Bei Konti-Anlagen treten oft dynamischen Übergangsvorgänge, wie Anfahr-, Last-oder Produktwechsel, auf, wohingegen Automation and Optimization of Startups, Load Changes and Batch ProcessesContinuous processes show dynamics during load changes, start-up and shutdowns whereas batch processes exhibit inherent dynamics. In the past, the major concern of automating these dynamics states of process operation were safe and reproducible operation, however, today modern methods of process operation allow for the economic optimization at the same time. The automation and optimization of batch processes pose challenges in several areas: Mastering the high complexity, connecting heterogeneous components by automation, and combining extensive knowledge from both process engineering and automation during project execution. This contribution describes approaches from industrial practice and punctually academic research, which solutions for the challenges are readily available and how to implement these.

“…Ebenfalls zur Gruppe der rigorosen Optimierungsansätze zählen dynamische Optimierungsmethoden, die eine simultane Betrachtung bzw. Steuerung von Zustandsgrößen ermöglicht . Wenngleich bereits in den 1960ern Arbeiten über dieses Thema erschienen, finden dynamische Optimierungskonzepte erst durch immer leistungsfähigere Computersysteme breite Anwendung.…”

In dieser Arbeit wird ein modellbasierter Ansatz für die Entwicklung maßgeschneiderter, energieeffizienter chemischer Reaktoren vorgestellt. Hierzu wird eine praktikable Größe zur Beschreibung der Energieeffizienz eingeführt und als Zielfunktional der Optimierung genutzt. Zur Veranschaulichung des Ansatzes und der energetischen Bewertungsgröße wird das neue Zielfunktional verwendet, um einen neuen Reaktor für die Anilinsynthese zu entwickeln. Die Energieeffizienz konnte dabei im Vergleich zu herkömmlichen industriellen Anilinreaktoren um das Doppelte gesteigert werden.

“…Though a lot of work has been reported recently in the literature on batch process control and optimization (Abel et al 2000, Srinivasan et al 2003, Flores-Cerrillo and MacGregor 2003, Chin et al 2004, there is still a lack of understanding of their system-theoretical properties. Due to the finite-time nature of batch processes, the standard definitions of properties such as stability, controllability and observability cannot be used.…”

Improving the performance of batch processes requires tools that are tailored to the specificities of batch operations. These include a mathematical representation that explicitly shows the two independent time variables (the run time t and the run index k) as well as the two types of outputs (the run-time and run-end outputs). Furthermore, corrective action can be taken via both on-line and run-to-run control. This paper investigates the important notions of stability and controllability for batch processes, where it is shown that a value rather than a yes-no answer needs to be considered. The tools required for evaluating these properties are readily adapted from the literature. Finally, the various control strategies are illustrated via the simulation of a semi-batch reactor, and references are made to the appropriate tools for evaluating stability and controllability.
