A method an apparatus for separating air in which an oxygen containing vapor stream is removed from a single column nitrogen generator and then divided into two subsidiary streams. The two subsidiary streams are condensed and then combined for stripping within a stripping column to produce ultra-high purity liquid oxygen as a column bottoms.

The other of the two subsidiary streams is condensed within a head condenser used in connection with the nitrogen stripping column.
