The system separation method for the optimal target of heat exchanger network synthesis with multiple pinches

Abstract

This article proposes a new method to the optimal target of a heat exchanger network synthesis problem of which data feature multiple pinch points. The system separation method we suggest here is to subdivide the original system into independent subsystems with one pinch point. The optimal cost target was evaluated and the original pinch rules at each subsystem were employed. The method is illustrated with two examples of which data features two pinch points.
