Determination of Components and Properties in Petroleum by Nuclear Magnetic Resonance Spectroscopy
Nuclear magnetic resonance is a physical phenomenon based on atomic nuclei used to study the structure and properties of substances.Currently,a large number of nuclear magnetic resonance analysis methods are applied in the analysis and research of medical,chemical industry,and other fields.Based on the analysis of the distillation range of atmospheric first-line fraction in petrochemical product distillation units,a rapid analysis that can be applied to products has been determined through analysis modeling and human-machine comparison.At the same time,to further expand the scope of its analytical applications,the analysis projects will be expanded to study the density and full distillation range of light oils such as distillation,coking,diesel hydrogenation,hydrocracking,and coking kerosene hydrogenation.The experimental equipment mainly relies on the DF-NMR-I offline nuclear magnetic resonance analyzer,which selects distillate crude oil and diesel oil from the refinery.The relevant measurement parameters refer to national standard methods.By using the principle of nuclear magnetic resonance and collecting hydrogen spectra of oil products,clustering analysis of oil products can be performed effectively;With the support of a large amount of data,the function of quickly predicting the properties of oil products can be achieved through modeling techniques.Realizing the efficiency,high precision,and real-time performance of analysis work will have a profound impact on the analysis of oil products in the chemical industry.
