Design of water-using networks with multiple contaminants by determining concentration order of streams

PAN Chunhui1,2,SHI Jing1,LIU Zhiyong1 (1School of Chemical Engineering,Hebei University of Technology,Tianjin 300130,China;2Department of Chemistry,Cangzhou Teachers’ College,Cangzhou 061001,Hebei,China)  
In the design of water-using networks of multiple contaminants,there are two key steps:determining the process executing order and allocating the process streams.In this paper,a new concept,overall concentration potential of demand (OCPD)for the process stream is proposed.The OCPD of a stream reflects the concentration order of a stream compared to all the other streams (including both demand streams and source streams).Compared to the concentration potential concept proposed by Liu et al(2009),OCPD can compare the concentration order of a demand stream and that of a source stream.In the design,the process executing order is determined by the values of OCPDs of the demand streams.The process with the lowest inlet OCPD is executed first.When satisfying a demand stream of the process being executed,the source stream with the largest quasi-allocation amount,which is defined in this paper,is used first.A few literature examples are investigated.The results show that the amounts of fresh water consumptions are very close to the minimum fresh water targets,the structures of the designs obtained in this work are not complex compared to that obtained in the literature,and the calculation of the proposed method is very simple.
