Abstract: The fluid catalytic cracking unit has always been a crucial and key unit in oil refining enterprises. With the development of processes and process control technologies, the progress of fluid catalytic cracking optimization technologies has also become a symbol of the key intelligent technological progress. The control technology of the catalytic cracking process is implemented in a stepwise manner through conventional control, advanced control and online optimization control technologies,in which good conventional control is not only conducive to improving the automatic control rate of the unit, but also serves as the foundation of advanced control. The successful application of advanced control is, in turn, the prerequisite for online optimization technologies. An accurate model of fluid catalytic cracking can greatly improve the performance of optimization control, and its combination with artificial intelligence technologies has laid a cornerstone for realizing the overall intelligent prospects of enterprises.
