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.
