南京市印刷行业VOCs成分谱及臭氧生成潜势
|
摘要
通过对南京市印刷行业挥发性有机物(VOCs)进行采样监测,获得南京市印刷行业不同工艺VOCs源成分特征谱数据,并计算不同工艺VOCs排放的臭氧生成潜势,结果表明:该地区印刷行业VOCs排放源以醇类、烷烃、烯烃、卤代烃物质为主,VOCs贡献率达到83.6%。凹印、平印和凸印排放的VOCs均以含氧有机物和烷烃为主,三者含氧有机物质量百分比分别为36.01%,57.75%和50.95%,烷烃分别为30.16%,17.35%和20.71%。凹印排放VOCs的臭氧生成潜势最大,为1.91 g/g,平印排放VOCs的臭氧生成潜势为1.04 g/g,凸印排放VOCs的臭氧生成潜势为0.84 g/g。
Compositions of VOCs released from printing industryin Nanjing were measured to obtain the characteristic spectrum data of the VOCs in different processes.And the ozone formation potential(OFP)of the VOCs in different processes was calculated. The results showed that the emission sources of VOCs in printing industry werealcohols, alkenes and halogenated hydrocarbons, which contributed 83.6% of VOCs. The VOCs released from gravure,lithography and letterpress were OVOCs(oxygenated volatile organic compounds) and alkanes. The percentages of OVOCs released by those three printing methods were 36.01%, 57.75% and 50.95% respectively, and the alkanes were 30.16%, 17.35% and 20.71% respectively. The OFPs of gravure,lithography and letterpress were 1.91, 1.04 and 0.84 g/g, respectively.
