This research is divided into two parts, examining continuous or batch processes. The current work on continuous processes is focused on developing a more general procedure for the systematic synthesis of process flowsheets that will identify the most important process alternatives (including waste minimization alternatives), the dominant design variables, and the minimum energy consumption for each alternative for continuous, vapor-liquid-liquid-solid processes for the production of nonpolymeric materials. This work is an extension of the hierarchical synthesis procedure previously developed for vapor-liquid processes. A new superstructure for continuous process flowsheets, along with an extended set of rules for the classification of components, with special attention to waste minimization, and solvent selection is described. The work on batch processes is focused on developing new procedures for the design and scheduling of multiproduct batch plants. The approach is based on simulated annealing and the solution of the optimal sequencing problem as well as initial results on the design problem are described in this report. 4 refs., 2 figs., 2 tabs.
