络合铁法脱硫工艺研究进展

Research Progress on Desulfurizing Process with Chelated Iron

综述了国内外络合铁法脱硫工艺的现状和发展趋势,重点介绍了脱硫液的氧化再生、硫磺颗粒的改性、络合剂的降解、抑制副产物生成等方面的研究进展,并简评了络合铁法脱硫工艺的特点及应用。

This paper reviewed status and developing trends of chelated iron process for removing H2S both inside and outside China. The following developments were emphasized： oxidation and regeneration of desulfurizing solution, modification of sulfur granule, degradation of chelating agent and inhibiting by-product generation. The applications and features of desulfurizing process with chelated iron were also briefly evaluated.
