Abstract
Light gas oil (LGO) and long residue (LRS) fractions used to prepare the LPFO blends were collected from two Nigerian refineries and similar products were obtained from Venezuela (foreign crudes). The physicochemical properties of the blends were determined using the American Society for Testing and Materials (ASTM) methods and other analytical techniques.Comparison of the results with the ASTM standard values indicates that the Nigerian blends are of higher quality than the foreign blends. For instance, the mean value of vanadium was 400% higher in the foreign blend and the Nigerian crude has low sulfur levels. Thus, the regulatory agencies in Nigeria should enforce the specification laws to ensure that crudes imported do not impact negative effects on the industry and around the globe.
