Abstract
This work contributes new experimental viscosity data of both unloaded and CO2-loaded aqueous
monoethanolamine (MEA) solutions. In the first part of this paper, viscosity of unloaded MEA solutions at MEA
mass fractions between (0.5 and 1) is presented. Four different techniques for representing the viscosity of
unloaded MEA solution are discussed and compared. The second part of this work reports viscosities of CO2-loaded
MEA solutions at five different CO2 concentrations for MEA mass fractions of 0.50, 0.60, 0.70 and 0.80. These
data were correlated using an established method from the literature. In both cases, the dependence of viscosity
on temperature is also discussed.
