ENERGY INTEGRATION OF HYDRODESULPHURIZATION PLANT USING PINCH ANALYSIS (A CASE STUDY OF KADUNA REFINING AND PETROCHEMICAL COMPANY HDS PLANT)

Abstract

Energy management is a critical activity in the developing as well as developed countries owing to constraint in the availability of primary energy resources and the increasing demand for energy from the industrial non industrial users. Energy consumption is a vital parameter that determines the economic growth of any country. Pinch technology is a vital tool to achieve this objective. Therefore energy Integration of Hydrodesulphorization Unit of Kaduna Refining and Petrochemicals Company was carried out using Pinch Technology. Optimum minimum approach temperature of 200e was obtained. The pinch point was round to be 523 K and the hot and cold pinch temperatures were found to be 247 and 231 °e respectively. The utilities targets for the minimum approach temperature were found to be 2,420.5 I kW and 3366.86 kW for hot and cold utilities respectively. The utility and capital cost for optimum MTA of 100e are $1.5 x 106 and $0.22 x I(/' respectively. The cold util ity requirements of traditional energy approach and pinch analysis ol'HDS obtained arc 15,144.62 kW and 3366.86 kW respectively while the hot utility requirements of traditional energy approach and pinch analysis are 15,332.667 kW and 2,420.51 k W respectively. Pinch analysis as an energy integration technique saves more energy and utilities cost than the traditional energy technique
