The purpose of this paper is to investigate the energy consumption in H2O2 pilot plant can be saved. For this reason, the H2O2 pilot plant in Arak center of Petrochemical Research & Technology Company (NPC-RT) has been considered for investigation. First, by studying process flow diagram, the hot and cold streams and their inlet and outlet temperatures are identified. Then by using pinch technology was estimated and the heat exchanger network was designed. It was specified that the heat exchanger network has 6 process heat exchangers which by adding them in HEN, the hot and cold utility consumptions decreased about 15% and 12% respectively. By increasing the capacity up to 10,0000 tones per year the amount of pay back period decreases up to 1.7 year.
