(606f) A Modular Approach to Process Integration and Intensification
In this work, we propose a systematic approach for process synthesis, integration, and intensification based on recent extensions of the Generalized Modular Representation Framework [8-11]. Herein, the chemical processes are represented as aggregated multifunctional mass/heat exchange modules with which intensification possibilities can be discovered without a pre-postulation of equipment or flowsheet configurations. Driving force constraints, derived from total Gibbs free energy change, are employed to characterize mass/heat transfer feasibility by exploiting the general thermodynamic space, and thus result in a more compact modular representation of the chemical systems. Mass and/or heat integration are simultaneously addressed in the superstructure representation of the modular network, without pre-postulation of steam properties as rich/lean streams or hot/cold streams. The resulting synthesis problem is formulated as a mixed integer nonlinear programming optimization problem (MINLP), where both process cost performances and environmental regulations can be accounted for. Three case studies are presented to showcase the proposed approach for process integration and intensification, namely: (i) heat-integration process, (ii) extractive separation process with heat & mass integration, (ii) reactive separation process.
