Definitions

  • the present invention relates to a filling station for liquid carbon dioxide to a mobile tank.
  • the invention finds a particularly advantageous application in the field of supplying liquid carbon dioxide (CO 2 ) for mobile tanks supplying the refrigeration units installed on isothermal trucks and requiring a rapid descent in temperature so as not to interrupt the chain of cold.
  • CO 2 liquid carbon dioxide
  • this prior pressure relief causes vaporization of the liquid carbon dioxide.
  • the filling time of the mobile tank is, in general, directly dependent on the pressure difference between the pressure in the mobile tank and the supply pressure of LCO2 in the storage tank.
  • the prior pressure relief therefore has the effect of slowing the transfer time from LCO2 to the mobile tank.
  • the smaller the pressure difference the longer the filling time.
  • the filling time is a key factor for the transport customer.
  • the driver of the vehicle transporting the mobile tank must connect two hoses to connect the LCO2 power transfer line and the gas vent, and open two manual valves located on the mobile tank before filling, this which is time and reliability constraining.
  • the equipment which has just been described with reference to the state of the art does not allow rapid transfer of the LCO 2 or an estimation of the degassing losses.
  • a constant concern of customers is to reduce the total filling time of the mobile tank to gain productivity and to know precisely the actual consumption of LC0 2 as well as the vaporization losses during filling.
  • this known equipment mainly consists of pressure reducers, which do not provide a high reliability of the overall installation, nor the possibility of managing the alarms and faults that may occur.
  • a first technical problem to be solved by the object of the present invention is to provide a filling station for liquid carbon dioxide to a mobile tank, comprising a storage tank for liquid carbon dioxide and a transfer line capable of bringing said liquid carbon dioxide from the storage tank to the mobile tank, which would make it possible to obtain a rapid transfer of LCO 2 from the storage tank to the mobile tank, and this in an automated, reliable and simple manner for the user who 'is the transporter whose transfer of LCO 2 is not the main job.
  • the solution to the first technical problem posed consists, according to the present invention, in that said filling station comprises a circulation line of carbon dioxide gas capable of maintaining downstream of the mobile tank a set pressure higher than the solidification temperature of the carbon dioxide.
  • the filling station object of the invention, makes it possible to obtain a high pressure difference between the liquid carbon dioxide storage tank and the gaseous vent of the mobile tank, hence a rapid transfer speed of the quantity of CO 2 required.
  • said gaseous carbon dioxide circulation line comprises a gas discharge valve controlled to open when the pressure downstream of the mobile tank is greater than said set value.
  • the invention preferably provides that said gas discharge valve is controlled by a pressure transmitter sensor.
  • a second technical problem which the present invention proposes to solve is to measure the quantity of carbon dioxide vaporized, lost during filling, so that it can be counted and deducted from the quantity of liquid CO 2 transferred, thus offering the customer better precision in knowing the actual volume transferred.
  • the invention recommends that the said gaseous carbon dioxide circulation line also comprises a buffer capacity connected to the said evacuation valve and capable of storing the carbon dioxide evacuated from the mobile tank during filling.
  • said buffer capacity comprises means for measuring the volume of carbon dioxide evacuated from the mobile tank during filling.
  • the measurement of the volume of carbon dioxide evacuated from the mobile tank during filling is carried out on the basis of the pressure difference in the buffer capacity between the start and the end of filling.
  • the buffer capacity therefore performs the functions of temporarily storing the quantity of the gaseous CO 2 vent, of measuring it, then of discharging it into the atmosphere in a delayed manner.
  • FIG. 1 is shown schematically a filling station of liquid carbon dioxide to a mobile tank 20.
  • This station comprises a tank 10 for storing liquid CO 2 , the storage pressure of which can vary between 14 and 20 bars.
  • a transfer line 100 is provided for bringing the liquid CO 2 from the storage tank 10 to the mobile tank 20 under a pressure of the same order of magnitude as the storage pressure increased by the hydrostatic height of the LCO 2 storage which allows the sub- cooling of the transferred LCO 2 and limits the inputs heat in the transfer line 100 and the flexible hoses 110, 210 for respective connection to the mobile tank 20 of the transfer line 100 and the line 200 for circulation of gaseous CO 2 .
  • the operation of the filling station in FIG. 1 is as follows.
  • the driver of the vehicle transporting the mobile tank 20 identifies himself at a recognition terminal 2, for example by introducing a magnetic card and validating a personal code.
  • the recognition terminal 2 also includes a modem for a telephone line ensuring the remote transmission of information to the customer.
  • the driver then connects the two hoses 110 and 210 to the mobile tank 20 and opens the two manual valves 120, 220 placed on this tank.
  • Terminal 2 for recognition gives authorization for filling with liquid CO2.
  • the filling valve 130 for supplying LCO 2 is authorized to open.
  • a second step of pressurizing the hose 210 and the mobile tank 20 The pressure in the mobile tank 20 is not directly measured, but the pressure transmitter sensor 230 measures the pressure downstream of the mobile tank 20 and the flexible 240.
  • this pressure is less than the CO 2 solidification pressure, this means that the mobile tank 20 is empty.
  • the mobile tank pressurization valve 240 opens 20 until the pressure measured by the pressure transmitter 230 exceeds the solidification pressure of the CO 2, i.e. 5.18 bars, until reaching a set pressure. which can typically be 8 bars. Filling with liquid is not authorized as long as the risk of carbon dioxide snow formation exists, a phenomenon always present with a pressure lower than the solidification pressure of CO 2 . Then, if the pressures measured by the pressure transmitter 230 and another transmitter 140 disposed on the transfer line 100 are both greater than the CO 2 solidification pressure, the passage to the filling step is authorized. Otherwise, the automat of distributor 1 generates a fault signal after a time delay and the driver is notified of the incident.

If the pressure does not reach the desired value, the PLC of dispenser 1 generates a fault after a delay, and the next step cannot start. This step is generally not carried out until the first start of the installation when the buffer capacity 30 is empty. Thereafter, the pressure transmitter 31 verifies that the pressure reaches the chosen nominal set value.

The discharge valve 270 is controlled to open as soon as the pressure downstream of the mobile tank 20 measured by the pressure transmitter 230 is greater than the set pressure in the buffer capacity 30 measured by the pressure transmitter 31. Buffer capacity 30 recovers the gas phase generated by the transfer of LCO 2 during filling of the mobile tank.
