Title
(EN) CRYOGENIC FLUID STORAGE TANK
(FR) RÉSERVOIR DE STOCKAGE DE FLUIDE CRYOGÉNIQUE
Abstract
(EN)
The invention relates to a tank for storing a two-phase cryogenic mixture of liquid and gas, comprising a first casing (1), at least one drawing pipe (5, 7), a tank filling circuit, the tank comprising a sensor assembly (12) measuring the pressure in the first casing (1), the tank comprising a pipe (21) for pressurizing the internal casing (1), comprising an upstream end connected to the lower end of the first casing (1) and a downstream end connected to the upper part of the first casing (1), the pressurization line (21) comprising at least one regulating valve (14) and a heater (13), in particular a vaporization heat exchanger. The invention is characterized in that the regulating valve (14) is configured to automatically maintain the pressure in the first casing (1) at a minimum value by ensuring, when the pressure in the first casing (1) is lower than said first value, a circulation of liquid taken from the first casing (1) in the heater (13) and a re-injection of said heated fluid into the first casing (1).
