The invention relates to a cryogenic unit comprising: a cryogenic tank; a receptacle; a pipe comprising: a first end connected to the cryogenic tank; a second end; a first longitudinal portion; a second longitudinal portion; a bend between the first portion and the second portion; a connecting flange situated between the bend and the second end, wherein the cryogenic unit further includes: an item of fluidic equipment comprising an inlet end; and an outlet end and configured to be mounted removably inside the receptacle.

Cryogenic unit

Cryogenic tank for storing liquefied fluid, having an inner shell delimiting a storage volume for liquefied fluid and an outer shell arranged in a spaced manner around the inner shell, the space between said inner and outer shells having a thermal insulation, a first mechanical connection having a first support wall of truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell, wherein a second mechanical connection has a second support wall of truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell.

Cryogenic tank for storing liquefied fluid

A device for storing and transporting liquefied gas, including a first inner reservoir extending in a longitudinal direction, a second outer reservoir, the device having a system for holding the first reservoir in the second reservoir having a first rigid connection between the first reservoir) and the second reservoir at a first longitudinal end, and, at a second longitudinal end of the device, a mechanism for suspending the first reservoir inside the second reservoir having an assembly of tie rods, a first end of the tie rods being attached to a sheath that is secured to the first reservoir via a washer(s) and nut assembly, these being fitted around the tie rod, a second end of the tie rods being attached to a sheath that is secured to the second reservoir via a washer(s) and nut assembly.

Device for storing and transporting liquefied gas

Mobile cryogenic tank for transporting cryogenic fluid, notably liquefied hydrogen or helium, comprising an internal shell intended to contain the cryogenic fluid, an external shell arranged around the internal shell and delimiting a space between the two shells, said space containing a thermal insulator, the first shell having a cylindrical overall shape extending along a central longitudinal axis (A), when the tank is in the configuration for transport and use, the central longitudinal axis (A) being oriented horizontally, the tank comprising a set of temperature sensors measuring the temperature of the fluid in the internal shell, characterized in that the set of temperature sensors is situated on the external face of the internal shell and measure the temperature of said shell, the set of temperature sensors comprising a lower sensor positioned at the lower end of the internal shell situated below the central longitudinal axis (A), the set of temperature sensors further comprising a plurality of intermediate sensors distributed over two lateral faces of the internal shell on each side of the central longitudinal axis (A), the plurality of intermediate sensors being distributed vertically between the lower end of the internal shell situated below the central longitudinal axis (A) and the upper end of the internal shell situated above the central longitudinal axis (A).

Mobile cryogenic tank and provisioning method

Vehicle for delivering inflammable fluid comprising a tractor unit and a tank mounted on a support, the vehicle including a fluid circuit connected to the tank that includes a set of pneumatic valves. The vehicle includes an electrical circuit having at least one electrical component and an electricity source connected to the electrical circuit via at least one port for connecting to a connection interface. A cover moves between a first position blocking access to the connection port(s) to prevent the electrical connection between the electricity source and the electrical circuit and a second position not blocking access to the connection port(s) to enable the electrical connection between the electricity source and the electrical circuit. The vehicle includes a switch connected to the fluid circuit switchable between a first state enabling the operation of the set of pneumatic valves to allow filling or draining and a second state preventing the operation of the set of pneumatic valves to prevent filling or draining. In its first position, the movable cover switches the switch or allows it to is be switched to its first state. When the movable cover is in its second position, the switch is automatically switched to its second state.

Vehicle for delivering inflammable fluid

Station for supplying a flammable fluid fuel comprising a first cryogenic tank () for storing fuel in the form of a cryogenic liquid, a second cryogenic tank () for storing an inert gas, a cooling circuit () in a heat-exchange relationship with the first tank (), the cooling circuit () comprising an upstream end connected to the second cryogenic tank () for drawing cryogenic fluid from the second cryogenic tank () in order to give up frigories from the fluid of the second cryogenic tank () to the first tank (), the station comprising a circuit () for withdrawing fluid derived from the second tank (), characterized in that the cooling circuit comprises two pipes () comprising an upstream end connected to the second tank (), the two pipes () each being provided with a respective exchanger () housed in the first tank (), the two exchangers () being respectively situated in the upper and lower parts of the first tank.

Station and method for supplying a flammable fluid fuel

An installation for the storage of a liquified gas under pressure in a pressure chamber. The installation includes a closed pressure resistant chamber to contain the liquid. The container has a wall whose thickness e is determined by computations taking into account parameters associated with a pressure P within the chamber and a temperature T <&minus;50&deg; of the wall of the chamber. The installation further includes a device to indicate a magnitude G of a temperature T of the chamber wall and a device to indicate a magnitude G&prime; representative of the computation temperature T . The installation also includes a device to compare the magnitudes G and G&prime;, and a device to lower the pressure to a value P below the computed pressure P if as a result of the comparison, T is greater than T .
