Description
Die Elemente sind starr mit dem Isoliermantel und der Rektifiziersäule verbunden. Nachteilig ist bei einer derartigen starren Befestigung mittels Schraub- oder Schweißverbindungen, daß sie im Betrieb nahezu keine Veränderung der Abmessungen der Rektifiziersäule erlauben, die aufgrund des großen Temperaturunterschiedes zwischen Transport- und Betriebstemperatur auftreten, da die Werkstoffe aufgrund der tiefkalten Betriebstemperatur von ca -170° C schrumpfen. Dies erfordert einen hohen Fertigungs- und Berechnungsaufwand um die Ausdehnung der Anlagenteile zu beherrschen und gegebenenfalls eine Funktionstrennung in Fixierelemente und Transportsicherungselemente, die nach dem Transport entfernt werden müssen.
Hinzu kommt, daß durch die Verspannung der Anlagenteile im Isolationsraum das Gesamtgewicht der Anlage reduziert und der Berechnungsaufwand bezüglich der Ausdehnung der Anlagenteile verringert werden kann.
zwischen dem Lager und der Innenfläche des Isoliermantels als Zwischenlagen angeordnet. Vorzugsweise wird der Isolationsraum mit Isolierwerkstoff, z. B. "Perlite", mit einer Dichte zwischen 40 bis 80 kg/m3, ausgefüllt.
