AN INTEGREATED APPROACH TO PROCESS PRODUCT DESIGN AND SYNTHESIS BASEDON PROPERTIES-PROCESS RELATIONSHIP/

A combined methodology employing appropriate physico-chemical properti es' estimation methods, the process synthesis algorithm of Jaksland et al. (1995a) and the product design algorithm of Constantinou et al. ( 1995) is presented. The new methodology addresses the question of inte gration of design and control in the early stages of process design by establishing relationships between physico-chemical properties, proce ss design and process control. In each case, a common set of propertie s and variables that promote the integration, are identified. The impo rtant features of the new methodology are: properties are classified w ith respect to process synthesis, product/process design and control; identified relationships between properties, process synthesis, proces s/product design and control are exploited; and finally, an analysis/v alidation step is employed to screen/confirm the generated alternative s. Two examples of application of the methodology are also presented.
