This study evaluated the efficacy on CO2 absorption of varying concentrations of sodium glycinate solutions at constant flow rates and temperature using a wetted-wall column. The concentrations studied were 1%, 3%, and 6% (w/w) at a temperature range of 10ºC – 15ºC, solvent flow rate of 100 mL/min and simulated flue gas flow rate of 2 L/min. The findings indicated a direct proportionality between the concentrations of the solvent used and the percentage CO2 absorbed. The mean percentage CO2 absorbed steadily increased from 24.61% to 60.58% and up to 85.26% while the mean overall mass transfer coefficient increased from 0.0717 to 0.236059 and up to 0.4878 mmol/m2·s·kPa. © School of Engineering, Taylor’s University.
