Abstract

CO2 capture using amine-based absorption is the most mature technology to decarbonize carbon intensive industries, Bui et al. (2018). Research has been focused on studying solvents that are stable, environmentally sustainable and energy efficient. The CESAR1 solvent, an aqueous blend of 3 M 2-amino-2-methyl-1-propanol (AMP) and 1.5 M piperazine (PZ) is considered now the benchmark solvent for amine-based CO2 capture, Feron et al. (2020). However, one of the main challenges to the commercialization of the process is the potential solvent emissions, Buvik et al. (2021). In particular, amine aerosol emissions impose a risk to the environment and the human health, since the conventional water wash alone may not be enough to contain these emissions, (Mertens et al., 2014).

Keywords: Amine-based CO2 capture, CESAR1, Aerosol modeling, emissions mitigation.
