摘要：AbstractCCP is the process of capturing and storing CO2away from the atmosphere. Out of the three available methods of capturing CO2, this study focused on Post-combustion process. The Mass balance equations of the flue gas was modelled as a PDE and then reduced to an ODE by the application of Numerical Method of Lines. The equation was discretized to 0.8 m. Mono-ethanolamine, Potassium Carbonate and Chilled Ammonia were studied to investigate their absorption capacity to capture CO2. Two specific mass transfer area correlations were used in order to validate the results. The results followed the same trends with minimal error of less than 21%. Discretization of 1 m was done for the absorbent which captured the highest amount of CO2in order to further validate the results. The results corresponded well with each other. MEA has proven to be the best absorbent in capturing Carbon dioxide than the other two absorbents.
