Abstract
Abstract In this work, different refinery configurations are investigated for upgrading projects to increase gasoline production for local market demand. Different alternatives for the upgrading can be tackled. Either direct upgrading of the atmospheric residue, or first subject the atmospheric residue to vacuum distillation then upgrade the vacuum residue and vacuum gas oil to more valuable and lighter products. Obtained results show that, the scenario which included fluidized catalytic cracking (FCC) has shown the optimum in terms of both maximum gasoline and less capital cost compared with configuration that included the delayed coking process
