摘　　要：络合铁催化氧化硫磺回收工艺是一种适用于处理低含量硫化氢的气体净化技术,被广泛应用于天然气、沼气、油田伴生气等含硫化氢气体的净化回收工艺,硫化氢脱除率可达99.99%。从多角度对比了双塔脱硫和单塔脱硫两种常用的络合铁催化氧化硫磺回收工艺,对处理低含量硫化氢气体的工艺选择有一定的借鉴意义。Catalytic oxidation of complex iron desulfurization process is a gas purification technology suitable for treating low concentration hydrogen sulfide.It is widely used in the purification and recovery process of hydrogen sulfide containing gas such as natural gas,biogas,oilfield associated gas,and the removal rate of hydrogen sulfide can reach 99.99%.In this paper,two common catalytic oxidation of complex iron sulfur recovery processes,double-column desulfurization and single-column desulfurization,are compared from multiple perspectives,which can be used for reference in the process selection of low concentration hydrogen sulfide gas treatment.
