The first step is to<br /> employ heat integration in sequence and reduce the heat consumption and total<br /> annual cost of the process. The second one is to increase the exergetic<br /> efficiency of sequence by generating power in implemented expanders in<br /> sequence. The profit of power generation directly affects the operating cost of<br /> the process and decreases the total annual cost. In each step, the target is to<br /> minimize the objective function of total annual cost. A simulator is used to<br /> simulate the equipmentâs specification and formulate the objective function of<br /> cost. Results from employing these two integration steps for the considered<br /> case study show the advantages of such a complex distillation sequence with<br /> heat integration and power generation. The results represent a very high<br /> improvement for the sequence Indirect since the properties of the intake flow<br /> to the process are in a way that in this sequence not only do we have a high<br /> freedom for carrying out heat integration, but a large amount of power is also<br /> produced between the columns due to having high flow rate flows between the<br /> columnshttp://gpj.ui.ac.ir/article_20163_6587325a8883837189d6101ef0033303.pdf
