VOCs废气物理处理工艺研究进展

Research Progress on VOCs Physical Ttreatment Technology

近年来我国化工行业的快速发展使得挥发性有机物(VOCs)的排放逐渐增加,对环境保护和人类健康都造成了巨大的影响。VOCs的种类多,难以像氮、硫氧化物一样进行有针对性的治理。本文针对常见VOCs物理处理技术的优缺点进行了讨论,并对典型的吸附法流程进行了介绍分析。在目前VOCs的物理治理方法中,吸附法以其投资低、工艺简单、效率高等优点,应用最为广泛。

VOCs gas is very impact to the environment and humans.It is difficult to carry out targeted treatment like nitrogen and sulfur oxides because of the huge mount of VOCs types.The article describes the advantages and disadvantages of common VOCs physical treatment technology,and introduces and analyzes the typical VOCs treatment process by adsorption.Among the current physical treatment methods for VOCs,the adsorption method is the most widely used due to its advantages of low investment,simple process,and high efficiency.
