The amine-based solvent 2-amino-2-methylpropanol (AMP) represents a promising potential absorbent for efficient CO2-capture. In this work, a numerical study of AMP in absorption/desorption loops at industrial scale was carried out. To evaluate the AMP performance, it was compared to the state-of-the-art solvent monoethanolamine (MEA). Sensitivity studies were performed to identify performance limiting and performance-enhancing factors. Subsequent optimisation revealed that replacement of MEA by AMP can reduce the energy requirements of CO2-capture units by 20% and the solvent consumption by 15%. (C) 2016 Elsevier Ltd.
