In this study, the removal of carbon dioxide (CO2) that has a huge contribution to global warming from gas
emissions was performed using absorption method. Effect of operational parameters such as temperature and
gas flow rate on the absorption capacity (g CO2/kg solvent and mol CO2/mol MEA) was investigated in a bubble
column reactor with a semi-batch operation. The monoethanolamine (MEA) was used as a solvent and absorption
capacity was determined at different gas flow rates (2.5 and 5 L/min) and temperatures (25-35-45 oC). Because of
the study, absorption capacities of 74.71 g CO2 / kg MEA and 0.51 mol CO2/mol MEA were obtained at 5 L / min
gas flow rate, 25oC and 20% solvent concentration. The absorption capacity increases as the temperature
decreases and as the flow rate increases. Because of the study, it can be concluded that the capture of CO2 into
the MEA solution at bubble column can be successfully achieved with high absorption capacity.
