Advantages of the complexed iron hydrogen sulfide removal process
Thread Content
SO2 emission levels meet the standards: < 50 mg/Nm3. The process requires low investment, occupies little space, has low operating costs, ensures stable device operation, and does not generate any secondary pollutants. The increasingly stringent environmental regulations are forcing companies to adopt new technologies for the removal of hydrogen sulfide gas; the complex iron process can effectively remove hydrogen sulfide gas, helping companies meet environmental standards while maximizing their profitability.
Please introduce the complexed iron desulfurization process

Our company’s Luohe Tie technology: 1. Operating cost: 800–1,000 yuan per ton of sulfur; for a project with a sulfur production capacity of 6 tons per day, the investment required is 15–20 million yuan. 2. Reaction temperature: 50°. 3. The solution pH is 8-9. 4. Chelating agents need to be replenished regularly. 5. No emissions of waste gases, wastewater, or solid waste. 6. Hydrogen sulfide in the exhaust gas after desulfurization cannot be detected; if there are no other harmful gases, it can be discharged directly. 7. It can be fed into the sulfur melting device, enabling the production of sulfur that meets quality standards or is of first-class quality and can be sold directly
Chelated iron desulfurization — is it the use of chelating agents with a pH of 8-9 to absorb hydrogen sulfide? Chelating agents need to be replenished regularly, and since there are no emissions of waste substances, where does the chelating agent that is used go?
The pH value is maintained at around 8 using an alkaline solution, thereby improving the desulfurization effect of complexed iron. Theoretically, the entire process is a cyclic absorption and regeneration system that requires no consumption of chelating agents; however, in actual operation, there is slight loss due to sulfur melting at the end stage.
Okay~ Which region are you from as a manufacturer? Could you introduce yourself?
Shijiazhuang Precision Chemical Technology Co., Ltd. specializes in the development of continuous sulfur melting reactors.
