Abstract
Abstract Gas scrubbing using aqueous amine solutions is the most promising retrofit option for post combustion CO 2 capture today. Therefore, new solvents combining favorable characteristics are developed to optimize the overall performance and replace the benchmark process with MEA. This work reports absorption rates and CO 2 loadings of fresh and regenerated MEA, EDA, AMP solutions and EDA-AMP blends under different gas compositions. EDA, AMP and their blend show advantageous characteristics during absorption of 100% CO 2 . However, in presence of SO 2 and O 2 performance losses occur so that further investigations with degradation inhibitors, varied blend concentrations and blends containing other amines are of interest.
