Comparison of chemical solvent for co2 removal from power plant using amine scrubbing process

This research is aims to compare monoethanolamine (MEA), diethanolamine (DEA), and N-methyldiethanolamine (MDEA) solvents to achieve higher CO2 removal efficiency in absorber column by varying some process parameters including amine concentration, lean solvent flow rate and temperature. Process mode...
