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.
Dispositif de régulation de système réunissant un appareil de séparation d'air et une turbine à gaz, permettant de maintenir un rendement maximal en dépit de variations de la température ambiante. Les proportions relatives d'air d'alimentation de l'appareil de séparation provenant d'une source d'appoint et du compresseur de la turbine sont réglées de manière à compenser les fluctuations de la température de l'air ambiant et à maintenir un niveau d'alimentation en air de l'appareil qui permette la production du constituant recherché. L'alimentation en combustible de la chambre de combustion est réglée de manière à maintenir les gaz de combustion à la plus haute température possible, et les proportions relatives d'azote récupéré et de combustible dans l'alimentation de la chambre de combustion sont maintenues pratiquement constantes.
