A dynamic model for the chemical absorption of carbon dioxide in Monoethanolamine is developed and implemented. The model includes absorption tower, de-absorption tower, reboiler, condenser and rich/lean heat exchanger. The chemical reactions of MEA and CO2 are included in the model and the vapour liquid equilibrium for CO2 is described by henrys law. The concentrations of MEA, H2O N2 and O2 in both phases are calculated with the Peng Robinson equation of state utilising the individual species fugacities. The model was solved as a PDE, for both absorption and de-absorption columns implementing the method of lines. The full model was simulated in Matlab and results where obtained that agree with other published values.
