摘　　要：为进一步提升开路式傅里叶变换红外光谱技术(OP-FTIR)对VOCs排放量核算结果的准确性,从监测光路布设以及排放量核算方法方面开展研究,结合箱体模型原理给出了一种基于OP-FTIR多光路同步监测与面域重构技术的VOCs核算办法,并于华北地区某油库开展应用。研究结果表明:结合多光路同步监测方案,基于三阶二维高斯函数的平滑基函数最小化算法在面浓度重构方面具有较好的准确性,也更适用于无组织排放显著的石化企业生产装置/储罐排放量核算;经OP-FTIR现场监测与核算,该罐区内某原油储罐A#挥发性有机物年排放量为26.1 t,结果合理。In order to further improve the accuracy of the Open-path Fourier Transform Infrared Spectrometry(OP-FTIR)for VOCs emission,the monitoring optical path layout and emission accounting method were studied.Combined with the box model principle,a VOCs accounting method based on OP-ETIR multi-optical path synchronous monitoring and area reconstruction technology was proposed and applied in oil depot in North China.Technology has been applied in calculation of VOCs emission in the petrochemical industry.The research results showed that:firstly,combined with the multi-optical simultaneous monitoring scheme,the smooth basis function minimization algorithm based on the third-order two-dimensional Gaussian function had good accuracy in the area integral concentration,and it was more suitable for petrochemical production equipment/storage tanks with significant fugitive emissions;second,with OP-FTIR on-site monitoring and accounting,the annual VOCs emission of a crude oil tank A#in the oil depot was 26.1 t,and the result was reasonable.
