Abstract—The energy and exergy analysis of FCCU of Kaduna Refining and Petrochemical Company (KRPC) Nigeria is presented. The primary objectives of this work were to analyze the system components separately and to identify and quantify the sites having largest energy and exergy losses. The performance of the plant was estimated by a component wise simulation using Aspen Hysys software and a detailed break-up of energy and exergy losses for the considered plant has been presented. The ideal work was calculated to be (- 74.169 MW) which characterized the system as work producing. Energy losses mainly occurred in the fractionator column where 46.6MW is lost to the environment while only 3.69, 1.77 and 0.68 MW was lost from the condensers, other equipment and absorbers respectively. The percentage exergy and second law efficiencies of the system was found to be 61.20 and 24.77 %.
