Abstract
Amine-based absorption is currently the most advanced and cost-effective means of postcombustion CO2 capture among the different technologies that can be used (Dutcher et al., 2015). Much work has been done to reduce energy consumption, which constitutes one of the major penalties to the absorption process. Therefore, when it comes the need to develop new energyefficient solvents for the successful implementation of CO2-capture worldwide. An alternative to the widely used ethanolamine (MEA) is an aqueous solution of 2-amino-2-methyl-1-propanol (AMP), promoted with piperazine (PZ). It has been demonstrated that an aqueous blend 3.0 M AMP/ 1.5 M PZ, known as CESAR1, exhibits lower energy consumption (Mangalapally and Hasse, 2011), lower degradation rates (Lepaumier et al., 2009), and higher loading capacity
compared to MEA (Choi et al., 2007).
Keywords: post-combustion capture, chemical absorption, absorption kinetics.
