摘要
利用开路式傅里叶变换红外光谱技术对某300 m×422 m炼化装置区域开展了VOCs排放监测工作,在同等气象条件下完成了上下风向多组分测量;对监测结果应用主因子分析法进行了分析,在基于大气扩散模型的基础上选择特征污染物表征VOCs的方法对该区域VOCs年排放量进行了评估。结果表明,开路式傅里叶变换红外光谱技术能够实现多组分分析,实现区域性监测;该区域上风向背景点与下风向受体点VOCs存在化学组分特征差异,计算得到该区域VOCs年排放量为158 t。
The open-path Fourier transform infrared spectroscopy technology is used to evaluate the VOCs emissions within a 300 meters x 422 meters refining and chemical facilities area. The upwind and downwind multi-component measurements are completed under the same weather conditions. The principal factor analysis method is used to analyze the monitoring results. Based on the atmospheric diffusion models,the method of selecting characteristic pollutants to represent VOCs is used to evaluate the annual emissions of VOCs in this area. Result shows that the multi-component analysis and regional monitoring can be achieved by using open-path Fourier transform infrared spectroscopy technology.There are differences in the chemical components of VOCs between the wind upwind background and the downwind point in this area.The annual emission amount of VOCs from this area is calculated to be about 158 tons.
