| Summary: | The interest of treating natural gas at high pressure and high carbon dioxide (CO2) concentrations has been increasing to exploit CO2 rich natural gas reserves. Chemical absorption using alkanolamines in a packed column has been regarded as the most established CO2 capture technique. In modelling this system, the Pandya’s rate-based model is the most widely implemented approach to simulate the CO2 absorption process using alkanolamine solutions. However, the studies are limited to the conditions of low pressure (≈ 1 atm) and low CO2 loadings (e.g. < 0.5molCO2/molMEA). At the conditions of high pressure and high CO2 loadings, the real CO2 absorption phenomena is more complex which has not been reflected by the model. Nevertheless, a few of the modelling studies had tried to extend the model using correction factors derived from the experimental data. |
