Mikroverfahrenstechnik: Komponenten – Anlagenkonzeption – Anwenderakzeptanz – Teil 3

Microtechnology: Components – Plant Concepts – User Acceptance Many activities over the last five or so years have focussed on the thus far underdeveloped field of carrying out reactions on small scales. Due to the rapid development of new components, this paper touches on recent developments only in a compressed form. An important point is the analysis of possible plant concepts for microreactors and whether these are a sensible option. Due to the enormous size difference between the microchannels and the fluid periphery of possible components this is not just a technical question, it touches on the microtechnology concept as a whole. The direction in which the field should be developed and which measures can be taken to influence its development, are questions that are addressed here with respect to the big industrial interest in microreactors.     

Verwaltung und Wiederverwendung von Modellen im industriellen Entwicklungsprozess

The Management and Reuse of Models in Industrial Design Processes The use of model‐based methods for the support of the planning, designing, and operating of chemical processes and plants has recently gained increasing importance in the daily work of the process engineer. However, it is becoming more obvious that already the design of mathematical models by the use of standard flowsheet simulation tools requires an experienced designer. Therefore, the developed models not only represent a value considering the resources required for their development, but especially they contain a large amount of knowledge of an enterprise about its products and production processes. It is hence reasonable to lower the costs of model development by reuse of models and experiences. This report gives an overview about the systematic long‐term management and use of mathematical models. Some motivating scenarios help to derive requirements for a model management system and to evaluate existing methods and tools. From these results, the concept of a model management system is derived. After presenting a prototypical implementation, this article concludes with an outlook.
