单杂质用水网络集成对能量集成影响规律探索

Focused on water-using network with single contaminant and temperature and concentration requirements,this paper explored the effects of different configurations of water-using network on the target of energy integration.Sequential design method is adopted,i.e.,the water-using network is first designed to minimize both the freshwater usage and the total connection number simultaneously,and energy integration is then carried out to minimize both the hot or cold utility consumption and the total number of heat exchangers.All possible alternative configurations of water-using network are identified in this work by adopting the‘Solution pool’ technique provided by Solver Cplex coming along with GAMS software,and energy integration is carried out for each alternative configuration.A case study was provided in this work to illustrate the effectiveness of the proposed method.The preliminary conclusion drawn from this work is that different configurations of water-using network of same quality have only a little effect on the total number of heat exchangers while no effect on the minimum hot or cold utility consumption.water-using
