Carbon capture via wetted wall column: A comparative analysis of aqueous sodium glycinate and aqueous ammonia
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 a...

| Summary: | 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. |
