The invention relates to a method and device for producing argon by cryogenic distillation of air. The device for comprises an argon separation column (K), means for sending a gas containing argon andoxygen (ORG) to the argon separation column, means for extracting a fluid (ARG) enriched in argon at the top of the argon separation column, means for extracting a liquid (ORL) enriched in oxygen atthe bottom of the argon separation column and at least two storage tanks (S1,S2,S3,S4,S5,S6), positioned one above the other, each storage tank being connected to two different intermediate levels ofthe argon separation column by two pipes, the two storage tanks being contiguous. 本发明涉及一种用于通过空气的低温蒸馏来生产氩的方法和设备，该设备包括氩分离塔(K)、用于将含有氩和氧(ORG)的气体送至塔的装置、用于在塔顶提取富氩流体(ARG)的装置、用于在塔底提取富氧液体(ORL)的装置和彼此上下定位的至少两个储罐(S1，S2，S3，S4，S5，S6)，每个储罐通过两个管道连接到氩分离塔的两个不同的中间层级，所述两个储罐是接续的。
