This paper presents a case study of pinch analysis for xylene fractionation and CCR-Plateforming processes which are highly energy intensive. A combination of 4 hot and 3 cold streams was considered for process integration. An Aspen Energy Analyser simulation was performed for the considered data. A minimum temperature difference (ΔTmin) was considered to be as 10 ?C. Pinch temperature was found to be 103 ?C and hot utility usage was found to be reduced by 53.01 kW. The initial investment was found to be Rs 2.49*10^6 while profit generated was found to be 2.79*10^6 giving a payback period of 10 months.
