Abstract

A method is provided for production of gaseous oxygen at moderate pressures by splitting a main air feed (2) into at least three separate streams (3, 4, 6), with the first stream (3) being fed to a heat exchanger (10) and then a column system (20) for rectification; the second stream (4) being further compressed in a warm booster (30), partially cooled in the heat exchanger, expanded in a turbine (35) coupled to the warm booster and then fed to the column system; the third stream (6) being expanded in a warm expander (40) before being introduced to the heat exchanger and introduced to the column system. In certain embodiments, substantially all of the main air feed is eventually introduced to the column system for rectification, resulting in reduced sizing of a main air compressor and improved product recoveries.
