Removal of CO2 using Aqueous Blends of Amines by Chemical Absorption Method: Modeling
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 place through 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 …
