dc.description.abstractA B S T R A C T Hydrocarbon-Type composition analyses by Nuclear Magnetic Resonance (NMR) technique were carried out on some Nigerian Petroleum Produces - Heavy-Naphtha, Aviation Turbine Kerosine (ATX) and straight-run kerosine. The results were compared and correlated with corresponding results obtained from the PONA Analyser and FIA techniques (these results were obtained from the Nigerian National Petroleum Corporation Refinery, Kaduna) using a computer Regression subprogram. Analysis of the regression output showed that there is a good fit between the NMR and the FIA data for the ATK fractions, while the fit between the NMR and PONA analyser for Heavy-Naphtha were not as good. A number of prediction equations were given based on the regression output. The NMR technique compares favourably with the established methods and coupled with faster times of analysis, (an average of 30 to 40 minutes per sample compared to an average of 2 to 3 hours per sample for FIA technique), lower cost in terms of instrumentation and man-power. The NMR technique can be standardized and used for hydrocarbon-type composition analysis. With consideration being given to the construction of a completely automated NMR for performing these tests, the NMR technique is on its way to being an important supplemental technique for hydrocarbon - type analysis.en_US
