Abstract:
Based on the emission inventory of independent coking industry in Shandong Province in 2018, Business As Usual scenario (BAU-2018, BAU-2025) and Emission Reduction Optimization scenario (ERO-2018, ERO-2025) were set up, and PM10, SO2, NOx, PM2.5, CO2 emission reduction potential were analyzed respectively. The CALPUFF model was used to simulate the pollution of SO2, NOx, PM10 and PM2.5 in the independent coking industry in Shandong Province under different scenarios. The results showed that in the ERO-2025 scenario, the emissions of PM10, SO2, NOx, PM2.5 and CO2 would be reduced by 68.76%, 50.03%, 72.73%, 67.67% and 21.65%, respectively, compared with that of BAU-2018. The average contribution concentration of SO2, NOx, PM10 and PM2.5 decreased by 50.81%, 73.14%, 68.67% and 68.09%, respectively. The full implementation of ultra-low emission standards has a significant effect on pollutant emission reduction, and the collaborative emission reduction potential of pollutants and CO2 is huge.
