Abstract
Ternary diffusion coefficients of monoethanolamine (MEA) and N-methyldiethanolamine (MDEA) in aqueous solutions have been measured at 303.2, 313.2, and 323.2 K. The systems studied are aqueous solutions containing total amine concentrations of 2.5 and 4.0 kmol/m3 and each solution prepared with four different amine molar ratios. The main diffusion coefficients (D11 and D22) and cross-diffusion coefficients (D12 and D21) and the density and viscosity of the aqueous amine solutions are discussed and analyzed as a function of temperature and their concentration.
