| Abstract | ||||
| In this work, an absorption technology was used actually to investigation the mass transfer coefficient of carbon dioxide from a gaseous mixture (air, carbon dioxide) in blended solution Monoethanolamine (MEA) and Diethanolamine (DEA) and Triethanolamine (TEA) in a packed column reactor (PCR) . The packed column was made of Plexiglas with 75 cm high and 10 cm inside diameter .The overall mass transfer coefficient (KGa) was evaluated at different operating conditions , gas flow rate, air Flow rate ,liquid flow rate .Where the gas flow rates were 5, 10 and 15 L /min , air flow rate 80,90 and 100 L/h , liquid flow rate 400 ,450,500 mL /min . This experiment by using semi-continuous process with helping centrifugal pump . High-performance gas chromatographic (GC) was performed to evaluate CO2 loading during absorption experiment . The experimental results showed that loading CO2 in the range of 0.461–9.541 (mole CO2 /mole amine), and the maximum value of overall mass transfer coefficient (KGa) was 0.0354 S^-1 | ||||
