苯菲尔法脱碳液中DEA测定方法的改进

IMPROVEMENT ON DEA DETERMINATION METHOD IN BENFIELD CARBON REMOVAL SOLUTION

DEA是大型氨厂脱碳系统较常用的活化剂 ,而对DEA的几种测定方法较繁琐费时 ,改进后的测定方法简便易操作 ,准确度较高 ,相关系数为 0 9995 ,回收率为 95 6%～ 1 0 2 8% ,并具有良好的稳定性。

DEA is a kind of activator generally used in carbon removal system in large-scale ammonia plants,however,the original DEA determination methods are rather complicated and time wasting,while our improved method is more flexible and easy to operate,with high accuracy and stability.The relevant coefficient is 0.9995,the recovery rate is 95.6%～102.8%.
