Our iron-based desulfurization media is engineered for reliable and cost-effective H₂S removal in upstream and midstream gas processing applications. It serves as the primary stage for bulk sulfur removal, protecting downstream systems and enabling efficient deep polishing.

Application Scenarios

Best suited for high H₂S gas streams and bulk removal stages prior to ZnO polishing.

• Natural gas, shale gas, coke oven gas (COG), and biogas
• High sulfur load conditions requiring bulk removal
• Systems requiring stable long-term operation
• Applications targeting optimized operating cost

Process Position

Iron-based media is used as the primary bulk removal stage in the H₂S removal process.

Key Benefits

• High sulfur capacity:20–45 wt% under typical operating conditions
• Stable performance:consistent removal efficiency across varying gas conditions
• Cost-effective operation:reduced media replacement frequency
• System protection:extends the life of downstream ZnO and catalysts
• Flexible application:suitable for a wide range of gas compositions and pressures
