Optimal Ratio of Methyldiethanolamine and Monoethanolamine Based on Regenerative Energy and Absorption Capacity Analysis

Chemical absorption using alkanolamine is the most used technique for carbon dioxide capture and storage (CCS). The energy required for regenerating the alkanolamine aqueous solution accounts for 70 - 80 % of the whole process. In this work, a new method was proposed to optimize the optimum ratio of...
