炼化VOCs废气安全高效热氧化技术研究

Study on safe and efficient thermal oxidation technology of VOCs from refining and chemical industry

VOCs即挥发性有机废气,其广泛存在于炼化生产工艺流程当中,VOCs废气进入大气后会发生光合反应,进而产生臭氧及PM2.5,造成严重的空气污染。化工行业积极进行生产技术革新,以满足不断提高的环保指标要求。本文介绍VOCs废气的来源、危害、属性以及两种化工企业常用的安全高效热氧化技术,并结合具体案例,分析热氧化技术在VOCs废气中的应用,为相关研究的开展提供理论参考。

VOCs are volatile organic waste gas,which widely exists in refining and chemical production process.After entering the atmosphere,VOCs waste gas will produce photosynthesis reaction,and then produce ozone and PM2.5,causing serious air pollution.Chemical industry is actively carrying out production technology innovation to meet the requirements of environmental protection index.This paper introduces the sources,hazards and properties of VOCs waste gas,as well as two kinds of safe and efficient thermal oxidation technologies commonly used in chemical enterprises.Combined with specific cases,the application of thermal oxidation technology in VOCs waste gas is analyzed,which provides theoretical reference for related research.
