Hydrogen sulfide (H₂S) and other sulfur compounds in the gas stream can cause equipment corrosion, catalyst poisoning, and sulfur contamination. The main component of the desulfurization agent is ferric oxide (Fe₂O₃), which offers excellent desulfurization efficiency, stability, and regenerability.

Main Uses:

Removal of hydrogen sulfide (H₂S) from gas streams to prevent equipment corrosion and environmental pollution

Protection of downstream equipment and catalysts in subsequent processes, thereby extending their service life

Reduction of sulfur emissions to comply with environmental regulations

Applications:

Desulfurization treatment of natural gas, shale gas, and coalbed methane in oil and gas fields

Gas purification in petroleum refining processes, such as FCC off-gas and tail gas from hydrotreating units

Desulfurization of coal gas and coke oven gas in coal chemical industry

Pretreatment of chemical feed gases such as synthesis gas for ammonia and methanol production

Purification of renewable energy gases such as biogas and landfill gas

Iron oxide desulfurizers are typically used under ambient or moderate temperature conditions, though products suitable for high-temperature applications are also available. They are characterized by high sulfur capacity, low operating cost, and regenerability.
