| 摘 要： | 换热网络的夹点法设计是针对某一特定的工艺条件而进行的,投入运行以后,当流量或温度波动时,换热网络的操作夹点就不同于优化设计值,最小温差也不再是设计时根据设备费用和操作费用优化得到的最小温差.利用空间离散化的动态模型,对某炼油厂常减压蒸馏装置的换热网络进行操作分析,并提出了操作夹点优化控制设计方案,对换热网络进行动态优化... |

| Abstract: | The pinch point design of heat exchanger networks is performed based upon specific process conditions.During operation when the flow or temperature fluctuates,operation pinch point of heat exchanger networks is not the optimization design value any more,and the minimum temperature difference is no longer the minimum temperature difference after optimization of equipment costs and operating costs in design. Hereby,a dynamic model based on spatial discretization is adopted for the operation analysis of the CD... |
