库仑滴定法与蒸馏法测定原油水含量的比较

Comparison of Determination of Water in Crude Oils with Coulometric Karl Fischer Titration Method and Distillation Method

与传统的蒸馏法相比,使用LC-4原油水含量测定仪和专用试剂,基于库仑滴定法测定原油的水含量快速准确,样品和试剂用量少,精度高,重复性好。

Compared with commonly used distillation method for determination of water in crude oils,based on the crude oils water content analyzer（type LC-4） and special reagent the coulometric Karl Fischer titration method is rapid,accurate,fairly precise,and can save sample and reagents,and shows good repeatability
