焦炉烟道气脱硫脱硝工艺的选择

Selection of Desulfurization and Denitration Technology for Coke Oven Flue Gases

近些年来,国内大气环境逐渐恶化,雾霾围城,国家和地方相继出台环保政策应对污染天气的变化。焦炉煤气在燃烧过程中会产生SO2和NOx,这些SO2和NOx是PM2.5颗粒物的重要组成成份,也是形成酸雨、雾霾等的主要原因,必须采取措施加以控制。本文通过几种常用的烟气脱硫脱硝工艺的比较,选择出一种适合峰煤焦化公司的工艺路线。

Recently,the domestic atmospheric environment has worsened increasingly and the haze has been surrounding the city,therefore,the national and local departments have introduced the environmental protection policies successively to response to the change of air pollution.In the process of burning,the coke oven gas will produce SO2 and NOx,which is the important composition of PM 2.5 particulate matter and also the main reason for acid rain and haze,therefore,measures must be taken to control it.In this paper,through the comparison of several common-used fuel gas desulfurization and denitration technologies,it has selected out one technology suitable for Hebei Feng Coal and coking Co.,ltd.
