Abstract:

This study presented a new method to accurate design of shell and tube heat exchanger network. It’s considered some parameters as decision variables such as the design of determined the flow path of each fluids, number of required shell side, allowable velocity and pressure drop, number of tubes, number of passes in shell and tube sides, length of tube, layouts of tubes, size and percentage of baffle cut, shell diameter, tube diameter, tube pitch and experimental equations to calculate pressure drop and heat transfer coefficients in shell and tube side heat exchanger units. It has been used whale algorithm to achieve optimum total annual cost for heat exchanger unit. The total annual cost is as objective function that included capital and energy costs. The results showed in two cases studies including four and ten streams in shell and tube heat exchanger networks. The total annual cost reduced almost 20.55% and 14.40% compared with others for two case study.
