| 摘 要： | 基于280余种典型的原油，采用衰减全反射测量方式结合偏最小二乘（PLS）方法建立红外光谱测定原油密度的校正模型。校正结果显示，交互验证标准偏差为0.005 1 g/cm3，预测标准偏差为0.004 4 g/cm3，均接近于标准方法的误差要求。与U形振动管法相比，该方法具有测量速度快速、操作简便等优点，其结果满足快速分析和过程控制分析的需要，在一定场合可以替代U形振动管法用于原油密度的快速预测。

| Abstract: | The combined use of mid-infrared attenuated total reflection spectroscopy and multivariate calibration to determine the density of crude oil was carried out.Calibration models for crude oil density were established by partial least squares(PLS) based on 280 crude oil samples collected worldwide.Results show that the standard deviation of cross-verification is 0.005 1 g/cm3 and the predicted standard deviation is 0.004 4 g/cm3,which are all close to the requirements of standard method,indicating that the res... |
