Abstract:A process modeling software Petro SIM was used to create an overall simulation of fluid catalytic cracking (FCC) system. Based on the simulation, 7 key variables that affect the distribution of the FCC product were filtered from 15 independent manipulated variables by the mean impact value (MIV) method. Under the premise of ensuring product quality, a multi-objective model of maximizing the mass flow rate both of liquefied petroleum gas (LPG) and gasoline was built. Multi-objective line-up competition algorithm (MOLCA) was applied to solve the optimal problem and then the Pareto front was obtained which revealed the interactional law of LPG, gasoline and diesel mass flow rate. Depending on the market requirement for different products, optimal operation conditions were proposed for optimizing operation and product distribution in FCC system.
