Abstract
An air separation plant for obtaining product containing argon by low temperature separation of compressed, cooled feed air. The air separation plant comprises a high-pressure column, a multi-part low-pressure column having a base segment and a head segment and a multi-part crude argon column having a base segment and a head segment. An oxygen-enriched flow is obtained from part of the feed air in the high pressure column, an argon-enriched flow is obtained from part of the oxygen-enriched flow in the low-pressure column, and an argon-rich flow is obtained from part of the argon-enriched flow in the crude argon column. Liquid flow is transferred from a lower region of the head segment of the low-pressure column and from a lower region of the base segment of the crude argon column into an upper region of the base segment of the low-pressure column.
