“…The works of Johns (1977), and Johns and Romero (1979) were aimed at the early stages of process development when it is not feasible to optimize equipment dimensions, temperatures, pressures, etc. They qualitatively represent streams within their process by using a number of binary 0/1 flags.…”

Process synthesis is the step in design where the chemical engineer selects the component parts and how to interconnect them to create his flowsheet. This paper reviews the rapidly growing process synthesis literature of over 190 articles, almost all of which have been produced in the last decade. The paper first introduces the nature of the synthesis problem and outlines the variety of approaches which have appeared to solve aspects of it. The problems include developing a representation, a means to evaluate alternatives, and a strategy to search the almost infinitely large space of possible alternatives. As the article demonstrates, effective solutions are very dependent on the nature of the synthesis problem being addressed. The article covers in detail the following five synthesis topics: chemical reaction paths, separation systems, heat exchanger networks, complete flowsheets, and control systems. Readily apparent are the development of industrially significant insights to aid in the design of heat exchanger networks. Reasonable progress exists in the synthesis of separation systems based on nearly ideal distillation technology and in the development of computer aids by chemists for reaction path synthesis leading to desired complex organic molecules. More work is needed for the remaining areas to become industrially significant.

“…Simple sharp separation problems are well characterized using this representation and are the type of problem first considered by Johns (1977). It is doubtful the approach is suitable for heat exchanger network synthesis.…”

This paper addresses the synthesis of distillation column configurations to separate nonazeotropic multicomponent mixtures containing N components. It is shown that, for sharp separations of an N-component mixture, it is possible to develop a superstructure that takes into account all of the possibilities, from thermally linked systems with only one reboiler and one condenser to sequences with only conventional columns [2(N -1) condensers and reboilers]. All of the partially thermally linked superstructures are included. The superstructure is systematically generated using the state task network (STN) formalism, in which only the tasks that can be performed are specified, but not equipment. A set of logical relationships between tasks is proposed that allows only feasible configurations that use the minimum number of column sections and that takes into account the fact that the minimum number of column sections and the number of heat exchangers are not independent. The superstructure is modeled using generalized disjunctive programming independent of the equations that represent each of the tasks (shortcut, aggregated, or rigorous models). In this paper, the procedure is illustrated using a modified version of Underwood's equations proposed by Carlberg and Westerberg (Carlberg, N. A.; Westerberg, A. Temperature Heat Diagrams for Complex Columns. 2. Underwood's Method for Side Stripers and Enrichers.
