工业VOCs排放源废气排放特征调查与分析

在大量调研工业挥发性有机物(VOCs)排放源案例的基础上,将工业VOCs排放源分为溶剂产品使用源、化工产品生产源、废物处理源和存储输送源4类,并对不同类型工业VOCs源的废气排放特征进行了分析.结果表明,大多数有组织排放的工业VOCs源的废气流量>1000m3/h,总挥发性有机物(TVOC)浓度100000m3/h的VOCs源以溶剂产品使用源为主;流量10000mg/m3或<100mg/m3的工业VOCs源,均以化工产品生产源为主.在工业VOCs源排放的各种VOCs组分中,以苯系物最为常见

Investigation of industrial VOCs emission sources and analysis for their emitting characteristics

After 433 industrial VOCs emission cases were searched and collected, these sources were classified into four types, which were solvent usage, chemical product manufacture waste treatment and storage and transportation leakage source. The emitting characteristics of different types of sources were analyzed. The results showed that most of on-pot industrial VOCs emission sources had similar emitting characteristic, such as having a flowrate more than 1000 m3/h, the concentration of total (TVOC) less than 10000 mg/m3 and complex chemical composition. Among all the investigated VOCs sources, most of the solvent usage sources had an emission flowrate higher than 100000 mg/m3. Most of the chemical product manufacture sources had a flowrate lower than 1000 mg/m3. The TVOC concentrations of most chemical product manufacture sources were higher than 10000mg/m3 or lower than 100 mg/m3. The most frequently found components in the industrial VOCs emission sources were BTEX.
