Abstract

The removal of carbon dioxide due to environmental problems still is a great interest for researchers. In this study, simulation and comparative study of carbon dioxide removal by four well-known basic solvents; amino monoethanolamine (MEA), diethanolamine (DEA), methyldiethanolamine (MDEA) and aminomethylpropanol (AMP) in polypropylene hollow fiber membrane reactor with multi-physics Comsol software based on fluid dynamic calculations (CFD) are considered. Comparison of the results of adsorption simulation by four different amine base solvents in terms of length of the membrane (dimensionless) showed that the best amount of adsorption by MEA solvent is that in the present simulation 88% of CO2 gas is adsorbed by MEA. The results of the simulations are validated by comparison of the simulation results with the models given by other researchers and showed that there was an acceptable consistency between the present simulation data and the results of others. For example, solvent adsorption (MEA) in the report from the experimental results to 93% and in the present simulation the adsorption rate to 90%.
