摘　　要：焦炉煤气脱硫系统胺液变质导致脱硫能力下降和单乙醇胺消耗升高,通过分析确定了胺液中热稳定性盐的物理特性及其各主要组分的含量。通过滤芯-活性炭-阴离子交换树脂的动态胺液净化工艺可以使胺液中的热稳定性盐含量维持在1%左右。To solve the problems of desulfurization capacity reduction caused by monoethanolamine(ME A)deterioration in the COG desulfurization system,and the increased consumption of MEA due to thermally stable salts generated in the process,physical properties of the amine liquid and its major composition are determined through physical and chemical analysis of desulfurization of amine liquid.The thermally stable salt content of amine solution in desulfurization system can be maintained around 1%by the dynamic amine solution purification process of filter element-activated carbonanion exchange resin.
