Abstract:

This study proposed the revampment of the four major refineries and the operation of conventional modular refineries in the localities for efficient and adequate availability of petroleum products. Hence, the research focused on the suitability and operations ofthe conventionalmodular refinery process by considering twenty (20) different types of Nigerian crude oil for crude oil assay analysis and classification using Aspen Hysys. The crude oil assay analysis results categorized the twenty Nigerian crude oil types as Sweet crude (sulphur content below 0.5wt%), Light crude oil (API value above 38), and Medium crude oil type (API value between 22 and 28). Also, the Nigerian crude oil types were grouped based on their percentage recovery volume at a true boiling point of 3700C as Group A (crude oil with recovery volume above 80% and residual percentage less than 20%), which is suitable for modular refinery operations in Nigeria. In comparison, Group B (crude oil with recovery volume between 70% and 79% and residual percent of over 20%) and Group C (crude oil with recovery volume below 70% and residual percentage value above 30%) are proposed for modified modular refinery process due to its high residual percent (above 20%) or are transported via pipelines or tankers to the major conventional refinery for the further operational process.
