
  • the invention proposes to calculate the dimensioning of the wall of the pressurized storage enclosure for a temperature of - 80 ° C or at least for a temperature much lower than ambient temperature, for example - 50 ° C, and for standard operating pressure P s .
  • the calculations carried out under these temperature and pressure conditions make it possible to reduce the thickness of the wall of the enclosure by 30 to 40% less than that obtained conventionally by using ambient temperature to carry out these calculations.
  • the installation is equipped with detection means directly representing the temperature of the wall or preferably a quantity correlated to this temperature and a pressure limiter at a pressure P 1 lower than the operating pressure to cause the pressure inside the enclosure to drop if the design temperature is exceeded.
  • This installation comprises the tank 30, the thickness of the wall 32 of which has been calculated according to the standard in force for a service pressure P s and for a service temperature T s equal to - 80 ° C.
  • the installation also includes the control system 20 for the liquid level 22 inside this tank.
  • the pipe 34 which puts the safety valve 18 in communication with the interior of the enclosure 30 is also connected by the pipe 36 to a controlled valve 38.
  • This controlled valve is interposed between the pipe 36 and a pressure limiter 40 whose the setting pressure is equal to P 1 , P 1 being substantially lower than the operating pressure P s for which the enclosure has been calculated.
  • the liquid height percentage information G produced by the measuring device 20 is compared with a reference percentage G 'in the comparator circuit 42.
  • G' is chosen equal to 12% and preferably equal to 10%. If the result of the comparison R is that the percentage of liquid becomes less than 10%, the valve 38 is controlled to be opened so that the interior of the tank is connected to the pressure relief valve 40 set to the pressure P 1 . On the other hand, in normal operation, as long as the percentage of liquid height G remains greater than G ', the valve 38 remains closed.
  • FIG 3 there is shown a second embodiment of the installation in which there is the tank 30 with its wall 32 whose thickness has been calculated as previously indicated as well as the safety valve 18 connected to the enclosure by the pipe 34 and the level measurement device 20.
  • at least one temperature sensor 42 is placed on the external face of the wall 32 of the enclosure, placed near the upper end of the enclosure 30 and preferably a plurality of sensors 42 disposed at this same level which therefore deliver a signal representative of the external temperature of the enclosure T e .
  • This temperature is compared in the comparator 44 with a signal representative of the temperature T s at which the calculation was carried out, that is to say corresponding to a value of - 80 ° C.
  • the result of this comparison is used to control a valve 46 which is interposed on the line 48 between the interior of the enclosure 30 and a pressure limiter 50 set to the value P 1 lower than the operating pressure P s . If the measured temperature T e becomes higher than the reference temperature T s , the valve 46 is open and the interior of the enclosure 30 is connected to the pressure limiter 50.
