Many thermodynamic models used in practice are at least partially empirical and thus require the determination of certain parameters using experimental data. However, due to the complexity of the models involved as well as the inhomogeneity of availa

An integrated reaction–distillation process for the production of methylal from aqueous, methanolic formaldehyde solutions is developed. The process consists of a serial connection of a reactor in which the feed is converted to chemical equilibrium

Since experimentation is expensive with increasing computation power the significance of modeling, simulation, and optimization in process development has grown. Quite often in such models some parameters are uncertain, e.g., due to high variance in

For use in sensitivity studies and robust optimization, uncertainties in thermodynamic models have to be considered in simulations. Instead of using less vivid confidence intervals of the models’ fitting parameters, this work proposes a perturbatio

The development of chemical processes is based on both experiments and process simulations. Data evaluation and reconciliation, model development and validation, and design of experiments are essential steps in this procedure. The different tools and

In most distillation problems, the desired products are located at the singular points of the vapor–liquid equilibrium, i.e. pure components or azeotropes. The effort to approach these points depends on the specified purity of the product and tends

In this work a short-cut method for the conceptual process design is presented which enables an analysis of arbitrary flow sheets consisting of reactors, distillation columns, decanters, mixers, splitters, and component splitters. It is based on prev

A short-cut method for the conceptual design of processes consisting of distillation columns and decanters is presented. It extends the previous work on homogeneous distillation columns and processes ( Ryll et al., 2012b ) to heterogeneous distillati

A method for the analysis of flowsheets consisting of an arbitrary number of distillation columns and mixers in conceptual process design is presented in this work. The required information on the process is reduced to a minimum: besides the fluid pr

In this work a new method – the convex envelope method (CEM) – for the reliable determination of fluid phase diagrams is presented. The method yields the entire phase equilibrium diagram and does not rely on the determination of individual equili
