Abstract:In addition to concentration of contaminant, stream properties such as toxicity, pH, chemical oxygen demand are also important characters indicating water quality. Such situation would make the design of water-using process just according to contaminant concentration fail to meet the increasingly stringent production and environmental requirements, and prompt it to be necessary to consider the simultaneous integration of stream properties in water network synthesis. In this paper, a superstructure involving property interceptors in semi-continuous operation is established for the integration of batch water network with concerning environmental constraints and the minimum total annual cost target. The property interceptors can operate at various treating rates in different time intervals, and a series of tanks are placed before and after the interceptors to satisfy the batch operation of process sources and sinks, in assistance of which the sources in the tanks in front of interceptors are allowed to be reused to sinks directly without treated by interceptors. The calculation results show that the proposed method can effectively reduce the total annual cost and reduce the number of interceptors, which verifies the effectiveness and superiority of the proposed method. ?
