Abstract The development of absorption processes for carbon capture needs studies of process scale-up and modeling CO2 absorption was measured in 200 mm and 600 mm diameter packed columns. An effective mass transfer area correlation for structured packings was used to simulate the process with a rate-based method and different mass transfer models. The results show that the most suitable mass transfer model is the film resistance model with average relative errors in the CO2 mole fraction of 1% and 3% in the two columns. Thus, this mass transfer model and mass transfer area correlation are valid for structured packings and CO2 absorption in various size columns could be predicted by this simulation.
