【摘要】：为量化石化行业各环节VOCs排放影响,在天津临港化工园区开展石化行业VOCs排放特征调查工作,以石化企业BS为例,对其有组织、无组织及厂界、敏感点排放的物质组分及其浓度进行定性定量分析,得到企业的分环节排放特征及排放清单.结果显示,有组织排放源、装置区、储罐区、集水池共检出25种物质,主要为烷类、烯烃类和醇类,其特征污染物为正癸烷、正壬烷、正辛烷及其异构体、正庚烷及其异构体、甲醇、丙烷;有组织排放源及装置区、储罐区、集水池4个环节排放量依次为8.70、268.42、120.04、0.0003t,以产品产量计,对应的排放因子分别为0.3631、0.1624、0.0118、4.06×10~(-7)kg/t;通过相关性分析(p0.01),装置区与企业厂界浓度水平显著相关,敏感点与BS企业储罐区浓度水平高度相关,可见无组织排放对环境影响显著.
[Abstract]:In order to quantify the effect of VOCs emission in various links of petrochemical industry, the investigation of VOCs emission characteristics of petrochemical industry was carried out in Tianjin Lingang Chemical Industry Park. Taking the petrochemical enterprise BS as an example, it was organized, unorganized and unorganized. Qualitative and quantitative analysis was carried out on the components and concentrations of the substances emitted from sensitive points, and the emission characteristics and emission inventory of the enterprises were obtained. The results showed that 25 substances, mainly alkanes, alkenes and alcohols, were detected in organized emission sources, unit areas, storage tanks and water pools. The characteristic pollutants were decane, n-nonane, n-octane and its isomers, n-heptane and its isomers. The emissions of methanol, propane, organized emission source and unit area, storage tank area and catchment pool are 8.70268.42120.040.0003t, respectively. The corresponding emission factors were 0.3631 (0.1624) 0.0118N 4.06 脳 10 ~ (-7) kg/t; respectively. Through correlation analysis (p0.01), the plant area was significantly correlated with the level of plant boundary concentration, and the sensitive point was highly correlated with the concentration level of BS enterprise storage tank area. It can be seen that unorganized emission has a significant impact on the environment.
