Study on Density, Viscosity, and Thermodynamic Properties of MDEA and l‐Arginine Blends as a Potential Solvent for CO2 Capture

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT This study investigates the effect of adding l‐arginine (Arg) on the density and viscosity of aqueous solutions of methyldiethanolamine (MDEA). Densities and viscosities were measured at different MDEA (1, 2, and 3 M) and Arg concentrations (0, 0.01, 0.03, 0.05, 0.1, 0.15, 0.2 M) at a temperature range of 293.15–323.15 K.
