摘要
通过分析电量法测定原油盐含量的操作过程,对原油盐含量测定结果的不确定度进行了评定。不确定度主要来源于仪器测量重复性、进样体积、称样质量及样品密度。通过分析和量化各不确定度分量,确定仪器测量重复性所占比重最大。
The uncertainty in determination of salt content in crude oil by electricity quantity method was evaluated by analyzing the operation process. The results showed that the uncertainty mainly came from measuring repeatability,sampling volume, weighing quality and sample density. By analyzing and quantifying the uncertainty components, it's pointed out that the repeatability of the instrument had the largest proportion.
