Abstract

Cryosystem for cryogenic liquids which contain small amounts of foreign fluids with higher melting and boiling points, wherein the cryosystem comprises at least one tank, pipelines and assembly units and is used under defined gravitation conditions. The pipelines slope, at least in some areas, toward the tank, and areas of the pipelines and assembly units, from which the cryogenic liquid and the foreign fluids cannot flow back into the tank under the action of gravity, are provided with drain openings and drain lines, which open into the tank or into at least one additional collection tank.
