Abstract

Das Verfahren und die Vorrichtung dienen zur Gewinnung von Drucksauerstoff und Druckstickstoff durch Tieftemperaturzerlegung von Luft in einem Destilliersäulen- System zur Stickstoff-Sauerstoff-Trennung, das mindestens eine Hochdrucksäule (8) und eine Niederdrucksäule (460) aufweist, wobei die Niederdrucksäule (460) über einen als Kondensator- Verdampfer ausgebildeten Hauptkondensator (461) mit der Hochdrucksäule (8) in wärmetauschender Verbindung steht. Einsatzluft wird in einem Luftverdichter (2) verdichtet. Die verdichtete Einsatzluft (6, 734, 802, 840) wird in einem Hauptwärmetauscher (20) abgekühlt und mindestens teilweise in die Hochdrucksäule (8) eingeleitet. Eine sauerstoffangereicherte Flüssigkeit (462, 465) wird aus der Hochdrucksäule (8) entnommen und der Niederdrucksäule (460) an einer ersten Zwischenstelle zugeführt (464, 467, 906). Eine stickstoffangereicherte Flüssigkeit (468, 470) wird aus der Hochdrucksäule (8) und/oder dem Hauptkondensator (461) entnommen und auf den Kopf der Niederdrucksäule (460) aufgegeben. Ein flüssiger Sauerstoffstrom (11, 12) wird aus dem Destilliersäulen-System zur Stickstoff- Sauerstoff-Trennung entnommen, in flüssigem Zustand auf einen erhöhten Druck gebracht (13), unter diesem erhöhten Druck in den Hauptwärmetauscher (20) eingeleitet, im Hauptwärmetauscher (20) verdampft oder pseudo-verdampft und auf etwa Umgebungstemperatur angewärmt und schließlich als gasförmiges Drucksauerstoffprodukt (14) gewonnen. Ein Hochdruck-Prozessstrom (34, 734) wird in dem Hauptwärmetauscher (20) in indirekten Wärmeaustausch mit dem Sauerstoffstrom gebracht und anschließend entspannt (36, 38; 736, 738) wird, wobei der entspannte Hochdruckstrom (37, 737) mindestens teilweise in flüssigem Zustand in das Destilliersäulen-System zur Stickstoff-Sauerstoff-Trennung eingeleitet. Ein gasförmiger Kreislaufstickstoffstrom (18, 19) wird aus der Hochdrucksäule abgezogen wird und mindestens zum Teil (21) in einem Kreislaufverdichter (22) verdichtet. Ein erster Teilstrom (45, 46; 244, 242, 230; 845, 846) des Kreislaufstickstoffstroms wird aus dem Kreislaufverdichter (22, 322) entnommen, in dem Hauptwärmetauscher (20) abgekühlt, in dem Sumpfverdampfer (9, 209) der Hochdrucksäule (8) in indirektem Wärmeaustausch mit der Sumpfflüssigkeit der Hochdrucksäule (8) mindestens teilweise verflüssigt und in das Destilliersäulen-System zur Stickstoff-Sauerstoff- Trennung zurückgeleitet. Ein zweiter Teilstrom des Kreislaufstickstoffstroms wird stromaufwärts und/oder stromabwärts des Kreislaufverdichters und/oder von einer Zwischenstufe des Kreislaufverdichters unter einem Produktdruck (P, P1, P2, P3, P4) abgezweigt und als Druckstickstoffprodukt (27, 29, 53, 564, 565) gewonnen. Der Kreislaufverdichter (22, 322) ist als warmer Verdichter ausgebildet und wird mittels externer Energie angetrieben.
