CO2 SOLUBILIZATION IN ALKALINE SOLVENTS
Keywords:
carbon dioxide (CO2) capture, CO2 capture, sodium carbonate, aqueous ammoniaAbstract
CO2 removal by chemical reaction of sodium carbonate (Na2CO3), and aqueous ammonia (NH3) shows promising absorption quality for CO2 removal and sequestration. Nevertheless, the solubility of CO2 by those alkaline solutions has been reported to be highly dependent on the temperature and the pH drop. This study focuses on screening the different solvents used for maximum CO2 solubility using pure CO2 based on 2 sets of experiments: First identifying the optimum temperature for distilled water which is considered as control under 3 different temperatures (20, 30 and 40?C). The Second was to identify the maximum CO2 capture from the solvents under two factors: the type of solvent used (Na2CO3, NH3), and their concentration (1-5%). The solubility behaviours of the CO2 in the solvents will be analysed according to pH change, CO2 capture rate, and CO2 capture efficiency using the water displacement method. The experimental results show that the control condition provided higher solubility than the proposed solvents; the CO2 removal using water value at 99.49% at 30?C while at the same condition, the highest removal efficiency for Na2CO3 value at a concentration of 3% 99.12% and NH3 at a concentration of 5%, 98.54% respectively.
