Experimental verification of Equilibrium-Stage and Rate-Based Simulations
article
In this article, pilot plant data for CO2 post-combustion capture are discussed and compared with modelling results. The objectives of this paper are to evaluate the overall performance of the CO2 capture pilot plant using both experimental and simulation results. In addition, this work is aiming to assess the performance of two different modelling approaches (equilibrium-stage and rate-based) in representing the CO2 capture process performance and requirement. Furthermore, an extended parametric study was carried out to evaluate both experiments and simulation tools. This work indicated that there are no major differences between the two modelling approaches in predicting the overall capture process behaviour (macro scale) for this pilot plant case. However, the simulation of the absorber and stripper columns demonstrated that the rate-based model gives a better prediction of the columns temperature profiles and mass transfer inside the columns compared to the equilibrium-stage approach (micro scale). As a result, for a detailed process design or understanding of the mass and energy profiles in the absorber and stripper columns, the rate-based approach should be applied. It was concluded that both modelling approaches can be used for predicting the capture process overall behaviour and requirement for pilot plant scale as well as for industrial scale application.
