Efficiency comparison of novel [bmim][TCM] ionic liquid and MDEA amine solution for the capture of CO2 inside membrane contactor using CFD technique

Detrimental impacts of greenhouse contaminants’ emission (particularly CO2) to the atmosphere have recently endangered ecosystems, human well-beings and economies worldwide. This paper aims to employ a numerical simulation to evaluate the efficiency of 1-Butyl-3-methylimidazolium tricyanomethanide ([bmim][TCM]) ionic liquid (IL) and methyldiethanolamine (MDEA) amine solution for capturing CO2 inside the hollow fiber membrane contactors (HFMCs). Moreover, mapped meshing technique is utilized to compartmentalize the geometries of module into smaller dimensions to enhance the accuracy and reduce the discrepancy among the results. The validation of simulation has been performed via their comparison with experimental data. With the average relative deviation of almost (ARD) of almost 5 % between the simulation findings and experimental data, model validation has been corroborated. Additionally, this research studies the effects of some parameters including the velocity of gas mixture, module length and porosity on the capture yield of CO2.
