Abstract

Carbon capture from point source emissions has been recognized as one of the several strategies necessary for mitigating unfettered release of greenhouse gases (GHG’s) into the atmosphere to prevent global warming. To keep the GHG’s at manageable level, large decrease of CO2 should take placethrough capture technologies like chemical absorption. Alkanolamines such as monoethanolamine (MEA), diethanolamine (DEA), and N-methyldiethanolamine (MDEA) have been used for gas treating at industries. There has been a growing interest today for gas treating by using blended amines. The mixed amine systems, which combine the higher equilibrium capacity of the tertiary amine with the higher reaction rate of the primary or secondary amine, can bring about considerable improvement in gas absorption like MDEA/MEA and MDEA/DEA are compared based on the reaction kinetics. Modeling is applied for absorption rate constants for the above blended amines using MATLAB.
