The chelated iron desulfurization technology is a wet oxidation method for removing H2s that uses chelated ironas a catalyst. its main feature is the direct conversion of H2s into elemental Sulfur, with the treated H2s contentmeeting environmental protection requirements. This is a simple process with high sulfur capacity and is anenvironmentally friendly, non-toxic new desulfurization technology that overcomes the disadvantages oftraditional desulfurization processes, such as low sulfur capacity, complex processes, high by-product saltgeneration rates, and serious environmental pollution. The tail gas from the sulfur recovery unit can achieve asulfur recovery rate of 99.9%. 0ur company owns proprietary intellectual property rights to this desulfurizationtechnology, which is characterized by high sulfur capacity, low desulfurization costs, energy savings, highoperational stability, and low investment requirements compared to other desulfurization technologies.
