TLDR
In this paper, a geometrically-based approach for determining the attainable region of a single exothermic reversible reaction was proposed. But the results were applied to an extensively investigated example and shown to give an improved value of the objective function.Abstract:
Recently developed geometrically-based ideas for determining the attainable region have been applied to single exothermic reversible reactions where the only processes allowed are preheating a portion of the feed, reaction, and mixing. The following system of reactors in series in general defines the boundary of the attainable region: a CSTR, a plug flow reactor, a differential reactor which does not in general follow the optimal temperature profile, and finally another plug flow reactor. Analytical conditions have been derived for the operating parameters of these reactors. This system of reactors gives a limit against which other reactors which use only the above-mentioned processes can be compared; for example a cold-shot-cooling reactor. This new approach combines several previous results into a cohesive theory. The ideas are applied to an extensively investigated example and shown to give an improved value of the objective functionread more

Feasible region for a countercurrent cascade of vapor-liquid CSTRS
TL;DR: In this paper, the attainable region approach for reaction-mixing systems was applied to systems with simultaneous reaction and separation, and a model developed for a countercurrent cascade of two-phase CSTRs can be considered as a surrogate for the stripping or rectifying sections of a reactive distillation column.

Choosing optimal control policies using the attainable region approach
TL;DR: In this article, the authors extend the attainable region approach to situations where the rate vector depends on a control parameter, such as temperature, and derive equations that describe the optimal control policies.
Synthesis of chemical reactor networks
TL;DR: This study reviews both methods for reactor network synthesis but focuses on advances with the targeting approach, which effectively captures all possible reactor structures and finds the bounds on the performance of a reacting system.

Multiperiod reactor network synthesis
TL;DR: It is shown that reactor networks designed under uncertainty, in general do not follow AR properties, and more general reactor types may be needed to solve the reactor network synthesis problem under uncertainty.
