摘要
The invention relates to a column for separating air by means of cryogenic distillation, said column comprising a shell and at least four distillation segments, including at least a first intermediate distillation segment of the low-pressure column, which is surrounded by an auxiliary shell around which a space is defined that is divided into a lower section and an upper section along the radius of the column, the intermediate segment(s) being located in an intermediate part of the low-pressure column, the capacity of the first intermediate segment being greater than that of at least one adjacent segment, and an opening being disposed in the shell between two adjacent segments, which opening can be sealed if the column is to form part of an argon production device.
