A General Column Model in CO2SIM for Transient Modelling of CO2 Absorption Processes

In this work, a dynamic model is developed in the CO2SIM framework for transient modelling of CO2 absorbers and desorbers. Validation of code towards pilot data is presented, and the applicability of the model is shown with two examples of usage. Emphasis has been on developing flexible coding architecture for further development into dynamics and for a sequential modular dynamic handling of information when incorporated into a dynamic network solver. The model compares well with the pilot plant measurements and is numerically robust. The methods developed for handling pilot plant data and updating events (as e.g. multiple changes in the feed flow-rate) minimize the manual work for the engineer.^p
