Kinetic Study of the Catalytic Desorption of Carbon Dioxide (CO2) from CO2-Loaded Monoethanolamine (MEA) and Blended Monoethanolamine-Methyldiethanolamine (MEA-MDEA) during Post Combustion CO2 Capture from Industrial Flue Gases
… CO2 from CO2-loaded aqueous solutions of single monoethanolamine (MEA), and monoethanolamine blended with methyldiethanolamine (MEA-MDEA) during the post-combustion capture of CO2 from industrial flue gases. The experiments were performed over γ-Al2O3 and HZSM-5 catalysts in a complete absorber – …

Carbon capture technology for natural gas power plants: selection techniques and implementation strategies for a real-world scenario
… technology was a post-combustion capture using monoethanolamine (MEA). However, there were a number of technologies that were on the Pareto frontier and could have been equally good options, given alternative stakeholder requirements. The most beneficial strategy to implement this technology was …
