Case Study
Based on the application of our chelated iron catalyst in the alkaline desulfurization process, and a comparison of operating parameters with similar domestic catalysts, the following conclusions can be drawn:
Our chelated iron catalyst demonstrates superior stability with lower consumption rates compared to other suppliers.
It is understood that false foaming is a common issue with competing chelated iron catalysts from other manufacturers.
Our chelated iron catalyst provides better regeneration performance, resulting in lower soda ash consumption than other manufacturers.
| Parameter | other supplier | Our | Remark |
|---|---|---|---|
| H₂S Outlet Concentration (mg/Nm³) | 100-300 | 5-20 | |
| Triple Salt Content (g/L) | about 300 | about 210 | |
| Waste Liquid Discharge (m³/d) | 50 | 0 | |
| Sulfur Production (t/d) | about 2 | about 6 | |
| Desulfurization Tower Pressure Drop (kPa) | 5 | 1.5 | |
| Sulfur Foam Condition | false foam | thick sulfur foam | |
| Daily Catalyst Consumption Cost | CNY8800 | CNY7200 | |
| Daily Soda Ash Consumption Cost | CNY7800 | CNY5200 | |
| Waste Liquid Treatment Cost | CNY17500 | 0 | |
| Total Operating Cost | CNY34100 | CNY12400 | This cost calculation does not take into account the reduction in operating costs achieved by lowering the load on the flue gas desulfurization system as a result of the significant decrease in outlet H₂S concentration. |
