ABSTRACT:
A fluid catalytic cracking unit (FCCU) is controlled in such a manner that load is automatically shifted from the wet gas compressor to the air blower for the catalyst regenerator if the loading on the wet gas compressor becomes a limiting factor on the yield of a desired product from the FCCU. Also, the preheat temperature for the feed flowing to the reactor is automatically increased if the desired temperature in the reactor cannot be maintained by increasing catalyst flow to the reactor without exceeding an air blower limitation. This automatic load shifting provides for a substantially maximum production of a desired product without exceeding a process limitation.
