A new CO2 absorption data for aqueous solutions of N-methyldiethanolamine + Hexylamine

Abstract : The aim of this work is to develop a new chemical solvent for CO2capture and compare its performance with a reference based solvent MDEA (MethylDiEthanolAmine). A mixture of MDEA and Hexylamine activator (HA) is designed to improve the performance of the process and allow a substantial gain in terms of energy regeneration and reducing the cost of capture. New CO2 absorption data is obtained using a Lewis cell gas-liquid interface at 298, 313 and 333 K with mass concentrations MDEA 37 wt%+ HA 3 wt%,MDEA 35 wt%+ HA 5 wt% and MDEA 33 wt%+ HA 7 wt%, to assess the CO2 absorption flux and the absorption capacity of the new solvent. Our results show that for the mixture of MDEA 37 wt%+ HA 3 wt%, the kinetics reaction is fast with reduced activation energy compared to that of MDEA 40 wt%.
