Process Modeling and Simulation for Optimizationof Operating Processes

摘要

During the last decade, a major shift has begun in chemical industry, since thereis an urgent need for new tools that are able to support the optimization ofoperating technologies. This trend is driven by the new tools of informationtechnology. Approaches of this shift differ from company to company but onecommon feature is that communication between design, manufacturing,marketing and management is centered on modeling and simulation, whichintegrates not only the whole product and process development chains, but allthe process units, plants, and subdivisions of the company. These approachesare under continuous development. Among the wide range of possibleimprovements, this paper focuses to two frequent imperfections: (I) developedand refined process models are used only in advanced process control system(APC) integrated into distributed control system (DCS) and operator trainingsystems (OTS), and not for detailed analysis and optimization, and (ii) optimalprocess operating points of these chemical plants are adjusted only at the designand test phase of a new technology, but optima moves with time, new catalystsystem, lower price of reactants, claim for new or higher purity products, etc.The aim of this paper is to review, how to manage process optimization, and toshow our process simulator based on the chemical engineering model of thetechnology. This paper will present a case study to demonstrate thetechnological and ecological benefits of the analysis and optimization of an
