Beschreibung
Zusammenfassung:	Low temperature air decomposition plant comprises several modules consisting of a heat exchanger unit, a pressure column (2), and a low pressure column (3); and cold boxes formed as a main box and a secondary box. The secondary box contains at least one of the modules. Preferred Features: At least one or no module is present in the module. A pure argon rectification unit is provided in the plant and comprises partial columns (6, 7), a pure argon line, a pump (11) for recycling reflux liquid from the sump to the second partial column, and an argon head condenser (9). The main box is a pure argon column (8).
