Definitions

  • the present invention relates to a method for delivering cryogenic liquid as well as an installation for implementing this method.
  • the invention may relate to any type of cryogenic liquid, that is to say any liquid obtained by cooling to very low temperatures (generally below -100° C.) gases (pure or mixtures of gases) such as nitrogen, helium or natural gas (methane).
  • gases pure or mixtures of gases
  • nitrogen, helium or natural gas methane
  • cryogenic liquids For certain uses of cryogenic liquids, the liquid is stored in a tank of relatively large size and means are provided for delivering relatively small quantities of liquid into containers, such as for example a tank of a truck.
  • a refueling station with a storage tank and pressurized distribution means adapted to the container to be filled, generally comprising a pump making it possible to transfer cryogenic liquid from the storage tank to a tank of a vehicle.
  • the invention also relates to the transfer of cryogenic liquid to another type of container, for example a carboy of cryogenic liquid or a dewar.
  • the term “container” means any type of reservoir or receptacle or the like adapted to contain liquid, and more particularly here a cryogenic liquid.
  • liquid transfers from the tank to a carboy or a dewar, for example
  • refueling from the tank to a vehicle tank.
  • the document FR-2 997 165 relates to a process for filling a tank with a cryogenic liquid, from an upstream storage, where there is a filling station through which passes a first path connecting the storage to the tank and allowing the transfer of cryogenic liquid from the storage to the tank, and a second path connecting a gas outlet from the tank to the filling station and making it possible to bring the gases to be evacuated from the tank to the filling station, the second gas return line to the station being devoid discharger but being equipped with a solenoid valve or several solenoid valves arranged in parallel, normally closed, the filling being controlled by the action on the solenoid valve to open it as much as necessary so as to obtain a pressure difference Delta P (between storage and tank) desired, and a final pressure value in the tank conforms to a desired set point value, associated with the considered tank that must be filled.
  • a filling station through which passes a first path connecting the storage to the tank and allowing the transfer of cryogenic liquid from the storage to the tank, and
  • the document FR-3 006 742 discloses a device for filling a tank with a liquefied gaseous fuel at a cryogenic temperature, comprising a source tank for storing gaseous fuel in the liquid state at a cryogenic temperature, a withdrawal pipe comprising a pump, the draw-off line comprising an upstream end connected to the source reservoir and a downstream end comprising a connector intended to be connected to a reservoir to be filled, the draw-off line comprising, downstream of the pump, a bypass portion transiting inside the source tank and comprising a submerged heat exchanger, the draw-off line comprising a system of bypass valve(s) shaped to control the relative proportions of the pumped fluid transiting and not transiting in the bypass portion, to regulate the temperature of the liquid withdrawn during filling and the filling device comprises a cryocooler connected to the tank s source to selectively liquefy gas present in the source reservoir.
  • cryogenic liquid delivery station such as LNG (Liquefied Natural Gas)
  • LNG Liquefied Natural Gas
  • its tank is sometimes under pressure. due to the evaporation of the cryogenic liquid in the tank.
  • a degassing that is to say to withdraw gas from the tank to lower the pressure in the latter.
  • cryogenic liquid is brought under pressure to the tank.
  • the dispensing of liquid stops when one of the two following conditions is met: the pressure in the reservoir exceeds a predetermined threshold or the flow rate of liquid falls below a predetermined threshold.
  • the object of the present invention is therefore to allow a good filling of a tank, that is to say to automatically fill the tank to its nominal filling level, which may correspond for example to the maximum authorized filling level.
  • Another object of the present invention is to make it possible to determine fairly precisely both the quantity of liquid introduced into the tank and the quantity of gas which is withdrawn therefrom.
  • the implementation of the present invention will preferably have zero additional cost compared to a station for delivering cryogenic liquid (in particular LNG).
  • a degassing operation can be stopped, for example, when the pressure in the reservoir drops below a predetermined threshold and/or if a quantity of gas, predetermined as a function in particular of a quantity of liquid delivered and/or or a quantity of gas withdrawn in previous steps, is withdrawn from the tank.
  • the delivery process can also, for example, be stopped if the quantity of gas withdrawn during the last degassing operation carried out is below a predetermined threshold and if the quantity of cryogenic liquid delivered during the last liquid delivery operation cryogenic is above a predetermined threshold, after a final delivery of cryogenic liquid has then been performed.
  • the present invention also relates to a cryogenic liquid delivery installation comprising a cryogenic liquid supply pipe and optionally a degassing pipe, characterized in that it further comprises a management system for the implementation of each of the steps of a process as described above.
  • Tank 2 (cf. figure 2 ) can be a tank of a vehicle or an independent container (bottle, dewar, ).
  • the cryogenic liquid is for example LNG (Liquefied Natural Gas) but it can be any other type of cryogenic liquid (liquid nitrogen, etc.).
  • LNG Liquefied Natural Gas
  • the first step R thus consists here in connecting the tank 2 to an LNG delivery station.
  • the latter allows the transfer of a limited quantity of LNG from a storage tank (not shown) to tanks, or the like, of smaller sizes.
  • the connection between the tank 2 and the delivery station is made by a flexible pipe which comprises two pipes: a first pipe, called the supply pipe 4, which is intended to bring the LNG from the storage tank to the tank 2 of the truck and a second pipe, called degassing pipe 6 intended to evacuate the elements under gaseous phase present in tank 2.
  • the user who wishes to obtain the filling of his reservoir then requests this filling by pressing, for example, a button (not shown).
  • step: P? This pressure must be greater than the saturation pressure of the liquid (LNG) to avoid immediate evaporation of the liquid introduced into tank 2. This condition is most often met because there is generally still liquid in tank 2. It is appropriate however, to also ensure that this pressure is not too high. Indeed, if the pressure is too close to the maximum allowable pressure of the tank or even if this pressure is too close to the maximum pressure that can be delivered by the filling system, then it will be advisable not to send liquid to the tank. 2.
  • the method then provides for a predetermined pressure (P 0 ) from which it is planned to carry out a degassing of the tank 2.

  • the continuation of the process depends on the quantity of gas withdrawn from reservoir 2 during this degassing operation. If this quantity is large, that is to say greater than a predetermined quantity Q 0 , it is estimated that there is still space in the tank 2 and a new filling step can then be launched.

  • step G1 When the flexible pipe is connected to tank 2, the third valve 22 closes to control the flow of gas leaving tank 2. If a degassing operation (step G1) is planned, then this third valve 22 is opened to allow gas to be withdrawn from reservoir 2.
