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 …

Esterification in Reactive Distillation Column Using Software Packages: A Review
Abstract: Abstract: Reactive distillation is the combination of reaction and separation in a same column. This represents an exciting alternative to traditional liquid phase chemical reaction processing. In reactive distillation, separation of products from unconverted reactants allows for better conversion, because produce elimination put out of place equilibrium and forces the reaction towards completion. The energy requirement of the conventional column is very and requires large recycling costs. Reactive Distillation is …
