Abstract
A novel modular integrated framework is developed in this work to perform process synthesis and optimization based on a sequential process simulator. The modular integrated framework consists of three platforms: simulation, parameter and optimization platforms. This framework integrates process simulator, interface program, optimization algorithm to form a multi-platform environment integrated system. In the framework, the alternative processes models are firstly established through a process simulator (Aspen Plus).After that, parameter extraction and processing are implemented by Excel with the interface (Aspen Simulation Workbook). And then the MINLP problem of process synthesis is solved by the multidisciplinary integration software (Isight). The rigorous models of chemical processes or units, regarded as “Black box”, are solved by the process simulator, rather than shortcut or aggregated models in the form of equations. Therefore, not only is the process synthesis problem simplified but also does improve the accuracy of the solution. Several examples are provided to illustrate the effectiveness of the proposed method.
