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.
为研究淄博市挥发性有机化合物（VOCs）的排放特征，选取九个重点行业及其代表性企业进行实地调研与测量。分析了不同行业排放的VOCs特征。基于测量数据，计算了所有监测企业的VOCs排放量，以获取本地化排放因子。结果表明，不同行业的VOCs成分存在一些差异，主要的VOCs成分是烷烃和卤代烃。乙烷、乙炔、氯甲烷（包括1,1 - 二氯乙烷、1,1,1 - 三氯乙烷）和氟利昂（氟利昂12或氟利昂114）是大多数行业的特征物种。结果表明，不同类型石化行业的主要VOCs排放环节为设备泄漏、装卸挥发、储存挥发损失和有组织排放，这些环节占排放量的40%以上。合成橡胶和钢铁制造行业计算出的VOCs本地化排放因子接近指南中的推荐值，而其他行业存在较大差距。
