Over the last two decades, the looming catastrophe of climate change and pollution caused by different anthropogenic interventions has drew international attention. However, carbon capture and storage (CCS) systems, which were formerly thought to be a viable technology for averting this alarming future, are now regarded too expensive to implement, and their long-term environmental repercussions remain unknown .The importance of this work in eliminating or reducing carbon dioxide emissions is underlined. In this work, an absorption technology .The mass transfer coefficient of carbon dioxide from a gaseous mixture (air, carbon dioxide) in blended solution Monoethanolamine (MEA), Diethanolamine (DEA), and Triethanolamine (TEA) in a packed bed reactor (PBR) was investigated in this study using absorption technology. The Plexiglas packed bed stood 75 cm high and had a 10 cm internal diameter.At various operating conditions, such as gas flow rate, air flow rate, and liquid flow rate, the overall mass transfer coefficient (K Ga) was studied. Gas flow rates of 5, 10, and 15 L/min, air flow rates of 80,90, and 100 L/h, and liquid flow rates of 150,300,450 mL/min were used. This experiment was carried out utilizing a continuous procedure with the assistance of a centrifugal pump. During the absorption experiment, high-performance gas chromatographic (GC) was used to assess CO2 loading. The greatest value of total mass transfer coefficient (K Ga) was 0.084 S-1based on the experimental results, which demonstrated that loading CO2 in the range of 0.511–2.479 (mole CO 2 /mole amine).
