Abstract:

The development and implementation process of the 3.0 Mt/a wax oil catalytic cracking unit optimization project of Zhejiang Petrochemical Co., Ltd. was introduced. Based on the rigorous mechanism modeling technology, the ROMeo software package was used to develop the Real-time Optimization (RTO) system. After calibration testing, the use of the RTO system resulted in a 0.15 percentage point decrease in stable gasoline yield, a 0.60 percentage point increase in diesel yield, a 0.07 percentage point increase in LPG yield, and a 0.52 percentage point increase in total light oil yield. It is estimated that the annual economic benefits will increase by nearly 40 million RMB. The results show that, with the support of the advanced process control system, this RTO system can maximize the total light oil yield while ensuring the stable and safe operation of the unit, bringing significant economic benefits to the enterprise.
