Kero hydrotreating unit being an integral part of the refinery system has been characterized by heat leaks, heat losses and inefficiencies in the heat transfer processes. This has necessitated the investigation into analysis of the current energy configuration to curb this menace and to proffer solution which would lead to efficient utilization of energy. Application of Pinch technology to kero hydrotreating unit heat exchanger network is presented with an optimum minimum approach temperature of 2.5°C to determine the energy target. This was achieved via the development of composite and grand composite curves for the kero hydrotreating unit process. The Pinch point temperature was found to be 544°C, with the utility targets for the minimum approach temperature being 7491.9 kW and 8259.62 kW for hot and cold utilities respectively, leading to energy savings of 34.33% and 32.17%..
