ABSTRACT:
An air supply system for the catalyst regeneration zone of a fluidized catalytic cracking unit also supplies a pressurized air stream to the turbine of an electrical generating plant. The compressor which produces the pressurized air stream is driven by passing the flue gas of the regeneration zone through a power recovery expander. Preferably, the pressurized air stream is first heated by heat exchange against the turbine effluent and then admixed with hot gas from separate turbin-type gas generators prior to being passed into the turbine. This provides a very practical and relatively low-cost cogeneration process.
