ANALYSIS OF OZONE FORMATION POTENTIAL AND SECONDARY ORGANIC AEROSOL FORMATION POTENTIAL OF VOCs IN A COKING PLANT

  • 摘要: 焦化厂因其工艺特殊,SO2、NOx、颗粒物及VOCs的排放问题较为突出。故对焦化厂厂界环境空气VOCs排放特征进行分析,并依据最大增量反应活性(MIR)法和等效丙烯浓度(PEC)法对VOCs的臭氧生成潜势(OFP)进行评估,依据气溶胶生成系数(FAC)法对VOCs二次有机气溶胶生成潜势(SOAFP)进行评估。结果表明:1)厂界上、下风向5个点位共分析出包括芳香烃、卤代烃、烯烃、硫化物、酮类在内的17种VOCs; 2)不同区域厂界检出的VOCs差异显著,总质量浓度为28.2~167.9μg/m3,其中芳香烃在各点位TVOCs中占比最大,达到51.01%~84.63%;3)脱硫提盐冷鼓区域边界OFP最大,理论值为335.51μg/m3,办公生活区边界OFP最小,理论值为47.06μg/m3,芳香烃对OFP贡献率为27.21%~62.37%,烯烃为39.17%~61.84%,卤代烃为2.08%~14.56%;通过PEC法估算OFP,结果变化趋势与MIR法结果相一致,等效丙烯浓度为3.11~31.89μg/m3;且1—5点位芳香烃的等效丙烯浓度贡献率分别为37.10%、51.46%、66.79%、58.80%和22.74%;4)1—5点位SOAFP分别为0.452,0.938,2.517,4.055,0.495μg/m3;芳香烃对SOAFP贡献最大。丙烯、甲苯、二甲苯、氯乙烯等质量浓度和反应活性均较大的物质,是需要优先控制的VOCs组分,可作为焦化厂环境空气VOCs的标志物。
