TL;DR: In this article, a model of an industrial chemical process for the purpose of developing, studying and evaluating process control technology is presented, which is well suited for a wide variety of studies including both plantwide control and multivariable control problems.

TL;DR: In this article, the authors stress the importance of selecting the right plantwide control structure and the need for a formalized approach that can encompass the many issues that arise in plant-wide control design.

TL;DR: The roles of simulation and laboratory experiments are highlighted, and alternative ways of teaching control in the future are described, including problem-based learning, case studies, and use of multimedia classrooms.

TL;DR: In this paper, the authors focus on DWCs as a ternary separation technology for hydrocarbon mixtures relevant to the chemical and refining industries and conclude that, although achieving stable DWC operation is certainly possible, the development of a comprehensive framework that incorporates (multiple and often conflicting) process operating objectives, and equipment and process constraints, into a transparent control strategy remains an open research question.

TL;DR: The role of distillation columns as a unit operation that separates components usually makes the operation of the distillation column central to the control of component inventories within a process as discussed by the authors.
