Abstract

In this work a methodology to reduce pollutant emissions in industrial processes by water reuse is proposed. The pollutant emission reduction is achieved by the synthesis of mass exchange equipment (MEN). Pinch Analysis is used. The proposed methodology to the MEN synthesis initially sets the targets relative to the minimum global cost, the minimum number of mass exchange equipment and the minimum water flowrate. After the synthesis step, the MEN is evolved, by identifying and breaking mass exchange loops, without water flowrate changes. After the evolution step, an economical analysis is achieved. An industrial case published in the literature was used to show the efficiency of the proposed methodology. Results reflect the importance of economical analysis jointly with the MEN synthesis.
