ABSTRACT:
A control system for a fluid catalytic cracking unit is provided in which either the wet gas compressor or the air blower is selected for base loading. After the device selected for base loading has been base loaded, load is shifted to the device which was not base loaded. The feed flow rate is forced to continue to increase until both the wet gas compressor and the air blower are loaded so as to substantially maximize the production of the desired product.
