Plant-Wide Process Improvement In Cooperation Of Mathematical Optimization Using The Mipt Algorithm In Chemcad (Tm)

This paper presents a systematic approach for the improvement of existing complex processes in chemical industry in order to increase their efficiency. As a result, modifications of process configurations are developed. Due to their implementation several internal stream compositions may be changed. In order to guarantee all demanded product specifications, new operating points need to be found. Hence, a method based on the global optimization algorithm MIPT has been developed in Matlab (TM). The process simulation software ChemCAD (TM) has been linked to Matlab (TM) in order to solve the optimization problem. The developed method is applied to a complex example process. The influence of changing feed composition on several process variables is pointed out.
