| 换热网络是过程工业中能量回收的重要系统，其设计水平的高低直接决定了过程系统的能耗和经济性。为了准确计算换热网络的[XC]损失，笔者
研究了换热网络优化设计中的流动[XC]损求解方法和碳排放量计算方法，将碳排放、流动[XC]损失和传热[XC]损失因素加入优化目标函
数，以此确定换热网络最佳的最小传热温差值，提出了考虑碳排放的换热网络[XC]经济学优化方法。将文中方法获得的结果与传统夹点分析法结果进行
比较，结果表明考虑碳排放的[XC]经济学优化方法是有效实用的，为低能耗、低碳排放的换热网络设计提供了参考。 |

| As an important energy recovery system of process industry, the heat exchanger network (HEN) design directly determines the level of energy
recovery and the economy of system. In order to calculate exergy loss of HEN（heat exchanger network） exactly, the calculation methods of flow exergy loss and carbon emissions were
studied in this paper. The carbon emissions, flow exergy loss and heat transfer exergy loss were involved in the optimization object function to determine the best minimum heat transfer
temperature difference of HEN. The exergoeconomic optimization method of HEN considering carbon emissions was presented. The results of the presented method and pinch analysis
method were discussed. Case studies demonstrate the effectiveness and application prospect of the presented method and provide a reference for the design of heat exchanger network with
low energy consumption and low carbon emission. |
