摘要：

The viscosities of carbonated N-methyldiethanolamine (MDEA)-monoethanolamine (MEA) aqueous solutions were measured, with the temperature, mass fraction of amines and CO2 loading (alpha, mole number of CO2/mole number of MDEA + MEA) respectively ranging from 293.15K to 343.15K, 0.2 to 0.5 and 0 to 0.5. A modified Grunberg-Nissan equation was proposed for correlation and prediction of the viscosities of carbonated MDEA-MEA aqueous solutions. The effects of temperature, amine concentration and CO2 loading on the viscosities were demonstrated. (C) 2012 Elsevier B.V. All rights reserved.
