微量法检测石油产品饱和蒸气压的研究

Advantages of Micro Method in Determining Saturated Vapor Pressure of Petroleum Products

比较详细地介绍了微量法的测量原理和微量法检测石油产品饱和蒸气压实验的方法,并与传统的雷德法进行了准确性、重复性、再现性的比较。结果表明:微量法的准确性、重复性、再现性更好,而且微量法检测实验所用样品用量少,检测时间短,避免了雷德法检测时的人为操作误差,可以满足成品油质检室的日常分析要求。

The measurement principle of micro method and the method of testing saturated vapor pressure of petroleum products by micro method are introduced in detail,and the accuracy,repeatability and reproducibility are compared with the traditional Reid method.The results show that the accuracy,repeatability and reproducibility of the micro method are better,and the amount of samples used in the micro method detection experiment is less,and the detection time is shorter,which can avoid the artificial operation error of the Reid method detection,and the micro method can meet the daily analysis requirements of the finished oil quality inspection.
