Abstract

In the last two decades, Mass Exchange Network (MEN) synthesis has been explored to design mass exchanger system to systematically minimize Mass Separating Agents (MSAs) and waste in process industries. Heuristic approach through pinch analysis is a convenient method to analysis mass-based separation network synthesis i.e. the mass transfer between rich and lean stream (process and external MSAs). This research introduces the notion of targeting and design of MEN simultaneously through a new pinch-based graphical technique. The new method aims to sort out the limitation of previous developed graphical approach such as Composite Curves (CC) and Grid Diagram (GD), where targeting and network design of MEN problem is done one at a time and independent of each other except being guided by the pinch point. The framework of this research consists of data specification, simultaneous MSA targeting and network design, and also impact of the design scenarios on capital. Continuous Individual Plot (CIP) approach has been developed to map continuous stream profiles of rich streams and lean streams involved in the MEN problem. Along with introduction of Mass Allocation Network (MAN) diagram, these new tools overcome sequential step practiced by current pinch-based approaches in synthesizing MEN.A set of heuristics are also produced to guide the procedure of these new tools. Systematic steps to analyze capital cost early during MSA targets of stream–matching are also provided. The research has demonstrated the ability of the new method with two industrial-based literature case studies for continuous system with single transferable component. The minimum MSA targets achieved are exactly the same as previous CC techniques while network design can now been translated directly from the targeting tool i.e. the CIP plot.
