Abstract
An object of the present invention is to provide an argon column for an air separation unit in which the height of the distillation column is reduced without reducing distillation performance. The present invention provides an argon column for an air separation unit including an upper section and a lower section; the upper section and the lower section both have a bed having the same bed length within the same section; the upper section length is 72% or less of the total bed length; and the upper bed length is 1.25 times or more than the lower bed length.
Claims5
An argon column for an air separation unit comprising a high-pressure column, a low-pressure column, and an argon column, that is a structured packed column using structured packing materials, and that produces an argon product using a fluid supplied from a middle portion of the low-pressure column as a raw material;
- wherein the argon column comprises an upper section and a lower section;
- wherein the upper section and the lower section both have a bed having the same bed length within the same section;
- wherein the upper section length is 72% or less of the total bed length;
- and
- wherein the upper bed length is 1.25 times or more than the lower bed length.
