Abstract
A method for controlling production of high pressure gaseous oxygen in a cryogenic air separation unit that uses a high pressure gaseous oxygen bypass together with adjustments to the split of the incoming compressed and purified air between the boiler air circuit and the turbine air circuit such that the volumetric ratio of the boiler air stream to the turbine air stream is reduced to between about 0.15:1 and 0.35:1.
