Comprehensive analysis of thermodynamic models for CO2 absorption into a blended N,N‐diethylethanolamine‐1,6‐hexamethyl diamine (DEEA‐HMDA) amine

“…The off gas passed through a water condenser to condense the amine solution in the exhaust gas After 6-h reaction, the sample was taken and analyzed by using the titration apparatus in previous work. 3 It is considered to the vapor-liquid equilibrium was identified once the CO 2 loading is stable, which could be determined as the equilibrium solubility of CO 2 . This experimental set-up was valeted by using 2M MEA were obtained at 313 K with an AARD of 1.06% as indicated in Figure 5.…”

“…Currently, researchers have discovered a variety of methods to capture CO 2 , such as membrane separation, low-temperature distillation, solid material adsorption, chemical absorption, etc. 3 The amine-based chemical absorption has not only a high decarbonization capacity and high selectivity, but also has a low energy consumption, which is considered as a promising technology for achieving a goal of CO 2 reduction. Monoethanolamine (MEA), methyl diethanolamine (MDEA), diethanolamine (DEA), Piperazine (PZ), and 2-amino-2-methyl-1-propanol (AMP) are the most widely used amine solvents.…”
