ABSTRACT:
A method for controlling an integrated cryogenic air separation unit (ASU)/gas turbine system which maintains peak power output in spite of ambient temperature variations. The ratio of air flow to the ASU from a source of supplemental air and a turbine compressor is adjusted to compensate for changes in ambient air temperature and to maintain air flow to the ASU at a level which enables production of the product, a fuel stream is controlled to maintain gaseous output from a combustor at a maximum practical temperature and a flow ratio of waste nitrogen and fuel fed to the combustor is maintained substantially constant.
