Definitions

  • the present invention relates to a method of pressure regulation of a cryogenic fluid reservoir connected to an installation consuming this fluid, which reservoir contains, under a storage pressure greater than atmospheric pressure, a cryogenic fluid in the liquid phase at the bottom of the reservoir and in the gaseous phase at the top of the tank, this tank being adapted to supply the consumer facility liquid withdrawn from the bottom of the tank, and to be supplied from the outside with fluid. It also relates to such a tank.
  • a pressure control method of a tank is described in the document US 2,850,882 .
  • the invention is particularly applicable to tanks called "low storage pressure", that is to say, the maximum pressure reached at the top of the tank is generally less than about 4 bar, the pressure indicated here and the pressures indicated thereafter being in absolute bars.
  • Such reservoirs are commonly used to store a cryogenic fluid, that is to say a fluid that at atmospheric pressure is liquid at a temperature much lower than 0 ° C. They are connected to at least one consumer installation, such as a freezing tunnel of food products.
  • the storage pressure of the tank being greater than the atmospheric pressure, the opening of a valve placed on the connection line of the tank to the consuming installation causes the liquid to move from its point of drawing to its point of use, without forced drive means and despite the pressure drops.
  • the pressure of the gas at the top of the tank is conventionally regulated so that this pressure remains substantially equal to a predetermined value. fixed, generally of the order of 2 to 3 bars.
  • the pressure of the liquid at the bottom of the tank varies according to the height of the liquid inside the tank, so that as the liquid level drops, the pressure of the liquid withdrawn decreases and tends to get closer to the gas pressure at the top.
  • a liquid height of about 10 meters implies a differential of pressure of the order of 0.6 bar between the gas pressure at the top and the liquid pressure at the bottom of the tank, at the drawing.
  • the object of the present invention is to provide a control method which guarantees a drawing flow at the bottom of the substantially constant reservoir and which, more generally, improves the storage, supply and withdrawal performance of the cryogenic fluid reservoir.
  • the subject of the invention is a method for regulating the pressure of a cryogenic fluid reservoir as defined above, in which the pressure of the gas at the top of the tank is varied according to the operating state of the this tank.
  • operating state of the reservoir must be understood to mean the different phases that it traverses during its use: drawing of liquid causing a drop in level, re-supply of the reservoir causing a rise in level , or even stand-by phases of the consumer installation where the tank is at rest.
  • a nitrogen tank 1 containing liquid nitrogen at the bottom, also called “tank”, and nitrogen gas under a pressure of about 2 bars at the top, also called “head” .
  • the level of liquid inside the tank is marked by the reference N.
  • the bottom of the tank 1 is connected to a consumer installation 2, for example a freezing tunnel, via a connecting pipe 3 provided with a closing valve 4.
  • the connection point of the pipe 3 to the tank 1, which is noted P, is commonly called "point of draw”.
  • the tank 1 comprises means 5 for pressurizing the gas at the top of the tank.
  • These means 5 comprise a line 6 connecting the bottom of the tank to its top, and is provided, upstream to downstream, of a device 7 for measuring the pressure of the liquid nitrogen, for example a manometer, a closing valve 8 (preferably a solenoid valve) and a vaporizer 9.
  • the tank 1 also comprises means 10 for venting the gas at the top of the tank.
  • These means 10 comprise a line 11 for outward evacuation, provided upstream downstream of a manometer 12, a closure valve 13 and possibly an air exhaust member, not shown, commonly called "silent".
  • a unit 15, controlling the means 5 for pressurizing the top, as well as means 10 for venting the top, is connected, for example by electrical connections, on the one hand to the pressure measuring apparatus 7 and 12, and on the other hand to the valves 8 and 13.
  • the control unit 15 is in this way adapted, on the one hand, to know, continuously or at regular intervals, the liquid nitrogen pressure at bottom of the tank 1 and nitrogen gas at the top of the tank and, secondly, to compare the value of the bottom pressure to a predetermined value selected, modifiable by the user.
  • the unit 15 is also able to control the opening, total or partial, and the closing of the valves 8 and 13 so as to regulate the pressures of the bottom and the top of the tank 1, as will be explained in detail later .
  • Means 16 for supplying nitrogen are also provided, so as to regularly, possibly continuously, supply liquid nitrogen to the tank 1.
  • these means 16 comprise a feed pipe 17 through the bottom of the tank 1 allowing a filling said "source”, and possibly a feed pipe 18 by the top of the tank for filling said "rain”.
  • the tank 1 also comprises an overflow member 19 known per se, for limiting the height of the liquid inside the tank.
  • the level of the liquid N is represented at its maximum.
  • This figure illustrates the example of a tank of 50000 liters, giving rise to a height N of about 10 meters, which creates in such a case a pressure differential between the top and the bottom of the tank. about 0.6 bar.
  • control unit 15 substantially maintains the liquid pressure at the point of drawdown P during the entire nitrogen withdrawal period.
  • the flow rate of the connection line 3 to the consumer installation 2 thus remains substantially constant, limiting the operating disturbances of this installation 2.
  • the level of liquid inside the tank 1 increases, causing a corresponding increase in the gas pressure at the top of the tank.
  • the unit 15 detects, by means of the measurements of the manometer 7, a pressure increase, and then controls the opening of the venting valve 13, which which decreases the gas pressure at the top and, consequently, that of liquid at the bottom of the tank.
  • the unit 15 maintains the opening of the valve 13 as the liquid pressure at the bottom of the tank remains greater than the aforementioned predetermined value.
  • the regulation of the tank 1 is substantially similar when the supply of liquid nitrogen is made by the top.
  • Source filling is, however, preferred over filling with rain, the latter tending on the one hand to decrease more significantly the gas pressure, and on the other hand to heat the liquid.
  • control unit 15 is adapted to improve the storage capacities of the frigories of the stored liquid. To do this, when the container 1 is not biased in racking and will not be biased a priori for a period of several hours (for example at night), the unit 15 controls the total opening of the valve of setting. 13. The gas pressure at the top of the tank then changes from a storage value of about 2 bars to substantially atmospheric pressure (residual pressure of a few hundred grams). In this state, the tank 1 is no longer able to supply the installation 2, the displacement of the fluid inside the pipe 3 is no longer ensured. However, by lowering the nitrogen storage pressure in this way, the enthalpy of the latter tends to increase, which amounts to having a lower temperature fluid than when it was under pressure. The fluid thus stored during these periods of non-use of the tank 1 therefore has a lower temperature than usual, guaranteeing a better "cryogenic quality" (in terms of available frigories).
  • the unit 15 controls the pressurization of the top of the tank, via the means 5, until the liquid pressure at the bottom of the tank reaches the predetermined value mentioned above.
  • the regulation method according to the invention makes it possible thus improve storage, supply and withdrawal performance.
  • the measurement of the liquid pressure is not carried out, as above, substantially at the point of drawing of the liquid, but is carried out at the highest point of altitude. along the connection line 3 between the tank 1 and the consumer installation 2.
