Modeling and simulation of chromatographic separation in Modelon Impact

Abstract: The aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. The model is successfully implemented and done in a step-wise manner. The comparison between the two simulations are near flawless, but some variations can be seen as load time of the column increases. While not conclusively deduced, the problem most likely lies in how the two different solvers work. Another aim is to use the functionality of Modelica and create different models in order to create a more accurate setup seen during laborative trials. These models range from the column and pump that have previously been modeled in the original MatLab code to controllers, valves and tubing that reflect real experimental setups. The interconnectivity between models are successful, but due to variable overlap some setups had to be altered in order to complete the simulations. While Impact has proved to be more than capable to simulate chromatographic processes and handle user-created sub-models, there is still room for investigation of it as a tool for finding parameters or handling more complex models.
