Application of Composition Interval Diagram for Cost Minimization in Mass Exchanger Networks

This article presents a technique of reducing the Total Annual Cost (TAC) in mass exchange network synthesis (MENS). The method can minimize the pollutants getting into the environment through selective transfer of such wastes from rich process stream to lean process stream. It also enables the product to be obtained in their pure form. The method was applied to two problems with the aim of reducing the total annual cost (TAC) of production. The results obtained in this study demonstrate that the approach adopted in this paper is capable of giving costs that are comparable with other techniques in literature
