Process intensification by model-based design of tailor-made reactors

Optimization of the direct synthesis of dimethyl ether from CO2 rich synthesis gas: closing the loop between experimental investigations and model-based reactor design

“…The parameters A and B associated to eqn (6) for the calculation of the equilibrium constants (K f, j ) are reported in Table 2 for reactions (1) to (3).…”

“…Consequently, models are often simplified by a number of context dependent assumptions that facilitate their solution. In the context of model-based optimization of chemical reactors as for example during multi-level reactor design (MLRD), [1][2][3] a proper degree of detail is crucial. This so called model adequacy is especially relevant when the models are extrapolated.…”

Challenges and Opportunities to Enhance Flexibility in Design and Operation of Chemical Processes

“…First methodological approaches to consider flexibility during the design stage of chemical reactors are available. These approaches are based on the concepts of elementary process functions [37]. Maußner et al [38] use this concept for a feedstock-tolerant design and Fischer et al [39] for a capacity-flexible design of chemical reactors.…”

Separation Units 4.0 – Trennapparate heute und morgen

“…Für diesen Fall kann tolerant als flexibel in Bezug auf variierende Feedzusammensetzungen interpretiert werden. Das Verfahren basiert auf dem Konzept der EPFs ( elementary process functions ) zur Synthese optimaler Reaktorkonfigurationen. Zum Design optimaler Reaktoren für tolerante Prozesse wird das Verfahren dahingehend erweitert, dass die EPFs nicht nur für einen fixen Feed optimiert werden, sondern parallel für eine definierte Variation der Feedzusammensetzung.…”
