This paper presents a review of advances that have taken place in the mathematical programming approach to process design and synthesis. A review is first presented on the algorithms that are available for solving MINLP problems, and its most recent variant, Generalized Disjunctive Programming models. The formulation of superstructures, models and solution strategies is also discussed for the effective solution of the corresponding optimization problems. The rest of the paper is devoted to reviewing recent mathematical programming models for the synthesis of reactor networks, distillation sequences, heat exchanger networks, mass exchanger networks, utility plants, and total flowsheets. As will be seen from this review, the progress that has been achieved in this area over the last decade is very significant.

The reactor network synthesis problem involves determining the type, size, and interconnections of the reactor units, optimal concentration and temperature profiles, and the heat load requirements of the process. A general framework is presented for the synthesis of optimal chemical reactor networks via an optimization approach. The possible design alternatives are represented via a process superstructure which includes continuous stirred tank reactors and cross flow reactors along with mixers and splitters that connect the units. The superstructure is mathematically modeled using differential and algebraic constraints and the resulting problem is formulated as an optimal control problem. The solution methodology for addressing the optimal control formulation involves the application of a control parameterization approach where the selected control variables are discretized in terms of time invariant parameters. The dynamic system is decoupled from the optimization and solved as a func...

Abstract: Problems with synthesis and optimization of reactor systems are considerably more complex than other process stages. The complexity is related to the complex and nonlinear behavior of the reactor systems. In this work a computational systematic procedure was developed in order to optimize ideal reactor systems. The technique of nonlinear optimization of the genetic algorithms was used. This optimization technique is based on the submission of randomly generated individuals through the algorithm. The variables chosen for the optimization were the conversion and volume of the reactor systems. The objective function to be optimized was determined by the material balance, different types of reactors and their possible combinations, in order to maximize the profit in obtaining the product wanted. To the cost function the pertinent project restrictions and the reactor’s operations that compose the system were incorporated, simplifying the solution of the problem in an unrestricted way. Nonetheless, the classic functions of the genetic algorithms found in the literature were adapted to create capable individuals in the conversion interval demanded by the problem. Two cases from the literature were studied and results are similar to those one obtained by the application of the systematic procedure developed.

ABSTRACT. In the present paper, a computational systematic procedure for isothermal Reactor Network Synthesis (RNS) is presented. A superstructure of ideal CSTR and PFR reactors is proposed and the model is formulated as a constrained Nonlinear Programming (NLP) problem. Complex reactions (series/parallel reactions) are considered. The objective function is based on yield or selectivity, depending on the desired product, subject to different operational conditions. The problem constraints are mass balances in the reactors and in the considered reactor network superstructure. A systematic computational procedure is proposed and a Genetic Algorithm (GA) is developed to obtain the optimal reactor arrangement with the maximum yield or selectivity and minimum reactor volume. Results are as good as or better than those reported in the literature. Key words: process synthesis, reactor network synthesis, optimization, reactor superstructure, genetic algorithms. RESUMO.
