Diethanolamine (DEA)-promoted potassium carbonate process for CO2 removal is modelled using ratebasedapproach and Electrolyte NRTLmodel. Acceptable agreements between the simulation results andthe experimental data are achieved. The effectiveness of monoethanolamine (MEA), diglycolamine(DGA), diisopropanolamine (DIPA), and methyldiethanolamine (MDEA) as promoters are investigated. MEA shows promising performance for CO2 removal. The CO2 absorptions by DGA and DIPA are goodenough, but their prices are higher than MEA and DEA. The CO2 absorption byMDEA is not significant andit cannot be used as a promoter. A parametric study is performed to assess the effects of importantprocess parameters.
