Coke oven flue gas desulfurization and denitrification technology progress and suggestions
焦炉烟气脱硫脱硝技术进展与建议

摘要

随着我国社会经济的发展与进步，人民群众的生活品质日益提高，人们对环保生态问题日益关注，国家环保部门对焦炉烟气脱硫脱硝工艺技术的要求越来越高。在焦化厂焦炉烟气脱硫脱硝过程中会向大气排放含有氮氧化物和二氧化硫等污染物的烟气，不仅会对环境造成影响，而且会产生酸雨，对大气造成严重的污染。目前，焦化焦炉烟气脱硫脱硝技术已有了较大的改进，对焦化企业的烟气污染治理具有一定的借鉴意义。基于此，本文综述了焦炉烟气脱硫技术的发展现状，对焦化行业选择脱硫脱硝工艺提出了相关建议。

Abstract

With the development and progress of China's social economy, the people's quality of life is increasingly improved, people are increasingly concerned about environmental and ecological issues, and the relevant departments have higher and higher requirements for coke oven flue gas desulfurization and denitrification process technology. In the process of coke oven flue gas desulfurization and denitrification in coke plants, flue gas containing pollutants such as nitrogen oxides and sulfur dioxide will be emitted to the atmosphere, which will not only affect the environment, but also produce acid rain and cause serious pollution to the atmosphere. At present, the coke oven flue gas desulfurization and denitrification technology has been greatly improved, which has certain significance for the flue gas pollution management of coking enterprises. Based on this, this paper reviews the development status of coke oven flue gas desulfurization technology and puts forward relevant suggestions for the selection of desulfurization and denitrification process in coking industry.
