Abstract

Das Verfahren und die Vorrichtung dienen zur Erzeugung von gasförmigem Druckstickstoff durch Tieftemperaturzerlegung von Luft in einem Destillationssäulen-System, das eine Vorsäule (41), eine Hochdrucksäule (42) und eine Niederdrucksäule (43) aufweist. Die gesamte Einsatzluft wird in einem Hauptluftverdichter (103) verdichtet, in einer Reinigungsvorrichtung (104) gereinigt und in einem Hauptwärmetauscher (2) abgekühlt. Ein erster Teilstrom (11) der abgekühlten Einsatzluft wird gasförmig in die Vorsäule (41) eingeleitet. Ein zweiter Teilstrom (21) der abgekühlten Einsatzluft wird in überwiegend flüssigem Zustand in das Destillationssäulen-System eingeleitet (23, 24). Eine gasförmige Fraktion (51 ) aus dem oberen Bereich der Vorsäule (41) wird in den Verflüssigungsraum eines Vorsäulen-Kopfkondensators (44) eingeleitet. Im Verflüssigungsraum gebildete Flüssigkeit (52) wird als Rücklauf (53) auf die Vorsäule (41) aufgegeben. Eine erste Stickstoffproduktfraktion (65) wird gasförmig aus der Hochdrucksäule (42) abgezogen, im Hauptwärmetauscher (2) angewärmt und als erstes gasförmiges Druckstickstoffprodukt gewonnen. Mindestens ein Teil (23) des zweiten Teilstroms (21) wird in den Verdampfungsraum des Vorsäulen-Kopfkondensators (44) eingeleitet. Ein dritter Teilstrom (34) der abgekühlten Einsatzluft wird arbeitsleistend entspannt (35) und anschließend (36) in den Verflüssigungsraum eines Niederdrucksäulen-Sumpfverdampfers (45) eingeleitet und dort mindestens teilweise verflüssigt. Der verflüssigte dritte Teilstrom (37, 38) wird in die Niederdrucksäule (43) eingeleitet. In dem Verdampfungsraum eines Zwischenverdampfers (46) der Niederdrucksäule (43) wird eine Zwischenflüssigkeit der Niederdrucksäule (43) mindestens teilweise verdampft. In dem Verflüssigungsraum des Zwischenverdampfers (46) wird eine gasförmige Kopffraktion (58) aus der Hochdrucksäule (42) mindestens teilweise verflüssigt und dabei gewonnene Flüssigkeit (59, 60) wird als Rücklauf auf die Hochdrucksäule (42) aufgegeben. Mehr als 35 mol-% werden in Form der ersten Stickstoffproduktfraktion (65), die gasförmig aus der Hochdrucksäule (42) abgezogen wird, im Hauptwärmetauscher (2) angewärmt und als erstes gasförmiges Druckstickstoffprodukt (66) gewonnen.
