中国石化九江分公司采用新一代在线核磁共振(NMR)分析仪对原油及其馏分油的物性进行分析。通过对新一代在线NMR分析技术的了解和剖析,建立相应的数学模型,使NMR谱图与油品物性数据相关联,达到分析原油及其馏分油物性的目的。将NMR分析得到的数据与常规方法分析结果进行对比,发现数据再现性在分析方法误差允许范围内。
China Petrochemical Jiujiang Branch uses a new generation of on-line nuclear magnetic resonance (NMR) analyzer to analyze the properties of crude oil and its distillates. Through the understanding and analysis of the new generation of on-line NMR analysis technology, the corresponding mathematical model is established and the NMR spectrum is correlated with the oil physical property data to achieve the purpose of analyzing the physical properties of crude oil and its fractions. The data obtained by NMR analysis were compared with the results of conventional methods and it was found that the reproducibility of the data was within the allowable range of analytical method error.
