焦炉推焦烟气脱硫工艺的选择与实践

Selection and practice of desulfurization process for pushing emissions control

阐述了焦炉推焦烟气中二氧化硫的排放特点,提出以NaHCO_(3)作为脱硫剂的干法推焦烟气脱硫工艺,实践证明,该工艺简单,灵活性高,脱硫效果良好,应用范围广,具有借鉴意义。

The paper describes the emission features of SO_(2) in pushing emissions,and proposes the dry desulfurization process,which uses NaHCO_(3) as the desulfurizer agent.The practice demonstrates that this process is characterized with simple operation,high flexibility,good desulfurization performance and wide range of application,which can be used as reference in the coking industry.
