Abstract

The pressure in a crude argon column is lower than the pressure in a low pressure column. Recovering argon in an air decomposition plant comprises decomposing an oxygen stream rich in argon from a low pressure column (2) of a rectification column in the crude argon column (5) equipped with conventional plates, packing and/or fillers into crude argon and a first higher boiling liquid residual fraction; cooling the head of the crude argon column thermally coupled to the low pressure column by indirect heat exchange with vaporizing sump liquid relieved to the pressure of the low pressure column, and decomposing the crude argon fed from the head of the crude argon column into a pure argon column into pure argon and a second lower boiling fraction. The pressure in the crude argon column is lower than the pressure in the low pressure column. An Independent claim is also included for an apparatus for recovering argon.
