地面浓度反推法计算石化企业无组织排放源强

对某石化企业储罐区和原油脱酸装置区的无组织排放非甲烷总烃进行监测，对监测数据进行Pearson相关分析，运用地面浓度反推法计算源强。实验结果表明：原油脱酸装置区各采样线浓度间的相关性好，反推出的源强较为准确，50，100，150 m采样线的反推源强非常接近，分别为21.68，21.60，19.76 t/a；而储罐区监测浓度的相关性不佳，该区域的非甲烷总烃无组织排放源可能不单一，不适用地面浓度反推法计算其源强。

Accounting of Fugitive Emission Source Intensity in Petrochemical Enterprises by Ground Concentration Reverse Calculation Method

The concentrations of fugitive non-methane hydrocarbon (NMHC) were monitored respectively in the area of storage and crude oil deacidification in a refinery. The monitoring data were analyzed with Pearson correlation coefficient and the source intensity was accounted by ground concentration reverse calculation method. The experimental results show that：The concentrations in the crude oil deacidification area are highly correlated leading to precise reverse calculation results of source intensity；The calculated source intensities with the concentration data of sample line 50，100，150 m are similar，which are 21.68，21.60，19.76 t/a respectively；The correlation coefficients in the storage area are poor，it indicates that NMHC may not come from the same source and the concentration data are not suitable for source intensity calculation
