The complex iron desulfurization process is a wet oxidation method using complex iron as a catalyst to remove hydrogen sulfide. Its characteristic is to directly convert H2S in the gas into elemental S. After absorption, the H2S content in the gas is less than 20ppm. It is a new type of desulfurization technology with simple process, high working sulfur capacity, and environmentally friendly and non-toxic. The sulfur recovery rate reaches 99.9%, and the purified tail gas can meet the continuously improving environmental indicators. The complex iron desulfurization process is suitable for sulfur recovery units with H2S content of 0-100% and 0.1-20 t/d.
The optimal specification for a sled mounted complex iron sulfur recovery unit is a single set of sulfur less than 2 t/d.
