The utility of polyamine-based solvent-activators for the possible application in postcombustion CO 2 capture technology has drawn considerable attention recently owing to its higher loading capacity as well as superior kinetics. The current work involves a comprehensive experimental cum theoretical investigation on the equilibrium solubility of CO 2 pertaining to aqueous N-(3-aminopropyl)-1,3-propanediamine and its blends with Nmethyldiethanolamine and 2-amino-2-methyl-1-propanol. The analysis was conducted within the operating temperature and CO 2 partial pressure range of 303.2-323.2 K and 2-200 kPa, respectively. Two different mathematical models based on nonrigorous approaches such as equilibrium based modified Kent-Eisenberg (KE) model and a multilayer feedforward neural network model have been developed to correlate the CO 2 solubility data over a wide range of experimental conditions. Both the model predictions are wellvalidated with the experimental results. The reaction scheme as well as the prevalence of important reaction products was further confirmed with qualitative 13 C NMR as well as ATR-FTIR analysis. Apart from these some of the important thermally induced transport properties viz, density, viscosity, and surface tension of the aqueous single and blended systems were measured and correlated with various consistent empirical models such as Redlich-Kister and Grunberg-Nissan model while surface tension data are modeled using temperature-based multiple linear regression technique.

Innovative advanced solvent based capture processes (ASBCPs) employing sophisticated separation mechanisms have emerged as essential solutions that may dramatically reduce high energy requirement of CO 2 separation in capture plants. This study systematically characterises useful mechanisms of several such ASBCPs, being mostly at relatively low technology readiness levels. Based on improved understanding of these emerging ASBCPs it is shown how they can contribute to achieving energy efficiency benefits and thus increase CO 2 capture efficiency. It is followed by an analysis of practical examples of all ASBCPs recently presented in academic and patent literature. Finally, major challenges of discussed emerging ASBCPs are identified showing potential directions for further research and development. Overall, innovative ASBCPs employ very different mechanisms translating to different energy efficiency benefits in various CO 2 capture applications. The provided technological account along with the identified challenges may be useful for capture process developers which will be able to bring the most promising ASBCPs to higher technology readiness levels and finally they can be employed in the practice.
