Abstract (en)
[origin: WO2014135271A2] The invention relates to an air separation plant (100), which is designed to obtain a product containing argon by the low-temperature separation of compressed and cooled feed air, wherein the air separation plant (100) comprises a high-pressure column (1), a multi-part low-pressure column having a base segment (2) and a head segment (3), and a multi-part crude argon column having a base segment (4) and a head segment (5), wherein at least one oxygen-enriched flow (d) can be obtained from at least part of the feed air in the high pressure column (1), at least one argon-enriched flow (m) can be obtained from at least part of the oxygen-enriched flow (d) in the low-pressure column, and at least one argon-rich flow (n) can be obtained from at least part of the argon-enriched flow (m) in the crude argon column, and wherein at least one liquid flow (n) can be transferred from a lower region of the head segment (3) of the low-pressure column and from a lower region of the base segment (4) of the crude argon column into an upper region of the base segment (2) of the low-pressure column. The invention further relates to corresponding methods.
