RESUMO

In this work a computational program was developed interfacing heat exchanger network synthesis and detailed heat exchanger design. The program uses the concepts of Pinch Technology. To the network synthesis are defined initially the targets with respect to the global minimumcost, optimum ATmin, minimum exchange area, minimum number of units and the hot and cold utilities demand. The network is synthesized using the Pinch Design Method. After these, the network is evolved, identifying and breaking loops without changes in the utilities demand. After the evolution, the exchangers are designed considering pressure drop and fouling, using the Bell-Delaware method. The program was developed in modular form, and the utilization of each module is explained using literature problems. An industrial problem is used to show the applicability of the program developed. The results shown the consistency in the methodology reflecting the importance of the termohidraulic design in the heat exchanger network synthesis
