제목 Mass transfer of carbon dioxide in aqueous PEO solution of DEA
초록 Carbon dioxide was absorbed into aqueous polyethylene oxide(PEO) solution containing diethanolamine(DEA) in a flat-stirred vessel to investigate the effect of non-Newtonian rheological behavior of PEO on the rate of chemical absorption of CO2, where the reaction between CO2 and DEA was assumed to be a first-order reaction with respect to the molar concentration of CO2 and DEA, respectively. The volumetric mass transfer coefficient(kLa), which was obtained from the dimensionless empirical equation containing the properties of viscoelasticity of the non-Newtonian liquid, was used to estimate the enhancement factor due to chemical reaction. It was expressed that PEO with elastic property made the rate of absorption of CO2 accelerated by comparison of kL in the non-Newtonian liquid with that in the Newtonian liquid.
