ABSTRACT:
Process for the temperature stratification-free storage of a cryogenic liquid in a thermally insulated tank under gravitation conditions or under gravitation and movement conditions, which generate a liquid volume with a clearly limited, unmoving or only moderately moving liquid level as well as with a gas space located above it in the storage volume of the tank. Liquid is pumped off from the area near the bottom of the tank continuously or at time intervals, it is fed into the area of the gas space, and it is directed vertically or at an acute angle toward the liquid level there in the form of at least one high-energy jet.
