Abstract
CO2 removal by the blended amine solution of piperazine (PZ) and methyldiethanolamine (MDEA) with the various molar concentration ratios in a rotating packed bed (RPB) was modelled using MATLAB linked to Aspen Plus. All the required correlations for the RPB in addition to the mass and energy balances were written in MATLAB while the demanded physical and transport properties were extracted from Aspen Plus. The similar operating conditions and compositions in the reported experiments were used to run the model by the two-film theory for mass transfer as steady state, while the impact of five different parameters on the CO2 absorption efficiency was examined to validate the model. The modeling results are in good agreement with the experimental data for which the average absolute deviation is less than 7.0%. The process analysis revealed that rotational speed and PZ concentration have the most significant effects on CO2 absorption efficiency.Citation
