Abstract

The invention relates to a container (1) for storing a fluid (F), preferably in the form of a low-boiling liquefied gas, comprising the following: an inner container (20) which has an inner container wall (21) that surrounds an interior of the inner container (20), said interior being designed to receive the fluid (F); an outer container (10) which has an outer container wall (11) that surrounds the inner container (20); an intermediate space (30) provided between the inner container wall (21) and the outer container wall (11); and a connecting piece (50, 60) which is secured to the outer container wall (11) and via which a flow connection to the intermediate space (30) can be established. According to the invention, the connecting piece (50, 60) is surrounded by a housing (100, 100') in order to protect against fire, said housing being secured to the outer container wall (11). The housing (100, 100') surrounds a housing (100) interior (101, 101') in which the connecting piece (50, 60) is arranged, and a fire retardant material (M) is arranged in the interior (101, 101').

Die besagte Isolierung kann dadurch erreicht werden, dass ein den Innenbehälter umgebender Zwischenraum, der durch eine Wandung des Innenbehälters sowie durch eine diese Innenbehälterwandung umschließende Wandung des Außenbehälters begrenzt wird, evakuiert wird, wobei weiterhin zusätzlich ein Material mit möglichst geringer Wärmeleitung in dem Zwischenraum angeordnet sein kann (z.B. in Form einer Schüttung). Sofern ein solches Material verwendet wird, wird die endgültige The said insulation can be achieved by evacuating an intermediate space surrounding the inner container, which is bounded by a wall of the inner container and by a wall of the outer container enclosing this inner container wall, wherein additionally a material with as little heat conduction as possible is arranged in the intermediate space can (eg in the form of a bed). If such a material is used, the final will be
Evakuierung des Zwischenraumes nach einem Einbringen des Materials in den Zwischenraum erzeugt. Evacuation of the gap created after an introduction of the material in the gap.
Weiterhin weisen Behälter der eingangs genannten Art in der Regel einen Stutzen auf, über den eine Strömungsverbindung mit dem Zwischenraum herstellbar ist, so dass der Zwischenraum beispielsweise über diesen Stutzen evakuierbar ist. Furthermore, containers of the type mentioned in the rule on a nozzle, via which a flow connection with the intermediate space can be produced, so that the gap is evacuated, for example via this nozzle.
Nachdem das notwendige Vakuum im besagten Zwischenraum erreicht ist, wird der Stutzen abdichtend verschlossen. Sollte am Kryobehälter oder in unmittelbare Nähe ein Feuer auftreten, so kann es sein, dass diese Dichtung unter der Wärmeeinwirkung versagt und das Isoliervakuum im Zwischenraum des Behälters zerstört wird. Insbesondere bei Kryobehältern für LNG ist die zuverlässige Feuerbeständigkeit wichtig, da bei Versagen des Isoliervakuums flüssiges LNG, welches im Innenbehälter gelagert ist verdampft und somit größere Mengen an Erdgas freigeben werden können. After the necessary vacuum has been reached in said intermediate space, the nozzle is sealingly closed. If a fire occurs at the cryocontainer or in the immediate vicinity, it may be that this seal fails under the action of heat and the insulating vacuum is destroyed in the space between the container. Reliable fire resistance is particularly important in the case of cryogenic containers for LNG, since if the insulating vacuum fails, liquid LNG, which is stored in the inner container, can evaporate and thus release larger quantities of natural gas.
