摘要
采用三级膨胀法,按照ASTM D6378-08标准[1]测定了石油产品、烃类及烃类-含氧化合物混合物的蒸汽压力,并在此基础上对蒸汽压力检测的不确定度进行了评估。探讨了重复性操作、温度传感器和压力传感器对不确定度的影响。
Vapor pressure of petroleum products,hydrocarbons,and hydrocarbon-oxygenate mixtures was determined by using triple expansion method according to ASTM D6378-08.The method uncertainty was evaluated.Many factors which may influence the result of uncertainty were discussed,such as repeatability,temperature sensor and pressure sensor.
