处理挥发性有机废气的几种典型吸附技术

来源于化工、医药、汽车领域的挥发性有机废气(Volatile Organic Compounds,VOC)是一种常见的空气污染物质,也是造成光化学烟雾的因素之一。近年来各国对VOC的排放政策都越来越严格。VOC的处理方法常见的有吸附法、热力燃烧法等,其中吸附法由于无二次污染、处理效率高而得以普遍应用。对于不同类型的VOC废气,采用吸附法处理时需要对吸附技术进行改进后再应用到实际,针对于此总结了处理不同类型VOC废气的吸附技术。

Volatile Organic Compounds（VOC ） is among a common air pollutants emitted from chemical, pharmaceuticalsindustry and vehicle field, besides, it＇s also a key factor that lead to photochemical smog. The governments of variouscountries also formulate strict regulations to restrict the emission of VOC. There are many methods to control VOC, suchas absorption, thermal oxidation. Between them the absorption method is widely used as its advantages of no secondarypollution and high removal efficiency over other techniques. However, as the different types of VOC, there need corre-sponding absorption method to control them. In view of that, the paper listed some different absorption techniques whichused in controlling different VOC.
