Global warming and its harmful implications is a major concern for the government and scientific community worldwide. CO2 being a greenhouse gas is considered to be a major contributor to the global warming. To reduce the anthropogenic emissions of CO2, capture of CO2 from the industrial processes is a must. The solvent based CO2 capture process is considered to be the most mature and promising technology to capture CO2 from the exhaust streams. Alkanolamines are the most widely used solvents in the CO2 capture processes. However, they are energy intensive and there are still needs for development of novel solvents that can make the CO2 capture technology more energy efficient. Amino acids have recently emerged as potential candidate to be used as an alternative in the CO2 capture technology. Since it is crucial to know the reaction kinetics of a particular amine solvent, before it can be suggested for chemical absorption of CO2, the main focus of this project is to investigate the reaction kinetics of two amino acids, namely; Glycine and L-Arginine with CO2 and their kinetic behavior when they are used in combination of an alkanolamine, such as MDEA, using the stopped flow technique. The experiments were carried out at a temperature range of 293-313 K and different amine/amino acid proportions for a total concentration ranging from 0.5 to 2 mole/L. The obtained kinetic results showed that amino acids and their blends of MDEA have great potential to be used as an alternative solvent for CO2.
