The issue of environmental sustainability has prompted the batch chemical industries to switch from end-of-pipe treatment to waste minimization as top priority in tackling the pollution problem. In this paper, we introduce a novel simulation-optimization framework that integrates different process systems engineering (PSE) methodologies – process graph (P-graph), hierarchical design strategy, W...

A bst r Ac t Sustainability has recently emerged as a key issue in process systems engineering (PSE). Mathematical programming techniques offer a general modeling framework for including environmental concerns in the synthesis and planning of chemical processes. In this paper, we review major contributions in process synthesis and supply chain management, highlighting the major optimization app...

Model-based systems engineering (MBSE) is part of a long-term trend toward model-centric approaches adopted by many disciplines. We establish the need an MBSE approach reviewing importance, complexity, and vulnerability U.S. chemical supply chains. discuss origins, work processes, modeling approaches, supporting tools discipline (SE) limitations Process Systems Engineering (PSE) framework. make...

Carbon dioxide (CO2) emissions contribute considerably towards increasing greenhouse effect. capture and storage can reduce CO2 to a great extent but lacks economic feasibility. The feasibility of could be boosted by utilizing the captured gas produce valuable end products. is highly stable molecule; therefore, special catalysts elevated conditions temperature pressure are required for its conv...

This paper highlights for a class of chemical products, the design process, their design with respect to the important issues, the need for appropriate tools and finally, lists some of the challenges and opportunities for the process systems engineering (PSE)/computer-aided process engineering (CAPE) community. The chemical products considered belong to the following types: chemical/biochemical...

1. ABSTRACT Domain speciic Problem Solving Environments (PSEs) are the key new ingredients that will aid in the widespread use of Computational Science & Engineering (CS&E) systems. Each PSE consists of a well deened library that supports the numerical and symbolic solution of certain mathematical model(s) characterizing a speciic discipline, together with an easy to use software environment.
