An evaluation method for synergistic effect of air pollutants and CO2 emission reduction in the Chinese petroleum refining technology

The screening and evaluation of co-control technologies for pollution reduction and carbon mitigation represent a crucial prerequisite for researching pathways toward pollution and carbon reduction within petroleum refining industry. A systematic assessment method for technology synergies in pollution reduction and carbon mitigation remains deficient in China. In this study, we propose a method for evaluating the synergistic effects of technologies in pollution reduction and carbon mitigation in the petroleum refining industry. This model evaluates the synergistic control efficacy of technologies from multiple perspectives, including pollution-carbon synergy, synergistic reduction of pollutant-carbon emissions, cost-benefit analysis, and environmental benefits. The developed methodology is validated through its application to typical petroleum refining technology. The results confirm the synergistic benefits of pollution and carbon reduction through five petroleum refining technologies. With the increase in carbon trading prices, bio-jet fuels (T1) and microalgae carbon sequestration (T5) technologies have greater application potential. This study provides a scientific basis and theoretical support for the realization of collaborative control of carbon pollution in the petroleum refining industry.
