ASSIGNMENT (Heat Exchanger Network) Question 1 a) For Tmin=10C, find the minimum utility requirements for a network of heat exchangers involving the following streams: b) Repeat (a) for the following streams: (c) For (a) and (b), design HENs that require the minimum utilities. Figure 1. Existing palm oil mill block diagram. Table 1. Extracted heat data. igure 1 shows a palm oil mill block diagram and Table 2 shows the extracted heat data. Figure 1 shows a palm oil mill block diagram and Table 2 shows the extracted heat data. a) Apply Composite Curves or Problem Table Algorithm to obtain a minimum heating and cooling utility target of 130MW and 220MW respectively with a hot and cold pinch temperature of 180C and 170C respectively. Assume Tmin of 10C for the streams extracted in Table 1. b) Calculate the percentage of cooling and heating reductions and compare to no heat integration c) Draw a grid diagram to show how the streams can be integrated in order to achieve the minimum heating and cooling requirements in part (a). Label each heat exchangers heat duty. d) Redraw the palm oil mill block diagram with the new heat exchanger network
