摘要
文章以西北某石化公司180万t汽油国V质量升级项目为例,预测分析项目运行期加热炉烟气中SO_2分别在简单地形、90 m×90 m分辨率和30 m×30 m分辨率3种地形数据条件下大气污染扩散特征。结合项目运行期监测数据对模式在3种地形条件下的预测结果进行相关性分析。结果表明:模式在30 m×30 m分辨率复杂地形条件下获得的预测结果与监测值的相关性最好,其预测结果更能反映项目运行期大气污染物的扩散特征。
Taking a petrochemical corporation with 180 million tons of gasoline in Nation standard V quality upgrade project in northwestern China as an example,the paper forecasted and analyzed the atmospheric pollution diffusion characteristics of project operation period of heating furnace flue gas SO2,respectively,under the condition of simple terrain,90 m × 90 m resolution and 30 m × 30 m resolution. The correlation analysis of the monitoring data during the project operating period was carried out in three different terrain conditions. The results showed that the model correlation was the best in 30 m × 30 m resolution of complex terrain conditions between predicted results and the monitoring value,and the prediction results could reflect the diffusion characteristics of atmospheric pollutants during the project operation period.
