“…7 In a batch extractive distillation for fine chemicals processing, for example, CAMD has been shown to identify a solvent that makes it possible to meet purity requirements, and that minimizes the time required for separation, with gains in throughput/productivity of at least 15%. 8 The extension of CAMD techniques to reactions has the potential to facilitate the task of finding good solvents, and to uncover unexpected choices. The key objective in using such an approach is to identify choices of solvent molecules that offer good overall performance and meet the plethora of criteria that constrain solvent choice.…”

“…This allows the quick evaluation of the separating agent put forward by the master problem, before the solution of the primal problem. This work has been applied to absorption processes and extended to dynamic models (Giovanoglou, Barlatier, Adjiman, Pistikopoulos & Cordiner, 2003). Another approach has been developed by Marcoulaki & Kokossis (2000), who have used a simulated annealing approach to integrate solvent and process design.…”

“…44 To handle more general design problems, one can adopt the approach of Buxton et al 8 who modified the generalized Benders decomposition (GBD) algorithm 45 : they introduced several steps prior to the solution of the primal problem, including a series of property tests that form a subset of the CAMD problem constraints, the initialization of various sets of equations in the process model, and mass-transfer feasibility tests, in which the process operating conditions were assumed to be fixed a priori. This approach was extended to tackle mixed-integer dynamic optimization problems, 46 to enable the simultaneous design of a batch process and the associated solvent. In these studies, the highly-nonlinear UNI-FAC model 15 was combined with the ideal gas equation to represent the relevant phase equilibria.…”

“…Several novel tests are embedded within a modified outerapproximation (OA) 49,50 algorithm to solve the MINLP, akin to the general principle of integrating tests into a modified GBD algorithm deployed by Buxton et al 8 and Giovanoglou et al 46 The tests we develop differ from these earlier approaches, however, as the feasibility of the process is assessed for combinations of the values of the process and molecular variables, rather than for values of the molecular variables alone. When a new solvent is generated at a major iteration of the modified OA algorithm, the tests help to ascertain the feasibility of using the solvent in the process, before solving the process optimization problem (primal problem) for the fixed solvent.…”
