Aqueous ethylaminoethanol blended solvents: Promising candidates for CO2 capture

Abstract

This paper reports the investigation of effect of temperature on physico-chemical properties of formulated solvent (comprises on ethylaminoethanol, N-methyl-2-pyrollidone, and K2CO3/KHCO3) and reaction kinetics of the absorption of CO2 in this formulated solvent. The physico-chemical properties were estimated by using a specific gravity bottle (density), an Ostwald's capillary viscometer (viscosity), and a stirred cell reactor (diffusivity and solubility of CO2 in formulated solvent). Similarly, a stirred cell reactor was used for the investigation of CO2 absorption kinetics by following a novel fall in CO2 pressure technique.
