Abstract

Das Verfahren und die Vorrichtung dienen zur Tieftemperaturzerlegung von Luft in einem Destilliersäulen-System, das mindestens eine Hochdrucksäule (11) und eine Niederdrucksäule (12) aufweist. Das Verfahren weist eine hohe Vorverflüssigung von 30 % oder mehr auf. Einsatzluft wird in das Destilliersäulen-System eingeleitet. Das Destilliersäulen-System weist außerdem eine Vorsäule (10) auf, deren Betriebsdruck höher als der Betriebsdruck der Hochdrucksäule (11) ist. Ein erster Teilstrom (1) der Einsatzluft wird in die Vorsäule (10) eingeleitet. Die Vorsäule (10) weist einen Kopfkondensator (14) auf, der als Kondensator-Verdampfer mit Kondensationsraum und Verdampfungsraum ausgebildet ist. Eine gasförmige Fraktion (30, 31) aus dem oberen Bereich der Vorsäule (10) wird in den Kondensationsraum des Kopfkondensators (14) eingeleitet. Im Kondensationsraum gebildete Flüssigkeit (6) wird mindestens teilweise als Rücklauf (7) auf die Vorsäule (10) aufgegeben. Ein zweiter Teilstrom (2a; 2b) der Einsatzluft wird in den Verdampfungsraum des Kopfkondensators (14) eingeleitet.
