    Notes: Reactive Distillation Processes Reactive distillation, i.e. the simultaneous implementation of reaction and distillation in a counter-current column, is a promising alternative to the conventional sequential processes. In a preceding paper the effective phase equilibrium of a reactive distillation was studied with a special focus on the determination of so-called reactive azeotropes. In this contribution, a knowledge of these thermodynamic fundamentals is applied to the conceptual design of reactive distillation processes. Furthermore, some process examples of technically important processes are presented.

    Notes: Thermodynamic Fundamentals of Reactive Distillation Reactive distillation means the simultaneous implementation of reaction and distillation in a counter-current column. The effective phase equilibrium is very complex since the chemical equilibrium is superimposed on the vapor liquid equilibrium. The paper focuses on the calculation and presentation of this equilibrium using so called reactive distillation lines. This leads to a clear explanation for the existence of reactive azeotropes and to a simple method for the determination of the concentration of these azeotropes. The effectiveness of this method is demonstrated on several mixtures with different reaction mechanisms.

    Notes: In the era of globalization, the speed of change is closely related to both the population growth in developing countries and their desire to close the economic gap with the western hemisphere. Chemical engineering is considered a significant contributor in finding solutions to the subsequent challenges of food supply, energy demand and environmental impact. National economies and their constituent enterprises require qualified engineers to meet these urgent and economically demanding challenges. At present however, neither the number of engineering students nor the national focus of university education seem appropriate to cover future requirements. On the scientific level, new modelling techniques, CFD and novel system orientied methods provide a perpective for both product and process improvements. In addition to their technical ability, professional engineers must emply a flexible approach as well as soft skills to put innovative solutions into practice. This paper illustrates and details the contents of the „Memorandum Verfahrenstechnik“ [3], a list of recommendations which was prepared by representatives of both industry and university.

    Notes: Es wurde ein Verfahren zur großtechnischen Herstellung von Äthylen aus Rohöl oder Schwerölfraktionen entwickelt. Das Rohöl wird in einer Wirbelschicht aus Kokskörnern bei etwa 700 bis 750 °C gekrackt. Die zur Aufrechterhaltung dieser Temperatur nötige Wärme gewinnt man durch die exotherme Reaktion des bei der Krackung entstehenden Petrolkokses mit Sauerstoff, welcher in die Wirbelschicht eingeblasen wird. Das Verfahren liefert gute Ausbeuten an niederen Olefinen und nur solche Nebenprodukte, die sich in einem chemischen Werk weiterverarbeiten lassen.
