Abstract: Based on membrane jet emulsification theory, micro-explosion theory and molecular aggregation and depolymerization theory, SINOPEC Engineering Incorporation and Nanjing Gongda Fuding Energy Technology Co., Ltd. developed FCC feedstock heterogeneous emulsification and high-efficiency atomization technologies, which could significantly enhance the atomization effect of RFCC feed and improve reaction product distribution. The technology has been successfully applied to the 2.8 MM TPY RFCC unit of SINOPEC Jingmen Branch. The calibration results show that the LPG and gasoline yields of the unit are increased by 0.66 percentage points and 0.46 percentage points respectively, the total yield of LPG and gasoline is increased by 1.12 percentage points, the diesel yield is reduced by 2.12 percentage points, and the diesel gasoline ratio of the unit is reduced from 0.360 to 0.308, which significantly improves the economic benefits of RFCC unit. Heterogeneous emulsification and high-efficiency atomization technologies have little effect on the properties of gasoline, diesel and slurry in FCC unit.
