| Abstract: | A theory framework is presented for flexible heat exchanger network(HEN) synthesis considering the scheduling of cleaning maintenance at initial design stage.By means of simultaneous optimization of flexible HEN synthesis and cleaning schedule,the total annual cost of the heat exchanger network can be further reduced,and the network flexibility is improved at the same time.In order to reduce computational complexity for this problem classified as NP-hard problem,a two-stage approach involving preliminary sy... |
