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) in a bubble column reactor (BCR) . The bubble column reactor(BCR) was made of Plexiglas with 1.5 m high and 0.1 m inside diameter.
The overall mass transfer coefficient ( was evaluated at different operating conditions , gas flow rate, air Flow rate ,liquid flow rate .Where the gas flow rates were 10, 15 and 20 L /min , air flow rate 100,150 and 200 L/h ,and liquid flow rate 5 ,10,15 L /min . This experiment by using continuous process with helping centrifugal pump . High-performance gas chromatographic (GC) was performed to evaluate loading during absorption experiment . The experimental results have shown that the loading in range of 0.581-1.367 (mol /mole amine),and the maximum value of overall mass transfer coefficient ( KG) was 0.04 S-1 .
