    多周期换热网络柔性综合与维护同步优化

    • 摘要: 提出柔性换热网络在初始设计阶段,考虑网络投入运行后,实施清洗维护时序安排的理论框架。通过柔性综合与维护同步优化,年度总费用能够进一步降低,同时网络柔性得到提高。为降低该NP难问题的计算复杂性,提出柔性换热网络初步综合和同步优化相结合的两阶段法。最后,通过计算实例验证了所提方法的有效性。

       

      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 synthesis stage and simultaneous optimization stage is introduced. In the last section, the efficiency of the proposed approach in this paper is validated by a numerical example.
