摘　　要：以某厂干熄焦高硫烟气治理为例,介绍了2种高硫烟气除尘及脱硫的超低排放环保工艺路线,一种是新建干熄焦高硫烟气处理系统,另一种是利用原焦炉烟气脱硫脱硝系统对高硫烟气处理,同时对这2种工艺进行技术对比和经济分析。An example is shown for treatment of high sulfur circulating gas from a CDQ system,in which two methods of high sulfur circulating gas dedusting and ultra-low discharge of the emission after DeSO_x are introduced,i.e.one is to build a new emission control system for the CDQ,another is to use the existing DeSO_x and DeNO_x system for the high sulfur circulating gas treatment.Technical and economical analysis is also made for the two methods.
