摘　　要：介绍了采用半干法脱除焦化厂焦炉烟气中的SO2污染物的工艺流程,以及该工艺不能实现稳定达标情况下,通过脱硫剂的变更以及向反应塔内喷入改为从废气烟道喷射脱硫剂的工艺改进技术使烟气的SO2达标排放。The paper introduces the technological process of removing SO2 pollutants from coke oven smoke of coking plant by semidry method,and under the condition that the process can’t reach the standard stably,through the change of desulfurizer and process improvement technology of transforming from injecting into the reaction tower to spraying desulfurizer from exhaust flue and finally make the emission of SO2 reach the standard.
