Determination of optimal design and control decisions for reactor-separator systems with recycle

Two simple yet powerful techniques used within a new model-based methodology for integrated process design and control (IPDC) to determine optimal design decisions are presented. These are attainable region (AR) and driving force (DF) techniques whose concepts are used to find the optimal design...
