Victoria TIMOTHY, Usman Aliyu EL-NAFATY, Saidat Olanipekun GIWA


Abstract: Energy integration of Atmospheric distillation unit (ADU) and Fluid catalytic cracking unit (FCCU) of Kaduna Refinery and Petrochemicals Company was carried out using pinch analysis with the aid of HENSAD. In order to achieve the aim of the study, cold and hot streams data of the two units in question were extracted from the plants flow sheet and entered in to the spread sheet of the software appropriately and the following results were obtained; For the atmospheric distillation unit, the minimum temperature difference (Tmin) of 30oC was used and pinch point temperatures were 99oC and 69oC for hot and cold utilities respectively. Also, existing energy was 25324kW, the target was 18754kW and the energy saved was 31 % (6570kW) for the hot utilities; existing energy was 31733kW, the target was 21722 kW and the energy saved was 26 % (10, 011kW) for the cold utilities, with a total amount of $9, 582, 436.25 that could be saved annually. For the fluid catalytic cracking unit, the minimum temperature difference (Tmin) of 25oC was used and pinch point temperatures were 110oC and 85oC for hot and cold utilities respectively. Also, existing energy was 308952.7kW, the target was 243978kW and the energy saved was 21 % (64974.7kW) for the hot utilities; existing energy was 310340.4kW, the target was 242590 kW and the energy saved was 21.8 % (67750.4kW) for the cold utilities, with a total amount of $76, 704, 047.4 that could be saved annually.
