Abstract
The CESAR1 solvent is a non-proprietary blend of 2-amino-2-methylpropanol (AMP) and piperazine (PZ), that has been extensively studied as a good candidate for post-combustion CO2 capture. It offers lower energy demand, more flexibility of operation and higher chemical stability than the earlier benchmark solvent, 30wt% ethanolamine (aq.) 1. The Horizon Europe project AURORA aims to close the remaining knowledge gaps associated with post-combustion CO2 capture using the CESAR1 solvent and a core topic in that work is deepening the understanding of CESAR1 solvent stability and the consequences of CESAR1 degradation.
