Summary: | Amino acid salts are of great interest as potential solvents for CO2 capture because they are considered to be environmentally friendly. In the present paper, results of experimental work with a pilot plant with 3.5 M potassium sarcosine are presented. Both absorption kinetics and energy consumption are studied. The results show clearly that the amino acid salt system has a high absorption rate and high energy requirement compared to 30 wt-% MEA. The solvent system has been modeled in an in-house tool and simulation results are compared with the some performance results obtained experimentally. The soft-model approach developed for the potassium sarcosine solvent systems represents the absorber fairly well, while it seems to be too simplified to represent the stripper conditions. The present study is part of an ongoing EU project, Cesar. |
