“…For the determination of the reaction kinetics, the data of von Harbou et al were used again. In order to describe the heat exchangers, Nusselt correlations from the VDI Heat Atlas were employed. − It should be mentioned that only few Nusselt correlations are available for the condensation process . The correlations are developed for simple single tubes.…”

Reactive absorption is a separation process widely used in the environmental protection area. In this process, undesirable gaseous components are captured by chemical reaction in a solvent while the loaded solvent is regenerated in a desorption unit. Both process steps, absorption and desorption, take place simultaneously and strongly interact resulting in a very complex process behavior. To ensure stable and safe process operation, even in the presence of instabilities or malfunctions, understanding of the dynamic process behavior is essential. In this work, a pilot plant experimental study was carried out in which three different stepwise changes of the solvent flow rate were made. The results of this study were used as a validation basis for the recently developed novel dynamic model of reactive absorption/desorption processes in a closed-loop configuration including the plant periphery. The deviations between experimental and simulated outlet gas concentrations were found to be below 10% for all experiments. The validated model was used to investigate the influence of the periphery on the process performance.
