Abstract

Die Erfindung betrifft ein Verfahren zur Tieftemperaturzerlegung von Luft unter Verwendung einer Luftzerlegungsanlage mit einem Destillationssäulensystem (100), das eine erste, eine zweite, eine dritte und eine vierte Trenneinheit (110-140) aufweist. In die erste Trenneinheit (110) wird verdichtete und abgekühlte Luft eingespeist wird, die erste Trenneinheit (110) wird auf einem ersten Druckniveau von 4 bis 9 bar Absolutdruck betrieben, die zweite, die dritte und die vierte Trenneinheit (120-140) werden auf einem zweiten Druckniveau von 1 bis 3 bar Absolutdruck betrieben, mittels der ersten Trenneinheit (110) werden eine an Sauerstoff angereicherte und an Stickstoff abgereicherte, Argon enthaltende erste Sumpfflüssigkeit und ein an Stickstoff angereichertes und an Sauerstoff abgereichertes erstes Kopfgas gebildet, die erste Sumpfflüssigkeit wird zumindest teilweise in die vierte Trenneinheit (130) überführt, das erste Kopfgas wird zumindest teilweise verflüssigt und auf die erste Trenneinheit (110) zurückgeführt, mittels der zweiten Trenneinheit (120) werden eine sauerstoffreiche zweite Sumpfflüssigkeit und ein an Argon angereichertes zweites Kopfgas gebildet, das zweite Kopfgas wird zu einem ersten Anteil in die dritte Trenneinheit (130) und zu einem zweiten Anteil in die vierte Trenneinheit (140) überführt, mittels der dritten Trenneinheit (130) wird zumindest der überwiegende Teil des Argons, das in einer dem Destillationssäulensystem (100) insgesamt zugeführten Luftmenge enthalten ist, abgetrennt und mittels der dritten Trenneinheit (130) wird ein flüssiger Rücklauf auf die zweite Trenneinheit (120) bereitgestellt, mittels der vierten Trenneinheit (140) werden eine vierte Sumpfflüssigkeit und ein viertes Kopfgas gebildet werden, und die vierte Sumpfflüssigkeit wird zumindest teilweise auf die zweite Trenneinheit (120) zurückgeführt. Die zweite Trenneinheit (120) weist 10 bis 50 theoretische Böden auf, die dritte Trenneinheit (130) weist 10 bis 60 theoretische Böden auf, die dritte Trenneinheit (130) ist oberhalb der zweiten Trenneinheit (120) angeordnet und die vierte Trenneinheit (140) ist neben der ersten Trenneinheit (110) angeordnet. Die dritte Trenneinheit (130) öffnet sich in einem unteren Bereich gegenüber einem oberen Bereich der zweiten Trenneinheit (120), oder die dritte Trenneinheit (130) ist über Rohrleitungen, die zwischen einem oberen Bereich der zweiten Trenneinheit (120) und einem unteren Bereich der dritten Trenneinheit (130) verlaufen, mit der zweiten Trenneinheit (120) verbunden. Eine entsprechende Anlage (200) ist ebenfalls Gegenstand der vorliegenden Erfindung.
