Impacts of Pollutant Emissions from Typical Petrochemical Enterprises on Air Quality in the North China Plain
Under the state’s key surveillance, petrochemical industries are considered polluting enterprises. Even though large-scale petrochemical enterprises follow the complete treatment of combustion waste gas, process waste gas, and volatile organic waste gas pollutants, the impact of pollutant emissions...

| description | Under the state’s key surveillance, petrochemical industries are considered polluting enterprises. Even though large-scale petrochemical enterprises follow the complete treatment of combustion waste gas, process waste gas, and volatile organic waste gas pollutants, the impact of pollutant emissions on the regional air quality is unclear. This study used the atmospheric chemical transport model and adopted the subtraction method to simulate the impacts of air pollutant emissions from four typical petrochemical enterprises on regional air quality of the North China Plain. Results indicated that emissions from petrochemical enterprises on surface PM<sub>2.5</sub>, SO<sub>2</sub>, and NO<sub>2</sub> concentrations mainly contributed to the nearby area, particularly SO<sub>2</sub> and NO<sub>2.</sub> The pollution can be controlled within the boundaries of the petrochemical plants. Petrochemical enterprises had a small SO<sub>2</sub> and NO<sub>2</sub> contribution with a maximum of up to 4.65% within a 9 km distance. Emissions from petrochemical enterprises contributed less to surface PM<sub>2.5</sub> concentrations (less than 0.5%) within a 9 km distance. Surface O<sub>3</sub> concentrations driven by petrochemical enterprises did not show near-source distribution characteristics, which were closely related to its complex precursors and secondary reactions. Contributions of petrochemical enterprises to local pollution decreased significantly with the increase in distance. The SO<sub>2</sub> and NO<sub>2</sub> pollution contributions to the North China Plain remained around 0.1–0.2%, with the maximum contribution occurring in January and July. The maximum contribution of PM<sub>2.5</sub> in this region was in April (0.42%) while it was below 0.1% for other months. The pollutant emission from the four typical petrochemical enterprises in the North China Plain had little impact on the concentration of air pollutants in the North China Plain. However, it had a significant impact on the ambient air quality in the region near the enterprise. This study can be useful in analyzing and refining the influence of enterprises on the region. |
