焦炉烟气脱硫脱硝工艺研究

Study on Desulfurization and Denitration Process for Coke Oven Flue Gas

我国焦炭产能居世界首位,但炼焦过程中产生大量污染物。结合焦炉烟气的特点,并对典型的焦炉烟气脱硫脱硝工艺进行了分析,提出了一种半干法脱硫+除尘+活性碳纤维脱硝的新工艺,详细阐述了该工艺的工艺流程及脱硫脱硝反应原理。

The coke production capacity in China ranks the primacy in the world，but the coking process produces a great lot of pollutants．In combination with the characteristics of flue gas of coke oven，the paper analyzes the typical coke oven flue gas desulfurization and denitration process．Then．The paper introduces a new process of semi-dry desuIfurizatiOn+dust removal+activated carbon fiber denitration and describes the process flow and reaction principle of the process in detail．
