Abstract

In einer Einrichtung zum Zerlegen von Luft, insbesondere unter Verwendung eines Tieftemperaturrektifikationsverfahrens, in welcher die Luft verdichtet, gekühlt und expandiert und/oder mit Molekularsieben (10) gereinigt wird und Sauerstoff und Stickstoff sowie gegebenenfalls Edelgase gesondert über Produktgasleitungen ausgebracht werden, ist an eine Produkgasleitung (30) wenigstens eine Zweigleitung (31) angeschlossen, welche über einen Wärmetauscher (9) geführt ist. Weiters sind wenigstens zwei Speicher (7,12) für zwei voneinander verschiedene verflüssigte Gase vorgesehen und das aus der Produktgasleitung (30) abgezweigte Produkt wird durch Abkühlen verflüssigt und gespeichert, wobei die Abkühlung im Wärmetauscher (9) durch das jeweils andere verflüssigte Gas erfolgt und wobei wenigstens eine Rückführungsleitung (32) zwischen einem Speicher (7) für verflüssigtes Produktgas und der Produktgasleitung (30) vorgesehen ist, wodurch die Vorteile eines Wechselspeicherbetriebes erzielbar sind.
Vorzugsweise ist eine Zweigleitung (33) der Produktgasleitung (30) über eine Expansionsturbine (18) geführt.
