摘要
介绍了电位法测定原油酸值主要的几种滴定模式,并比较了它们的特点及差别,提出了应用动态滴定模式测定原油酸值的方法。通过选取原油试样在不同滴定模式下测定酸值的对比实验,验证了采用动态电位滴定模式测定原油酸值的方法具有较高的准确度和精密度。
Several potentiometric titration methods for the determination of crude oil acid number were reviewed, and their characters and differences were compared. A method for the determination of crude oil acid number in a dynamic mode was established. The sample analysis experiments with different titration methods showed that the dynamic mode of the potentiometric titration to determine acid number of crude oil has high accuracy and precision.
