Current industrial practice for chemicals manufacturing is reviewed and the motivation for building large, integrated production sites discussed. The concept of distributed manufacturing (chemical production in situ) as an alternative philosophy is then introduced. Potential economic, safety, logistic and environmental benefits are considered together with circumstances when the application of such a manufacturing system may be favourable. The problems of realising a distributed plant are briefly discussed in order to highlight those design aspects of interest in a process systems methodology. The integrated design problem is discussed in the context of a distributed plant and literature in this area is reviewed. It is concluded that any integrated design procedure for distributed plants should explicitly consider the dynamic operation of the process at the process design stage. Potential tools for the combined optimisation of the plant design and operation are reviewed and dynamic optimisation is deemed the most appropriate alternative. A procedure for the integrated design of distributed plants is presented. The rationale for the procedure is to develop plant designs which operate feasibly in the face of frequent and potentially large changes in demand. The procedure consists of two stages. In the first stage, a candidate process structure is developed using a combination of heuristics and economic bounding properties. A dynamic optimisation formulation is then applied to determine the economically optimal cyclic operating procedure for the candidate structure. The design procedure facilitates the development of an effective design and the corresponding optimal operating strategy. The proposed design framework is demonstrated by application to three representative case studies: a continuous multiproduct plant, an integrated chemical wastewater treatment system and a distributed reactor network. The results of the work presented are reviewed and some needs for further work identified.
