“四步法”资源化处理工业含硫废气的工艺研究

The Process Research on Four-Stage Treatment of Turning Industrial Sulfuric Flue Gas into Resources

针对某石化厂排放含硫废气的问题,采用资源化技术实现深度脱硫。通过分析含硫废气的组成和浓度,结合旋转RTO技术与克劳斯脱硫工艺,开发高效节能与绿色环保的含硫废气治理技术,使用Aspen Plus模拟软件建立分离该含硫废气的工艺流程,废气处理工艺采用四步法,结合Aspen Energy Analyzer、CUP-TOWER、SW6-2011等软件校核主要塔设备和反应器性能,研究结果表明:设计的塔器、反应器校核合格,项目的脱硫效率高达99.74%。

Sulfuric flue gas emission from some petrochemical plant isdeeply desulfurizedwith recycling technologies.By analyzing the composition and concentration of sulfuric flue gas,this paper proposes to develop highly energy-efficient and environment-friendly technologies of sulfuric flue gas treatment with RTO technology and Claus desulfurization process,establish a process flow to separate the sulfuric flue gas on Aspen Plus simulation software.This process adopts a four-stage method and checks the performance of the major towers and reactors on such soft wares as Aspen Energy Analyzer,CUP-TOWER and SW6-2011.The research results indicate that the towers and reactorsare designed reasonably with a 99.74%of sulfur removal efficiency.
