摘　　要：分析了将焦炉煤气常用的PDS脱硫工艺直接改用络合铁催化剂脱硫工艺进行脱硫存在的问题。针对存在的问题,对设备、工艺及操作进行了一系列的改进和优化。经改进和优化,系统指标达标的同时,还保证了系统的长期、连续、稳定运行。从根本上避免了脱硫系统堵塞及脱硫废液增加的问题,对整个焦化行业焦炉煤气脱硫具有引领和示范作用。In this paper, existing problems have been analyzed for the commonly-used PDS process for COG desulfurization directly changed to complex iron catalyst desulfurization.Improvement and optimization have been done in aspects of equipment, process and operation.This attempt not only obtains the required performance, but also ensure uninterrupted and stable operation of the system in the long-run. Fundamentally, it avoids clogging in the desulfurization system and the increasing of waste desulphurization liquid so that the bottleneck can be tackled,which spearheads the whole coking industry in COG desulfurization.
