Abstract
The accurate design of carbon dioxide separation processes by the absorption method requires knowledge of the vapor-liquid equilibrium of aqueous alkanolamine systems. MEA (monoethanolamine) is widely used for the separation of carbon dioxide by the chemical absorption process. The equilibrium apparatus was tested by comparing the measured VLE data for the methanol+ethanol system with the literature data. The isobaric vapor liquid equilibrium_x000D_
data were measured for the water+MEA binary system by using a modified Stage-Muller equilibrium still with circulation in both phases. The vapor liquid equilibrium data of water+MEA were measured in the pressure range from 50.0 to 70.0 kPa and temperature range from 355.2 to 430.3 K. The measured data were correlated with the UNIQUAC and NRTL activity coefficient models.
