The present invention relates to an improved cryogenic process for the separation of air to produce an oxygen product and a nitrogen product. The present invention employs a distillation column system with three distillation columns, a low pressure column, a medium pressure column and a high pressure column. The improved three column distillation system process comprises: (a) producing an oxygen product with a product purity of less than 98% purity oxygen and producing no argon product; (b) producing a gaseous nitrogen product which represents greater than 35% of the feed air and which is removed from the medium and/or high pressure columns; (c) recovering a major portion of the oxygen product from the low pressure column; and (d) condensing at least a portion of the high pressure nitrogen overhead from the high pressure column by heat exchange against a liquid stream in the medium pressure column and utilizing at least a portion of the condensed portion to provide reflux to the high pressure column.
