Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Gewinnung von Argon, bei dem verdichtete, vorgereinigte und abgekühlte Luft in einem Rektifiziersystem mit mindestens einer Rektifiziersäule (1;2) und einer Rohargonsäule (5) zerlegt wird, wobei ein aus der Niederdrucksäule (2) der Rektifiziersäule abgezogener argonhaltiger Sauerstoff-strom (3) in einer Rohargonsäule (5) in Rohargon und in eine erste schwerersiedende flüssige Restfraktion (13) und das aus dem Kopf der Rohargonsäule (5) in eine Reinargon-säule (16) eingeleitete Rohargon (15) in Argon-Stickstoff-Gemisch (17) und in Reinargon (18) zerlegt wird. Erfindungsgemäß kann dadurch, dass die Rohargon-Rektifikation (5) in der Rohargonsäule (5) unter einem Druck von etwa 0,9 bis 1,1bar erfolgt, die Anzahl der Rektifikationseinrichtungen in Form von konventionellen Böden und/oder geordneten Packungen und/oder Füllkörpern in der Rohargonsäule (5) wesentlich verringert werden, wodurch eine kostengünstige Gewinnung von Argon mit 0,1 bis 10ppm Restsauerstoffgehalt in allen bekannten Luftzerlegungsanlagen möglich ist.
