Abstract
Gas scrubbing using aqueous amine solutions is the most promising retrofit option for post combustion CO2 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 CO2 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% CO2. However, in presence of SO2 and O2 performance losses occur so that further investigations with degradation inhibitors, varied blend concentrations and blends containing other amines are of interest.
