  • Publication number: 20220026024
    Abstract: Cryogenic fluid storage tank comprising a pipe for drawing off vaporized gas, which pipe is connected to a first casing and comprises a vaporizer and at least one control valve, a first filling pipe connected to the lower portion of the first casing, a second pipe for filling a downstream end connected to the upper portion of the first casing, a distribution valve assembly configured to enable distribution of the fluid from the fluid source in the filling pipes, a pressurization pipe connected to the lower end of the first casing and a second end connected to the upper portion of the first casing and at least one control valve and a heater, the tank further comprising an air vent regulator, the valve assembly for distribution in the filling circuit, the valve for controlling the pressurization pipe, the valve for controlling the drawing-off circuit and the air vent regulator being integrated into the same valve module, which shares at least one valve element.

  • Publication number: 20220026028
    Abstract: The invention relates to a tank for storing a two-phase cryogenic mixture of liquid and gas, comprising a first casing, at least one drawing pipe, a tank filling circuit, the tank comprising a sensor assembly measuring the pressure in the first casing, the tank comprising a pipe for pressurizing the internal casing, comprising an upstream end connected to the lower end of the first casing and a downstream end connected to the upper part of the first casing, the pressurization line comprising at least one regulating valve and a heater, in particular a vaporization heat exchanger. The invention is characterized in that the regulating valve is configured to automatically maintain the pressure in the first casing at a minimum value by ensuring, when the pressure in the first casing is lower than said first value, a circulation of liquid taken from the first casing in the heater and a re-injection of said heated fluid into the first casing.

  • Publication number: 20210372565
    Abstract: The invention relates to a tank for storing a cryogenic mixture of liquid and gas, comprising a first casing, a draw-off pipe for drawing off fluid, which has an upstream end connected to said first casing, a filling circuit comprising a first filling pipe with an upstream end to be connected to a fluid source and a downstream end connected to the lower portion of the first casing, said filling circuit comprising a second filling pipe connected to the fluid source and a downstream end connected to the upper portion of the first casing, wherein the upstream ends of said first and second filling pipes are designed to be connected to the same fluid source simultaneously, and a distribution valve assembly which is configured to allow distribution of the fluid in said filling pipes, wherein the tank comprises a sensor assembly which measures the pressure in the first casing, said distribution valve assembly being configured to automatically adjust the pressure in the first casing, during filling, to a predetermine
