Optimization of factors inlfuencing the experiments on reactions involving 8 different chelating agents and sol-uble Fe (III)/Fe (II) salts was carried out to yield chelated iron complexes. A combination of optimized inlfuencing factors has resulted in a Fe chelating capacity of the iron-based desulfurization solution to be equal to 6.83—13.56 g/L at a redox potential of 0.185—0.3. The desulfurization performance of Fe (III)/Fe (II) chelating agents was investigated on a simulated sulfur-containing industrial gas composed of H2S and N2 in a cross-lfow rotating packed bed. Test results have revealed that the proposed iron-based desulfurization solution showed a sulfur removal efifciency of over 99%along with a Fe chelating capacity exceeding 1.35 g/L. This desulfurization technology which has practical application prospect is currently in the phase of commercial scale-up study.
