Experiment and model for the viscosity of carbonated 2-amino-2-methyl-1- propanol-monoethanolamine and 2-amino-2-methyl-1-propanol-diethanolamine aqueous solution

摘要

The viscosities of carbonated 2-amino-2-methyl-1-propanol (AMP)-monoethanolamine (MEA) and AMP-diethanolamine (DEA) aqueous solutions were measured by using a NDJ-1 rotational viscometer. The temperature, total mass fractions of amines and CO_2 loading respectively ranged from 303.15 K to 323.15 K, 0.3 to 0.4 and 0.1 to 0.5. The experiments were satisfactorily modeled by using a modified Grunberg-Nissan equation. The effects of temperature, mass fractions of amines and CO_2 loading on the viscosities of carbonated aqueous solutions were demonstrated on the basic of experiments and calculations.
