摘要：

This paper introduces necessary conditions of optimality for water-using networks in refineries and process plants. These necessary conditions correspond to the optimal water allocation planning (WAP) problem that considers wastewater reuse on the basis of a single contaminant and where the objective is to minimize the total water intake. The conditions under which degenerate solutions are possible are also identified. Examples are discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
