摘要

提出了一种利用时间-纯度两维用水图进行用水网络设计的方法，分别提出了无中间储罐和有中间储罐的设计规则。该方法把水的纯度作为一维，把时间作为另一维，从而更好地同时描述间歇用水过程的时间特性和杂质特性。它首先通过水级联分析技术确定间歇过程用水网络的夹点及最小公用工程，然后利用时间-纯度图和设计规则来合成用水网络，对有储罐的情况，确定了储罐的数量与容量，最后利用时间-水网络图描述了所合成的最优间歇过程用水网络，并探讨了用水过程流量对网络的影响。通过文献实例计算，表明该方法简单、直观、有效。

Abstract

A new time-purity two-dimensional water-using diagram was presented to synthesize water network for batch processes. In the diagram y-axis was water purity and the x-axis was time.Design rules with or without storage tank were presented respectively.The diagram could clearly describe water-using batch processes.The method firstly determined the pinch point and the minimum utility targets of the batch processes by the water cascade analysis technology

then synthesized the water network by using the diagram and rules

and then determined the number and volume of storage tanks for batch processes with storage tanks

and lastly described the synthesized optimum water network by the time-water network diagram.The influence of the water network by the flowrate demand of a water-using process was also discussed.Calculation of two literature examples showed that the method was easy

effective and efficient.
