Definitions

  • the present invention relates to a process for supplying carbon dioxide under high pressure by means of a high pressure pump, from a storage tank for liquid carbon dioxide at a temperature below room temperature, this method being of the type described in the preamble of claim 1. It applies for example to the supply of C02 under a pressure of the order of 80 to 130 bars.
  • a conventional technique for obtaining CO 2 under high pressure consists in pumping the liquid CO 2 in two stages: a supply pump draws off the liquid, generally stored at -20 ° C., 20 bar absolute, and brings it to an intermediate pressure which is the suction pressure of the high pressure pump.
  • the feed pump works in cold, in severe conditions, and becomes covered with ice, which makes it difficult to work on this pump.
  • the object of the invention is to provide a simple and reliable technique eliminating the drawback in question. To this end, it relates to a process of the aforementioned type, characterized by the content of the characterizing part of claim 1.
  • the invention also relates to an installation intended for the implementation of such a method.
  • This type of installation comprising a storage tank for liquid carbon dioxide at a temperature below ambient temperature; a high pressure pump; an intermediate container entirely situated below the minimum level of the liquid in the tank and connected to the lower and upper parts of this tank; means for maintaining this intermediate container at a given temperature; means for sub-cooling the liquid contained in said container; and a pipe for bringing the sub-cooled liquid to the suction of the pump, is characterized in that said holding means are intermittent heating means; and said given temperature is close to ambient temperature.
  • the installation shown in FIG. 1 is intended to supply, via a pipe 1, the use of liquid CO 2 under a regulated high pressure which is, for example, of the order of 80 to 130 bars, in the vicinity of ambient temperature.
  • It essentially comprises a tank 2 for storing liquid C02 at -20 ° C, 20 bars absolute, of large capacity, two intermediate containers 3 of very lower capacity, for example of the order of 100 liters, a bottle of liquid C02 4 , two centrifugal feed pumps 5, associated respectively with the receptacles 3, a high pressure pump 6, of the volumetric membrane type provided with a regulation device 7, an accumulator 8 and a device 9 for sub-cooling the high pressure liquid .
  • the containers 3 are arranged entirely at a level below the minimum level of the liquid in the tank 2, in practice entirely below the bottom of this tank.
  • the upper part of the tank is connected in parallel to the two containers 3 by lines 10, and the lower part of the tank is connected in parallel to these two containers by lines 11.
  • the bottle 4 is also connected in parallel to the two containers 3 by lines 12.
  • the suction of the pump 6 is connected in parallel to the two containers 3 by lines 13 each equipped with a feed pump 5.
  • a line 14 provided with a throttle (or, alternatively, a calibrated valve) 15 connects the discharge of each pump 5 to the associated container 3.
  • Each container 3 is provided internally with a heating resistor 16 adapted to maintain the content of the container at a constant temperature close to the ambient, for example + 20 ° C.
  • the accumulator 8 is divided into two chambers by a membrane; one of these chambers is connected to a bottle 17 containing an auxiliary gas, for example, nitrogen, under the desired high pressure (set pressure), and the other chamber is connected to the discharge of the pump 6.
  • the operating line 1 leaves from the entrance to this last room.
  • the regulating device 7 comprises a differential pressure sensor 18 which measures the set pressure and the discharge pressure of the pump 6. It sends to a frequency converter 19 a signal representative of the difference between these two pressures, and the frequency converter governed as a function of this signal the speed of the gear motor 20 for driving the pump 6 and / or the stroke of its piston, by increasing or decreasing it following that the delivery pressure is lower or higher than the set pressure.
  • the receptacles 3, the bottles 4 and 17, the pumps 5 and 6 and the accumulator 8 are arranged in a room 21, the temperature of which is maintained continuously at the aforementioned value of + 20 ° C.
  • the pipe 1 is cooled by a few degrees, for example to +10 to + 15 ° C, by the device 9.
  • This device includes a jacket 22 surrounding the pipe 1, a water conditioner 23 and a circulation circuit comprising a pump 24 and adapted to circulate the water against the current of CO 2 in the jacket 22.
  • the upper part of the reservoir 2 is connected to the suction and discharge of the pump 6 by lines 25, and the lines 1, 10 to 13 and 25 are provided with solenoid valves allowing the operation of the installation, which will now be described.
  • the resistors 16 are started up, bringing the liquid contained in the containers 3 to + 20 ° C., with a corresponding increase in pressure but without vapor pressure.
  • the solenoid valves of the conduits 12 are then opened, which puts the liquid contained in the two containers 3 in equilibrium with its vapor, at + 20 ° C., 58 bar absolute, and the pumps 5 are started up.
  • the solenoid valves pipes 13 are closed, a higher pressure is created therein, thanks to the presence of the throttles 15, for example of the order of 70 bars.
  • the liquid C0 2 is therefore sub-cooled, which ensures a single-phase supply of the high pressure pump 6.
  • the solenoid valve of one of the lines 13 is then opened, and the high pressure pump 6 is started up.
  • the latter delivers liquid C0 2 under high pressure in the accumulator 8 and in the line 1, which is purged of the CO 2 gas it contained, and the pressure increases in line 1 to the desired value.
  • This liquid, during its passage in the pipe 1, is sub-cooled by the device 9 on leaving the room 21, which ensures at the outset the recondensation of the gaseous C0 2 which may be in the pipe 1, then a single-phase liquid distribution .
  • the high pressure is maintained at a constant value by regulating the flow rate of the pump 6 by means of the device 7, as described above.
  • the pulsations of the pump 6 are not felt in the pipe 1.
  • FIG. 2 differs from that in FIG. 1 only in the way in which the liquid is sub-cooled on leaving the containers 3. In fact, in this case, instead of increasing its pressure at constant temperature , its temperature is reduced at constant pressure. For this, the pumps 5, the return pipes 14 and their throttles 15 are eliminated, and each pipe 13 passes through a heat exchanger 26 cooled against the current by the water supplied by the device 9 and connected in series with the jacket 22, upstream thereof.
  • liquid C0 2 contained in line 1 can optionally be vaporized to be used in the gaseous state.
