摘要

为了实现新型煤化工硫近零排放,介绍了活性焦燃煤烟气净化与煤气脱硫技术的原理、工艺流程及特点,结合2种工艺特点,以活性焦烟气净化再生产生的富SO_2气体和煤气脱硫产生的H_2S可反应生成硫磺为工艺技术切入点,提出了一种活性焦烟气净化与煤气硫回收技术有机集成的硫近零排放联合工艺,并进行了硫的物料平衡分析。结果表明,60万t/a煤制烯烃项目采用该联合工艺后,可建立起企业内部硫回收利用的循环经济产业链,煤炭中总的硫资源回收率达到85.69%,新增硫磺产能50%,回收硫磺总量为9 254 t/a,可节水60万t/a,且采用活性焦干法烟气净化技术可将燃煤烟气中SO_2与NO_x等污染物同时脱除,实现了较好的经济与环保效益。
In order to achieve near-zero emissions sulfur in new coal chemical projects,the principle,process and characteristic of coalburning gas purification technology with activated coke and coal gas desulfurization were introduced.SO_2 could react with H_2S to form sulfur,so a combined process of activated coke flue gas purification and gas sulfur recovery technology was proposed.Sulfur material balance of process was calculated.The results showed that circular economy industry chain of sulfur recovery and utilization was established in 6×10~5t/a coal-to-olefin project.Sulfur recovery rate,new sulfur capacity,total sulfur and water saving was 85.69%,50%,9 254 t/a and 6×10~5t/a respectively.Dry flue gas purification technology with activated coke could be used to remove SO_2 and NO_x in coal fired flue gas,which had better economic and environmental benefits.
