The introduction of CO2 emissions peaking and neutrality targets bring huge challenges to China’s petroleum and petrochemical industry. However, there is not enough research on the emission characteristics, mitigation technologies assessment and optimization of this industry. This paper constructs an integrated assessment and optimization model for mitigation technologies, which includes the following three parts. Firstly, the model analyzes the emission characteristics based on enterprises’ emissions data. Secondly, the model selects key mitigation technologies and conducts the integrated evaluation based on the emission characteristics. Thirdly, the combination of mitigation technologies for typical enterprises have been optimized. The results show that it is difficult to widely apply emerging mitigation technologies in petroleum and petrochemical industry at present due to safety, cost and other factors; energy saving will still be an important measure for short-term emission reduction. In the long term, the adjustment of energy structure will play an increasingly important role. In addition, the emission composition of different enterprises varies greatly and they should apply different mitigation strategies.
