Characterization of CRUDE OILS and petroleum products: (i) elution liquid chromatographic separation and gas chromatographic analysis of crude oils and petroleum products

E.O. Odebunmi, E.A. Ogunsakin, P.E.P. Ilukhor


Some physical and chemical properties of samples of light, medium and heavy Nigerian crude oils and petroleum products including gasoline, kerosene and engine oil have been measured and are reported in this paper. The crude oils and petroleum products have also been characterized by fractional distillation and elution liquid chromatography. The fractions obtained from elution liquid chromatography were analyzed using gas chromatography (GC). The GC fractions were identified by comparing the retention time of peaks in the unknown samples with those of components of calibration standard mixtures. The importance of the physico-chemical properties and the significance of the fractional distillation and chromatographic separation methods to industrial process operations have been discussed.
