Abstract

Das Verfahren und der Vorrichtung dienen zur variablen Erzeugung von gasförmigem Drucksauerstoff durch Tieftemperaturzerlegung von Luft in einem Destillationssäulen-System, das eine Hochdrucksäule (5) und eine Niederdrucksäule (6) aufweist. Einsatzluft wird in Form eines Gesamtluftstroms (1) in einem Hauptwärmetauscher (3) abgekühlt. Mindestens ein Teil der abgekühlten Einsatzluft wird in die Hochdrucksäule (5) eingeleitet. Ein erster Sauerstoffstrom (35) aus der Niederdrucksäule (6) wird in flüssigem Zustand auf einen erhöhten Druck gebracht (36), im Hauptwärmetauscher (3) verdampft oder pseudo-verdampft und angewärmt und schließlich als gasförmiges Drucksauerstoffprodukt gewonnen. Ein erster und ein zweiter Teilstrom (12) der Einsatzluft werden vor ihrem Eintritt in den Hauptwärmetauscher (3) auf einen hohen Druck gebracht (9, 10), der mindestens 4 bar höher als der Betriebsdruck der Hochdrucksäule (5) ist. Der erste Teilstrom wird in dem Hauptwärmetauscher (3) verflüssigt oder pseudo-verflüssigt und anschließend in das Destillationssäulen-System eingeleitet (14). Der zweite Teilstrom (16) wird arbeitsleistend entspannt (17) und anschließend in das Destillationssäulen-System eingeleitet (4). In einer ersten Betriebsweise wird eine erste Gesamtluftmenge im Hauptwärmetauscher (3) abgekühlt und eine erste Turbinenmenge wird als erster Teilstrom (16) der arbeitsleistenden Entspannung zugeführt. In einer zweiten Betriebsweise wird ein zweiter Sauerstoffstrom (46) aus einer externen Quelle außerhalb des Destillationssäulen-Systems in flüssigem Zustand in die Niederdrucksäule (6) eingeführt, weniger Gesamtluft (1) im Hauptwärmetauscher (3) abgekühlt weniger Luft der arbeitsleistenden Entspannung (17) zugeführt als in der ersten Betriebsweise.
