| 中文摘要 |
| 为研究淄博市重点工业行业的VOCs排放特征，筛选出9个重点行业，选择各行业代表性企业进行实地调研和采样，分析了不同行业的VOCs排放特征，通过实测法计算了各企业的VOCs排放量，并在此基础上得到本地化排放因子.结果表明，不同行业的VOCs排放特征存在一定差异，多数行业以烷烃、卤代烃为主；乙烷、乙炔、氯乙烷类（包括1，1-二氯乙烷、1，1，1-三氯乙烷）以及氟利昂类（氟利昂12或氟利昂114）为大多数行业均含有的主要特征物种；分环节排放量计算结果显示，设备动静密封点泄漏、有机液体装卸挥发损失、有机液体储存与调和挥发损失以及工艺有组织排放为不同类型石化行业的VOCs主要排放环节，排放量占比均达到40%以上；合成橡胶与炼钢行业的VOCs本地化排放因子与已有规范中的推荐值相近，其余行业则存在较大差距. |
| 英文摘要 |
| To study the emission characteristics of volatile organic compounds (VOCs) in Zibo, nine key industries and their representative enterprises were selected to conduct a field investigation and measurement. The emitted VOC characteristics in different industries were analyzed. Based on measurement data, the emissions of VOCs from all monitored enterprises were calculated to obtain the localization emission factors. The results showed that different industries exhibited some differences in VOCs components, and the major VOCs components were alkane and halo hydrocarbon. Ethane, acetylene, chloromethane (conclude 1,1-dichloroethane, 1,1,1-trichloroethane), and Freon (Freon 12 or Freon 114) were the characteristic species in most industries. The results indicated that the major VOCs emission links in different types of petrochemical industries were equipment leakage, loading volatilization, storage volatilization losses, and organized discharge, which accounted for more than 40% of emissions. Local emission factors of VOCs calculated in the synthetic rubber and steel manufacturing industries were close to the recommended values in the guide, whereas there were large gaps in other industries. |
