Abstract


Viscosities of liquid solutions of monoethanolamine (MEA), water (H20), and carbon dioxide (CO2) have been measured. The mass fraction of MEA was (10, 20, 30, 40, and 50)%, and CO2 loading values was between (0.1 to 0.5) mol CO2/mol MEA. The operating temperature was varied between (20 to 150)°C. The available literature data for temperature range (25 to 80)°C for mass fraction of (20, 30 and 40)% were used to compare the measurement data. The dynamic viscosity increase with the increase of CO2 loading and decrease with an increase of temperature. The measured data were compared with the data predicted from available regression equation for certain temperature range. Agreement between measured data and the correlation data was satisfactory.
