摘要
焦化脱硫溶剂再生装置胺液中热稳态盐超标使脱硫效果变差、通过装置运行情况分析发现,胺液质量提升,可以有效避免液化气在脱硫过程中发生副反应形成硫醚及二硫化物,降低胺液发泡性能,从而可以长期稳定提高液化气的脱硫效果,大幅降低焦化液化气的总硫含量.
Abstract
The high-temperature steady-state salt in the amine solution of the coking desulfurization solvent regeneration unit makes the desulfurization effect worse.Through the analysis of the operation of the unit,it is found that the improvement of the quality of the amine solution can effectively prevent the formation of sulfur ether and disulfide from side reactions during the desulfurization process of the liquefied gas,reduce the foaming performance of the amine solution,and thus improve the desulfurization effect of the liquefied gas stably for a long time and greatly reduce the total sulfur content of the coking liquefied gas.
