摘要
目前,普遍采用公式法核算罐区VOCs排放量,受核算参数取值的影响导致排放量结果差别较大,为了更准确地获得罐区VOCs排放量,基于开放光路傅里叶变换红外光谱分析技术(Open Path Fourier Transform Infrared Spectrometry,OP-FTIR)开展了罐区VOCs排放监测技术研究。以某石化企业4个储罐组成的独立罐区为研究对象,利用OP-FTIR现场实测法连续采集了罐区四周、罐区空间共计7条光路的VOCs体积分数和气象数据,通过质量通量法计算了VOCs排放量。结果表明:该罐区VOCs排放的体积分数平均值为59.8×10^-9,排放量为48.21 t/a(以8760 h计)。该技术为科学核算罐区VOCs排放量提供了一种新方法。(图4,表1,参17)
At present,the formula method is commonly used to calculate the VOCs emission from the tank farm,but the results varies greatly with the values of the calculation parameters adopted.In order to more accurately capture the VOCs emission data from the tank farm,the VOCs emission monitoring technology for tank farm was studied based on the Open Path Fourier Transform Infrared Spectrometry(OP-FTIR)field measurement method.An independent tank farm composed of 4 tanks in one petrochemical enterprise was taken as the research object,the VOCs volume fraction and meteorological data of a total of 7 light paths around the tank farm and within the tank farm space were continuously acquired based on OP-FTIR field measurement method,and the VOCs emission was calculated by mass flux method.The results show that the average volume fraction of VOCs emitted from the tank farm is 59.8×10^-9,and the emission is 48.21 t/a(calculated as 8760 hours per year).This technology provides a new method for scientific calculation of VOCs emission from tank farm.(4 Figures,1 Table,17 References)
