改良络合铁法脱硫的研究

Study of Desulfurization by Improved Complex Iron

本文介绍了一种新型的络合铁法脱硫新工艺,此吸收剂系碱性溶液中的络合Fe^(2+)/Fe^(3+)的变价体系.此络合体系为二元络合体系,以柠檬酸作为Fe的络合剂.研究表明,该新型脱硫剂具有脱硫效果好、硫容量高、副反应少、溶液成本低、腐蚀性小等优点,适宜于工业实际应用.

A new desulfurization process by improved complex iron was developed. The absorbent is a complex Fe^(2+) / Fe^(3+) system in basic solution. It is a dual complex system regarding citric acid as Fe complex agent. It is indicated that the new desulfurization process is high efficiency,high sulphur loading,low absorbent cost,low conosion and less side reaction. This process can be used for commercial run.
